Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 362

Which two OSPF area types filter type 4 and type 5 LSAs? (Choose two.)

Answer options

• A. Level 2
• B. not-so-stubby
• C. totally stubby
• D. level 1
• E. stub
• F. Level1 "" Level2

Correct answer: C, E

Explanation

The correct answers are C and E because a totally stubby area does not allow type 4 and type 5 LSAs, effectively filtering them out. A stub area also restricts the propagation of these LSAs, whereas other area types like Level 2 and not-so-stubby still permit these LSAs to be exchanged.
