A customer reports slow network speeds. Which of the following components is most likely failing?

The correct answer is B. NIC. The Network Interface Card (NIC) is the hardware responsible for all network communication. A failing or degraded NIC can negotiate at a lower link speed (e.g., dropping from 1 Gbps to 100 Mbps or 10 Mbps), experience packet loss, or have driver issues-all resulting in noticeably

Explanation

The Network Interface Card (NIC) is the hardware responsible for all network communication. A failing or degraded NIC can negotiate at a lower link speed (e.g., dropping from 1 Gbps to 100 Mbps or 10 Mbps), experience packet loss, or have driver issues-all resulting in noticeably slow network throughput. The CPU, HDD, and RAM can indirectly affect overall system performance, but a complaint specifically about slow network speeds points directly to the NIC as the most likely hardware culprit.
