The answer is that the require_secure_transport parameter is not set to 1 in the DB parameter group. This parameter, when enabled, forces the RDS MySQL instance to reject any connection that does not use SSL/TLS, regardless of the client’s configuration. If the developer connects without specifying SSL options and the connection succeeds, it means the parameter is either set to 0 or has not been applied after a parameter group modification. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding that RDS parameter changes require a reboot to take effect for static parameters, and that require_secure_transport is a dynamic parameter but must be explicitly set to 1. A common trap is assuming the client’s default behavior is the issue, when the real culprit is the server-side enforcement flag. Memory tip: think of require_secure_transport as a bouncer—if the bouncer isn’t told to check IDs (set to 1), anyone can walk in without showing SSL credentials.
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 is using Amazon RDS for MySQL to power a web application. The database contains sensitive data, and the security team requires that all connections to the database use SSL/TLS. The team has enabled 'require_secure_transport' parameter in the DB parameter group. However, a developer reports that they are able to connect to the database using a MySQL client without specifying SSL options. What could be the reason?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The 'require_secure_transport' parameter is not set to '1' in the DB parameter group.
Option B is correct because RDS offers a '--ssl-mode' option in the MySQL client; if not specified, the client may use SSL by default if the server requires it. But the developer might be using an older client that defaults to non-SSL. The 'require_secure_transport' parameter in RDS forces SSL only for new connections; however, if the client does not request SSL, the server may still accept non-SSL if the parameter is not set correctly. Actually, the correct answer is that the parameter might not be set to '1'. Option B is the most plausible.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The RDS instance is configured to accept both SSL and non-SSL connections by default.
Why it's wrong here
With the parameter set correctly, non-SSL connections are rejected.
✗
The MySQL client automatically upgrades to SSL when the server requires it.
Why it's wrong here
The client must be configured to use SSL; it does not auto-upgrade.
✓
The 'require_secure_transport' parameter is not set to '1' in the DB parameter group.
Why this is correct
The parameter must be set to '1' to enforce SSL; otherwise, non-SSL connections are allowed.

✗
The developer is connecting from an EC2 instance in the same VPC, which bypasses SSL enforcement.
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.
