CompTIA Cloud+ (CV0-003) — Question 3

Some VMs that are hosted on a dedicated host server have each been allocated with 32GB of memory. Some of VMs are not utilizing more than 30% of the allocation. Which of the following should be enabled to optimize the memory utilization?

Answer options

• A. Auto-scaling of compute
• B. Oversubscription
• C. Dynamic memory allocations on guests
• D. Affinity rules in the hypervisor

Correct answer: C

Explanation

Enabling Dynamic memory allocations on guests allows the hypervisor to adjust the amount of memory allocated to each VM based on its current needs, thereby optimizing memory utilization. The other options, such as Auto-scaling of compute and Oversubscription, do not directly address the inefficient memory allocation issue, while Affinity rules pertain to VM placement rather than memory management.
