CompTIA Network+ (N10-007) — Question 67

A network technician is attempting to troubleshoot a connectivity issue. The issue is only reported during the evening hours, and only a single workstation loses connectivity. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The router has a time-based ACL, applied for the network segment.
• B. A light source is creating EMI interference, affecting the UTP cabling.
• C. Nightly backups are consuming excessive bandwidth.
• D. The user has violated the AUP, and Internet access has been restricted.

Correct answer: D

Explanation

The correct answer is D because if a user has violated the Acceptable Use Policy (AUP), their Internet access could be restricted during certain hours. The other options are less likely: A suggests a broader issue affecting multiple users, B relates to physical interference which typically wouldn't occur at specific times, and C would likely affect more than just one workstation.
