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.
Network Topology
A security engineer runs the commands shown in the exhibit for an RDS MySQL DB instance. The engineer wants to enforce SSL connections to the database. What should the engineer do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a custom DB parameter group with require_secure_transport set to ON, associate it with the DB instance, and reboot the instance.
Option B is correct because the default parameter group is not modifiable; a custom parameter group must be created, require_secure_transport set to ON, and then associated with the DB instance, followed by a reboot. Option A is wrong because modifying the default parameter group is not allowed. Option C is wrong because modifying the DB instance directly does not change parameter group parameters. Option D is wrong because require_secure_transport is a MySQL-specific parameter, not an RDS API setting.
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.
✗
Modify the default.mysql8.0 parameter group to set require_secure_transport to ON and reboot the instance.
Why it's wrong here
Default parameter groups cannot be modified.
✗
Run the modify-db-instance command with --require-ssl-transport.
Why it's wrong here
There is no such parameter in the RDS API.
✓
Create a custom DB parameter group with require_secure_transport set to ON, associate it with the DB instance, and reboot the instance.
Read the scenario before looking for a memorised answer.
✗
Modify the DB instance and set the --enable-iam-database-authentication flag.
Why it's wrong here
IAM authentication requires SSL but does not enforce it directly.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
