Question 60

A company is building a serverless application that uses AWS Lambda functions. The company needs to create a set of test events to test Lambda functions in a development environment. The test events will be created once and then will be used by all the developers in an 1AM developer group. The test events must be editable by any of the 1AM users in the 1AM developer group.

Which solution will meet these requirements?

Options:

Create and store the test events in Amazon S3 as JSON objects. Allow S3 bucket access to all 1AM users.

Create the test events. Configure the event sharing settings to make the test events shareable.

Create and store the test events in Amazon DynamoDB. Allow access to DynamoDB by using 1AM roles.

Create the test events. Configure the event sharing settings to make the test events private.

Question 61

A developer is designing a serverless application with two AWS Lambda functions to process photos. One Lambda function stores objects in an Amazon S3 bucket and stores the associated metadata in an Amazon DynamoDB table. The other Lambda function fetches the objects from the S3 bucket by using the metadata from the DynamoDB table. Both Lambda functions use the same Python library to perform complex computations and are approaching the quota for the maximum size of zipped deployment packages.

What should the developer do to reduce the size of the Lambda deployment packages with the LEAST operational overhead?

Options:

Package each Python library in its own .zip file archive. Deploy each Lambda function with its own copy of the library.

Create a Lambda layer with the required Python library. Use the Lambda layer in both Lambda functions.

Combine the two Lambda functions into one Lambda function. Deploy the Lambda function as a single .zip file archive.

Download the Python library to an S3 bucket. Program the Lambda functions to reference the object URLs.

Question 62

A developer is writing unit tests tor a new application that will be deployed on AWS. The developer wants to validate all pull requests with unit tests and merge the code with the main branch only when all tests pass

The developer stores the code in AWS CodeCommit and sets up AWS CodeBuild to run the unit tests. The developer creates an AWS Lambda function to start the CodeBuild task. The developer needs to identify the CodeCommit events in an Amazon EventBridge event that can invoke the Lambda function when a pull request is created or updated.

Which CodeCommit event will meet these requirements?

Question 63

An application ingests data from an Amazon Kinesis data stream. The shards in the data stream are set for normal traffic.

During tests for peak traffic, the application ingests data slowly. A developer needs to adjust the data stream to handle the peak traffic.

What should the developer do to meet this requirement MOST cost-effectively?

Options:

Install the Kinesis Producer Library {KPL) to ingest data into the data stream.

Switch to on-demand capacity mode for the data stream. Specify a partition key when writing data to the data stream.

Decrease the amount of time that data is kept in the data stream by using the DecreaseStreamRetention Period API operation.

Increase the shard count in the data stream by using the UpdateShardCount API operation.
