CompTIA A+ Core 1 (220-1101) — Question 549

A help desk technician is tasked with moving a user's computer to a makeshift office for renovations. Upon moving the computer, the technician notices the network card will not utilize anything beyond 10Mbps half duplex. Which of the following is the most likely issue?

Answer options

• A. The computer is connected with DSL.
• B. The computer is connected to an unmanaged switch.
• C. The computer is configured for NIC teaming.
• D. The computer is connected to a hub.

Correct answer: D

Explanation

The correct answer is D because hubs operate at half duplex and can only support 10Mbps speeds, which would explain the network card's limitations. Options A and B are not relevant as they do not directly cause a limitation to 10Mbps half duplex. Option C is incorrect because NIC teaming generally improves bandwidth and redundancy, not restricts speed.
