HPE Aruba Certified Mobility Professional (ACMP) — Question 16

Network administrators decide to change OSPF Area 1 to a stub area in order to solve some performance issues. No routes are redistributed into area 1.
What is one implication of making this change?

Answer options

• A. Endpoints in area 1 will no longer be able to reach external networks.
• B. Routing devices in area 1 will no longer exchange Type 1 and Type 2 LSAs with each other.
• C. Endpoints in area 1 will no longer be able to reach endpoints in other areas.
• D. Routing devices in area 1 will temporarily lose adjacency while the change is made.

Correct answer: A

Explanation

The correct answer is A because configuring Area 1 as a stub area prevents it from receiving external routes, limiting its access to external networks. Option B is incorrect since stub areas do not exchange Type 1 and Type 2 LSAs, but they still can communicate internally. Option C is wrong as endpoints within area 1 can still reach other areas; they just can't reach external networks. Option D is also incorrect because while changes may temporarily affect adjacency, it does not imply a permanent loss of connectivity.
