Demo Questions

Question 1
Two routers are physically connected running ISIS. ISIS L2 adjacency is up and running but L1 adjacency is not up. Review the configuration information shown below: Which of the following statement best describe the cause of the problem? Select one answer only. 
  
  1. The ISIS interface level is not configured on both routers
  2. The ISIS interface type should be configured as point-to-point interfaces
  3. ISIS System IDs are not configured on both routers
  4. ISIS Area addresses are not configured on both routers
  5. ISIS level capacity are not configured on both routers
Correct answer: D
Question 2
L1 ISIS adjacency is up between two routers (Node-1 and Node-2) with MD5 authentication configured. During a maintenance window, an operator was planning to change one of the ISIS hello authentication key from admin to admin123. After removing the hello authentication key from Node-1 (no change on Node-2 side), the ISIS adjacency stayed up. The operator decided to fall back to the original configuration and called Alcatel for support. Which of the following statement best describe the cause of the problem? Select one answer only.  
  
  1. The ISIS hello authentication key was not configured properly in the first place, that's why removing the authentication key does not impact the adjacency
  2. The ISIS authentication key is the same as the hello authentication key, therefore removing hello authentication key does not impact the adjacency
  3. The system interface is missing from the ISIS configuration, therefore ISIS is not working properly even before the change
  4. ISIS hello authentication key is only used for hello packet exchange. It does not affect ISIS adjacency
  5. ISIS hello authentication key is not used to bring up ISIS adjacency when traffic-engineering is enabled on the routers
Correct answer: B
Question 3
What are the typical RIP related issues found during troubleshooting?
  1. Interface filters
  2. Broadcast/Multicast mismatch

  2. Redistribute interface address Y and Z into BGP
  3. ISIS Enable route-reflection on Node B
