CV0-004 Practice Question: A cloud administrator is deploying a virtual…
A cloud administrator is deploying a virtual machine (VM) in a public cloud and must ensure that the VM can be recovered quickly in case of failure. The administrator configures the VM to use a managed disk. What additional deployment step should be taken to meet the recovery objective with minimal cost?
⚠ Common exam trap
Many candidates confuse high availability (e.g., availability sets or pilot light deployments) with backup and recovery, assuming that redundancy alone satisfies the recovery objective, when in fact snapshots provide a lower-cost, backup-focused solution for quick recovery after failure.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure automated snapshots of the managed disk on a schedule.
Configuring automated snapshots of the managed disk provides a cost-effective, incremental backup mechanism that enables rapid recovery of the VM in case of failure. Snapshots capture point-in-time copies of the disk and can be used to create a new managed disk or restore the VM quickly, meeting the recovery objective without the expense of maintaining a separate, always-on replica.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the VM's boot diagnostics to store logs in a storage account.
Why it's wrong here
Boot diagnostics help troubleshooting but do not enable recovery.
- ✓
Configure automated snapshots of the managed disk on a schedule.
Why this is correct
Snapshots are cheap and allow quick restoration.
- ✗
Deploy a second VM in a different region as a pilot light.
Why it's wrong here
Overkill and expensive for quick recovery.
- ✗
Attach the VM to multiple managed disks in an availability set.
Why it's wrong here
Not cost-effective and does not directly aid recovery.
