Which statement about unbinding a backend server from a load-balancing virtual server is true?

• A. It stops all traffic to the vServer
• B. All traffic to that server is redirected to others
• C. The vServer stops working
• D. Nothing changes

Answer: (B)

When you unbind a backend server from a load-balancing vServer, you’re removing that server from the pool that can handle requests for that vServer. The load balancer then continues to route new client requests to the remaining bound and healthy servers using the configured distribution method. So the traffic that would have gone to the unbound server is redistributed to the other servers. The vServer stays up and continues serving requests as long as at least one backend remains healthy. Only if there are no other backends bound (or all are unhealthy) would the vServer be unable to serve traffic.
