To ensure that one Citrix ADC is always up and primary in an HA pair, what must be configured?

• A. Configure HA fail-safe mode on the primary Citrix ADC only.
• B. Disable HA fail-safe mode on each Citrix ADC independently.
• C. Configure HA fail-safe mode on each Citrix ADC independently.
• D. Disable HA fail-safe mode on the primary Citrix ADC only.

Answer: (C)

HA fail-safe mode is a protective setting that governs how an HA pair decides which unit stays primary when health or communication issues arise. To guarantee that one Citrix ADC remains up and the other ready to take over, you must enable fail-safe mode on both devices and configure it independently. When each ADC enforces fail-safe, both sides participate in failover decisions, ensuring a reliable promotion of the secondary if the primary becomes unhealthy. If only one unit has fail-safe enabled, the failover behavior can become inconsistent, risking split-brain or longer outages when problems occur. So, enabling fail-safe on every unit ensures a single, healthy primary at all times.
