Citrix XenApp Interview Questions and Answers Part2

QUESTION: 1

Scenario: A XenApp administrator must recommend a database option for the new

XenApp 6.5 data store. The new farm will have more than 100 XenApp servers and 500

published resources, support more than 5,000 concurrent users and have two zones

separated by a WAN connection. Which two database options should be administrator

recommend? (Choose two.)

A. IBM DB2 9.7

B. Oracle Enterprise 1.1

C. Microsoft SQL Server 2008

D. Microsoft SQL Server Express 2008

Answer: B, C

Explanation:

SQL Express is a free version that only supports small environments. Obviously 100

xenapp servers, 500 published applications, 5,000 concurrent users is a large

environment.

QUESTION: 2

Scenario: The administrator of a small XenApp server farm has configured end-to-end

encryption between the XenApp servers and user devices by setting up Access Gateway

VPX. Session Reliability is enabled in the farm with default settings. Over which port

will published applications be delivered?

A. 80

B. 443

C. 1494

D. 2598

Answer: B

Explanation:

I think the answer should be 443 because of the CAG vpx is set up and then all traffic is

ported to 443. Also the 2598 traffic is directed to 443.

QUESTION: 3

Scenario: The administrator of a XenApp Enterprise Edition server farm is configuration

Single Sign-on for the users of the farm. The Citrix license server was installed with the

default vendor daemon and console Web port numbers, but NOT the default license

server port number. Of the port numbers that are in use in the XenApp server farm, which

one should the administrator specify for the license server during Single Sign-on

configuration?

A. 443

B. 7279

C. 8082

D. 27009

Answer: D

Explanation:

v4 - updated

This is a trick question.

By default the daemon and console use ports 7279, and 8082, so answers B and C are

incorrect, because you can't have 2 things using the same port By default the license

server uses 27000, and as you can see below, by default SSO uses 27000, but the

question says 27000 was NOT used. Since 443 requires certificates and the question

doesn't mention that, the only possible port left is 27009

1Y0-A20

License server port number is 27000

Vendor daemon port number is 7279

Console Web port is 8082

QUESTION: 4

In building out a new XenApp environment, an administrator places the Secure Gateway

and Web Interface in the DMZ. What must the administrator do to secure the traffic to

the XML Broker?

A. Change the XML traffic port to a non-standard assignment.

B. Use the SSL Relay tool to encrypt traffic to the XML Broker in the farm.

C. Place the XML Broker in the DMZ and encrypt the traffic between them.

D. Use encrypted ICA to communicate between the XML Broker and the Web Interface.

Answer: B

QUESTION: 5

An administrator needs to install a XenApp 6.5 server to act as an additional dedicated

data collector. After installing XenApp on the new server, the next step is to configure it

by enabling the __________.

A. Session-host mode only

B. Controller and Session-host modes

C. data collector and XML Broker host mode

D. data collector and XTE Service host mode

Answer: B

Explanation:

Only during setup you can set the setup type: select session-host only (doesnt act as a

data collector) or controller and session-host. Option C&D are invalid.

QUESTION: 6

Scenario: An administrator manages a XenApp farm that uses Citrix Provisioning

Services to automate the addition of XenApp servers to the farm. The administrator must

implement a solution to automate the addition of new servers to the published resources,

load evaluators, Citrix polices and load balancing policies. Which two should the

administrator configure to meet the requirements of the scenario? (Choose two.)

A. Zones

B. Policies

C. Worker group

D. Load evaluators

Answer: B, C

Explanation:

A worker group is a list of xenapp servers. Rather than manually adding new servers to a

published application, for example, you could simply use a worker group and when you

1Y0-A20

add a new xenapp server to a worker group, it's automatically added to any published

applications that use that group.

QUESTION: 7

Which Citrix service should an administrator monitor when troubleshooting issues with

Session Reliability?

A. IMA

B. XML

C. XTE

D. MFCom

Answer: C

Explanation:

Session Reliability is performed by the XTE service

http://support.citrix.com/article/CTX104147

QUESTION: 8

Scenario: An administrator has finished installing the first server in a new farm and is

now creating the data store. The farm will consist of five servers and needs to support

about 50 users. The company wants this installation to be as cost-effective as possible.

What is the best option for a database system that would support this farm effectively?

A. Microsoft Access

B. Microsoft SQL Server

C. Oracle Database System

D. Microsoft SQL Server Express

1Y0-A20

Answer: D

Explanation:

50 users is a small environment, therefore SQL Express would be the best choice. Notice

the question asks "most cost-effective" - SQL Express is FREE

http://support.citrix.com/proddocs/topic/xenapp65-planning/ps-planning-datastore-introv2.

html

Microsoft SQL Server and Oracle are suitable for any size environment and are

recommended for all large and enterprise environments. When deploying large farms

across a WAN, you can obtain a performance advantage by replicating the data store and

distributing the load over multiple database servers. SQL Server and Oracle are suitable

for large farms and support replication. Do not install XenApp on the SQL Server or

Oracle database server. SQL Server Express is suitable for all small and many medium

environments located in one physical location, which do not have branch offices across a

WAN.

QUESTION: 9

In order for an administrator to download a license from the company's mycitrix.com

portal, the administrator must be added _________.

