Scenario: a Citrix Administrator Configured Citrix ADC Load Balancing to Send

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 vServer 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?

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