Cisco Securing Cisco Networks with Sourcefire Intrusion Prevention System Set 4

A router has two paths to reach another network in a different autonomous system. Neither route was generated by the local router and both routes have the same default weight and local preference values. Which statement is true about how BGP would select the best path? Select the best response.

How is authentication handled with OSPFv3? Select the best response.

By default, which statement is correct regarding the redistribution of routes from other routing protocols into OSPF? Select the best response.

When implementing OSPFv3, which statement describes the configuration of OSPF areas? Select the best response.

Which statement is true about OSPF Network LSAs? Select the best response.

You have just completed an OSPF implementation. While executing your verification plan, you determine that R1 is not able to establish full OSPF adjacency with R2. The show ip ospf neighbor command output on R1 shows that R2 is stuck in the INIT state. What could be the cause of this problem? Select the best response.

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? Select the best response.

When verifying OSPF virtual link problems, which is an important item to check on the two transit OSPF routers? Select the best response.

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 configurations are correct for generating type 3 LSAs? Select the best response.

Based on the need to limit processing and bandwidth utilization due to dynamic routing protocol operation, the following 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? Select the best response.
