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 capture serial console output and screenshots for troubleshooting boot failures; they do not create a recoverable copy of the VM or its managed disk. Enabling boot diagnostics is the right step when diagnosing why a VM fails to start, not for rapid recovery after failure.
- ✓
Configure automated snapshots of the managed disk on a schedule.
Why this is correct
Scheduled automated snapshots capture point-in-time copies of the managed disk, enabling rapid restoration after failure or corruption. Snapshots are incremental and cheap, meeting the recovery objective at minimal cost, unlike continuous replication or a full standby VM.
- ✗
Deploy a second VM in a different region as a pilot light.
Why it's wrong here
A pilot light in another region duplicates compute and storage continuously, incurring ongoing cost that exceeds the minimal-cost objective; recovery here needs a disk-level copy, not a running standby. Pilot light suits scenarios demanding cross-region disaster recovery with low RTO where budget permits duplication.
- ✗
Attach the VM to multiple managed disks in an availability set.
Why it's wrong here
Availability sets protect against host and rack failures by distributing VMs, but attaching multiple managed disks to one VM provides no recovery mechanism and managed disks cannot be attached to multiple VMs concurrently. Availability sets are correct when running several VMs that must survive a single hardware fault.
