CompTIA CySA+ (CS0-003) — Question 210

A system that provides the user interface for a critical server has potentially been corrupted by malware. Which of the following is the best recommendation to ensure business continuity?

Answer options

• A. System isolation
• B. Reimaging
• C. Malware removal
• D. Vulnerability scanning

Correct answer: B

Explanation

Reimaging the system is the most effective way to ensure that any malware is completely removed and the system is restored to a known good state. While malware removal and vulnerability scanning are important, they may not guarantee that all malicious components are eliminated, and system isolation is not a proactive solution for recovery.
