HPE Aruba Certified Network Security Expert (ACNSX) — Question 15

An administrator has an aggregation layer of 8325CX switches configured as a VSX pair. The administrator is concerned that when OSPF network changes occur, the aggregation switches will respond to the changes slowly, and this will affect network connectivity, especially VoIP calls, in the connected access layer switches.
What should the administrator do on the aggregation layer switches to alleviate this issue?

Answer options

• A. Implement route aggregation
• B. Implement bidirectional forwarding detection (BFD)
• C. Reduce the hello and dead interval timers
• D. Implement graceful restart

Correct answer: A

Explanation

The correct answer is A, as implementing route aggregation can reduce the number of OSPF route changes that need to be processed, thus speeding up convergence times. Options B and C focus on improving OSPF detection and interval settings, which may not directly address the root issue of slow responses due to frequent changes. Option D, while useful in other contexts, does not specifically help with the issue of slow OSPF convergence related to network changes.