A. as a Citrix Administrator in the AppCenter

B. into the contacts for the company in mycitrix.com

C. to the Purchasing Active Directory group in the company

D. as a Domain Administrator in the company's Active Directory

Answer: B

Explanation:

http://support.citrix.com/article/CTX130126 You must be logged on to MyCitrix with a

user name and password associated to an Administrator of the account where you need to

make the restricted toolboxes available to other contacts. When allowing contacts to

access unrestricted toolboxes, all contacts within the account are able to view or use the

toolboxes. The system does not allow an administrator to select only certain contacts to

view these toolboxes. The access is available to all or to none. If you need to allow only

1Y0-A20

certain contacts access and do not want to provide all contacts access, Citrix recommends

that you add such contacts to the Administrators group.

QUESTION: 10

Scenario: A farm contains six servers with one shared data collector that has a custom

load balancing policy to limit the number of connections. An administrator needs to add

more users to the farm, which will result in adding on four more servers for a total of 10.

As most users in the farm use a CAD application, the administrator understands that

resource needs will increase. Which step should the administrator take to maintain farm

integrity?

A. Dedicate two new servers as data collectors and set them as Most Preferred in the

election.

B. Dedicated one new server as the dedicated data collector and the current data collector

as its backup.

C. Dedicate three new servers as shared data collectors and assign Most Preferred in the

election panel.

D. Dedicate a new server as a second shared data collector and assign Most Preferred in

the election panel.

Answer: B

Explanation:

The resources a data collector uses increase based on users and servers. Since more users

and servers are being added to the farm, a dedicated server should be used just as a data

collector.http://support.citrix.com/proddocs/topic/xenapp65-planning/ps-planning-datacollectors-

planning-v2.html

When planning for data collectors, consider:

If you need a dedicated data collector

If you do not need a dedicated data collector, which infrastructure services can share

the same server

If you need a zone in each geographic region, which means that you need data

collectors for those regions as well To maintain consistent information between zones,

data collectors relay information to all other data collectors in a farm, creating network

traffic. In general, data collector memory consumption increases as farm size increases.

However, it is not significant. For example, the Independent Management Architecture

service running on the data collector typically uses 300 MB on a 1000 server farm.

Likewise, CPU usage is not significant. A data collector hosted on a dual-processor

server can support over 1000 servers in its zone. In general, CPU usage increases as the

number of servers in a zone increases, the number of zones increases, and the number of

users launching applications increases. On most networks, Citrix recommends reducing

1Y0-A20

the number of data collectors and zones. For example, if you have a farm with 100

servers in one location, Citrix recommends having one zone with a dedicated data

collector (although you can have backup data collectors). Citrix recommends installing

XenApp on the server you want to host the data collector functionality and, after

installing other member servers, configuring a server as the backup data collector.

QUESTION: 11

Scenario: An administrator is creating a new XenApp farm. The farm will use hosted

applications and applications streamed using Microsoft App-V technology. Both

Microsoft Windows and Apple OS X computers are in use in the environment.

Management requires an automated process to deliver all necessary clients and plug-ins.

Which two components should the administrator use to automate the process of

delivering and updating client plug-in? (Choose two.)

A. Microsoft Group Policy

B. Citrix Receiver Updater

C. Citrix Merchandising Server

D. Apple Enterprise Management Software

Answer: B, C

Explanation:

Group policy cannot be used for Apple computers, so option A is invalid Citrix Receiver

for Windows, Receiver for Mac, and Merchandising Server are components of the Citrix

Delivery Center solution. While Citrix Delivery Center provides the application delivery

infrastructure to the IT administrator, Citrix Merchandising Server and Citrix Receiver

for Windows work together to streamline the installation and management of application

delivery to the user desktops. Merchandising Server provides the administrative interface

for configuring, delivering, and upgrading plug-ins for your users' computers.

QUESTION: 12

Scenario: A Citrix administrator manages a XenApp farm with 3,000 users. The users run

the same set of applications every day. Users complain that Application B takes a long

time to launch after they exit Application A. The administrator is required to implement a

solution to speed up application launch. What should the administrator do in order to

ensure that users are able to launch Application B quickly after they exit Application A?

A. Configure Session Linger

B. Set Linger Disconnect Time Interval to 0

1Y0-A20

C. Set Pre-launch Terminate Time Interval to 0

D. Create a Pre-launch session for Application B

Answer: A

Explanation:

This question is verifying you know the difference between session linger and pre-launch

pre-launch loads the ICA session when the user logs into the Citrix Receiver, not when

they launch an application. However, when the application is closed the session is closed

as well. If the application is reopened there is a delay, which is what this question says is

happening. Session linger keeps the session open when an application is closed. If the

application is reopened, or if another application is opened, it is much quicker. A good

demonstration of the differences is at http://vimeo.com/33426922

QUESTION: 13

Scenario: Users working from a remote branch office using XenApp are reporting that

Flash content is NOT displayed on an internal web page. Branch office users have NO

direct connection to the internet. Other Intranet sites are unaffected. Which two steps

could the administrator take to resolve the issue without impacting Flash performance?

(Choose two.)

A. Upgrading the Receiver client on the users PC to version 13.

B. Create a XenApp policy to enable Flash redirection for remote users.

C. Downgrade the version of Internet Explorer on the XenApp server to version 7.

D. Enable server-server content fetching policy on the client device using the supplied

ADM file.

E. Add the URL of the intranet site to a Flash server-side content fetching URL list

policy setting.

F. Uninstall the Flash player on the XenApp server, and install the 10.1 Flash player or

later on the client.

