Which capability uses a device's location detection to determine whether to grant access to a resource?

• A. Geolocation
• B. Geofencing
• C. Geotagging
• D. DNS Over HTTPS (DoH)

Answer: (A)

Location-based access control works by using the device’s geographic position to decide whether access should be granted. The capability that provides that position is geolocation. By obtaining coordinates through methods like GPS, Wi‑Fi positioning, or cellular data and comparing them to where access is allowed, a system can permit or deny entry to a resource. Geofencing is related in that it defines a boundary and can trigger actions when a device enters or exits it, but the fundamental capability here is obtaining the actual location, which is geolocation. Geotagging just adds location data to content and isn’t used to gate access, and DNS Over HTTPS has no relation to location-based access decisions.
