If the active node fails health checks and there is no stay-primary configuration preventing it, what happens?

• A. The active node remains active.
• B. The standby is promoted automatically.
• C. The HA pair stops functioning.
• D. Both nodes reboot.

Answer: (B)

When the active node is unhealthy, Citrix ADC HA is designed to maintain service by failing over to the other unit. If there’s no stay-primary configuration preventing it, the standby unit is promoted automatically to active. This preserves availability, with the previous active becoming the new standby. The failover is automatic and aims to minimize downtime; it does not cause the entire pair to stop functioning or force both nodes to reboot. Stay-primary is what would prevent this automatic promotion if you needed the current active to remain in place for maintenance or other reasons.
