Citrix Access Control Administration — Question 17

Scenario: A Citrix Administrator configured Citrix ADC load balancing to send requests to one of three identical backend servers. Each server handles multiple protocols, and load balancing is set up in round-robin mode. The current load-balancing setup on the Citrix ADC is:
One load-balancing virtual server with one externally accessible VIP
One service created for each protocol type
One server entity for each backend resource
During business hours, the administrator wants to make changes to one backend server without affecting the other servers
What is the most efficient way for the administrator to ensure that all traffic is routed away from the server without impeding responses from other resources?

Answer options

• A. Disable the backend server entity targeted for change.
• B. Disable the load-balancing virtual server.
• C. Disable the backend service entity targeted for change.
• D. Unbind the correct server entity from the load-balancing virtual server.

Correct answer: A

Explanation

The correct answer is A because disabling the backend server entity targeted for change removes it from the load balancing pool without affecting the other servers. Option B is incorrect as it would stop all traffic and impact other resources. Option C only disables the service for that protocol, not the entire server, and option D would leave the server still active in the pool, which is not desired.
