B.        Router(config)#router ospf 0

C.        Router(config)#router ospf area 0

D.        Router(config-router)#network 192.168.16.0 0.0.0.255 area 0

E.         Router(config-router)#network 192.168.16.0 0.0.0.255 0

F.         Router(config-router)#network 192.168.16.0 255.255.255.0 area 0

 

Correct Answer: AD

 

 

QUESTION 222

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

 

 

QUESTION 223

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

 

clip_image002

 

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

B.       The router at 208.149.23.130 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

 

 

QUESTION 224

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?

B.       network 172.26.0.0

C.       network 172.26.168.128 0.0.0.127

D.       network 172.26.168.128 area 478

 

Correct Answer: B

Correct Answer: A

 

 

QUESTION 228

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

 

 

 

 

 

 

QUESTION 229

What is the default administrative distance of OSPF?

 

A.        120

B.        100

C.        90

D.        110

 

Correct Answer: D

 

 

QUESTION 230

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?

 

clip_image006

 

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 172.16.100.0, 172.16.100.28 and 172.16.100.64 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
