Discuss Amazon DVA-C02 Exam Topic 1 Question 64

A developer previously deployed an AWS Lambda function as a .zip package. The developer needs to deploy the Lambda function as a container.

ACreate an Amazon ECR repository in the same AWS Region as the Lambda function. Package the Lambda function into a container image. Build the image and upload it to the Amazon ECR repository. Update the existing Lambda function configuration to specify the repository URI and container image tag.

BCreate an AWS SAM template that defines the Lambda function and its resources as code. Include a container image in the template, and store the container image in an Amazon S3 bucket. Deploy the AWS SAM template. Specify the S3 bucket URI.

CCreate an AWS CloudFormation template that defines the Lambda function and its resources as code. Include a container image in the template, and store the image in an Amazon S3 bucket. Deploy the CloudFormation template. Specify the S3 bucket URI.

DCreate an Amazon ECR repository in the same AWS Region as the Lambda function. Build the image and upload it to the Amazon ECR repository. Update the existing Lambda function to use the new image by specifying the repository URI.

Suggested Answer: A

Why Option A is Correct:Converting a Lambda function to use a container image involves packaging the function code into a container image, storing the image in Amazon Elastic Container Registry (ECR), and updating the function to use the ECR repository URI.

Why Other Options are Incorrect:

Option B: SAM templates support container-based Lambda deployment, but storing the image in S3 is not applicable.

Option C: CloudFormation does not natively support specifying Lambda container images in S3.

Option D: While partially correct, it omits the need to specify the image tag for the deployment.

Maybe suggested answer is not correct because the tricky part is updating the function to use a container image and including the image tag.

Rex

Agreed, but D saves time on deployment.

Adelle 5 days ago

D is good too, but A feels more complete.

Rex 10 days ago

I like option D. Simple and direct.

Carin 15 days ago

Still, it keeps everything organized in one template.

Teri 21 days ago

True, but B involves S3, which adds complexity.

Carin 26 days ago

I prefer option B. SAM templates are great for infrastructure as code.

Adelle 1 month ago

Plus, updating the Lambda config is straightforward.

Teri 1 month ago

Yeah, A makes sense. ECR is perfect for containers.

Adelle 1 month ago

I think option A is the best choice.

Wilda 2 months ago

I still think B is the most organized approach.

Val 2 months ago

Right, D might miss some best practices.

Nadine 2 months ago

D is too simple. It skips the packaging step.

Wilda 2 months ago

I get that, but CloudFormation is powerful for larger projects.

Val 2 months ago

C is also good, but I feel it’s overkill for this task.

Nadine 2 months ago

True, but B requires S3, which adds complexity.

Wilda 3 months ago

I prefer option B. SAM templates are great for infrastructure as code.

Val 3 months ago

Yeah, A makes sense. ECR is perfect for containers.

Nadine 3 months ago

I think option A is the best choice.

Truman 3 months ago

C seems a bit overkill for this task, don’t you think?

Gilma 3 months ago

Totally agree with A, ECR is the way to go!

Marge 4 months ago

Wait, can you really store container images in S3?

Josefa 4 months ago

I think B is better for managing resources as code.

Ulysses 4 months ago

Option A is the most straightforward approach.

Ashton 4 months ago

Option D sounds straightforward since it mentions updating the Lambda function directly with the ECR repository URI. I think that’s the most efficient way, but I’m not entirely sure if it covers everything needed for deployment.

Shonda 6 months ago

I feel like option C is similar to what we did with CloudFormation templates, but I don’t recall if we ever stored images in S3. That part seems a bit off to me.

Angella 6 months ago

I think option B mentions AWS SAM, which we practiced in class. It’s supposed to help with defining resources as code, but I’m not clear on how it handles container images.

Truman 6 months ago

I remember we talked about using Amazon ECR for storing container images, so option A seems familiar. But I'm not sure if it’s the only way to deploy a Lambda function as a container.
