- A
Enable automated backups with a retention period that covers the recovery window.
Point-in-time recovery in RDS depends on automated backups and transaction logs. The retention period must include the time before the corruption occurred, otherwise the desired recovery point will not be available.
- B
Perform a point-in-time restore to a new database instance.
Point-in-time restore lets you recover to a specific moment before the corruption. Restoring to a new instance avoids overwriting the damaged production database until the restored copy is validated.
- C
Convert the database to a single-AZ deployment for faster restores.
Why wrong: Single-AZ does not improve restoration from data corruption. It removes high availability and does not change the mechanics of point-in-time recovery.
- D
Delete the corrupted rows manually and continue without restoring.
Why wrong: Manual cleanup is error-prone and may miss related changes, orphaned rows, or application-level side effects. The requirement is to return to a known-good point in time, which restore achieves more reliably.
- E
Use a read replica as the only recovery source for all deletions.
Why wrong: A read replica is meant for read scaling and reporting, not as the primary mechanism for exact point-in-time recovery. It may not provide the precise recovery point needed for this incident.
SAA-C03 Design Resilient Architectures Practice Question
This SAA-C03 practice question tests your understanding of design resilient architectures. 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 developer accidentally corrupts part of a production Amazon RDS database, and the issue is discovered 45 minutes later. The team needs to restore the database to the state immediately before the change. Which two actions should be part of the recovery plan? Select two.
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 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
Enable automated backups with a retention period that covers the recovery window.
Option A is correct because automated backups must be enabled to allow point-in-time recovery (PITR) within the retention window. Since the corruption occurred 45 minutes ago, the retention period must cover at least that duration to restore to the state immediately before the change. Option B is correct because PITR restores the database to a specified time (down to the second) within the backup retention period, creating a new DB instance that reflects the state just before the corruption.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think a read replica can be used for point-in-time recovery, but it only provides read scaling and asynchronous replication, not a restore point before the corruption occurred.
Detailed technical explanation
How to think about this question
Point-in-time recovery in Amazon RDS uses automated backups and transaction logs to restore a DB instance to any second within the retention period, with a typical granularity of 5 minutes. The restore creates a new DB instance, leaving the original intact, which is critical for forensic analysis. In a real-world scenario, if automated backups were disabled, the only recovery option would be a manual snapshot taken before the corruption, which would not allow a precise 45-minute rollback.
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.
TExam Day Tips
- 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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
