Question #: 37
Topic #: 3
[All DVA-C02 Questions]

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?

Show Suggested Answer Hide 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.

Can you imagine if the developer just tried to include the entire 100MB library directly in the Lambda function's code? Talk about a bloated package!

I'm not sure, but I think option D could also work. Mounting an EFS volume in the Lambda function might be a good approach.

I agree with Staci. Using a Lambda layer seems like the most efficient way to handle the external library.

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.

C: Yeah, I think using the /tmp directory during deployment is a bit messy. Layers or S3 would be cleaner solutions.

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.

Option A seems like the easiest way to go. Layers are designed for this exact use case, and it should reduce the deployment package size.
