CompTIA Network+ (N10-008) — Question 92

A technician is connecting DSL for a new customer. After installing and connecting the on-premises equipment, the technician verifies DSL synchronization. When connecting to a workstation, however, the link LEDs on the workstation and modem do not light up. Which of the following should the technician perform during troubleshooting?

Answer options

• A. Identify the switching loops between the modem and the workstation.
• B. Check for asymmetrical routing on the modem.
• C. Look for a rogue DHCP server on the network.
• D. Replace the cable connecting the modem and the workstation.

Correct answer: D

Explanation

The correct answer is D because a faulty or damaged cable could prevent the modem and workstation from establishing a connection, resulting in the link LEDs not lighting up. Options A, B, and C are less relevant as they address different network issues that would not directly affect the physical connection between the modem and workstation.
