Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 296

When verifying the OSPF link state database, which type of LSAs should you expect to see within the different OSPF area types? (Choose three.)

Answer options

• A. All OSPF routers in stubby areas can have type 3 LSAs in their database.
• B. All OSPF routers in stubby areas can have type 7 LSAs in their database.
• C. All OSPF routers in totally stubby areas can have type 3 LSAs in their database.
• D. All OSPF routers in totally stubby areas can have type 7 LSAs in their database.
• E. All OSPF routers in NSSA areas can have type 3 LSAs in their database.

Correct answer: O, S, P, F, N, S, S, A

Explanation

The correct answers are A, B, and E because stub areas can contain type 3 LSAs and NSSA areas can contain type 3 LSAs as well. However, totally stubby areas do not allow type 3 or type 7 LSAs, which makes options C and D incorrect.
