- A
Set log_statement = 'all' and log_min_duration_statement = 0 in the DB parameter group. Enable CloudWatch Logs export.
log_statement = 'all' logs all statements, and log_min_duration_statement = 0 ensures all durations are logged, so all queries appear in the logs.
- B
Install the pgAudit extension and configure it to log all statements. Enable CloudWatch Logs export in the RDS console.
Why wrong: pgAudit is for audit logging, not general query logging, and is more complex than needed.
- C
Set the parameter log_statement = 'ddl' in the DB parameter group. Enable CloudWatch Logs export.
Why wrong: log_statement = 'ddl' only logs DDL statements (CREATE, ALTER, DROP), not SELECT queries.
- D
Set log_min_duration_statement = -1 in the DB parameter group. Enable CloudWatch Logs export.
Why wrong: A value of -1 disables logging of statement durations, but does not enable logging of all statements.
Quick Answer
The correct answer is to set `log_statement = 'all'` and `log_min_duration_statement = 0` in the DB parameter group, then enable CloudWatch Logs export. This configuration works because `log_statement = 'all'` captures every SQL command including SELECT statements, while `log_min_duration_statement = 0` ensures no query is filtered out by duration thresholds—together they force PostgreSQL to write every query to its log output, which RDS then streams to CloudWatch Logs. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding of PostgreSQL logging parameters versus audit extensions; a common trap is confusing pgAudit (which creates separate audit logs) with the general query log, or thinking `log_min_duration_statement = -1` disables logging entirely. Remember the memory tip: "All queries, zero delay" — `log_statement = 'all'` plus `log_min_duration_statement = 0` means every statement is logged immediately, no exceptions.
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 financial services company runs a critical application on Amazon RDS for PostgreSQL. They must ensure that database activity logs are sent to Amazon CloudWatch Logs for real-time monitoring. The logs must include all SQL queries, including SELECT statements. Which configuration will meet these requirements?
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
Set log_statement = 'all' and log_min_duration_statement = 0 in the DB parameter group. Enable CloudWatch Logs export.
Option D is correct because to log all SQL queries including SELECT statements, you need to set the RDS parameter group parameters log_statement = 'all' and log_min_duration_statement = 0, and then enable exporting logs to CloudWatch Logs in the RDS console. Option A is wrong because pgAudit is needed if you want audit logs, but the requirement is for general query logs. Option B is wrong because setting log_statement = 'ddl' only logs DDL statements, not SELECT. Option C is wrong because log_min_duration_statement = -1 disables logging of all statements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set log_statement = 'all' and log_min_duration_statement = 0 in the DB parameter group. Enable CloudWatch Logs export.
Why this is correct
log_statement = 'all' logs all statements, and log_min_duration_statement = 0 ensures all durations are logged, so all queries appear in the logs.

- ✗
Install the pgAudit extension and configure it to log all statements. Enable CloudWatch Logs export in the RDS console.
Why it's wrong here
pgAudit is for audit logging, not general query logging, and is more complex than needed.
- ✗
Set the parameter log_statement = 'ddl' in the DB parameter group. Enable CloudWatch Logs export.
Why it's wrong here
log_statement = 'ddl' only logs DDL statements (CREATE, ALTER, DROP), not SELECT queries.
- ✗
Set log_min_duration_statement = -1 in the DB parameter group. Enable CloudWatch Logs export.
Why it's wrong here
A value of -1 disables logging of statement durations, but does not enable logging of all statements.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
