What type of VM is characterized by a CPU usage greater than 90% and leading to performance bottlenecks?

  1. Constrained VM

  2. Bully VM

  3. Over-provisioned VM

  4. Inactive VM

The correct answer is: Constrained VM

The term "Constrained VM" accurately describes a virtual machine experiencing high CPU usage, specifically when it exceeds 90%. This situation indicates that the virtual machine is under significant load, resulting in performance bottlenecks due to a lack of available CPU resources to handle its workloads effectively. Consequently, this can lead to slow response times and degraded performance for applications running on the VM. This scenario typically arises when the workload demands on the VM exceed the available resources allocated to it. In cloud and virtualization environments, it is essential to monitor CPU usage closely, as prolonged periods of high CPU utilization can signal the need for resource optimization or reallocation to ensure that performance remains within acceptable thresholds. Understanding this context helps in optimizing the virtual environment, ensuring that resources are allocated appropriately to prevent further performance degradation.
