Which device would most likely be used to manage and monitor entry to a secure data center using authentication factors like badges and biometric data?
A physical access control device is designed to secure environments by restricting and monitoring physical entry using various forms of authentication. Badges and biometric data are commonly used as authentication methods with these systems. While routers and firewalls are important for network security, they do not manage physical entry. A VPN headend is used for creating and managing virtual private networks, not for physical access control.
