The correct answer is to delete older automated backups that are no longer needed. This works because Amazon RDS for MySQL stores automated backups in the same allocated storage as the DB instance, so removing outdated backup files immediately reclaims that space without disabling the ongoing backup capability. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding of how automated backup storage is billed and managed—specifically that it counts against the instance’s provisioned storage, unlike manual snapshots which are stored separately in Amazon S3. A common trap is thinking that lowering the backup retention period frees space instantly, but that change only affects future backups, not existing ones. Another trap is confusing manual snapshots with automated backups; manual snapshots do not consume instance storage. Remember the key distinction: automated backups live on the instance volume, manual snapshots live in S3. For a quick memory tip, think “auto eats instance space, manual is S3-safe.”
DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. 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.
A database specialist is troubleshooting an Amazon RDS for MySQL DB instance that is running out of storage. The instance has automated backups enabled. The specialist needs to free up storage space immediately without losing backup capability. Which action should the specialist take?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Delete older automated backups that are no longer needed.
Option C is correct because deleting old automated backups frees up storage space without affecting the current backup capability. Option A is wrong because modifying the backup retention period does not free space immediately. Option B is wrong because manual snapshots are stored in Amazon S3 and do not affect the DB instance storage. Option D is wrong because disabling backups would stop future backups.
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.
✗
Modify the DB instance to reduce the backup retention period to 0 days.
Why it's wrong here
Reducing to 0 disables backups, which may not be desired.
✓
Delete older automated backups that are no longer needed.
Why this is correct
Automated backups consume DB instance storage; deleting old ones frees space.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Delete manual snapshots from the RDS console.
Why it's wrong here
Manual snapshots are stored separately and do not free DB instance storage.
✗
Disable automated backups to stop storage consumption.
Why it's wrong here
Disabling backups stops future backups but does not free existing storage.

→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.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
