Amazon DVA-C02 Exam - 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.

Wait, can you really use EFS with Lambda? That sounds complicated.

I disagree, B could work too, especially for larger libraries.

EFS sounds like a good option for larger files, but I remember it can be more complex to set up. I wonder if the operational overhead is really the least with option D.

I vaguely recall that the /tmp directory has size limitations, so option C might not be ideal for a 100 MB library. It seems risky.

I'm not entirely sure, but I think using S3 could add more complexity than necessary. I feel like we practiced a similar question where layers were the answer.

I remember discussing Lambda layers in class, and I think they are designed specifically for this kind of situation. So, option A seems like the best choice.

I'm not sure about the performance implications of mounting an S3 bucket or EFS volume in the Lambda function. Option C with the /tmp directory might be the most efficient in terms of execution time.

I'm leaning towards Option D with the Amazon EFS volume. That way the library is stored in a separate, scalable storage system and can be easily accessed by the Lambda function.

Option A with the Lambda layer seems like the simplest and most straightforward solution. It keeps the library separate from the Lambda function code and should be easy to manage.

This looks like a pretty straightforward AWS Lambda question. I think the key is to find the solution that minimizes operational overhead while still meeting the requirements.

Hmm, I'm a bit confused about the different options here. I'm not sure which one would have the least operational overhead. I'll need to think this through carefully.

I think 3D privacy masking might refer to how the mask changes shape, like option B. I'm not entirely sure though.

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!

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.

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.