Answer: D, E

Explanation:

The second generation of Flash Redirection can be configured to be backward compatible

with its legacy features, supporting user devices with earlier versions of the online plugin

(now the Citrix Receiver). Those devices can access the legacy Flash Redirection

features only. This is done by providing two separate virtual channels, one for each

generation of Flash Redirection, on the servers and user devices To use the backward

compatibility feature: On the server running Desktop Studio or AppCenter, enable the

1Y0-A20

Citrix User Policy setting Flash backwards compatibility. On the user device, enable the

Enable HDX MediaStream for Flash on the user device setting, selecting the Always or

Ask options. To identify Web sites for server-side content fetching: Flash Redirection

downloads Flash content to the user device where it is played. The Flash server-side

content fetching URL list setting allows you to specify Web sites whose Flash content

can be downloaded to the server then sent to the user device. While server-side content

fetching works with most Internet sites, it is intended for use with Intranet sites and

internal Flash applications. http://support.citrix.com/proddocs/topic/xendesktop-als/hdflash-

QUESTION: 14

Scenario: An administrator needs to prepare a group of XenApp 6.5 servers for a

scheduled maintenance window. The servers need to accept connections from users that

already have existing sessions but disallow any new connections. The administrator also

needs to ensure that the servers remain in maintenance mode after the software updates

are performed, which require multiple restarts. Which setting can the administrator use

from the AppCenter?

A. Prohibit logons only

B. Drain until next restart

C. Allow logons and reconnections

D. Prohibit logons until server restart

E. Prohibit logons and reconnections

Answer: A

Explanation:

v4 changed answer to A Citrix recommends that you drain the server slowly by denying

new logons (rerouting them to other servers), but allowing users to reconnect to

disconnected sessions and close applications cleanly, thus preventing loss of user data.

QUESTION: 15

Users of a medical application are complaining of poor quality images when viewing Xray

scans. The administrator should create a XenApp policy to _________.

A. enable image caching

B. set the Lossy Compression Level to None

C. set the Progressive Compression level to low

D. set the Heavyweight Compression level to Disabled

Answer: B

Explanation:

http://support.citrix.com/proddocs/topic/xenapp5fp-w2k8/ps-console-policies-rulesspeedscreen.

html Compression Level This setting controls the normal lossy compression

level used over client connections that are limited in bandwidth. In such cases, displaying

images without compression can be slow. The Compression level setting defines the

degree of lossy compression used on images. For improved responsiveness with

bandwidth- intensive images, use high compression. Where preserving image data is

vital; for example, when displaying X-ray images where no loss of quality is acceptable,

you may not want to use lossy compression.

QUESTION: 16

Scenario: A user opens a session to Server A to use a word processing application at

18:00. After 45 minutes of working with the word processing application, the user then

launches an email client application, which opens a new session on Server B. Upon

review of the environment, the administrator confirms that both applications are

1Y0-A20

published with the same parameters for audio, screen size, color resolution and

encryption. Which three possible reasons could have prevented Session Sharing from

occurring? (Choose three.)

A. The email client application is NOT installed on Server A.

B. The email client application is only published from Server B.

C. The number of instance of the email client application that can be run is limited.

D. Server A is reporting a full load, preventing the email client application from

launching.

E. Server A and Server B are in different vLAN; the vLAN of Server B has more

capacity than the vLAN of Server A.

Answer: A, B, D

Explanation:

This question tests your knowledge of Session Sharing

http://support.citrix.com/article/CTX159159

vLans are virtual LANs; each vLAN can be thought of as a seperate domain. If each

server was in a different vLan they would be in different XenApp Farms so answer E is

incorrect. happens BEFORE load balencing so answer D is incorrect

QUESTION: 17

XenApp users need to be able to move between client devices and reconnect to both

active and disconnected sessions. What action must an administrator take to enable this

behavior?

A. Install Web Interface and XenApp with the default settings.

B. Disable Workspace Control on each Web Interface server.

C. Configure a XenApp policy to enable the Smooth Roaming feature.

D. Ensure that the Web Interface server is in the same domain or forest as the XenApp

farm.

Answer: A

Explanation:

Workstation control (smooth roaming) are enabled by default on the XenApp Website

and Services Site.

1Y0-A20

I could not find a policy for Smooth Roaming.

QUESTION: 18

An application is published to users using the 'Streamed to client' delivery type. Which

two plug-in are required and where are they required for this application? (Choose two.)

A. Online plug-in on the client

B. Offline plug-in on the client

C. Offline plug-in on the XenApp server

D. Online plug-in on the XenApp server

Answer: A, B

Explanation:

http://support.citrix.com/proddocs/topic/xenapp65-publishing/ps-stream-plugindecide.

html Streamed to client desktops. With this method, you make available the full

set of application streaming features. You can publish applications as "streamed to client"

or any other method for streaming. When you stream applications directly to client

desktops, some of the application files are cached locally and the application runs using

the resources of the user device. Install both the CitrixReceiverEnterprise.exe and

CitrixOfflinePlugin.exe on user devices.

QUESTION: 19

Scenario: A company has 10 XenApp servers. The administrator has changed the

recovery action of the MS Print Spooler Test of Health Monitoring and Recovery to

prohibit logons and connections to the server. Users report printing problems when

connecting to three of the XenApp servers. Using Health Monitoring and Recovery to

allow additional XenApp servers to be excluded from load balancing, the administrator

should change the __________.

