1.單項選擇題

Refer to the above exhibit. Why are the EIGRP neighbors for this router not learning the  routes redistributed from OSPF?()

A. Redistribution must be enabled mutually (in both directions) to work correctly.
B. auto - summary causes the OSPF routes redistributed into EIGRP to be summarized; thus the OSPF network 116.16.34 is summarized to 116.3 4.0.0, which is already covered by the EIGRP protocol.
C. Default metrics are not configured under EIGRP.
D. Both routing protocols must have unique autonomous system numbers for redistribution to function correctly.

2.單項選擇題

Refer to the above exhibit. Why is the 140.140.0.0 network not used as the gateway of last resort even though it is configured first?()

 

A.The last default - network statement will always be preferred.
B.A route to the 140.140.0.0 network does not exist in the routing table.
C.Default - network selection will always prefer the statement with the lowest  IP address.
D.A router will load balance across multiple default - networks; repeatedly issuing the show ip route command would show the gateway of last resort changing between the two networks.

3.單項選擇題Your network consists of a large hub - and - spoke Frame Relay network with a CIR of 56 kb/s foreach spoke. Which statement about the selection of a dynamic protocol is true?()

A. EIGRP would be appropriate if LMI type ANS I 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.

4.單項選擇題Which statement about a none zero value for the load metric (k2) for EIGRP is true?()

A. A change in the load on an interface will cause EIGRP to recalculate the routing metrics and send a corresponding update out to each of its neighbors.
B. EIGRP calculates interface load as a 5 - minute exponentially weighted average that is  updated every 5 minutes.
C. EIGRP considers the load of an interface only when sending an update for some other reason.
D. A change in the load on an interface will cause EIGRP to recalculate and update the administrative distance for all routes learne d on that interface.

6.單項選擇題Which condition must be satisfied before an EIGRP neighbor can be considered a feasiblesuccessor?()

A. The neighbor's advertised distance must be less than or equal to the feasible distance of the current successor.
B. The neighbor's advertised distance must be less than the f easible distance of the current successor.
C. The neighbor's advertised distance must be greater than the feasible distance of the current successor.
D. The neighbor's advertised distance must be equal to the feasible distance of the current successor .
E. The neighbor's advertised distance must be greater than or equal to the feasible distance of the current successor.

7.單項選擇題You are developing a verification plan for an upcoming OSPF implementation. Part of this plan is to verify the status of type 3 LSAs within the network. Which routers should you verify first to ensure that the configuration s are correct for generating type 3 LSAs?()

A. Internal routers within the backbone area (area 0)
B. Internal routers within the NSSAs
C. Internal routers within the stubby areas
D. ASBRs
E. ABRs
F. DRs and BDRs

8.單項選擇題When verifying OSPF virtual link problems, which is an important item to check on the two transit OSPF routers?()

A. OSPF process ID
B. OSPF router ID
C. OSPF network type
D. OSPF memory usage
E. OSPF CPU utilization
F. OSPF stub area configurations

9.多項選擇題When verifying the OSPF link state database, which type of LSAs should you expect to see within the different OS PF area types?()

A. All OSPF routers in stubby areas can have type 3 LSAs in their database.
B. All OSPF routers in stubby areas can have type 7 LSAs in their database.
C. All OSPF routers in totally stubby areas can have type 3 LSAs in  their database.
D. All OSPF routers in totally stubby areas can have type 7 LSAs in their database.
E. All OSPF routers in NSSA areas can have type 3 LSAs in their database.
F. All OSPF routers in NSSA areas can have type 7 LSAs in their database.

10.多項選擇題You are troubleshooting an OSPF problem where external routes are not showing up in the OSPF database. Which two options a re valid checks that should be performed first to verify proper OSPF operation?()

A. Are the ASBRs trying to redistribute the external routes into a totally stubby area?
B. Are the ABRs configured with stubby areas?
C. Is the subnets keyword being used with the redistribution command?
D. Is backbone area (area 0) contiguous?
E. Is the CPU utilization of the routers high?
