CV0-004 Troubleshooting Practice Question
An automated snapshot of a cloud VM is failing with the error 'Quota exceeded for resource snapshots'. What is the most likely cause?
⚠ Common exam trap
CV0-004 often tests the distinction between quota limits and other snapshot failure causes, so candidates may confuse retention policies or disk space with the actual quota error.

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
✓
The maximum number of snapshots allowed has been reached.
The error 'Quota exceeded for resource snapshots' directly indicates that the cloud provider's limit on the number of snapshots for that resource (e.g., per volume, per region, or per account) has been reached. Cloud platforms enforce quotas to prevent resource exhaustion, and once the maximum count is hit, further snapshot creation fails until older snapshots are deleted or a quota increase is requested. This is a hard limit, not a transient condition like a backup window or disk fullness.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The snapshot is being created during a backup window.
Why it's wrong here
Snapshot quotas count stored snapshots, not the time of creation, so a backup window cannot trigger a quota error. Backup windows matter for scheduling and performance impact, and would be the right consideration when tuning when jobs run rather than diagnosing a hard quota limit.
- ✓
The maximum number of snapshots allowed has been reached.
Why this is correct
The subscription's snapshot quota has been exhausted, meaning the maximum number of snapshots permitted for that region or resource group is already allocated. The error explicitly names the quota for the snapshots resource, so the limit itself is the blocker. Deleting unused snapshots or requesting a quota increase resolves the failure.
- ✗
The snapshot retention policy is set too high.
Why it's wrong here
A high retention policy retains more snapshots, but the error names the quota limit itself, not the policy value; the quota is the ceiling, and retention merely consumes it. Retention tuning is the correct lever when snapshots accumulate unexpectedly within an adequate quota.
- ✗
The VM's disk is too full to create a snapshot.
Why it's wrong here
A full disk causes write failures, not a snapshots quota error; the message indicates the account's snapshot count or capacity limit has been reached. It is tempting because disk space commonly breaks snapshot creation, and would be the cause if the error reported insufficient free space instead.