A. minimum percent of online servers default value of 5 percent

B. maximum percent of offline servers default value of 5 percent

C. minimum percent of online servers default value of 10 percent

D. maximum percent of offline servers default value of 10 percent

Answer: D

Explanation:

http://support.citrix.com/proddocs/topic/xenapp6-w2k8-admin/ps-maintain-monitorserver-

perf.html

Maximum percent of offline servers (10 percent by default). Use this setting to specify

the number of servers that the Health Monitoring and Recovery feature can exclude from

load balancing.

QUESTION: 20

Scenario: A server farm has three policies using the Client IP address and User filters.

- Policy A (priority 1) prevents client IP address in the 208.29.80.* range from accessing

network and optical drivers. All other settings are disabled.

- Policy B (priority 2) prevents client IP address in the 208.29.85.* range from accessing

network, client and removable drives. No other settings are configured.

- Policy C (priority 3) allows all domain users to access network, client, optical and

removable drives. All other settings are disabled. Which drives will be available to a

domain user accessing the server farm from a client using the 208.29.85.152 IP address?

A. No drives

B. Optical drives

C. Client and removable drives

D. Network, client and removable drives

E. Network, client, optical and removable drives

1Y0-A20

Answer: B

Explanation:

Policy B restricts client and removable drives, so that only leaves optical drives

QUESTION: 21

Scenario: A server farm has three policies applied using the User filter.

- Policy A (priority 1) denies domain users access to client and removable drives. No

other settings are configured.

- Policy B (priority 2) allows domain users to access optical drives. No other settings are

configured.

- Policy C (priority 3) allows domain users to access network, client and removable

drives. No other settings are configured. Which drives will be available to a domain user

in the environment?

A. No drives

B. Network drives

C. Network and optical drives

D. Network, client and removable drives

E. Network, client, removable and optical drives

Answer: C

Explanation:

Because Policy A denies client and removable drives, the only ones left are network and

optical drives.

QUESTION: 22

Scenario: Management requires that video conferencing is implemented on all of the

desktops, including video, sound and a webcam, in the three training rooms on the

education floor of the corporate building. Quality is of very high importance. The IT

department decided to implement video conferencing using XenApp. Multimedia

conferencing and Windows Media Redirection have been enabled and configured for the

XenApp servers. The latest Citrix Receiver for Windows is installed on all of the

desktops. Which three steps should the administrator take to meet the needs of the

scenario? (Choose three)

A. Publish Microsoft Office Premium 2007 in the XenApp farm.

1Y0-A20

B. Publish Microsoft Office Communicator 2007 in the XenApp farm.

C. Install Microsoft Office Communicator Server 2007 on a XenApp server.

D. Install one webcam on each desktop and use the manufacture's drivers.

E. Install one webcam on each desktop and let Windows find the appropriate driver.

F. Install Microsoft Office Communication Server 2007 on a server that is NOT running

XenApp.

Answer: B, D, F

Explanation:

Multimedia Conferencing Policy help file:

Allows or prevents support for video conferencing applications. By default, video

conferencing support is enabled. To use multimedia conferencing, make sure the

Windows Media Redirection setting is enabled.

* When using multimedia conferencing, make sure the following items are present:

* Manufacturer-supplied drivers for the web cam used for multimedia conferencing must

be installed.

* The web cam must be connected to the client device before initiating a video

conferencing session. XenApp uses only one installed web cam at any given time. If

multiple web cams are installed on the client device, XenApp attempts to use each web

cam in succession until a video conferencing session is created successfully.

* An Office Communicator server must be present in your farm environment.

* The Office Communicator client software must be published on the server. Related

QUESTION: 23

A Citrix XenApp administrator needs to apply a policy to all users regardless of

connection type. Which type of policy should the administrator create?

A. Unfiltered User policy

B. Unfiltered Computer policy

C. User policy filtered by worker group

D. Computer policy filtered by worker group

Answer: A

Explanation:

By default, XenApp provides Unfiltered policies for Computer and User policy settings.

The settings added to this policy apply to all connections.

QUESTION: 24

Scenario: A Citrix administrator manages a XenApp farm and applications are delivered

through one Web interface. The administrator is required to apply a policy to all users

accessing the XenApp farm through the Web Interface. The administrator should filter

the required User policy by ________ .

A. User

B. Group

C. Client Name

D. Worker Group

Answer: C

Explanation:

Since the policy needs to be applied to all users, it should be applied to the Domain Users

Group, since by default every user will belong to that group. You could also put every

user in an OU, but for this question OU is not once of the choices. You can filter user

policies by:

QUESTION: 25

Scenario: A XenApp administrator needs to publish an application that will be streamed

to traveling users so they launch the application when they are NOT connected to the

network. The administrator also needs to provide the published application over an ICA

connection. The user devices have been equipped with the appropriate plug-ins. Which

setting should the administrator choose when publishing the application?

1Y0-A20

A. Streamed to client

B. Installed application

C. Accessed from a server

D. Streamed if possible, otherwise accessed from a server

Answer: D

Explanation:

The application has to be streamed to be available offline on the client. Because of the

ICA Connection requirement, it also has to be available on the server.

QUESTION: 26

Scenario: A XenApp administrator has been tasked with delivering a new application to

the traveling sales force. The sales force will require access to applications even when

they do NOT have internal or network access. Which three steps are required to ensure

that the sales force can access their applications at all times? (Choose three.)

