Amazon Exam DVA-C02 Topic 3 Question 37 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 37
Topic #: 3

A developer is creating an AWS Lambda function. The Lambda function needs an external library to connect to a third-party solution The external library is a collection of files with a total size of 100 MB The developer needs to make the external library available to the Lambda execution environment and reduce the Lambda package space

Which solution will meet these requirements with the LEAST operational overhead?

ACreate a Lambda layer to store the external library Configure the Lambda function to use the layer

BCreate an Amazon S3 bucket Upload the external library into the S3 bucket. Mount the S3 bucket folder in the Lambda function Import the library by using the proper folder in the mount point.

CLoad the external library to the Lambda function's /tmp directory during deployment of the Lambda package. Import the library from the /tmp directory.

DCreate an Amazon Elastic File System (Amazon EFS) volume. Upload the external library to the EFS volume Mount the EFS volume in the Lambda function. Import the library by using the proper folder in the mount point.

Show Suggested Answer

Suggested Answer: A

Lambda Layers:These are designed to package dependencies that you can share across functions.

How to Use:

Create a layer, upload your 100MB library as a zip.

Attach the layer to your function.

In your function code, import the library from the standard layer path.

Option D with EFS is an interesting choice, but it might be overkill for a 100MB library. Layers or S3 seem like more straightforward solutions to me.

A: I think option A with Lambda layers is the way to go. It's simple and efficient.

Option C looks tempting, but I'm worried about the potential performance impact of loading the library from the /tmp directory during deployment. Better to keep it separate in my opinion.

I'd go with Option B. Storing the library in S3 and mounting the folder in the Lambda function seems like a good way to keep things modular and maintainable.
