CompTIA Network+ (N10-007) — Question 7

A network technician is troubleshooting wireless network issues in a crowded office complex and suspects there is interference from nearby wireless networks.
Which of the following should the technician perform to discover possible interference?

Answer options

• A. Site survey
• B. Vulnerability scanning
• C. Wardriving
• D. Checking logical diagram
• E. Bandwidth test

Correct answer: A

Explanation

The correct answer is A, Site survey, as it involves assessing the environment to identify sources of interference from other wireless networks. The other options do not directly address interference: B (Vulnerability scanning) focuses on security weaknesses, C (Wardriving) is about mapping networks rather than troubleshooting, D (Checking logical diagram) is about network design, and E (Bandwidth test) measures performance, not interference.
