A network architect must ensure only certain departments can access specific resources while on premises.

Comprehensive and Detailed Explanation From Exact Extract:

Geofencing is a network access control method that enforces restrictions based on location data. In this scenario, the organization requires access to be permitted only when users are on premises (i.e., within a specific physical location). Geofencing can be implemented using source IP ranges or GPS-based location data to define boundaries (fences). This allows access to certain applications or services only when the user is inside a designated network or area.

MFA (Option A) provides identity assurance but does not enforce physical location-based restrictions.

UEBA (Option C) provides behavioral analytics but is not used for real-time access control.

PKI (Option D) provides identity validation through certificates but is not location-aware.

Relevant Extract from CompTIA CloudNetX CNX-001 Official Study Guide:

“Geofencing allows organizations to define physical or logical boundaries that restrict or allow access based on user location. Policies can be configured to allow access only when users are on a trusted campus or corporate network, denying requests originating from outside the geofenced area.”
