A company runs its databases on Amazon RDS for PostgreSQL. The company wants a secure solution to manage the master user password by rotating the password every 30 days. Which solution will meet these requirements with the LEAST operational overhead?

A.

Use Amazon EventBridge to schedule a custom AWS Lambda function to rotate the password every 30 days.

Answers
A.

Use Amazon EventBridge to schedule a custom AWS Lambda function to rotate the password every 30 days.

B.

Use the modlfy-db-instance command in the AWS CLI to change the password.

Answers

Use the modlfy-db-instance command in the AWS CLI to change the password.

C.

Integrate AWS Secrets Manager with Amazon RDS for PostgreSQL to automate password rotation.

Answers
C.

Integrate AWS Secrets Manager with Amazon RDS for PostgreSQL to automate password rotation.

D.

Integrate AWS Systems Manager Parameter Store with Amazon RDS for PostgreSQL to automate password rotation.

Answers
D.

Integrate AWS Systems Manager Parameter Store with Amazon RDS for PostgreSQL to automate password rotation.

Suggested answer: C

Explanation:

AWS Secrets Manager can integrate directly with Amazon RDS for automatic and seamless password rotation. Secrets Manager handles the complexity of password management, including generating strong passwords and rotating them at a defined interval (e.g., every 30 days). It also automatically updates the connection information for RDS, minimizing operational overhead.

Option A (Lambda with EventBridge): While possible, this requires custom coding and operational management of Lambda, which introduces additional complexity.

Option B (Manual password change): Using the modify-db-instance command requires manual intervention and is not automated, leading to more operational effort.

Option D (Parameter Store): Systems Manager Parameter Store is less specialized for password management than Secrets Manager and does not have built-in automated rotation for RDS credentials.
