CompTIA A+ Core 2 (220-1102) — Question 77

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 effective method for securing data on a workstation, especially for sensitive information such as credit card details. While data-in-transit encryption protects data traveling over networks and file or USB drive encryption secures specific files or drives, disk encryption ensures that all data on the entire disk is protected against unauthorized access in case of theft.
