True or false: A router with an interface associated with Area 1 and Area 2 will be able to inject routes learned from one area into another area.

• True

• False

True or false: A member router contains a complete copy of the LSDBs for every area in the routing domain.

• True

• False

How many OSPF link-state advertisement (LSA) types are used for routing traditional IPv4 packets?

• Two

• Three

• Five

• Six

• Seven

What is the LSA age field in the LSDB used for?

• For version control—to ensure that the most recent LSA is present

• To age out old LSAs by removing an LSA when its age reaches zero

• For troubleshooting—to identify exactly when the LSA was advertised

• To age out old LSAs by removing an LSA when it reaches 3600 seconds

Which LSA type exists in all OSPF areas?

• Network

• Summary

• Router

• AS external

True or false: When an ABR receives a network LSA, the ABR forwards the network LSA to the other connected areas.

• True

• False

When a type 3 LSA is received in a non-backbone area, what does the ABR do?

• Discards the type 3 LSA and does not process it

• Installs the type 3 LSA for only the area where it was received

• Advertises the type 3 LSA to the backbone area and displays an error

• Advertises the type 3 LSA to the backbone area

True or false: OSPF uses the shortest total path metric to identify the best path for every internal OSPF route (intra-area and inter-area).

• True

• False

True or false: Breaking a large OSPF topology into smaller OSPF areas can be considered a form of summarization.

• True

• False

How is the process of summarizing internal routes on an OSPF router accomplished?

• By using the interface configuration command summary-address network prefix-length

• By using the OSPF process configuration command summary-address network prefix-length

• By using the OSPF process configuration command area area-id range network subnet-mask

• By using the interface configuration command area area-id summary-address network subnet-mask
