Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 41

In OSPF, which LSA type is responsible for pointing to the ASBR router?

Answer options

• A. type 1
• B. type 2
• C. type 3
• D. type 4

Correct answer: D

Explanation

The correct answer is D, as Type 4 LSAs are specifically used to indicate the presence of ASBR routers in OSPF. Type 1 LSAs are for router links, Type 2 LSAs represent network links, and Type 3 LSAs describe summary routes, none of which point to ASBRs.
