HPE Aruba Certified Mobility Professional (ACMP) — Question 46

OSPF Area 1 has two ABRs. One ABR is configured with this range for Area 1: 10.10.0.0/16. The other ABR is not configured with a range for Area 1.
Which type of issue occurs due to this mismatch?

Answer options

• A. The ABRs create a discontinuous area and disrupt intra-area routing between devices within Area 1.
• B. The ABR core would send Area 1 traffic destined to the other switch through an access switch.
• C. The ABRs lose adjacency entirely and cannot route traffic between each other at all.
• D. The ABRs lose adjacency in Area 1 and must route all traffic to each other through Area 0.

Correct answer: A

Explanation

The correct answer is A because having two ABRs with mismatched configurations can lead to a discontinuous area, which disrupts intra-area routing. Options B, C, and D do not accurately describe the impact of the configuration issue, as they do not reflect the specific problem caused by the lack of a defined range on one of the ABRs.
