The OSPF hello timer has been set to 15 seconds on a router in a point-to-point network. By default, what is the dead interval on this router?

60 seconds

Which statement is correct about multiarea OSPF?

Arranging routers into areas partitions a large autonomous system in order to lighten the load on routers.

Which statement describes a difference or similarity between OSPFv2 and OSPFv3?

Both OSPFv2 and OSPFv3 use multicast destination addresses for link-state packets.

At which OSPF state are neighbor routers converged and able to exchange routing updates?

Full

Which two statements are correct about the OSPF passive-interface command? (Choose two.)

The OSPF network will benefit from more efficient use of bandwidth and resources. The router will not establish any OSPF neighbor relationships with routers on that link.

A network administrator configures a loopback interface as the OSPF router ID with the IP address of 192.168.1.1/30. What could be the consequence of using this 30-bit mask for the loopback interface?

This loopback interface may be advertised as a reachable network.

What will an OSPF router prefer to use first as a router ID?

any IP address that is configured using the router-id command

The command clear ip ospf __________ forces a router with a new or changed router ID to form new adjacencies.

process

A network technician issues the following commands when configuring a router: R1(config)# router ospf 11 R1(config-router)# network 10.10.10.0 0.0.0.255 area 0 What does the number 11 represent?

the OSPF process ID on R1

What are three entries that are displayed by the show ip ospf neighbor command? (Choose three.)

the router ID of the neighboring routers the OSPF state of each interface the IP address of the neighbor router interface to which this router is directly connected
