Full question →mediummultiple choiceObjective-mapped
A team runs an application on Amazon EC2 that connects to an Aurora database. The database password must rotate automatically every 30 days, and the application should retrieve the current secret at runtime using an IAM role. Which AWS service is the best fit?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
AWS Systems Manager Parameter Store standard parameters.
Parameter Store is useful for configuration values, but it does not provide built-in secret rotation in the same way.
B
Best answer
AWS Secrets Manager with rotation enabled.
Secrets Manager is designed for secure secret storage with built-in rotation support and fine-grained access through IAM. In this case, the application can retrieve the current database credentials at runtime with its EC2 role, while the secret is rotated on a schedule without embedding passwords in code. This reduces operational risk, improves auditability, and avoids manual password changes that often cause outages.
C
Distractor review
AWS KMS, because KMS stores credentials and rotates them automatically.
KMS protects encryption keys, but it is not a general secret store for application database credentials.
D
Distractor review
Amazon S3 with server-side encryption and versioning.
S3 can store files securely, but it is not the right service for application secret retrieval and automatic rotation.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
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 with rotation enabled. — Secrets Manager is purpose-built for rotating and retrieving application secrets such as database credentials. It integrates with IAM for runtime access, supports rotation workflows, and avoids hardcoding passwords in code or configuration files. For an Aurora connection password that changes regularly, Secrets Manager provides the most direct, manageable, and secure design with minimal application changes. Why others are wrong: Parameter Store is a valid place for configuration, but rotation is not its core capability. KMS protects keys, not user secrets like database passwords. S3 can store encrypted objects, but that adds unnecessary complexity and does not provide native secret rotation or runtime retrieval patterns for applications.
