Citrix Virtual Apps and Desktops 7 Associate — Question 107

Scenario: A Citrix Administrator has configured a Citrix ADC active-passive high availability (HA) pair. When the HA pair fails over, customers are unable to access the hosted websites. After some troubleshooting, the administrator found that the upstream router was NOT updating its ARP table.
What can the administrator configure to resolve this issue?

Answer options

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

Correct answer: A

Explanation

Configuring a Virtual MAC allows the upstream router to correctly recognize the active Citrix ADC in an HA pair, ensuring that its ARP table is updated accordingly. The other options, such as Independent Network Configuration mode, Route Monitor, and HA monitor, do not directly address the issue of ARP table updates in this context.
