You are the network administrator for a small consulting firm. The office network consists of 30 computers, one server, two network printers, and a switch. Due to security concerns, there is no wireless network available in the office. One of your users, Bob, travels to client sites and is generally not in the office. When Bob goes to client sites, he typically just connects to their wireless networks. When he's in the office, Bob connects his laptop to the network with an Ethernet cable. You need to make sure that Bob's laptop is setup so that when he plugs the Ethernet cable into his laptop, no further configuration is needed. Which of the following would be the BEST option to achieve this?