A. Install the offline plug-in on the servers.

B. Publish the application as streamed to client.

C. Install the offline plug-in on the sales force laptops.

D. Install the online plug-in on the sales force laptops.

E. Publish the application as accessed from a server, streamed to server.

F. Publish the application as accessed from a server, installed application.

Answer: B, C, D

Explanation:

The application has to be published as streamed to client for it to be accessible offline.

When the laptop has access to the xenapp server it uses the online plugin, when it doesnt

it uses the offline plugin. Before publishing an application to be streamed to client

desktops, complete the following tasks:

Install the Offline Plug-in locally, where it runs in the background to enable

application streaming.

Install the latest version of online plug-in locally.

To stream to client devices across a network protected by a firewall, configure firewall

policies to allow those applications access. After all of these tasks are complete, publish

the application as Streamed to client.

QUESTION: 28

Scenario: Users in an environment connect to the XenApp farm Linux based thin clients.

They reported that they are NOT able to access the computer-based training course

hosted on the XenApp server in the Microsoft Media Format (MMS). Windows-based

users are NOT reporting this issue. What could the administrator do to resolve this issue?

A. Disable host (server) to client redirection.

B. Request the Linux thin clients to use the Java client.

C. Ensure these thin clients have the latest receiver client for Linux.

D. Create a XenApp policy to enable HDX Flash redirection for the Linux thin clients.

task-v2.html

These URL types are opened locally when you enable this setting:

* Hypertext Transfer Protocol (HTTP)

* Secure Hypertext Transfer Protocol (HTTPS)

* Real Player and QuickTime (RTSP)

* Real Player and QuickTime (RTSPU)

* Legacy Real Player (PNM)

* Microsoft’s Media Format (MMS)

QUESTION: 29

Scenario: An administrator is in the process of profiling a streaming package. The

application needs unique user updates on a regular basis. How can the administrator

minimize his workload when updating the streaming package?

A. Enable user updates to allow users to download applications from the Internet and

store them in the user's root.

B. Enable user updates to allow users to send update requests notifications to the

administrator building the packages.

C. Enable user updates to allow users the ability to update the streaming package with

changes they make themselves.

D. Enable user updates to allow users to update the main streaming package with

changes that other users can benefit from.

Answer: A

Explanation:

http://support.citrix.com/proddocs/topic/xenapp-application-streaming-edocs-v6-0/psstream-

profile-security- yellowtail.html

Select the check box to permit executable files that are accessed through the profiled

application to run from the user profile root. If you profile the application with this

setting selected, the application can download vendor-supplied updates over the Internet.

Any updates are stored as part of the user root, so they are unique to that user. The next

time the user device connects to the profiled application on a server or file share, the

streamed application will not overwrite the updates, and the application runs using the

1Y0-A20

updates. Selecting this setting is recommended for streamed macromedia plug-ins, which

download extensions (DLLs) based on the content that is being processed. Also, some

applications decompress DLLs during runtime that need to run from the user root.

QUESTION: 30

Scenario: A XenApp administrator is tasked with delivering a new application to the

XenApp farm. During testing, the administrator finds that the application is incompatible

with existing applications installed on the XenApp servers. He CANNOT install the

application on the servers. The administrator is in the process of publishing this

application. Click the `Exhibit' button to view a screenshot of the Publish Application

window. Which streaming option should the administrator use to publish the application

so that iPhone mobile device users can access the application?

Exhibit:

A. Streamed to client

B. Accessed from a server - Streamed to server

C. Accessed from a server - Installed application

D. Streamed it possible, otherwise accessed from a server

Answer: B

1Y0-A20

Explanation:

v4 - previous answer was A, new answer B Iphones dont support streamed to client (as

far as I could tell), therefore you have to stream to the device by streaming to the xenapp

server. C&D are invalid because you CANNOT install the application on the xenapp

server - has to be streamed.

QUESTION: 31

Which steps should an administrator take to publish applications that will be accessed

through Web Interface and presented in different folders?

A. Publish the applications as Content instead of Applications.

B. Create a folder under the Application node and put the specific application in the

folder.

C. In the application properties, in the location section, change the working directory to

match the folder name.

D. In the application properties, in the Shortcut presentation section, fill in a name for

the Client application folder.

Answer: D

Explanation:

Once of the biggest misconceptions people have is that the folder in Appcenter is what

users will see. No! To have users see a folder you need to specify it here. The folder in

appcenter is only for administration it has no effect on publishing.

QUESTION: 32

1Y0-A20

Users in an environment need to be able to open Microsoft Office documents using the

software installed on the XenApp server even if the user has NOT started a Citrix session.

What must the administrator configure to meet the requirements of the scenario?

A. Offline streaming

B. File Type Association

C. Host (server) to client redirection

D. Client to host (server) redirection

Answer: D

Explanation:

Client to Server redirection is what Citrix call it when you redirect the local file

associations to the server to open a local file with a published app. You do not need to

manauly start an app for this to work.

QUESTION: 33

Scenario: A Citrix administrator manages a mixed environment consisting of desktops,

XenApp and XenDesktop. Management desires that:

- login times be decreased

- user profiles are stored in a centralized location

- user changes be saved

- user changes be made available to user sessions accessed from any desktop, XenApp

server or XenDesktop connection

Based on these requirements, which type of profile should the administrator implement?

