Scenario: An engineer has configured a virtual server that users access using HTTP port 80. The
web application also uses TCP port 81 and 8080 for non-user access. The engineer would like to
prevent users from connecting to web servers if any of the ports go down. How should the engineer
set this configuration to ensure service availability?

A.
Increase the monitor threshold.

B.
Lower the server timeout value.

C.
Create additional virtual servers for ports 81 and 8080.

D.
Create monitors for ports 81 and 8080, and bind to the service or service group.
