Citrix ADC 13 Advanced Topics – Security, Management and Optimization — Question 80

Scenario: A Citrix Administrator configured a Citrix ADC active-passive, high availability (HA) pair. The HA pair failed over and customers were unable to access hosted websites. The administrator troubleshoots and discovers that the upstream router is NOT updating its ARP table.

What can the administrator configure to resolve this issue?

Answer options

• A. Independent Network Configuration (INC) mode
• B. Route monitor
• C. HA monitor
• D. Virtual MAC

Correct answer: D

Explanation

Configuring a Virtual MAC allows the upstream router to recognize the MAC address of the active Citrix ADC in an HA pair, ensuring proper communication and ARP table updates. The other options, such as Route monitor and HA monitor, do not directly address the issue of the router's ARP table not being updated, while INC mode is unrelated to ARP resolution.
