CompTIA A+ Core 1 (220-1201) — Question 46

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

Answer options

• A. CPU
• B. NIC
• C. HDD
• D. RAM

Correct answer: B

Explanation

The Network Interface Card (NIC) is responsible for connecting the computer to the network, and if it is failing, it can lead to slow network speeds. While the CPU, HDD, and RAM can affect overall system performance, they do not directly impact network speed like a faulty NIC would.
