CV0-004 Practice Question: Notices that a virtual machine running a critical…
A cloud engineer notices that a virtual machine running a critical application is experiencing high CPU usage. The engineer needs to resolve the issue without affecting other VMs on the same host. Which of the following actions should the engineer take first?
⚠ Common exam trap
CompTIA often tests the misconception that increasing a VM's resource allocation is the first troubleshooting step, when in fact it can cause resource starvation for other VMs; the correct first action is to migrate the VM to balance the load.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Migrate the VM to another host in the cluster.
Migrating the VM to another host in the cluster (option C) is the correct first action because it immediately offloads the CPU pressure from the current host without impacting the VM's operation or other VMs. This leverages VMware vMotion or Microsoft Hyper-V Live Migration to move the running VM to a less-utilized host, isolating the performance issue while preserving uptime and avoiding resource contention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Restart the VM to clear the high CPU usage.
Why it's wrong here
Restarting causes downtime and may not fix the root cause.
- ✗
Increase the CPU allocation for the VM.
Why it's wrong here
This may not be possible if the host is out of CPU resources.
- ✓
Migrate the VM to another host in the cluster.
Why this is correct
Live migration moves the VM to a less loaded host, resolving the issue without downtime.
- ✗
Add another VM to the same host to distribute load.
Why it's wrong here
Adding another VM would increase the load on the host.
