Which commands are required to properly configure a router to run OSPF and to add network to OSPF area 0? (Choose two)


A.        Router(config)#router ospf 1

B.        Router(config)#router ospf 0

C.        Router(config)#router ospf area 0

D.        Router(config-router)#network area 0

E.         Router(config-router)#network 0

F.         Router(config-router)#network area 0


Correct Answer: AD




Which parameter or parameters are used to calculate OSPF cost in Cisco routers?


A.  Bandwidth, Delay, and MTU

B.  Bandwidth

C.  Bandwidth and MTU

D.  Bandwidth, MTU, Reliability, Delay, and Load


Correct Answer: B




Refer to the exhibit. Why are two OSPF designated routers designated routers identified on Core-Router?




A.       Core-Router is connected more than one multi-access network.

B.       The router at is a secondary DR in case the primary fails.

C.       Two router IDs have the same OSPF priority and are therefore tied for DR election.

D.       The DR election is still underway and there are two contenders for the role.


Correct Answer: A




The EIGRP configuration in the Glencoe router uses a single network statement. From the output shown in the graph would advertise these networks in EIGRP?




A.       network area 478

B.       network

C.       network

D.       network area 478


Correct Answer: B




Which type of EIGRP route entry describes a feasible successor?


A.       a primary route, stored in the routing table

B.       a backup route, stored in the routing table

C.       a backup route, stored in the topology table

D.       a primary route, stored in the topology table


Correct Answer: C




What is the default maximum number of equal-cost paths that can be placed into the routing of a cisco OSPF router?


A.     16

B.     2

C.     unlimited

D.     4


Correct Answer: D




Router 1 was just successfully rebooted. Identify the current OSPF router ID for Router 1.









Correct Answer: A




Why do large OSPF networks use a hierarchical design? (Choose three)


A.        to confine network instability to single areas of the network

B.        to reduce the complexity of router configuration

C.        to speed up convergence

D.        to lower costs by replacing routers with distribution layer switches

E.         to decrease latency by increasing bandwidth

F.         to reduce routing overhead


Correct Answer: ACF








What is the default administrative distance of OSPF?


A.     120

B.     100

C.     90

D.     110


Correct Answer: D




Part of the OSPF network is shown below. You work as a network technician, study the exhibits carefully. Assume that all router interfaces are operational and correctly configured. In addition, assume that OSPF has been correctly configured on router R2. How will the default route configured on R1 affect the operation of R2?




A.        Any packet destined for a network that is not directly connected to router R2 will be dropped immediately

B.        Any packet destined for a network that is not directly connected to router R1 will be dropped

C.        Any packet destined for a network that is not directly connected to router R2 will be dropped immediately because of the lack of a gateway on R1

D.        The network directly connected to a router R2 will not be able to communicate with the, and subnetworks.

E.         Any packet destined for a network that is not referenced in the routing table of router R2 will be directed to R1. R1 will then send that packet back to R2 and a routing loop will occur


Correct Answer: E