A. Local

B. Roaming

C. Mandatory

D. Citrix Profile Management

Answer: D

Explanation:

Mandatory profiles do not allow user changes to be saved, so option C is incorrect Local

does not allow a centralized location, so option A is incorrect Mandatory profiles are not

1Y0-A20

accessible on desktop, xenapp, and xendesktop, and Mandatory profiles are very slow on

login time, so answer C is incorrect Only citrix profile management fit all options

http://support.citrix.com/servlet/KbServlet/download/19059-102-

665944/ProfileMgtCrossPlatformFAQ.pdf

"The short answer is yes. Profile management can apply a profile based on the

local desktop, XenApp, or XenDesktop, or any combination or multiples of these."

QUESTION: 34

Scenario: An administrator is setting up access for the User Support team. The

administrator wants to give this team access to manage user sessions so that they can

disconnect and either clear or log-off user sessions for troubleshooting purposes. Which

node would the administrator use in order to delegate these permissions in the

AppCenter?

A. Policies

B. Servers

C. Applications

D. Administrators

Answer: D

Explanation:

To delegate this permission add a new administrator and select custom, as shown below

QUESTION: 35

Scenario: An administrator receives word that the IT Manager wants the Domain Admin

group to have rights within the XenApp farm to help support the infrastructure. The

administrator agrees but wants to restrict them from publishing applications. In which

two ways could the administrator set these permissions? (Choose two.)

A. Map the Domain Admin's Active Directory group to a Custom Administrator's role in

the AppCenter and remove the Publish Application.

B. Add Each Domain Admin's Active Directory account to a Full Administrator's role in

the AppCenter and remove the Publish Application.

C. Map the Domain Admin's Active Directory group to a Full Administrator's role in the

AppCenter and uncheck remove the entire Publish Application.

D. Create a Custom Administrators group in Active Directory, map that to a Custom

Administrator's role in the AppCenter remove the Publish Application.

Answer: A, D

Explanation:

You can only give custom permission by adding a custom citrix administrator. Full

administration does NOT allow you to customize permissions

QUESTION: 36

A XenApp administrator discovers that a XenApp server which was previously deleted

from the AppCenter is still listed in the console. Which command can the administrate

run to force removal of the erroneous server record?

A. dscheck

B. dscheck /clean

C. dsmaint recover

D. dsmaint recreatelhc

Answer: B

Explanation:

http://support.citrix.com/proddocs/topic/xenapp5fp-w2k3/ps-commands-dscheck.html

When you run dscheck with the /clean option, the utility runs tests and removes

inconsistent data (typically servers and applications) from the data store. Because

1Y0-A20

removing this data can affect the farm’s operation, be sure to back up the data store

before using the /clean option.

QUESTION: 37

An administrator wants to configure configuration logging for two XenApp farms. Which

two tasks must the administrator configure to accomplish this? (Choose two.)

A. Configure separate MS SQL databases for each XenApp farm

B. Configure one MS SQL database for both XenApp farms to connect to

C. Enable configuration logging for each farm and connect to a single database.

D. Enable configuration logging for each farm and connect to two separate databases

Answer: A, D

Explanation:

You cannot share the same sql configuration database with 2 different farms. To enable

configuration loggin:

1. Open appcenter

2. Right click on the farm name, select farm properties

3. configure the database

QUESTION: 38

Scenario: An administrator has published Microsoft Excel on two identical servers and

has placed those servers in a worker group. There are 150 users in the environment, and

each server must be allowed to accept all 150-user sessions for failover purposes. All

users start work at 09:00 in the morning. The administrator also wants to prevent the

servers from failing due to excessive connection attempts during this logon time. What

can the administrator do to ensure that the server farm can meet these requirements?

A. Assign the default load evaluator to the worker group.

B. Assign the advanced load evaluator to the worker group.

C. Create a load balancing policy and assign it to the worker group.

D. Create a custom load evaluator and assign it to the worker group.

Answer: D

1Y0-A20

Explanation:

Default and custom load evaluator won't look at application load. Created a custom load

evaulator with application user load checked, and type in 150 as shown below. Apply it

to the worker group. This rule allows your load evaluator to calculate a load based on the

number of users accessing a specific published application on the attached server. When

the number of users accessing the published application is less than or equal to the

threshold value indicated here, Load Manager reports a load percentage based on the

threshold value.The valid range for this rule is 1 to 10000.

QUESTION: 39

Scenario: A server farm consists of dual and single processor servers. The administrator

wants to ensure that the dual-processor servers receive more sessions than the singleprocessor

servers. In addition the administrator wants to ensure that no server receives

more than 100 user sessions. In order to meet these requirements, the administrator must

assign the__________. (Choose the correct option to complete the sentence.)

A. custom load evaluator rule to all servers.

B. advanced load evaluator rule to all servers

C. custom load evaluator role to all dual processor servers

D. advanced load evaluator rule to all dual-processor servers

Answer: A

Explanation:

1Y0-A20

Default Load Evaluator:

- Load Throatling = High

- Server User Load = 100 (max number of user sessions)

Advanced Load Evaluator:

- CPU Utilization, Low = 10, Full = 90

- Load Throatling = High

- Memory usage, Low = 10, Full = 90

- Page Swaps, Low = 10, Full = 90

You need a custom load evaluator to decide load based on CPU and with a max number

of 100 user sessions.

