The answer is to enable the database engine audit logs, also known as advanced auditing, for Amazon Aurora MySQL. This feature is correct because it directly captures all SQL statements executed by database users at the engine level, providing a granular, query-specific audit trail that meets compliance and security requirements. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between AWS services that log different layers of activity—CloudTrail records API calls, Enhanced Monitoring tracks OS metrics, and Database Activity Streams offer near-real-time monitoring, but only advanced auditing logs the actual SQL queries. A common trap is confusing Database Activity Streams with SQL audit logging; while they can monitor activity, they are not the primary feature for capturing executed SQL statements. Memory tip: think "SQL audit = engine audit," not API or OS logs.
DBS-C01 Database Security Practice Question
This DBS-C01 practice question tests your understanding of database security. 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 company uses Amazon Aurora MySQL-Compatible Edition and needs to audit all SQL statements executed by database users. Which feature should be enabled?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable the database engine audit logs (advanced auditing).
Option A is correct because Aurora MySQL supports advanced auditing through database engine audit logs. Option B is wrong because CloudTrail logs API calls, not SQL queries. Option C is wrong because RDS Enhanced Monitoring provides OS metrics, not SQL audit. Option D is wrong because database activity streams capture activity in near real-time but are designed for monitoring and not primarily for SQL audit logging; however, they can be used, but the most direct answer is advanced auditing.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Enable the database engine audit logs (advanced auditing).
Why this is correct
Aurora MySQL can log SQL statements using the audit plugin.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable AWS CloudTrail data events for the DB instance.
Why it's wrong here
CloudTrail does not log SQL queries.
✗
Enable database activity streams.
Why it's wrong here
Database activity streams capture activity but are more focused on monitoring; advanced auditing is the standard for SQL audit.
✗
Enable RDS Enhanced Monitoring.
Why it's wrong here
Enhanced Monitoring provides OS-level metrics, not SQL audit.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DBS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Enable the database engine audit logs (advanced auditing). — Option A is correct because Aurora MySQL supports advanced auditing through database engine audit logs. Option B is wrong because CloudTrail logs API calls, not SQL queries. Option C is wrong because RDS Enhanced Monitoring provides OS metrics, not SQL audit. Option D is wrong because database activity streams capture activity in near real-time but are designed for monitoring and not primarily for SQL audit logging; however, they can be used, but the most direct answer is advanced auditing.
