Full question →mediummultiple choiceObjective-mapped
A company uses Amazon RDS with automated backups enabled (retention period: 7 days). At 10:30 UTC, a bad release corrupts specific rows in a production table. The team detects the issue at 11:10 UTC. They need to revert the database state to what it was from 10:00–10:30 UTC, recover quickly, and minimize risk to the currently running workload. What is the best option?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Reboot the DB instance and rely on the corrupted data being overwritten by storage-level changes.
Rebooting the DB instance does not undo logical data changes (for example, corrupted rows caused by an application release). It preserves the current database contents; it does not restore a previous state.
B
Best answer
Perform a point-in-time restore to a new DB instance using a timestamp before the corruption (for example, a time within 10:00–10:30 UTC).
With automated backups enabled, RDS supports point-in-time recovery (PITR) within the retention window. Restoring to a timestamp before the corruption creates a consistent copy from that moment. The team can validate the restored DB and then cut over application traffic, reducing risk to the currently running workload.
C
Distractor review
Restore only the most recent automated backup snapshot, even if it is after the corruption timestamp.
A “most recent snapshot” may have been taken after the corruption occurred. If the snapshot includes the corrupted rows, restoring it would not meet the requirement to revert to the 10:00–10:30 UTC state.
D
Distractor review
Create a read replica of the current DB instance and overwrite the corrupted table using SELECT queries from the replica.
A read replica continuously replicates from the source and will receive the corruption as well. It cannot recreate the pre-corruption data state needed for a time-based rollback.
Common exam trap
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.
Technical deep dive
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
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.

Questions learners often ask
What does this SAA-C03 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Perform a point-in-time restore to a new DB instance using a timestamp before the corruption (for example, a time within 10:00–10:30 UTC). — RDS automated backups enable point-in-time recovery (PITR) as long as the target timestamp falls within the retention window. Restoring to a timestamp before the corruption (within 10:00–10:30 UTC) produces a consistent database state for that time. Restoring to a new DB instance lets the team test and prepare the rollback copy before switching the application, which minimizes risk and disruption to the production workload while enabling a quick, time-accurate revert. Rebooting does not revert data modifications, so corruption would remain. Restoring a snapshot after the corruption may preserve the bad data and would not satisfy the required time range. A read replica replicates changes from the corrupted source, so it cannot provide a pre-corruption view.
