An administrator connects a server to an external gigabit switch, but the server can only get a speed of 100Mbps. Which of the following is the most likely cause of this issue?

The correct answer is A. Defective network cable. The most likely cause of a speed mismatch (100Mbps instead of 1Gbps) is a defective or incompatible network cable. Gigabit Ethernet requires at least Cat5e or Cat6 cables; using older cables (e.g., Cat5) or damaged cables can limit speeds to 100Mbps.
