CISSP Physical Security 4

Question 1

Which type of lock is MOST resistant to lock-picking attacks?

Accepted Answer

High-security disc detainer lock

Answer

High-security disc detainer locks use rotating discs with tight tolerances, making them significantly more resistant to picking tools.

Question 2

A CISSP candidate is reviewing a data center's power redundancy. Which configuration provides the HIGHEST availability?

Accepted Answer

Dual utility feeds with UPS and generator (2N configuration)

Answer

A 2N configuration with dual utility feeds, UPS, and generator provides full redundancy with no single point of failure for power.

Question 3

When designing a secure parking lot adjacent to a corporate facility, which CPTED principle reduces the risk of theft and assault?

Accepted Answer

Ensuring adequate lighting throughout the lot

Answer

Adequate lighting removes dark hiding spots, increases natural surveillance, and is a core CPTED deterrent for parking area crime.

Question 4

Which document formally defines the requirements for physical security controls that a co-location (colo) facility must meet?

Accepted Answer

Service Level Agreement (SLA)

Answer

An SLA with the colo provider formally specifies the physical security, uptime, and environmental controls the facility must maintain.

Question 5

A security team discovers that someone has been using a cloned RFID badge to access the building. Which control would BEST prevent this attack?

Accepted Answer

Implementing multi-factor authentication (badge + biometric)

Answer

Multi-factor authentication combines something-you-have (badge) with something-you-are (biometric), so a cloned badge alone is insufficient.
