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-

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

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.

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.

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.

* 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

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?

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.

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.

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:

A and D do not troubleshoot a printer driver Print Migrator (Windows tool) Print
Migrator provides complete backup, restore and migration operations for Windows NTbased
operating systems from Windows NT 4 to Windows 2003. Stress Printer Tool This
tool can be used to simulate multiple sessions autocreating printers using the same printer
driver.Citrix Printing Tool Citrix Printing Tool 3.1 helps configuring and troubleshooting
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.

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.
