CompTIA Security+ (SY0-501) — Question 528

Which of the following should a technician use to protect a cellular phone that is needed for an investigation, to ensure the data will not be removed remotely?

Answer options

• A. Air gap
• B. Secure cabinet
• C. Faraday cage
• D. Safe

Correct answer: C

Explanation

A Faraday cage effectively blocks electromagnetic signals, preventing any remote access or data wiping from external sources. An air gap and secure cabinet do not specifically prevent remote data removal, and while a safe protects physical integrity, it does not address electronic signals.
