Certified Information Systems Auditor (CISA) — Question 7

Which of the following is the MOST significant risk associated with the use of virtualization?

Answer options

• A. Insufficient network bandwidth
• B. Single point of failure
• C. Inadequate configuration
• D. Performance issues of hosts

Correct answer: B

Explanation

The most critical risk in virtualization is the single point of failure, as a failure in the host can impact all virtual machines running on it. Other options, while valid concerns, do not pose as significant a risk to the overall system's reliability and availability as a single point of failure does.
