Amazon Exam DVA-C02 Topic 2 Question 40 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 40
Topic #: 2

A developer is creating an AWS Lambda function that consumes messages from an Amazon Simple Queue Service (Amazon SQS) standard queue. The developer notices that the Lambda function processes some messages multiple times.

How should developer resolve this issue MOST cost-effectively?

AChange the Amazon SQS standard queue to an Amazon SQS FIFO queue by using the Amazon SQS message deduplication ID.

BSet up a dead-letter queue.

CSet the maximum concurrency limit of the AWS Lambda function to 1

DChange the message processing to use Amazon Kinesis Data Streams instead of Amazon SQS.

Show Suggested Answer

Suggested Answer: D

AWS Secrets Manager:Built for managing secrets, providing encryption, automatic rotation, and access control.

Customer Master Key (CMK):Provides an extra layer of control over encryption through AWS KMS.

Automatic Rotation:Enhances security by regularly changing the secret.

User Data Script:Allows secrets retrieval at instance startup and sets them as environment variables for seamless use within the application.

Option D is an interesting idea, but using Kinesis Data Streams might be overkill for this use case. It could end up being more complex and expensive than necessary.

Limiting the concurrency to 1 in Option C might work, but it could impact the overall performance of the Lambda function. I'm not sure if it's the best approach.

I like the idea of setting up a dead-letter queue in Option B. That way we can identify and re-process the problematic messages.

But wouldn't setting the maximum concurrency limit of the Lambda function to 1 be a more cost-effective solution?

Option A seems like the easiest solution, but I'm not sure if it's the most cost-effective. FIFO queues can be more expensive than standard queues.
