Why does a router create an ASBRSum (Type 4) LSA?

For two OSPF neighbors to establish a full adjacency on a broadcast medium, what information in
their hello packets must match? (Choose two.)

In the exhibit, Area 2.2.2.2 is configured as a not-so-stubby area and Area 1.1.1.1 is configured as
a normal area. R5 has an export policy that causes the RIP network prefixes to be announced
through OSPF. Which LSA type does R7 receive describing the RIP network prefixes?

What is preserved by enabling graceful Routing Engine switchover (GRES)?

In the exhibit, Areas 1.1.1.1 and 2.2.2.2 are configured as normal areas. R5 has an export policy
that causes the RIP network prefixes to be announced through OSPF. Which three LSA types
does R7 receive for the information advertised by R5? (Choose three.)

In the exhibit, Areas 1.1.1.1 and 2.2.2.2 are configured as normal areas. In R7’s OSPF
configuration, the interface on the 172.30.1.0/24 network is configured with the passive option. In
which LSA type does R5 receive the announcement for the 172.30.1.0/24 network?

You configure a network according to the topology shown in the exhibit but find that users
attached to R7 are having difficulty communicating with the rest of the network. What are two
solutions to the problem? (Choose two.)

In the exhibit, R5 is exporting the RIP network prefixes into OSPF. You want to limit the number of
LSAs sent to Area 2.2.2.2, but you want to ensure that all routers in other are as will have routes
to all networks contained in the LSAs sent by the routers in Area 2.2.2.2. Which configuration
change will enable this scenario?

You attach six routers (R1, R2, R3, R4, R5, and R6) to a single Ethernet LAN and configure the
routers with addresses in the same subnet. You do not modify the default priority of any router. R1
is chosen as the designated router and R2 is chosen as the backup designated router. How many
full adjacencies does R3 have?

In the exhibit, four routers (R1, R2, R3, and R4) are attached to a single Ethernet LAN and
configured with addresses in the same subnet. All devices boot at the same time. Which router or
routers will send a Network (Type 2) LSA for the network?
