R1, an ABR between backbone area 0 and area 1, has intra-area routes in area 0 for
10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24. These routes have metrics of 21, 22, and 23,
respectively. An engineer then adds the area 0 range 10.1.0.0 255.255.0.0 command under
the OSPF process of R1. Which of the following is true? (Choose two.)

The following output exists on Router R1, a router internal to area 1. What can you
determine as true from the output of the show ip ospf database summary command?

Router R1, an ASBR connected to the Internet and to backbone area 0, has been configured
with a default-information originate command. Which of the following is true about the effects
of this configuration command?

Which of the following is true about routers internal to a totally NSSA area?
(Choose two.)

ABR R1 has been configured with an area 1 stub no-summary command. Which stubby area
type is area 1?

Which of the following answers can be verified as true based on the following command
output from Router R1?
R1#show ip ospf virtual-links

Several links have been broken so that for the next day or two, what was formerly a
contiguous area 0 has been broken into two parts. However, both parts of area 0 have
working links into area 1 using routers with RID 1.1.1.1 and 2.2.2.2. Which answers list the
command on the router with RID 1.1.1.1 to create a virtual link to help solve this temporary
problem?

Router R1 connects to a Frame Relay cloud using a multipoint subinterface, with ten
PVCs associated with the subinterface. What command would make this router not use a
DR and require static OSPF neighbor definition?

Router R1 connects to a Frame Relay cloud using a multipoint subinterface, with ten
PVCs associated with the subinterface. What command would make this router not use a
DR, and dynamically discover OSPF neighbors?

Ten routers, R1 through R10, connect in a partial mesh over Frame Relay. For the mesh, R1
and R2 have PVCs connected to all other routers, but Routers R3 through
R10 act as branch routers, with only two PVCs–one to R1 and one to R2. The routers use IP
subnet 10.1.1.0/24, with addresses 10.1.1.1, 10.1.1.2, and so on, through 10.1.1.10,
respectively. The routers all use Inverse ARP to learn Frame Relay mapping information. All
routers use a multipoint subinterface with network type point-tomultipoint nonbroadcast. A
co-worker’s implementation plan lists lots of configuration commands related to this design.
The design states that all hosts should be able to ping all other hosts. Which commands are
required for proper functioning of OSPF in this case? (Choose two.)
