A startup needs to deploy a web application that experiences unpredictable traffic spikes. They want to scale their infrastructure quickly without purchasing new hardware. Which virtualization benefit directly addresses this need?

Rapid provisioning and elasticity of virtual machines

Resource optimization through server consolidation

Enhanced security through VM isolation

Reduced power consumption through hardware consolidation

An administrator notices that a VM is experiencing high latency and poor performance. The VM is configured with 4 vCPUs and 8 GB RAM, but the host has 16 vCPUs and 64 GB RAM. The administrator suspects resource contention. Which action would most directly address the performance issue?

Enable memory ballooning on the VM

Increase the VM's allocated vCPUs to 8

Check the host's CPU and memory utilization for overcommitment

Migrate the VM to a different host using vMotion

An administrator is troubleshooting a VM that is performing poorly. The VM is configured with 4 vCPUs and 8 GB RAM. The host has 16 vCPUs and 64 GB RAM, and is running 4 other VMs. The administrator checks the host's performance metrics and sees that CPU utilization is at 90% and memory utilization is at 80%. What is the most likely cause of the VM's poor performance?

Insufficient vCPUs allocated to the VM
