CompTIA Cloud+ (CV0-003) — Question 245

An engineer is investigating potential performance issues in a hypervisor platform. When comparing the allocated versus actual resources, the engineer notices the platform is oversubscribed. Which of the following is MOST likely the immediate cause of the performance issues?

Answer options

• A. Dynamic allocation
• B. Oversubscription
• C. Ballooning
• D. Transparent page sharing

Correct answer: B

Explanation

The correct answer is B, as oversubscription directly leads to resource contention and can degrade performance. Dynamic allocation, ballooning, and transparent page sharing are techniques that can help manage resources but do not inherently cause performance issues like oversubscription does.