QUESTION: 40

Scenario: An administrator wants users in their two regions to utilize the XenApp servers

in their own region to get the best performance from their applications but automatically

fail over to the alternate region. The administrator creates an Active Directory group for

each region. The administrator should create___________ and___________ (Choose the

correct option to complete the sentence.)

A. one worker group, one load balancing policy

B. two worker groups, one load balancing policy

C. one worker group, two load balancing policies

D. two worker groups, two load balancing policies

Answer: D

Explanation:

- One worker group for the servers in each of the two regions means two worker groups.

For example all the west coast servers would be in a west coast worker group and the east

coast servers in an east coast worker group.

- Each region needs to prioritise its own worker group first. For example if there were

two regions (east coast and west coast), the east coast region would have priority 1 for the

east coast worker group and priority 2 for the west coast worker group. Where as the west

coast region would need to have the oposite requirements (ie: priority 1 for the west coast

worker group and prioirty 2 for the east coast worker group).

Therefore since each region has different priority requirements they must have there own

Load Blanacing Policy, which means we need two load balancing polices not one.

QUESTION: 41

1Y0-A20

Scenario: An administrator has a server farm with five servers. The administrator wants

to limit the number of Microsoft Excel published application sessions that can be run in

the server farm. Which two steps could the administrator take to meet this requirement?

(Choose two)

A. Configure the Load Throttling rule.

B. Configure the Server User Load rule

C. Configure the Application User Load rule

D. Assign a load evaluator to the five servers.

E. Assign a load evaluator to the published application

Answer: C, E

Explanation:

In previous versions of XenApp you could apply a load evaluator to a server - no more!

You can only apply a load evaluator to 1) published application 2) worker group (by

creating a policy). Therefore option D is incorrect.

Assigning Load Evaluators to Servers and Applications Updated: 2011-08-04 To

participate in load management, each server or published application must have a load

evaluator assigned to it. Each server or published application can have only one load

evaluator attached. To assign a load evaluator to a XenApp server, configure the Load

Evaluator Name policy setting and filter the policy by worker group. You can assign load

evaluators that are available in any XenApp farm. The rules and their settings determine

how the load of a particular server or published application is managed. For example, if

you have a published application that uses a significant percentage of a server’s memory

and processing capabilities, you can add the Load Evaluator Name setting to a policy,

specify the Advanced load evaluator, and filter the policy by the worker group that

contains all the XenApp servers hosting the application. XenApp then distributes the

available memory and processor demand across the load-managed servers. When you

assign a load evaluator through Citrix policies, XenApp does not validate the load

evaluator name when the policy is applied to user sessions. Therefore, if the load

evaluator is later renamed or deleted, the load cannot be calculated. Instead, XenApp logs

an error to the Event Log and the affected servers report a load index of 10,000 (full

load). Additionally, the Usage by Server tab in the middle pane of the AppCenter does

not indicate the load evaluator is assigned. To ensure the policy references the correct

load evaluator name, modify the Load Evaluator Name policy setting and select the

correct load evaluator name from the list of available load evaluators. If the policy

containing the Load Evaluator Name setting is deleted, and no other policy applied to the

server specifies an alternate load evaluator, XenApp uses the Default load evaluator

instead. To assign a load evaluator to a server

1Y0-A20

Create a new Computer policy or select an existing Computer policy you want to

modify. Depending on the console you use to manage Citrix policies:

From the AppCenter, select the Policies node and then select the Computer tab.

From the Group Policy Management Editor, select Computer Configuration >

Policies > Citrix Policies.

From the settings list, locate the Load evaluator name policy setting and click Add.

Select a load evaluator from the drop-down list and then click OK.

Add the Worker Group filter to the policy and specify the worker group containing the

servers to which you want to assign the load evaluator.

To assign a load evaluator to a published application

From the AppCenter, select the Applications node in the left pane.

Select the published application to which you want to attach a load evaluator.

From the Actions pane, select Other Tasks > Attach application to load evaluator.

On the Assign Load Evaluator dialog box, select the load evaluator to attach.

QUESTION: 42

Scenario: A server farm has five servers which are members of the FARM worker group.

Multiple applications are published on the servers for use by over 100 employees. One of

the applications has only 10 licenses. What could the administrator do to allow only 10

employees to use that specific application at any given time?

A. Set the concurrent logon limit to 10.

B. Apply the limit user sessions policy using a filter.

C. Assign a load evaluator to the published application.

D. Apply the connection access control policy using a filter.

Answer: C

Explanation:

Option A is invalid because it would affect ALL published applications, the question is

very specific to 1 application. Option B would apply to ALL users because they all

belong to the same worker group Option C is correct is it only applies to the published

application

QUESTION: 43

Scenario: A server farm has 12 servers in the FARM worker group with more than 1,000

users and 20 published applications. Two of the published applications perform excessive

CPU context switches. What can the administrator do to ensure that the resourceintensive

applications will run optimally in the server farm?

1Y0-A20

A. Assign a load evaluator to the FARM worker group.

B. Assign a load evaluator to both resource-intensive applications.

C. Apply the multi-Steam policy to both resource-intensive applications.

D. Apply the session importance policy to both resource-intensive applications

Answer: B

Explanation:

v4 - answer changed. Answer should be B, previously was D. A load evaluator can look

at cpu context switches, but the default and advanced dont look at that. So you need to

create a custom load evaluator with cpu context switches enabled, and apply it to the 2

applications.

QUESTION: 44

Which policy should an administrator configure so that if all servers in a worker group go

offline, XenApp redirects user connections to a backup worker group?

