CompTIA CySA+ (CS0-003) — Question 14

An analyst is reviewing a vulnerability report and must make recommendations to the executive team. The analyst finds that most systems can be upgraded with a reboot resulting in a single downtime window. However, two of the critical systems cannot be upgraded due to a vendor appliance that the company does not have access to. Which of the following inhibitors to remediation do these systems and associated vulnerabilities best represent?

Answer options

• A. Proprietary systems
• B. Legacy systems
• C. Unsupported operating systems
• D. Lack of maintenance windows

Correct answer: A

Explanation

The correct answer is A, as proprietary systems are those that are owned or controlled by a specific vendor, limiting access to necessary updates. The other options do not fit as well; legacy systems refer to outdated technology, unsupported operating systems denote software that no longer receives updates, and lack of maintenance windows pertains to timing issues rather than access limitations.
