The correct answers are E. NFC and F. Location services .
According to CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Security:
NFC (Near-Field Communication) : Enables the device to communicate with contactless payment terminals, which is essential for detecting nearby stores that accept contactless payments.
Location services : Allows the application to determine the user’s geographic location so it can provide notifications only when the user is near a participating store.
Why the other options are incorrect:
A. MDM (Mobile Device Management): Manages device policies but does not enable location-based notifications or contactless payments.
B. Contact syncing: Synchronizes contacts; unrelated to payment notifications.
C. Bluetooth: Can be used for some proximity services, but NFC is required for contactless payment detection.
D. Hotspot: Provides internet access; not required for proximity detection in this context.
