Q51. Which two routing protocols require a metric to be configured when redistributing routes from other protocols? (Choose two.)

A. RIP

B. BGP

C. IS-IS

D. OSPF

E. EIGRP

Answer: AE


Q52. An administrator types in the command router ospf 1 and receives the error message:

"OSPF process 1 cannot start." (Output is omitted.) What should be done to correctly set up OSPF? Select the best response.

A. Ensure that an interface has been configured with an IP address.

B. Ensure that an interface has been configured with an IP address and is up.

C. Ensure that IP classless is enabled.

D. Ensure that the interfaces can ping their directly connected neighbors.

Answer: B

What can you conclude about this network?

Select the best response.

B. The network has been stable for at least the last 45 minutes.

C. There is a flapping link or interface, and router C knows an alternate path to the network.

D. There is a flapping link or interface, and router A does not know an alternate path to the network.

E. EIGRP is not working correctly on router C.

F. There is not enough information to make a determination.

Answer: A


Q54. Your network consists of a large hub-and-spoke Frame Relay network with a CIR of 56 kb/s for each spoke. Which statement about the selection of a dynamic protocol is true?

Select the best response.

A. EIGRP would be appropriate if LMI type ANSI is NOT used.

B. EIGRP would be appropriate, because the Frame Relay spokes could be segmented into their own areas.

C. EIGRP would be appropriate, because by default, queries are not propagated across the slow speed Frame Relay links.

D. EIGRP would be appropriate, because you can manage how much bandwidth is consumed over the Frame Relay interface.

Answer: D


Q55. Your network has a mixture of Fast Ethernet and Gigabit Ethernet links. What needs to be done to ensure optimal data routing when using OSPF?

A. Nothing. OSPF will determine the most optimal path for routing data by default.

B. Adjust the hello and dead timers for more rapid detection of link failures.

C. Increase the reference-bandwidth used to calculate the interface default metrics, on all routers in your network.

D. Set the priority values on every broadcast interface to ensure that the designated and backup designated routers are the routers with the most processor and memory resources.

Answer: C


Updated 642-902 route dumps:

Q56. Refer to the exhibit. EIGRP has been configured on routers R1 and R2. However, R1 does not show R2 as a neighbor and does not accept routing updates from R2. What could be the cause of the problem?

A. The no auto-summary command has not been issued under the EIGRP process on both routers.

B. Interface E0 on router R1 has not been configured with a secondary IP address of 10.1.2.1/24.

C. EIGRP cannot exchange routing updates with a neighbor's router interface that is configured with two IP addresses.

D. EIGRP cannot form neighbor relationship and exchange routing updates with a secondary address.

Answer: D


Q57. Refer to the exhibit.

On the basis of the configuration that is provided, how would the BGP updates that come from router R1 be replicated inside autonomous system 65200?

A. All BGP updates that are received on router R2 will be sent to routers R3 and R4. Routers R3 and R4 will then forward those BGP updates to router R5.

B. All BGP updates that are received on router R2 will not be sent to routers R3 and R4.

C. All BGP updates that are received on router R2 will be sent directly to router R5.

D. None of the BGP updates that are received on router R2 will ever be received by router R5.

Answer: D


Q58. When a primary route fails, what will be used? (EIGRP)

Select the best response.

A. Administrative distance

B. Successor

C. (kind of weired name of successor that i didn”t recognize)

D. Feasible Successor

Answer: D


Q59. Which three statements are true about EIGRP route summarization? (Choose three.)

A. Manual route summarization is configured in router configuration mode when the router is configured for EIGRP routing.

B. Manual route summarization is configured on the interface.

C. When manual summarization is configured, the summary route will use the metric of the largest specific metric of the summary routes.

D. The ip summary-address eigrp command generates a default route with an administrative distance of 90.

E. The ip summary-address eigrp command generates a default route with an administrative distance of 5.

F. When manual summarization is configured, the router immediately creates a route that points to null0 interface.

Answer: BCF


Q60. R1 and R2 are connected and are running EIGRP on all their interfaces, 

R1 has four interfaces，with IP address 172.16.1.1/24, 172.16.2.3/24, 172.16.5.1/24, and 10.1.1.1/24. 

R2 has two interfaces, with IP address 172.16.1.2/24 and 192.168.1.1/24. 

There are other routers in the network that are connected on each of the interfaces of these two routers that are also running EIGRP. 

Which summary routes does R1 generate automatically (assuming auto-summarization is enable)? (choose two.)

Select the 2 best responses.

A. 192.168.1.0/24

B. 10.0.0.0/8

C. 172.16.1.0/22

D. 172.16.0.0/16

E. 10.1.1.0/24
