CompTIA IT Fundamentals (FC0-U51) — Question 3

A user is at the office and has a cellular phone that previously functioned properly. The phone is powered on with a fully charged battery. However, the phone does not have connectivity. Which of the following describes the problem?

Answer options

• A. Phone is disconnected from WiFi
• B. Provider is conducting system testing
• C. MAC address is bad
• D. Phone is in airplane mode

Correct answer: D

Explanation

The correct answer is D because if the phone is in airplane mode, it disables all wireless communications, preventing connectivity. Options A and B are not relevant since they do not explain a lack of connectivity given the phone's status. Option C, regarding a bad MAC address, is unlikely to be the cause if the phone was previously functioning properly.
