NEW QUESTION # 233
A developer is working on an application that will be deployed on AWS. The developer needs to test and debug the code locally. The code is packaged and stored in an Amazon S3 bucket.
How can the developer test and debug the code locally with the LEAST amount of configuration?

Answer: A


NEW QUESTION # 234
A developer previously deployed an AWS Lambda function as a .zip package. The developer needs to deploy the Lambda function as a container. What steps should the developer take to accomplish this?

Answer: D

Explanation:
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.


NEW QUESTION # 235
An Amazon Simple Queue Service (Amazon SQS) queue serves as an event source for an AWS Lambda function. In the SQS queue, each item corresponds to a video file that the Lambda function must convert to a smaller resolution. The Lambda function is timing out on longer video files, but the Lambda function's timeout is already configured to its maximum value.
What should a developer do to avoid the timeouts without additional code changes?

Answer: C


NEW QUESTION # 236
A company uses an AWS Lambda function that reads messages from an Amazon Simple Queue Service (Amazon SQS) standard queue. The Lambda function makes an HTTP call to a third- party API for each message. The company wants to ensure that the Lambda function does not overwhelm the third-party API with more than two concurrent requests.
Which solution will meet these requirements?

Answer: D
