Explanation

Option A is correct because in a dual-link hot backup scenario, when the active link fails and the standby takes over, the switchover process involves re-establishing tunnel states, renegotiating sessions, and synchronizing forwarding tables - all of which introduce measurable delay. During this transition window, in-flight packets on the tunnel are dropped and new user authentication/authorization requests cannot be processed, causing real service interruption.

Option B ("False") is incorrect because it implies the switchover is seamless or instantaneous, which is not the case. Even with hot standby, "hot" refers to the standby being pre-loaded and ready, not that the switch itself is zero-downtime - there is always a finite convergence period.

Memory tip: Think of "hot" in hot backup as meaning the spare is warm and waiting, not that the handoff is instant and invisible. The longer the switchover time, the longer the gap - and gaps always cost you sessions or new logins.
