Router B1, an internal router in area 1, displays the following output. The only two
ABRs connected to area 1 are performing Type 3 LSA filterinG. Which of the following
answers is true based on the information in the output from B1?
R1# show ip route 10.1.0.0 255.255.0.0 longer-prefixes

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

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
Virtual Link OSPF_VL0 to router 4.4.4.4 is up

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?
