Which security feature is used to physically secure servers in data centers?

• A. Secure servers in a data center
• B. Cloud hosting
• C. Personal devices
• D. Public networks

Answer: (A)

Physical security measures in a data center protect hardware from theft, tampering, and environmental hazards by controlling who can access the equipment and how it is monitored. Securing servers inside the data center is exactly about implementing those protections on the physical hardware, using controls like restricted access, biometric or badge entry, surveillance cameras, tamper-evident seals, and locked racks. These protections help ensure that only authorized personnel can interact with the servers and that any physical tampering is detectable. In contrast, cloud hosting involves placing servers off-site and relying on someone else’s physical security, personal devices are not about protecting data center hardware, and public networks expose systems rather than securing them physically.
