Which port is used for non-secure high availability communication between Citrix ADC appliances?

• A. 3009
• B. 3008
• C. 3010
• D. 3011

Answer: (C)

Non-secure high availability communication is the channel that keeps two Citrix ADC appliances in sync by exchanging heartbeat and state information so failover can occur reliably. This unencrypted HA channel uses a dedicated port, which is 3010. Ensuring this port is open and reachable between the two appliances on the interconnect network is essential for seamless failover. If you ever opt for encryption, the secure HA channel uses TLS on port 3011, so that traffic between the appliances is encrypted. The other ports listed are not intended for this non-secure HA synchronization.