A. Citrix User

B. Load Evaluator

C. Load Balancing

D. Citrix Computer

Answer: C

Explanation:

A load balencing policy can be used with worker groups

Scenario: An administrator plans to add printer drivers to the auto-replication list in a

XenApp 6.5 environment. The administrator needs to ensure that a specific vendor printer

driver is available on all servers in the farm including any new servers that are added at a

later date. How must the administrator add printer drivers to the auto-replication list?

A. Through a Citrix policy

B. With a PowerShell cmdlet

C. With the PrintCfg.exe tool

D. In a per-server registry setting

Answer: B

Explanation:

Auto-Replication List

1Y0-A20

Run the following cmdlet to add a print driver to the auto-replication list. Type Add-

XAAutoReplicatedPrinterDriver–DriverName “<name of driver>” –SourceServerName

XASource, where <name of driver> is the exact name of the print driver and XASource

is the source server and press Enter.

The output should be returned confirming the driver name, source server, and that we

do not wish to overwrite the driver if it exists (the default). This is the same output we

receive when running the Get- XAAutoReplicatedPrinterDriver cmdlet.

After waiting a moment, type Get-XAPrinterDriver –ServerName XADest, where

XADest is the name of a

XenApp server that did not originally contain the print driver that was just added to the

replication list.

If you should choose to remove a print driver from the auto-replication list, type

Remove- XAAutoReplicatedPrinterDriver –DriverName “<name of driver>” –

ServerName XASource, where <name of driver> is the exact name of the print driver and

XASource is a source server.

QUESTION: 46

Scenario: An administrator needs to use the session printers policy to provision network

printers from a 32-bit print server to XenApp users. Native Windows drivers are NOT

available to these printers. Which step should the administrator take prior to

implementing the session printers policy in this environment?

A. Configure the printer driver mapping and compatibility policy

B. Enable the automatic installation of in-box printer drivers policy

C. Install the corresponding 32-bit printer driver on the XenApp servers

D. Install the corresponding 64-bit printer driver on the XenApp servers

QUESTION: 47

Scenario: A company's Senior Citrix Administrator requested that an administrator

reconfigure the printing policies in a test XenApp 6.5 farm. The Citrix Universal Printer

Driver will be used exclusively and the number of auto-created printers on the server

should be kept to a minimum to conserve resources. Which two policies should the

administrator configure to meet these requirements? (Choose two.)

A. Disable the client printer redirection policy.

B. Enable the policy for the generic universal printer.

C. Enable the policy for the printing preview preference.

D. Configure the auto-create client printers policy so that client printers are NOT autocreated.

E. Configure the printer driver mapping and compatibility policy to map all drivers to the

Citrix Universal Printer Driver.

Answer: B, D

Explanation:

"exclusively" = E

"minimum to conserve resources" = D

QUESTION: 48

An administrator performs an installation of XenApp without changing any of the default

settings. When a user connects with a client printer that does NOT have a suitable driver

installed, but does have a suitable driver available in the driver store, which action will

happen?

A. The printer will be mapped using similar provided driver.

B. The printer will be mapped using the Citrix Universal Driver.

C. The driver will be installed and mapped using the newly installed driver.

D. The driver will be installed, and the printer will be mapped using the Citrix Universal

Driver.

Answer: C

Explanation:

During printer auto-creation, if XenApp detects a new local printer connected to a client

device, it checks the server hosting the published application (from which the user is

trying to print) for the required printer driver. By default, XenApp automatically installs a

native driver if one is not found on the server hosting the published application.

QUESTION: 49

Which two Citrix printing tools can assist a XenApp administrator when working with

printer drivers? (Choose two)

A. Print Migrator

B. Stress Printers

C. Print Detective

D. The Citrix Printing Tool

Answer: B, C

Explanation:

the Citrix Printing subsystem on XenApp, XenApp Online Plugin, and XenDesktop. Print

Detective: Print Detective is an information gathering utility that can be used for

troubleshooting problems related to print drivers. It enumerates all printer drivers from

the specified Windows machine, including driver specific information. It can also be used

to delete specified print drivers. It allows for log file capabilities and provides a

command-line interface as well. Stress Printers & Print Detective are the two tools that a

designed to work with drivers, so these should be the correct answers.

QUESTION: 50

Scenario: For users at remote offices, network printers are defined on their workstations.

A print server is located in each remote office. The WAN link speed to the datacenter

varies and the administrator would like to ensure the best possible printing performance

for these XenApp users. Which step should the administrator take to address the group of

users with minimal required effort?

A. Enable the session printers policy.

B. Disable the direct connections to print servers policy.

C. Reconfigure the network printers as local printers on the workstations.

D. Ensure that the vendor printer driver is installed on all XenApp servers in the farm.

Answer: B

Explanation:

Option A is invalid because the question already says the "network printers are defined

on their workstations" Option C is invalud because it says "minimal required effort"

Opton D is invalud because there's no problem with the drivers, the problem is with

bandwidth. Option B is correct. By default, XenApp routes jobs to network printers from

the application server directly to the print server (along the network printing pathway).

Note: Print jobs sent over the network printing pathway are not compressed. When

routing printing jobs across a network with limited bandwidth, Citrix recommends

routing jobs through the client device so that the ICA protocol compresses the jobs. To do

so, disable the Citrix policy setting Direct connection to print servers.
