A branch office needs to secure a small network closet that lacks nearby power outlets and network drops. Management wants a control that will still work during power outages, does not depend on authentication servers, and can be re-issued to new employees if necessary. Which physical access method BEST meets these requirements?
Deploy an RFID smart-card reader connected to the company's IAM system
Mount a fingerprint scanner that unlocks the door electronically
Use a Bluetooth-enabled padlock managed through a mobile app
Install a standard mechanical lock that uses cut metal keys
A traditional keyed door lock operates purely mechanically, so it continues to function during power failures and does not require any network or back-end authentication services. Keys can be cut or re-issued as staff change, satisfying the requirement for issuing duplicates. Smart cards, biometric readers, and Bluetooth locks all need electric power and, in most deployments, some form of network or controller for authentication, making them unsuitable for this scenario.
