Scenario: A Citrix Administrator is configuring a Citrix ADC high availability (HA) pair. The administrator needs to ensure that one Citrix ADC is UP and primary at all times to guarantee that business websites are always available.
In the event that both nodes become unavailable or fail a health check, what does the administrator need to do to ensure that the Citrix ADCs still handle web traffic?
To ensure that one Citrix ADC remains UP and primary at all times, and to handle web traffic even if both nodes become unavailable or fail a health check, the administrator needs to configure HA fail-safe mode on each Citrix ADC independently. This ensures that each Citrix ADC can independently determine when it needs to take over, providing continuous availability for the business websites.
