CompTIA CySA+ (CS0-003) — Question 243

During a tabletop exercise, engineers discovered that an ICS could not be updated due to hardware versioning incompatibility. Which of the following is the most likely cause of this issue?

Answer options

• A. Legacy system
• B. Business process interruption
• C. Degrading functionality
• D. Configuration management

Correct answer: A

Explanation

The correct answer is A, as legacy systems often have outdated hardware that cannot support newer updates, leading to compatibility issues. The other options do not directly relate to hardware versioning; business process interruption refers to operational disruptions, degrading functionality indicates performance issues, and configuration management deals with maintaining system settings rather than hardware compatibility.
