Q

Which three statements describe features of the OSPF topology table?

A
  1. When converged, all routers in an area have identical topology tables.
  2. It is a link-state database that represents the network topology.
  3. The table can be viewed via the show ip ospf database command.

18
Q

What is the first precedence for making a router ID on an OSPF enabled router?

19
Q

What is the second precedence for making a router ID on an OSPF enabled router?

A

Loopback interface IP address 172.16.1.1

21
Q

To quickly verify OSPFv3 configuration information including the OSPF process ID, the router ID, and the interfaces enabled for OSPFv3, you need to issue the command

A

show ipv6 protocols

22
Q

A router is participating in an OPSFv2 domain. What will always happen if the dead interval expires before the router receives a hello packet from an adjacent DROTHER OPSF router?

A

OSPF will remove that neighbor from the router link-state database.

24
Q

Which OSPF component is identical in all routers in an OSPF area after convergence?

A

Link-state database

25
Q

What is a function of OSPF hello packets?

A

To discover neighbors and build adjacencies between them

26
Q

A network administrator enters the command ipv6 router ospf 64 in global configuration mode. What is the result of this command?

A

The OSPFv3 process will be assigned an ID of 64.

27
Q

Which OSPFv3 function works differently from OSPFv2?

A

authentication

29
Q

Which OPSF packet contains the different types of link-state advertisements?

A

LSU

30
Q

When a network engineer is configuring OSPFv3 on a router, which command would the engineer issue immediately before configuring the router ID?

A

ipv6 router ospf 10

31
Q

What is the fourth precedence for making a router ID on an OSPF enabled router?

A

Serial interface IP address 192.168.10.1

32
Q

Which command will verify that a router that is running OSPFv3 has formed an adjacency with other routers in its OSPF area?

A

show ipv6 ospf neighbor

33
Q

This is where you can find the topology table.

A

link-state database
