CompTIA Network+ (N10-007) — Question 453

A junior technician deployed new computers in a company, and users are reporting issues with file transfers to network shares being slower than with the previous computers. The network administrator verifies the switch's gigabit ports are set to autonegotiate. Which of the following should the administrator perform NEXT to determine the issue?

Answer options

• A. Change the default gateway on the new computers.
• B. Update the drivers for the NIC cards.
• C. Move the computers to a different VLAN.
• D. Determine if the NIC speed on the computers is configured correctly.

Correct answer: D

Explanation

The correct answer is D because verifying the NIC speed ensures that the new computers are capable of utilizing the network's full capacity. If the NIC is set to a lower speed, it would directly impact file transfer rates. Options A, B, and C do not specifically address the immediate concern of network speed related to file transfers.
