NEW QUESTION # 514
A developer is modifying an AWS Lambda function that accesses an Amazon RDS for MySQL database. The developer discovers that the Lambda function has the database credentials stored as plaintext in the Lambda function code.
The developer must implement a solution to make the credentials more secure. The solution must include automated credential rotation every 30 days.
Which solution will meet these requirements?

Answer: B

Explanation:
AWS Secrets Manager is designed to securely store and manage sensitive credentials. It provides built-in support for automated rotation (including every 30 days) and can integrate seamlessly with your Lambda function, eliminating the need to embed plaintext credentials in your code. This approach enhances security while reducing manual intervention.

Explanation:
Requirement Summary:
* DynamoDBProvisioned Mode
* ProvisionedThroughputExceededException error occurring
* App hosted on a smallburstable EC2 instance
Option A: Move to a larger EC2 instance
* #May improve local performance, butdoes not solve DynamoDB provisioned throughputlimits.
Option B: Increase DynamoDB RCUs
* #Valid: This directly increases theread throughputcapacity of the table.
* Helps handle more traffic andreduce throughput exceptions.
Option C: Reduce frequency via exponential backoff
* #Best practice: Usingexponential backoffandjitterreduces request pressure andspreads retriesout to avoid spiking.
Option D: Increase frequency of retries by reducing delay
* #Opposite of best practice. Increases load, worsening the issue.
Option E: Change to on-demand mode
* #Also validin general, but question is scoped around provisioned capacity.
* Sinceminimizing cost or workload typeisn't mentioned, andscaling the existing modelis the focus, prefer B and C.
