Exercise: Eigrp And Ospf

Questions for: Eigrp And Ospf

You need the IP address of the devices with which the router has established an adjacency. Also, the retransmit interval and the queue counts for the adjacent routers need to be checked. What command will display the required information?
A:
show ip eigrp adjacency
B:
show ip eigrp topology
C:
show ip eigrp interfaces
D:
show ip eigrp neighbors
Answer: D
The show ip eigrp neighbors command allows you to check the IP addresses as well as the retransmit interval and queue counts for the neighbors that have established an adjacency.

Which type of OSPF network will elect a backup designated router?
  1. Broadcast multi-access
  2. Non-broadcast multi-access
  3. Point-to-point
  4. Broadcast multipoint
A:
1 and 2
B:
3 and 4
C:
3 only
D:
None of the above
Answer: A
DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-broadcast multi-access (NBMA) network by default. No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology.

You get a call from a network administrator who tells you that he typed the following into his router: 
Router(config)#router ospf 1
Router(config-router)#network 10.0.0.0 255.0.0.0 area 0
He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?
A:
The wildcard mask is incorrect.
B:
The OSPF area is wrong.
C:
The OSPF Process ID is incorrect.
D:
The AS configuration is wrong.
Answer: A
The administrator typed in the wrong wildcard mask configuration. The wildcard should have been 0.0.0.255.

Which of the following protocols support VLSM, summarization, and discontiguous networking?
  1. RIPv1
  2. IGRP
  3. EIGRP
  4. OSPF
  5. BGP
  6. RIPv2
A:
1 and 4
B:
2 and 5
C:
3, 4 and 6
D:
All of the above
Answer: C
RIPv1 and IGRP are true distance-vector routing protocols and can't do much, really-except build and maintain routing tables and use a lot of bandwidth! RIPv2, EIGRP, and OSPF build and maintain routing tables, but they also provide classless routing, which allows for VLSM, summarization, and discontiguous networking.
