Designing Cisco Network Service Architectures (ARCH, legacy) — Question 58

An engineer is working on an OSPF network design and wants to minimize the failure detection time and the impact on the router CPU. Which technology accomplishes this goal?

Answer options

Correct answer: C

Explanation

The correct answer is C, LSA pacing, which helps to control the frequency of Link-State Advertisements (LSAs) in OSPF, thereby reducing CPU load and improving failure detection time. Option A, fast hellos, refers to faster hello packets, but does not specifically address CPU impact. Option B, BFD (Bidirectional Forwarding Detection), is aimed at faster failure detection in a more general context, not specifically tied to OSPF's LSA management. Option D, LSA delay interval, would increase the delay in LSA processing, contrary to the goal of minimizing failure detection time.
