In a load-balancing setup with three identical backend servers, which action best enables maintenance on one server without impacting others?

• A. Disable the backend service entity
• B. Disable the backend server entity
• C. Disable the load-balancing vServer
• D. Unbind the server entity

Answer: (B)

When you need to perform maintenance on one backend node without affecting the others, remove that node from the pool. In Citrix ADC, a backend server is represented by a server entity. Disabling that server entity marks the node as unavailable, so the load balancer stops directing traffic to it while the remaining healthy servers continue to handle requests. This lets you work on the isolated server and then re-enable it to rejoin the pool, ensuring minimal disruption to the overall service. This approach keeps the rest of the pool fully active and avoids impacting the vServer itself or needing more complex reconfiguration.
