CompTIA A+ Core 2 (220-1102) — Question 139

A mobile phone user has downloaded a new payment application that allows payments to be made with a mobile device. The user attempts to use the device at a payment terminal but is unable to do so successfully. The user contacts a help desk technician to report the issue. Which of the following should the technician confirm NEXT as part of the troubleshooting process?

Answer options

• A. If airplane mode is enabled
• B. If Bluetooth is disabled
• C. If NFC is enabled
• D. If Wi-Fi is enabled
• E. If location services are disabled

Correct answer: C

Explanation

The correct answer is C because NFC (Near Field Communication) must be enabled for mobile payment applications to communicate with payment terminals. The other options are less relevant to the functionality of mobile payments; airplane mode, Bluetooth, Wi-Fi, and location services do not directly impact the ability to perform NFC transactions.
