CompTIA A+ Core 1 (220-1001) — Question 34

A user brings in a smartphone for repair. The device is unable to send/receive calls or connect to WiFi. All applications on the device are working unless they require connectivity.
Which of the following is MOST likely causing the problem?

Answer options

• A. Airplane mode
• B. Tethering
• C. Disabled hotspot
• D. VPN

Correct answer: A

Explanation

The most likely reason for the inability to make calls or connect to WiFi is that Airplane mode is enabled, which disables all wireless communication. The other options, such as tethering, disabled hotspot, and VPN, do not prevent the device from connecting to cellular networks or WiFi entirely, but rather affect specific functionalities.
