CompTIA Security+ (SY0-501) — Question 517

In highly secure environments where the risk of malicious actors attempting to steal data is high, which of the following is the BEST reason to deploy Faraday cages?

Answer options

• A. To provide emanation control to prevent credential harvesting
• B. To minimize signal attenuation over distances to maximize signal strength
• C. To minimize external RF interference with embedded processors
• D. To protect the integrity of audit logs from malicious alteration

Correct answer: C

Explanation

The correct answer is C because Faraday cages are specifically designed to block external radio frequency interference, which can compromise the functioning of embedded processors. The other options either misinterpret the function of Faraday cages or relate to different security measures that do not directly involve the protection against RF interference.
