Quick Answer

The answer is to create a custom Lambda function with rotation logic, attach an IAM role granting it permissions to read and update the secret, and configure Secrets Manager to invoke that function on a 30-day schedule. This is correct because Secrets Manager does not include a built-in rotation template for database credentials; you must supply your own Lambda that handles the full rotation workflow—querying the database, generating new credentials, and updating the secret. On the AWS Certified Developer Associate DVA-C02 exam, this scenario tests your understanding that rotation is a Lambda-driven process, not an automatic Secrets Manager feature, and that the IAM role must be attached to the Lambda function, not to a user, to avoid direct secret exposure. A common trap is assuming Secrets Manager can rotate any secret natively, but it only provides templates for RDS and a few other services. Memory tip: "Lambda rotates, IAM gates, Secrets invokes."

DVA-C02 Security Practice Question

This DVA-C02 practice question tests your understanding of 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 uses AWS Secrets Manager to store database credentials. The credentials must be automatically rotated every 30 days. The developer needs to configure rotation without exposing the secret to any IAM user directly. Which configuration steps should the developer take?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Create a Lambda function with rotation logic, attach an IAM role with permissions to read and update the secret, and configure Secrets Manager to invoke the function every 30 days.

Option B is correct because AWS Secrets Manager does not provide a built-in Lambda function for rotating database credentials; you must create your own Lambda function that contains the rotation logic (e.g., querying the database, creating a new credential, and updating the secret). The Lambda function must be attached to an IAM role with permissions to read and update the secret, and Secrets Manager invokes this function based on the rotation schedule (every 30 days). This ensures the secret is never exposed directly to any IAM user, as only the Lambda function interacts with the secret programmatically.

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.

  • ✗

    Enable automatic rotation and choose a rotation interval of 30 days. Secrets Manager will automatically rotate the secret using a built-in Lambda function.

    Why it's wrong here

    Secrets Manager requires a Lambda function to perform rotation; there is no built-in function for all secret types. The developer must provide or configure a rotation function.

  • ✓

    Create a Lambda function with rotation logic, attach an IAM role with permissions to read and update the secret, and configure Secrets Manager to invoke the function every 30 days.

    Why this is correct

    This is the correct approach. The Lambda function handles the rotation, and the execution role must have 'secretsmanager:GetSecretValue' and 'secretsmanager:PutSecretValue' permissions for the specific secret.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Use AWS Certificate Manager (ACM) to rotate the secret automatically every 30 days.

    Why it's wrong here

    ACM is for SSL/TLS certificates, not for database credentials.

  • ✗

    Store the secret in AWS Systems Manager Parameter Store and set a schedule to rotate it using a CloudWatch Events rule.

    Why it's wrong here

    While Parameter Store can store secrets, it does not have built-in rotation capabilities like Secrets Manager. The question specifies using Secrets Manager.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates assume Secrets Manager provides a built-in Lambda function for all secret types, but in reality, you must create your own Lambda function for database credentials, while only AWS-managed secrets (like RDS) have pre-built rotation templates.

Detailed technical explanation

How to think about this question

Under the hood, Secrets Manager rotation works by invoking a custom Lambda function via a CloudWatch Events rule (or direct invocation) that follows a specific protocol: it creates a pending version of the secret, tests the new credentials, and then marks them as current. The Lambda function must have an IAM role with permissions like `secretsmanager:GetSecretValue`, `secretsmanager:PutSecretValue`, and `secretsmanager:UpdateSecretVersionStage`. A common real-world scenario is rotating RDS database credentials, where the Lambda function connects to the database using the current secret, creates a new user/password, and updates the secret in Secrets Manager.

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.

TExam Day Tips

  • 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.
