- A
Enable Performance Insights on the source cluster and export the data to S3.
Why wrong: Option C is incorrect: Performance Insights is for performance monitoring, not audit logging.
- B
Create an Aurora MySQL read replica and enable audit logs on the replica, then migrate from the replica.
Why wrong: Option D is incorrect: This does not capture audit logs from the source database.
- C
Use AWS CloudTrail to capture SQL queries and deliver them to S3.
Why wrong: Option A is incorrect: CloudTrail does not capture database audit logs; it captures AWS API calls.
- D
Enable the Aurora MySQL advanced audit feature with file-based output, and configure the DMS task to use these log files as a source for ongoing replication.
Option B is correct: This captures audit logs in files that DMS can process, ensuring continuity.
DBS-C01 Database Security Practice Question
This DBS-C01 practice question tests your understanding of database security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company runs an e-commerce application on AWS using an Aurora MySQL database cluster. The security team mandates that all database audit logs must be stored in Amazon S3 for at least one year for compliance. The database is currently configured to publish audit logs to Amazon CloudWatch Logs. The security team wants to use AWS Database Migration Service (DMS) to migrate the database to a new Aurora MySQL cluster, and during the migration, the audit logs must continue to be captured uninterrupted. Which solution meets these requirements with the LEAST operational overhead?

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 the Aurora MySQL advanced audit feature with file-based output, and configure the DMS task to use these log files as a source for ongoing replication.
Option D is correct because the Aurora MySQL advanced audit feature can output audit logs directly to files on the DB instance, and DMS can be configured to read these files as a source for ongoing replication. This ensures that audit logs are continuously captured and stored in S3 (via file-based output or subsequent upload) without interruption during the migration, minimizing operational overhead by avoiding additional services or manual log forwarding.
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 confuse CloudTrail (which logs AWS API calls) with database-level audit logging, or assume that a read replica can seamlessly inherit and forward audit logs from the source, when in fact it only logs its own activity.
Detailed technical explanation
How to think about this question
The Aurora MySQL advanced audit feature writes audit records to log files (e.g., /rdsdbdata/log/audit/) using the MySQL audit plugin, which can be configured to output in JSON or CSV format. DMS can use these files as a source for ongoing replication by specifying the 'aurora-advanced-audit' endpoint type, allowing continuous capture of audit events without relying on CloudWatch Logs or interrupting the migration process. This approach is particularly useful in regulated environments where audit continuity is critical during database migrations.
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 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.
