CompTIA Cloud+ Practice Test

In a cloud deployment, what should a CSA confirm to ensure the correct utilization of CPU per virtual instance?

1. The VMs with the most CPU cores available have been selected.

2. Smaller VMs are being selected to reduce the total deployment cost.

3. The deployment is utilizing the recommended amount of CPUs per VM.

4. The alarms on CPU utilization have been enabled.

The correct answer is: The deployment is utilizing the recommended amount of CPUs per VM.

The correct choice is focused on the importance of confirming that the deployment is utilizing the recommended amount of CPUs per virtual machine (VM). This ensures optimal performance and efficiency in resource utilization, which is crucial in a cloud environment where multiple instances may be running concurrently. Utilizing the recommended amount of CPUs helps maintain a balance between performance and resource allocation. If VMs are allocated too few CPUs, they may become bottlenecks, resulting in slow performance and degraded service. Conversely, over-allocating CPUs could lead to unnecessary costs and resource wastage. Therefore, ensuring that the CPU usage adheres to best practices allows for a more efficient cloud deployment. The other options involve considerations that may not directly address the core requirement for effective CPU utilization. Simply selecting VMs with more CPU cores does not guarantee that they will operate efficiently or that the workload will be managed appropriately. Similarly, choosing smaller VMs based solely on cost could lead to performance issues if those VMs are not equipped to handle the required load. Lastly, while enabling alarms on CPU utilization is a useful monitoring strategy, it’s a reactive measure that does not confirm that the deployment is already using the optimal CPU resources, which is essential for proactive management of the cloud infrastructure.
