Network Defense Essentials (NDE) Practice Exam

Which of the following activities is a physical security measure for maintaining servers and backup devices?

1. Use of fire alarms

2. Use of CCTV surveillance

3. Use rack mount servers

4. Use of biometric access

The correct answer is: Use rack mount servers

Utilizing rack mount servers is considered a physical security measure because it facilitates better organization and containment of critical hardware. Rack mount servers allow for a compact arrangement of servers in a secure rack, which can be locked to prevent unauthorized access. This configuration not only maximizes physical security but also improves safety by optimizing airflow and reducing the potential for overheating, thereby protecting the servers and backup devices from physical threats, such as environmental hazards or unauthorized tampering. While other activities like fire alarms, CCTV surveillance, and biometric access contribute to physical security, they serve different functions. Fire alarms alert personnel to potential fire hazards, CCTV provides monitoring of physical spaces, and biometric access controls user authentication. Rack mounting specifically addresses the organization, secure housing, and operational integrity of servers and backup devices, making it a fundamental physical security means in a data center environment.
