Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 153

Which mechanism must be chosen to optimize the reconvergence time for OSPF at company location 408817202 that is less CPU-intensive than reducing the hello and dead timers?

Answer options

• A. sso
• B. BFD
• C. Dead Peer Detection keepalives
• D. OSPF demand circuit

Correct answer: B

Explanation

BFD (Bidirectional Forwarding Detection) is specifically designed to provide rapid failure detection for OSPF, making it a suitable choice for optimizing reconvergence time. The other options, while useful in their own contexts, do not specifically address the need for fast detection without significantly increasing CPU load.
