Show answer & explanationAnswer & explanation
Correct answer: D. Securing the wiring closets and server rooms.
Securing physical locations like wiring closets and server rooms is a fundamental best practice for protecting network devices from unauthorized physical access, theft, or tampering. Other options address logical security but not physical.
Why the other options are wrong
- A. Strong passwords protect against unauthorized logical access, not physical tampering.
- B. ACLs control network traffic flow and access to device services, not physical access.
- C. SNMPv3 provides secure network monitoring but doesn't prevent physical access.
Physical Security
Physical security refers to the protection of physical assets, including network infrastructure, from unauthorized access, damage, or theft.
- Crucial for data center and wiring closet protection
- Involves locks, surveillance, access controls
- Prevents direct tampering with hardware
Memory trick: Physical protection starts with the physical space.
