CompTIA Security+ (SY0-501) — Question 130

The availability of a system has been labeled as the highest priority. Which of the following should be focused on the MOST to ensure the objective?

Answer options

• A. Authentication
• B. HVAC
• C. Full-disk encryption
• D. File integrity checking

Correct answer: B

Explanation

HVAC is critical for maintaining the physical environment and preventing overheating, which directly impacts system uptime. While authentication, full-disk encryption, and file integrity checking are important for security, they do not directly address the immediate needs of system availability like HVAC does.
