Refer to the exhibit. A connection is being established to IP 1.1.1.1 on port 8080. Which virtual server will handle the connection?
The correct answer is B. host_vs. The host_vs virtual server will handle the connection to IP 1.1.1.1 on port 8080 because it is configured as a Standard virtual server with an exact match for the destination IP and port.

Why each option
The `host_vs` virtual server will handle the connection to IP 1.1.1.1 on port 8080 because it is configured as a Standard virtual server with an exact match for the destination IP and port.
`fwd_8080_vs` is likely a Forwarding (IP) virtual server or configured with a broader destination, making it less specific than an exact match by `host_vs`.
The `host_vs` virtual server is configured to specifically listen on IP 1.1.1.1 and port 8080, making it the precise handler for the incoming connection.
If `host_vs` is the intended handler, `host_ 8080_VS` would either not have the exact matching configuration or `host_vs` would take precedence based on virtual server type or order.
`fwdvs` typically represents a generic Forwarding (IP) virtual server with wildcard IP (0.0.0.0) and port (0), which is the least specific and will not be selected when a more specific virtual server exists.
