A developer is creating an ecommerce workflow in an AWS Step Functions state machine that includes a HTTP Task state. The task passes shipping information and order details to an endpoint.
The developer needs to test the workflow to confirm that the HTTP headers and body are correct and that the responses meet expectations.

• A.Use the TestState API to invoke only the HTTP Task. Set the inspection level to TRACE.
• B.Use the TestState API to invoke the state machine. Set the inspection level to DEBUG.
• C.Use the data flow simulator to invoke only the HTTP Task. View the request and response data.
• D.Change the log level of the state machine to ALL. Run the state machine.

A developer is using an AWS CloudFormation template to create a pipeline in AWS CodePipeline. The template creates an Amazon S3 bucket that the pipeline references in a source stage. The template also creates an AWS CodeBuild project for a build stage. The pipeline sends notifications to an Amazon SNS topic. Logs for the CodeBuild project are stored in Amazon CloudWatch Logs.
The company needs to ensure that the pipeline's artifacts are encrypted with an existing customer-managed AWS KMS key. The developer has granted the pipeline permissions to use the KMS key.
Which additional step will meet these requirements?

• A.Create an Amazon S3 gateway endpoint that the pipeline can access.
• B.In the CloudFormation template, use the KMS key to encrypt the logs in CloudWatch Logs.
• C.Apply an S3 bucket policy that ensures the pipeline sends only encrypted objects to the S3 bucket.
• D.Configure the notification topic to use the existing KMS key to enable encryption with the existing KMS key.

• B.Test the new AWS Lambda function by first tracing it m AWS X-Ray.
• C.Bundle the serverless application using a SAM package.

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?

• A.Package each Python library in its own .zip file archive. Deploy each Lambda function with its own copy of the library.
• B.Create a Lambda layer with the required Python library. Use the Lambda layer in both Lambda functions.
• C.Combine the two Lambda functions into one Lambda function. Deploy the Lambda function as a single .zip file archive.
• D.Download the Python library to an S3 bucket. Program the Lambda functions to reference the object URLs.

A company had an Amazon RDS for MySQL DB instance that was named mysql-db. The DB instance was deleted within the past 90 days. A developer needs to find which 1AM user or role deleted the DB instance in the AWS environment. Which solution will provide this information?

• A.Retrieve the AWS CloudTrail events for the resource mysql-db where the event name is DeleteDBInstance. Inspect each event.
• B.Retrieve the Amazon CloudWatch log events from the most recent log stream within the rds/mysql-db log group. Inspect the log events.
• C.Retrieve the AWS X-Ray trace summaries. Filter by services with the name mysql-db. Inspect the ErrorRootCauses values within each summary.
• D.Retrieve the AWS Systems Manager deletions inventory Filter the inventory by deletions that have a TypeName value of RDS. Inspect the deletion details.
