CompTIA A+ Core 2 (220-1002) — Question 382

A technician has been tasked with installing a workstation that will be used for point-of-sale transactions. The point-of-sale system will process credit cards and loyalty cards.
Which of the following encryption technologies should be used to secure the workstation in case of theft?

Answer options

• A. Data-in-transit encryption
• B. File encryption
• C. USB drive encryption
• D. Disk encryption

Correct answer: D

Explanation

Disk encryption is the most appropriate choice for securing a workstation against theft, as it encrypts the entire hard drive, making the data inaccessible if the device is stolen. Data-in-transit encryption protects data being transmitted but does not safeguard data at rest. File encryption secures individual files rather than the whole system, while USB drive encryption is limited to external storage devices.
