Review Questions EIGRP y OSPF

A. Neighbor table
B. STP table
C. Topology table
D. DUAL table

3. Which of the following describe the process identifier that is used to run OSPF on a router?
(Choose two.)
A. It is locally significant.
B. It is globally significant.
C. It is needed to identify a unique instance of an OSPF database.
D. It is an optional parameter required only if multiple OSPF processes are running on the router.
E. All routes in the same OSPF area must have the same Process ID if they are to exchange routing information.

4. Where are EIGRP successor routes stored?
A. In the routing table only
B. In the neighbor table only
C. In the topology table only
D. In the routing table and neighbor table
E. In the routing table and the topology table
F. In the topology table and the neighbor table

5. Which command will display all the EIGRP feasible successor routes known to a router?
A. show ip routes *
B. show ip eigrp summary
C. show ip eigrp topology
D. show ip eigrp adjacencies
E. show ip eigrp neighbors detail

6. 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 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.

7. Which of the following protocols support VLSM, summarization, and discontiguous networking?
(Choose three.)
A. RIPv1
F. RIPv2

8. Which of the following are true regarding OSPF areas? (Choose three.)
A. You must have separate loopback interfaces configured in each area.
B. The numbers you can assign an area go up to 65,535.
C. The backbone area is also called area 0.
D. If your design is hierarchical, then you don’t need multiple areas.
E. All areas must connect to area 0.
F. If you have only one area, it must be called area 1.

9. Which of the following network types have a designated router and a backup designated router assigned? (Choose two.)
A. Broadcast
B. Point-to-point
D. NBMA point-to-point
E. NBMA point-to-multipoint

10. A network administrator needs to configure a router with a distance-vector protocol that allows classless routing. Which of the following satisfies those requirements?
C. RIPv1

11. 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

12. For some reason, you cannot establish an adjacency relationship on a common Ethernet link between two routers. Looking at the output below, what is the cause of the problem?
Ethernet0/0 is up, line protocol is up
Internet Address, Area 0
Process ID 2, Router ID, Network Type BROADCAST, Cost: 10
Transmit Delay is 1 sec, State DR, Priority 1
Designated Router (ID), interface address
No backup designated router on this network Timer intervals configured, Hello 5, Dead 20, Wait 20, Retransmit 5
Ethernet0/0 is up, line protocol is up
Internet Address, Area 0
Process ID 2, Router ID, Network Type BROADCAST, Cost: 10
Transmit Delay is 1 sec, State DR, Priority 1
Designated Router (ID), interface address
No backup designated router on this network
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5

A. The OSPF area is not configured properly.
B. The priority on RouterA should be set higher.
C. The cost on RouterA should be set higher.
D. The Hello and Dead timers are not configured properly.
E. A backup designated router needs to be added to the network.
F. The OSPF Process ID numbers must match.

13. Which is true regarding EIGRP successor routes? (Choose two.)
A. A successor route is used by EIGRP to forward traffic to a destination.
B. Successor routes are saved in the topology table to be used if the primary route fails.
C. Successor routes are flagged as “active” in the routing table.
D. A successor route may be backed up by a feasible successor route.
E. Successor routes are stored in the neighbor table following the discovery process.

14. Which type of OSPF network will elect a backup designated router? (Choose two.)
A. Broadcast multi-access
B. Non-broadcast multi-access
C. Point-to-point
D. Broadcast multipoint

15. Which two of the following commands will place network into area 0? (Choose two.)
A. router eigrp 10
B. router ospf 10
C. router rip
D. network
E. network area 0
F. network area0
G. network area 0

16. With which network type will OSPF establish router adjacencies but not perform the DR/BDR
election process?
A. Point-to-point
B. Backbone area 0
C. Broadcast multi-access
D. Non-broadcast multi-access

17. What are three reasons for creating OSPF in a hierarchical design? (Choose three.)
A. To decrease routing overhead
B. To speed up convergence
