CV0-004 Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit. ``` [ERROR] Backup job failed at 2024-08-21 02:00:00. Reason: Volume snapshot creation timed out. Volume ID: vol-0a12345 Snapshot ID: snap-0b67890 ```
Refer to the exhibit. A cloud administrator sees this log after a nightly backup job. Which of the following is the most likely cause of the timeout?
⚠ Common exam trap
CompTIA Cloud+ often tests the misconception that a powered-off instance or missing backup agent is the root cause of snapshot timeouts, when in reality the most common cause is high I/O load on the volume during the snapshot operation.
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
✓
The volume has a high I/O load during the snapshot.
The log indicates a timeout during a nightly backup job that involves creating a snapshot. A high I/O load on the volume during the snapshot process can cause the snapshot to take longer than the configured timeout threshold, as the snapshot must capture a consistent point-in-time state while the volume is actively being written to. This is a common issue in cloud environments where the snapshot process competes for disk resources, leading to delays that exceed the timeout limit.
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 volume has a high I/O load during the snapshot.
Why this is correct
High I/O can slow snapshot creation and cause timeouts.
- ✗
The volume is attached to an instance that is powered off.
Why it's wrong here
A powered-off instance does not prevent snapshot creation.
- ✗
The snapshot target region is unreachable.
Why it's wrong here
The error indicates creation timeout, not transfer issue.
- ✗
The backup agent is not installed.
Why it's wrong here
Lack of backup agent would result in a different error, not a snapshot timeout.
