A router has learned three possible routes that could be used to reach a destination network. One route is from EIGRP and has a composite metric of 20514560. Another route is from OSPF with a metric of 782. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table?

Answer: B

The reason for regional structure division in OSPF network is: In a small network, the structure of router is not complicated, it is easy to identify routes to different destinations. However, in large What are two drawbacks of implementing a link-state routing protocol? (Choose two.)

The reason for regional structure division in OSPF network is: In a small network, the structure of router is not complicated, it is easy to identify routes to different destinations. However, in large What are two drawbacks of implementing a link-state routing protocol? (Choose two.)

B. the large size of the topology table listing all advertised routes in the converged network
C. the sequencing and acknowledgment of link-state packets
D. the high demand on router resources to run the link-state routing algorithm
E. the requirement for a hierarchical IP addressing scheme for optimal functionality



Answer: D,E

A router learns about a remote network from EIGRP, OSPF, and a static route. Assuming all routing protocols are using their default administrative distance, which route will the router use to forward data to the remote network?

Why is flash memory erased prior to upgrading the IOS image from the TFTP server?

Why is flash memory erased prior to upgrading the IOS image from the TFTP server?
