Dell EMC Specialist – Systems Administrator, VNX — Question 42

Which LSA type provides information necessary to reach routers originating type 5 LSA's in other areas?

Answer options

• A. ASBR-Summary (Type 4)
• B. Summary (Type 3)
• C. NSSA (Type 7)
• D. Router (Type 1)

Correct answer: A

Explanation

The correct answer is A, ASBR-Summary (Type 4), as it specifically contains information required to locate ASBRs that create type 5 LSAs in other OSPF areas. The other options do not provide this necessary routing information: Type 3 LSAs summarize networks within the same area, Type 1 LSAs describe routers within the same area, and Type 7 LSAs are used for NSSA but do not aid in reaching type 5 LSAs.
