CompTIA Security+ (SY0-501) — Question 112

New magnetic locks were ordered for an entire building. In accordance with company policy, employee safety is the top priority.
In case of a fire where electricity is cut, which of the following should be taken into consideration when installing the new locks?

Answer options

• A. Fail safe
• B. Fault tolerance
• C. Fail secure
• D. Redundancy

Correct answer: A

Explanation

The correct answer is A, Fail safe, because in the event of a power failure during a fire, a fail-safe mechanism ensures that the locks unlock, allowing for safe exit. On the other hand, Fail secure (C) would keep the locks locked during a power outage, which could endanger lives. Fault tolerance (B) and redundancy (D) are important in system design but do not directly address the immediate safety concerns related to locking mechanisms in emergencies.
