A company's network equipment is stored in a wiring closet that is shared with the janitorial staff. The closet door has a standard doorknob lock. The security team wants to prevent unauthorized access while allowing janitors to clean during off-hours. Which solution best meets this need?

Use a smart lock that allows scheduling temporary access codes for janitors during cleaning hours.

Keep the existing lock and give janitors a key to the closet.

Install a biometric fingerprint reader and enroll only IT staff.

Replace the doorknob lock with a cipher lock that requires a code known only to IT staff.

A company's network operations center (NOC) is located on the ground floor of a building with large windows. Management wants to prevent unauthorized physical access while allowing natural light into the room. Which solution best meets both requirements?

Install a solid wall in front of the windows.

Use security film on the windows and install a window sensor that triggers an alarm.

Install a roll-down metal shutter that can be closed at night.

Replace the windows with glass blocks.

A server room has a raised floor with cabling underneath. The room's HVAC system is set to 22°C (71.6°F) and 50% relative humidity. Recently, several servers have been overheating and shutting down. Which environmental control adjustment is most likely to address the issue?

Install a fire suppression system that uses inert gas to cool the room.

Ensure the HVAC system provides adequate airflow to the front of the server racks and that cold air reaches the intakes.

Increase the HVAC temperature setpoint to 25°C (77°F) to reduce cooling costs.

Decrease the relative humidity to 20% to reduce condensation risk.

What is the primary purpose of implementing a two-factor access control system at the entrance to a network operations center?

To monitor who enters the facility

To ensure only authorized personnel can enter by requiring two separate credentials

To provide a backup entry method in case one credential is lost

To allow visitors to enter without a badge
