Which concept describes the creation of virtual boundaries based on geographical locations and coordinates to trigger access controls?

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

Answer: (B)

Geofencing is the technique of creating virtual boundaries tied to real-world geographic areas and using those boundaries to trigger actions when a device or user crosses the boundary or enters within it. This setup relies on location data from GPS, cellular, or Wi‑Fi to determine when to grant or deny access, making it ideal for enforcing access controls based on where someone or something is located.

Geolocation, in contrast, is simply the process of figuring out a device’s actual location; it doesn’t define a boundary or automatically trigger rules. Geotagging attaches location data to content like photos, not for enforcing access controls. DNS over HTTPS focuses on encrypting DNS traffic to protect privacy and has nothing to do with location-based access control.
