Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 166

Which state indicates that BFD is missing on a peer when troubleshooting DMVPN?

Answer options

• A. DOWN(D)
• B. NONE(N)
• C. UP(U)
• D. INVALID(I)

Correct answer: B

Explanation

The correct answer is B, as the 'NONE' state indicates that BFD is not configured or missing on the peer. The 'DOWN' state (A) implies that the peer is unreachable, 'UP' (C) shows that the peer is operational, and 'INVALID' (D) suggests a misconfiguration, none of which specifically denote the absence of BFD.
