DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. 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 needs to audit all SQL queries executed on an Amazon RDS for PostgreSQL instance. Which feature should the company enable?
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
✓
pgAudit extension
The correct answer is A because pgAudit (PostgreSQL Audit Extension) is the native, supported way to log all SQL queries on Amazon RDS for PostgreSQL. It provides detailed session and object audit logging via the shared_preload_libraries parameter, capturing every executed statement without requiring external tools or additional infrastructure.
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 confuse Database Activity Streams (a real RDS feature for streaming activity to Kinesis) with a full SQL audit log, but Database Activity Streams does not capture every SQL query in a traditional audit log format and requires additional processing, whereas pgAudit directly writes detailed SQL logs to the RDS log files.
Detailed technical explanation
How to think about this question
pgAudit works by hooking into PostgreSQL's logging subsystem via shared_preload_libraries and requires setting the pgaudit.log parameter to define what to log (e.g., READ, WRITE, FUNCTION, ROLE, DDL, MISC). In RDS, you must modify the custom DB parameter group to enable pgAudit, then create the extension in the database. A subtle behavior is that pgAudit logs at the session level by default, but you can also use object-level auditing for specific tables, which is critical for compliance with standards like PCI DSS or SOX.
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.
