HPE Aruba Certified Network Security Expert (ACNSX) — Question 73

A network has an ABR that connects area 0 and 1. A network engineer configures a summarized route for area 0. The ABR is a designated router (DR) for the segment it uses to connect to area 1.
Which LSA type is assigned to this route when the summarized route is advertised into area 1 by the ABR?

Answer options

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

Correct answer: C

Explanation

The correct answer is LSA 3 because summarized routes are advertised by the ABR into other areas as type 3 LSAs. LSA 1 is for router LSAs, LSA 2 is for network LSAs, and LSA 4 is used for summarization to ASBRs, which do not apply in this scenario.
