Question 1

A small business has just moved to a new office location that shares the building with other tenants. In order to protect their critical IT assets, they want to implement a physical barrier. Which of the following barriers would be most suitable?

Correct Answer: Install a door lock with keycard access

Installing a door lock with keycard access provides better access control and security compared to other options. While a security guard may deter criminals, it doesn't physically protect the IT assets. A safe or deadbolt lock is less secure and more easily tampered with. A combination lock can be bypassed by an unauthorized person who knows the combination. Relying on building security neglects the specific security needs of the small business.

Question 2

A financial institution's data center has experienced several physical security breaches in the past. Security management decided to perform a risk assessment. What is the most important aspect to consider?

Correct Answer: Evaluate the effectiveness of current physical security controls

The risk assessment's primary goal is to identify current vulnerabilities and weaknesses. Evaluating the effectiveness of current physical security controls is pivotal in identifying areas for improvement, whereas other options may divert attention away from that crucial focus.

Question 3

A company wants to improve the physical security of its data center by installing a mechanical barrier to deter unauthorized access. Which of the following barriers would effectively slow down intruders without being overly intrusive?

Correct Answer: Bollards

Bollards are short, sturdy posts that provide a physical barrier, slowing down intruders while not being intrusive. Razor wire, electric fences, and barbed wire can be harmful to people and are generally used in high-security settings. A revolving door doesn't provide a strong mechanical barrier, and a moat is unrealistic and expensive.
