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.

Based on the need to limit processing and bandwidth utilization due to dynamic routing protocol operation, the foll owing routing requirements have been specified for your network.
- partial and incremental routing updates
- only the devices affected by a topology change perform route recomputation
- route recomputation only occurs for routes that were affected
Which dynamic routing protocol should be deployed in your network to best meet these requirements?（）
A. BGP
B. OSPF
C. IS - IS
D. EIGRP
E. RIPv2
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.
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
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
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.
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?
A. the kind of OSPF areas being implemented
B. the number of external LSAs in the network
C. the number of DRs and BDRs in the areas
D. the number of virtual links in the areas
E. how well the areas can be summarized
F. the use of LSA filters
A. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinations
B. Have a backbo ne area (area 0) with 4 routers and 30,000 external routes injected into OSPF
C. Have less OSPF areas to reduce the need for interarea route summarizations
D. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2
You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds.
What could be the cause of this problem?（）
A. OSPF authentication errors between some of the routers
B. Two routers have the same OSPF router ID
C. Issues with mistuned OSPF timers
D. OSPF LSA pacing issues between some of the routers
E. OSPF neighbor adjacency problems between some of the routers
Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?（）
A. All OSPF implementations must have at le ast one interface in area 0.
B. You are attempting to run in the broadcast mode over an NBMA interface.
C. Both routers are configured to function as a BDR; therefore, there is no DR router.
D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.
E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.
