Question

Which protocol detects path status (up/down), measures loss/latency/jitter, and measures the quality of the IPsec tunnel MTU?

A. DTLS
B. BFD
C. OMP
D. IP-SLA

Answer

B. BFD

Explanation

The correct answer is B. BFD (Bidirectional Forwarding Detection).

BFD is a protocol that detects the status of the IPsec tunnel path (up/down), measures loss, latency, and jitter, and measures the quality of the IPsec tunnel MTU. It provides a way for devices to exchange heartbeats and detect if the tunnel is operational or not.
