The Dev-1 and Dev-3 routers are OSPF neighbors over the Ethernet 0/0 connection. Based
on the show ip ospf neighbor output from the Dev-1 and Dev-3 routers, which statement is
true?

Refer to the diagram. Which OSPF configuration command is required to configure Area 3
as a totally stubby area?

Which show command will display only the Type 5 LSAs in the OSPF topology database?

Which three are advantages to creating multiple areas in OSPF? (Choose three.) Select 3
response(s).

What are two Cisco IOS commands that can be used to view neighbor adjacencies?
(Choose two.)

DR (Designated Router) is for environments where many routers on the same network such
as Ethernet. In the following presented network, all routers are reloaded simultaneously, and
DR is selected as expected. What is the RTC status?

Refer to the exhibit. During the process of configuring a virtual link to connect area 2 with the
backbone area, the network administrator received this console message on R3:
*Mar 1 00:25:01.084: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from
backbone area must be virtual link but not found from 20.20.20.1, Serial 0
How should the virtual link be configured on the OSPF routers to establish full connectivity
between the areas?

OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are
active. However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip

ospf neighbor command executed on R2 shows the state of the neighbors. What should be
done to fix the problem?

Open Shortest Path First (OSPF) is a routing protocol developed for Internet Protocol (IP)
networks by the Interior Gateway Protocol (IGP) working group of the Internet Engineering
Task Force (IETF). Which two statements best describe the OSPF link-state routing
protocol? (Choose two.)

An administrator types in the command router ospf 1 and receives the error message:
“OSPF process 1 cannot start.” (Output is omitted.) What should be done to correctly set up
OSPF?
