CompTIA Security+ (SY0-501) — Question 518

Which of the following is the proper use of a Faraday cage?

Answer options

• A. To block electronic signals sent to erase a cell phone
• B. To capture packets sent to a honeypot during an attack
• C. To protect hard disks from access during a forensics investigation
• D. To restrict access to a building allowing only one person to enter at a time

Correct answer: A

Explanation

A Faraday cage is designed to block electromagnetic fields, making it effective in preventing electronic signals from reaching devices like cell phones. Options B and C do not accurately describe the purpose of a Faraday cage, as capturing packets and protecting hard disks involve different security measures. Option D is unrelated to the electromagnetic shielding capabilities of a Faraday cage.
