The Ezonexam network administrator wants to ensure that only a single web server can connect to pot Fa0/1 on a catalyst switch. The server is plugged into the switch's Fast Eth. 0/1 port and the network administrator is about to bring the server online. What can the administrator do to ensure that only the MAC address of this server is allowed by switch port Fa0/1? (Choose two)A．Configure port Fa0/1 to accept connections only from the static IP address of the serverB．Configure the MAC address of the server as a static entry associated with port Fa0/1C．Employ a proprietary connector type on Fa0/1 that is incomputable with other host connectorsD．Configure port security on Fa0/1 to reject traffic with a source MAC address other than that of the serverE．Bind the IP address of the server to its MAC address on the switch to prevent other hosts from spoofing the server IP address
