The answer is AWS Secrets Manager and AWS Systems Manager Parameter Store (SecureString). Both services enable central credential management and automatic rotation for RDS, but Secrets Manager is the only one with built-in, automated rotation policies for Amazon RDS databases, while Parameter Store can store credentials as SecureString parameters and integrate with custom rotation using Lambda. On the AWS Certified Database Specialty DBS-C01 exam, this distinction tests your understanding of where native automation ends and custom implementation begins—a common trap is assuming Parameter Store handles rotation natively, which it does not. Remember the memory tip: Secrets Manager “secretly rotates” for you, while Parameter Store “stores” but needs your own turn.
DBS-C01 Database Security Practice Question
This DBS-C01 practice question tests your understanding of database security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Which TWO AWS services can be used to centrally manage database credentials and automate rotation for Amazon RDS? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Secrets Manager
Options A and D are correct. AWS Secrets Manager and AWS Systems Manager Parameter Store (SecureString) can both store RDS credentials, but Secrets Manager has built-in rotation for RDS. Option B is wrong because IAM database authentication eliminates the need for credentials but does not store them. Option C is wrong because KMS manages encryption keys, not secrets. Option E is wrong because CloudHSM provides hardware security modules, not secret management.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
AWS Secrets Manager
Why this is correct
Secrets Manager can store and automatically rotate RDS credentials.
Related concept
Static NAT maps one inside address to one outside address.
✗
AWS Key Management Service (KMS)
Why it's wrong here
KMS manages encryption keys, not secrets.
✗
IAM database authentication
Why it's wrong here
IAM authentication avoids stored credentials but does not manage them.
✓
AWS Systems Manager Parameter Store
Why this is correct
Parameter Store can store SecureStrings, but rotation requires additional automation.
Related concept
Static NAT maps one inside address to one outside address.
✗
AWS CloudHSM
Why it's wrong here
CloudHSM is for hardware-based key storage.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DBS-C01 NAT questions on configuration and troubleshooting.
Database Security — This question tests Database Security — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: AWS Secrets Manager — Options A and D are correct. AWS Secrets Manager and AWS Systems Manager Parameter Store (SecureString) can both store RDS credentials, but Secrets Manager has built-in rotation for RDS. Option B is wrong because IAM database authentication eliminates the need for credentials but does not store them. Option C is wrong because KMS manages encryption keys, not secrets. Option E is wrong because CloudHSM provides hardware security modules, not secret management.
What should I do if I get this DBS-C01 question wrong?

What is the key concept behind this question?
Static NAT maps one inside address to one outside address.

Variation 1. A company wants to centrally manage database user credentials and rotate them automatically. The database is an Amazon RDS for MySQL instance. Which AWS service should be used?
easy
✓ A.AWS Secrets Manager
B.AWS CloudHSM
C.AWS Identity and Access Management (IAM)
D.AWS Systems Manager Parameter Store
Why A: Option C is correct because AWS Secrets Manager can rotate RDS database credentials automatically. Option A is wrong because Systems Manager Parameter Store can store secrets but does not automatically rotate RDS credentials. Option B is wrong because IAM controls access to AWS services, not database users. Option D is wrong because CloudHSM is for hardware-based key storage, not credential rotation.
