An administrator is attempting to connect a laptop to a server via RJ-45 ports on both a device and a CAT5 patch cable. All of the IP settings have been verified to be correct, yet there is a connectivity problem. Which of the following would MOST likely fix the IP connectivity problem?

A.
Wires 1, 2 and 3, 6 need to be swapped on one end of the connecting cable.

B.
Use the DB-9 port with a DB-9 to RJ-45 adapter on the server.

C.
Manually adjust the duplex mode on the servers link.

D.
Configure the laptop to receive a DHCP address from the server, rather than manually setting one.
