Question 8

A developer has designed an application to store incoming data as JSON files in Amazon S3 objects. Custom business logic in an AWS Lambda function then transforms the objects, and the Lambda function loads the data into an Amazon DynamoDB table. Recently, the workload has experienced sudden and significant changes in traffic. The flow of data to the DynamoDB table is becoming throttled.

The developer needs to implement a solution to eliminate the throttling and load the data into the DynamoDB table more consistently.

Which solution will meet these requirements?

Options:

Refactor the Lambda function into two functions. Configure one function to transform the data and one function to load the data into the DynamoDB table. Create an Amazon Simple Queue Service (Amazon SQS) queue in between the functions to hold the items as messages and to invoke the second function.

Turn on auto scaling for the DynamoDB table. Use Amazon CloudWatch to monitor the table's read and write capacity metrics and to track consumed capacity.

Create an alias for the Lambda function. Configure provisioned concurrency for the application to use.

Refactor the Lambda function into two functions. Configure one function to store the data in the DynamoDB table. Configure the second function to process the data and update the items after the data is stored in DynamoDB. Create a DynamoDB stream to invoke the second function after the data is

stored.

Question 9

A developer is building a microservices-based application by using Python on AWS and several AWS services The developer must use AWS X-Ray The developer views the service map by using the console to view the service dependencies.

Question 11

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.
