CCNP Job Interview Questions & Answere Part 3   Q201: Does IS-IS elect a Backup Designated Router on a broadcast subnetwork?   Ans: IS-IS does not elect a BDR.   Q202: What is the purpose of the Pseudonode ID?   Ans: The Pseudonode ID is the last octet of a LAN ID. Its purpose is to distinguish LAN IDs which are originated by a single router which is the DR on multiple LANs.   Q203: What is the maximum age (MaxAge) of an IS-IS LSP?   Ans: The MaxAge of an IS-IS LSP is 1200 seconds (20 minutes).

CCNP Job Interview Questions & Answere Part 2   Q101: What is a recursive table lookup?   Ans: A recursive routing table lookup occurs when a router cannot acquire all the information it needs to forward a packet with a single routing table lookup. For example, the router may perform one lookup to find the route to a destination and then perform another lookup to find a route to the next hop router of the first route.   Q102: What is a routing protocol?   Ans: A routing protocol is a "language" that routers speak to each other to share information about        network destinations.   Q103: What basic procedures should a routing algorithm perform?   Ans: At a minimum, a routing protocol should define procedures for        Passing reachability information about networks to other routers        Receiving reachability information from other routers       ...

CCNP Job Interview Questions & Answere Part 1 Q1. What are three types of LAN traffic? Ans. Unicasts - intended for one host. Broadcasts - intended for everyone. Multicasts - intended for a only a subset or group within an entire network. Q2. What are unicast frames? Ans. Unicast frames are the most common type of network traffic. A unicast frame is a frame intended for only one host. The only station that processes this frame is one station that has its own MAC address in the destination portion of packet. Q3. How do you enable IGRP on a Cisco router? Ans. The way you enable IGRP on a Cisco router is similar to the way you enable RIP, except you specify IGRP as the protocol and add an autonomous system number. For example: RouterA(config)# router igrp 10 (10 is the AS number) RouterA(config-router)# network 192.168.0.0 RouterA(config-router)# network 192.168.1.0 RouterA(config-router)# network 192.168.2.0

The data unit created at the application layer is called a message, at the transport layer the data unit created is called either a segment or an user datagram, at the network layer the data unit created is called the datagram, at the data link layer the datagram is encapsulated in to a frame and finally transmitted as signals along the transmission media. Q52. What is Project 802? Ans. It is a project started by IEEE to set standards that enable intercommunication between equipment from a variety of manufacturers. It is a way for specifying functions of the physical layer, the data link layer and to some extent the network layer to allow for interconnectivity of major LAN protocols. It consists of the following: 802.1 is an internetworking standard for compatibility of different LANs and MANs across protocols. 802.2 Logical link...

Ans. 10Base2—An Ethernet term meaning a maximum transfer rate of 10 Megabits per second that uses baseband signaling, with a contiguous cable segment length of 100 meters and a maximum of 2 segments. 10Base5—An Ethernet term meaning a maximum transfer rate of 10 Megabits per second that uses baseband signaling, with 5 continuous segments not exceeding 100 meters per segment. 10BaseT—An Ethernet term meaning a maximum transfer rate of 10 Megabits per second that uses baseband signaling and twisted pair cabling. Q2. What is the difference between an unspecified passive open and a fully specified passive open? Ans. An unspecified passive open has the server waiting for a connection request from a client. A fully specified passive open has the server waiting for a connection from a specific client. Q3. Explain the function of Transmission Control Block. Ans....

Interview Questions for Network Support Technician Q. Please describe the importance you place on customer service versus technical skills. A. Most interviewers like to start with big picture questions and then work their way into more technical areas. IT is a service organization and customer service is at its core. In particular, customer service skills are just as important as technical skills, particularly in panic situations when systems are down or the user has just deleted their board presentation that’s due in 30 minutes. We’ve all had these situations. You should be prepared to talk about a specific situation where you’ve excelled and received accolades from an end-user. If they put it in writing, mention that as well. Q. What steps do you take when troubleshooting a networking issue? A. As a support technician, your job is to solve problems. This question provides the interviewer with insight into your troubleshooting skills. Of course, the most important part of troub...

Interview Questions for System Engineer / Network Engineer General Questions Q. Describe the network environments of the organizations that you have supported in the past. A. This general question provides you with an opportunity to start the conversation regarding the technologies that you have experience with. Be descriptive in your answer. Include the number of users, number of remote sites, types of systems, type of connectivity between sites, network configuration, ISP used, routers/switches used, and the size of the overall engineering team. Also include who you reported to and the management style of that manager. Q. What’s the difference between the WWW and the Internet? A. This question will throw a lot of people off, but it is absolutely valid. The Internet is a collection of computers and networks that can all talk to each other, while WWW is an application that runs on the Internet. Q. What is TCP/IP? A. This is a great question in that it forces the candidate to...
