Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 311

Which protocol is configured on tunnels by default to detect loss, latency, jitter, and path failures in Cisco SD-WAN?

Answer options

• A. TLS
• B. BFD
• C. OMP
• D. BGP

Correct answer: B

Explanation

BFD, or Bidirectional Forwarding Detection, is utilized in Cisco SD-WAN by default to detect network issues such as loss, latency, and jitter. The other options, while relevant to networking, do not provide the same level of monitoring capabilities for tunnels as BFD does.
