This CV0-004 practice question tests your understanding of operations and support. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization uses a cloud-based backup service to back up its critical database every night. The backup job has been failing for the past three days with an error message indicating 'insufficient storage space in the backup repository.' The administrator checks the backup repository and finds that it is 80% full. The database is 2 TB in size, and the backup policy retains 7 daily backups. The administrator estimates that each full backup is approximately 500 GB after deduplication. The company's RPO requirement is 24 hours. What should the administrator do to resolve the backup failure without violating the RPO?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Delete the oldest full backup that is more than 7 days old.
The backup repository is running out of space. Deleting older backups (beyond the current retention window) frees up space immediately, allowing the next backup to succeed and meet the 24-hour RPO. The retention policy is 7 days, so deleting backups older than 7 days or adjusting retention is appropriate.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Delete the oldest full backup that is more than 7 days old.
Why this is correct
This frees space while still keeping the required 7 days of backups, satisfying the RPO.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the backup retention period to 14 days to keep more backups.
Why it's wrong here
This would require even more storage and worsen the space issue.
✗
Enable incremental backups instead of full backups to reduce size.
Why it's wrong here
While this could help long-term, it does not immediately solve the current failure; also, initial full backup still needed.
✗
Reduce the deduplication ratio to lower storage usage.
Why it's wrong here
Deduplication ratio is not directly configurable and reducing it would increase storage usage.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
