Certified Information Systems Auditor (CISA) — Question 349

Which of the following is the GREATEST advantage of utilizing guest operating systems in a virtual environment?

Answer options

• A. They can be logged into and monitored from any location.
• B. They prevent access to the greater environment via Transmission Control Protocol/Internet Protocol (TCP/IP)
• C. They can be wiped quickly in the event of a security breach.
• D. They are easier to containerize with minimal impact to the rest of the environment

Correct answer: C

Explanation

The correct answer, C, highlights that guest operating systems can be quickly removed in case of a security compromise, ensuring swift recovery. Option A, while true, does not represent a primary advantage over the others. Option B is inaccurate as guest OSs can still be vulnerable through TCP/IP. Option D, although it discusses containerization, does not address the security aspect as effectively as option C.
