- D
Enable RDS Enhanced Monitoring.
Why wrong: Enhanced Monitoring does not log database connections.

Auditing Login Attempts in RDS PostgreSQL — rds.log_connections
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 is using Amazon RDS for PostgreSQL and needs to audit login attempts. Which configuration is required?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set rds.log_connections to 1 in the DB parameter group.
Setting the rds.log_connections parameter to 1 logs login attempts. Option A is correct. Option B is wrong because CloudTrail logs API calls, not database login attempts. Option C is wrong because security groups do not log connections; they only filter traffic. Option D is wrong because Enhanced Monitoring provides OS metrics, not login logs.
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
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

Same concept, more angles
1 more ways this is tested on DBS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company uses Amazon RDS for PostgreSQL and wants to audit all database login attempts. Which TWO services can be used together to achieve this?
medium- ✓ A.Enable AWS CloudTrail.
- B.Enable VPC Flow Logs.
- C.Enable S3 access logs to capture API calls.
- D.Enable RDS Enhanced Monitoring.
- ✓ E.Enable RDS for PostgreSQL to log to CloudWatch Logs.
Why A: To audit all database login attempts in RDS for PostgreSQL, you need to capture both the configuration changes (e.g., enabling audit logging) and the actual login events. AWS CloudTrail (Option A) records management API calls, such as modifying the DB parameter group to enable logging to CloudWatch Logs. Option E enables RDS for PostgreSQL to log login attempts directly to CloudWatch Logs. Together, they provide complete auditing: CloudTrail for the administrative actions and CloudWatch Logs for the login events. The other options do not capture login attempts.
