- A
Restore only the affected table from the latest snapshot and keep the current cluster online.
Why wrong: Aurora recovery is not normally done by selectively merging a single table back into the live cluster. That approach is risky, slow, and difficult to validate after a schema-level or data-level corruption event.
- B
Perform a point-in-time restore to a new DB cluster or instance using automated backups.
Point-in-time restore is the supported mechanism for recovering to a specific timestamp before the corruption occurred. It uses automated backups and transaction logs to recreate a clean copy of the database state.
- C
Reboot the writer so Aurora automatically rolls back the bad migration.
Why wrong: A reboot does not undo committed database changes. Once the migration is written, restarting the writer will not reverse the corruption.
- D
Validate the restored database, then repoint the application or DNS name to the restored endpoint.
A PITR restore creates a new cluster or instance, so the application must be cut over to the recovered endpoint after validation. Repointing the application or DNS completes the recovery workflow and returns traffic to the clean database.
- E
Promote a read replica from the same cluster without restoring from backup.
Why wrong: Promoting a replica changes the primary writer, but it does not rewind the data to a point in time before the bad migration. It would promote the same corrupted data set unless a restore is performed first.
SAA-C03 Design Resilient Architectures Practice Question
This SAA-C03 practice question tests your understanding of design resilient architectures. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 production Amazon Aurora MySQL database is corrupted by a bad migration at 10:30 UTC, and the problem is discovered at 10:45 UTC. The team wants to recover to the state just before the migration with minimal manual effort. Which two actions should they take? Select two.
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
Perform a point-in-time restore to a new DB cluster or instance using automated backups.
Option B is correct because Amazon Aurora supports point-in-time recovery (PITR) to any point within the backup retention window, allowing you to restore the database to a state just before the migration (e.g., 10:29 UTC). This uses automated backups and requires minimal manual effort, as you simply specify the target time and a new DB cluster is created.
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.
- ✗
Restore only the affected table from the latest snapshot and keep the current cluster online.
Why it's wrong here
Aurora recovery is not normally done by selectively merging a single table back into the live cluster. That approach is risky, slow, and difficult to validate after a schema-level or data-level corruption event.
- ✓
Perform a point-in-time restore to a new DB cluster or instance using automated backups.
Why this is correct
Point-in-time restore is the supported mechanism for recovering to a specific timestamp before the corruption occurred. It uses automated backups and transaction logs to recreate a clean copy of the database state.

- ✓

Why this is correct
A PITR restore creates a new cluster or instance, so the application must be cut over to the recovered endpoint after validation. Repointing the application or DNS completes the recovery workflow and returns traffic to the clean database.

- ✗
Promote a read replica from the same cluster without restoring from backup.
Why it's wrong here
Promoting a replica changes the primary writer, but it does not rewind the data to a point in time before the bad migration. It would promote the same corrupted data set unless a restore is performed first.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think rebooting or promoting a replica can undo data changes, but these actions do not affect committed transactions; only a point-in-time restore can recover to a pre-migration state.
Detailed technical explanation
How to think about this question
Aurora's point-in-time restore works by replaying redo logs from automated backups to the specified timestamp, creating a new, independent cluster. The backup retention window defaults to 1 day but can be configured up to 35 days, and the restore operation is fully managed by AWS, requiring no manual log shipping. In a real-world scenario, you would also need to validate the restored data (Option D) before redirecting traffic to avoid serving corrupted data.
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.
