Explanation

When the primary BES instance falls below the failover threshold, the standby server takes the initiative - it checks its own health score to confirm it's capable of assuming the primary role (C), then sends a demotion request to the primary, telling it to step down (B). This two-step handshake ensures the standby is healthy before committing to a takeover.

Why A is wrong: The primary does not send a promotion request to the standby. The primary is degraded - the standby drives the failover, not the failing server.

Why D is wrong: The primary does not check the standby's health score. Health verification flows the other way: the standby checks itself before acting.

Memory tip: Think "standby takes charge" - the standby does both actions (self-check, then demote the primary). The degraded primary is essentially passive in this exchange, just like a sick employee doesn't pick their replacement - management (the standby) decides.
