CompTIA A+ Core 1 (220-1201) — Question 144

A technician installs an upgraded wireless access point. The technician then notices the activity light comes on briefly and turns off. The access point continues to exhibit this behavior repeatedly and does not come online. Which of the following is the most likely cause of this issue?

Answer options

• A. High latency
• B. Port flapping
• C. External interference
• D. Channel conflict

Correct answer: B

Explanation

The correct answer is B, port flapping, which occurs when a port rapidly switches between up and down states, causing connectivity issues. High latency (A) refers to delays in network communication, which would not cause the access point to fail to come online. External interference (C) and channel conflict (D) may affect performance but are less likely to result in the described behavior of the access point.
