A network design shows area 1 with three internal routers, area 0 with four internal routers,
and area 2 with five internal routers. Additionally, one ABR (ABR1) connects areas 0 and 1,
plus a different ABR (ABR2) connects areas 0 and 2. How many Type 1 LSAs would be
listed in ABR2’s LSDB?

A network planning diagram shows a large internetwork with many routers. The
configurations show that OSPF has been enabled on all interfaces, IP addresses correctly
configured, and OSPF workinG. For which of the following cases would you expect a router
to create and flood a Type 2 LSA?

A verification plan shows a network diagram with branch office Routers B1 through B100,
plus two ABRs, ABR1, and ABR2, all in area 100. The branches connect to the ABRs using
Frame Relay point-to-point subinterfaces. The verification plan lists the output of the show ip
ospf database summary 10.100.0.0 command on a router B1, one of the branches. Which of
the following is true regarding the output that could be listed for this command?

Which of the following OSPF messages contains entire complete LSAs used during the
database exchange process?

Routers R1, R2, R3, and R4 connect to the same 10.10.10.0/24 LAN-based subnet.
OSPF is fully working in the subnet. Later, R5, whose OSPF priority is higher than the other
four routers, joins the subnet. Which of the following are true about the OSPF database
exchange process over this subnet at this point? (Choose two.)

R1 is internal to area 1, and R2 is internal to area 2. Subnet 10.1.1.0/24 exists in area 2 as
a connected subnet off R2. ABR ABR1 connects area 1 to backbone area 0, and ABR2
connects area 0 to area 2. Which of the following LSAs must R1 use when calculating R1’s
best route for 10.1.1.0/24?

Which of the following LSA types describes topology information that, when changed,
requires a router in the same area to perform an SPF calculation? (Choose two.)

The following output was taken from Router R3. A scan of R3’s configuration shows that no
bandwidth commands have been configured in this router. Which of the following answers
lists configuration settings could be a part of a configuration that results in the following
output? (Choose two.)
R3#show ip ospf interface brief
Interface PID Area IP Address/Mask Cost State Nbrs F/C
Se0/0/0.2 3 34 10.10.23.3/29 647 P2P 1/1

Fa0/0 3 34 10.10.34.3/24 20 BDR 1/1

Which of the following LSA types describe information related to topology or subnets useful
for calculating routes for subnets inside the OSPF domain? (Choose threE.)

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
