CompTIA Network+ (N10-009) — Question 45

An office is experiencing intermittent connection issues. A network engineer identifies that the issue occurs whenever someone uses the fax machine that is connected to a switch. Which of the following should the engineer do first to resolve the issue?

Answer options

• A. Run a new Cat 5 line.
• B. Enable 802.1Q tagging.
• C. Change the MTU.
• D. Configure a VLAN.

Correct answer: D

Explanation

Configuring a VLAN can help segment the network traffic, which may resolve the interference caused by the fax machine. Running a new Cat 5 line, enabling 802.1Q tagging, and changing the MTU do not directly address the potential traffic congestion created by the fax machine's operation.
