Which action will take place when a failover trigger is detected by the active system.
The correct answer is A. The active device will take the action specified for the failure. When a failover trigger is detected by the active system, it executes the specific, predefined action that has been configured for that particular failure event.
Question

Options
- AThe active device will take the action specified for the failure.
- BThe standby device also detects the failure and assumes the active role.
- CThe active device will wait for all connections to terminate and then failover.
- DThe standby device will begin processing virtual servers that have failed, but the active device will continue

Why each option
When a failover trigger is detected by the active system, it executes the specific, predefined action that has been configured for that particular failure event.
When the active system detects a failover trigger, it performs the predefined action associated with that specific trigger, such as ceding the active role to the standby device. These actions are configurable and determine how the system responds to detected failures.
While the standby device eventually assumes the active role, the question specifically asks what action the *active device* takes *upon detection* of the trigger.
Waiting for all connections to terminate is not a typical failover behavior; failover aims for rapid recovery, not graceful indefinite shutdown.
This implies a partial failover or split-brain scenario which is generally undesirable; a full failover means the active device relinquishes its role entirely.
