CompTIA Network+ (N10-007) — Question 467

A rural municipality has built an external public WiFi meshed network using omnidirectional antennas. After the initial build, the performance meets expectations, and the municipality enters a six-month pilot program in the fall. By the end of the pilot program in the spring, the performance has fallen dramatically. The pilot has a static number of users with no increases in usage from beginning to end. Which of the following would be the MOST likely reason for the performance issues?

Answer options

• A. Too many users in the pilot creating overcapacity issues
• B. Buildings creating reflection issues
• C. Omnidirectional antennas being insufficient for outdoor use
• D. Foliage creating absorption issues

Correct answer: D

Explanation

The correct answer is D because foliage can absorb WiFi signals, leading to decreased performance, especially in outdoor environments. Options A, B, and C do not apply as the user count remained static, and omnidirectional antennas can function outdoors; thus, they are less likely to be the cause of the performance issues.
