A company is using the AWS Serverless Application Model (AWS SAM) to develop a social media application. A developer needs a quick way to test AWS Lambda functions locally by using test event payloads. The developer needs the structure of these test event payloads to match the actual events that AWS services create.

• A.Create shareable test Lambda events. Use these test Lambda events for local testing.
• B.Store manually created test event payloads locally. Use the sam local invoke command with the file path to the payloads.
• C.Store manually created test event payloads in an Amazon S3 bucket. Use the sam local invoke command with the S3 path to the payloads.
• D.Use the sam local generate-event command to create test payloads for local testing.

A company has an Amazon DynamoDB table that contains records of users that have signed up for a trial of the company's product. The company is using a spreadsheet to track data about the product trial. The company needs to ensure the spreadsheet is automatically updated with the latest information when individual trials begin, are updated, or finish.
Which solution will meet these requirements?

• A.Create a DynamoDB Accelerator (DAX) cluster from the table. Set the view type to new image.
  Create an AWS Lambda function that uses the cluster data to update the spreadsheet. Subscribe the Lambda function to the cluster.
• B.Create a DynamoDB Accelerator (DAX) cluster from the table. Set the view type to old image.
  Create an AWS Lambda function that uses the cluster data to update the spreadsheet. Subscribe the Lambda function to the cluster.
• C.Enable a DynamoDB stream for the table. Set the view type to old image. Create an AWS Lambda function that uses the stream data to update the spreadsheet. Subscribe the Lambda function to the stream.
• D.Enable a DynamoDB stream for the table. Set the view type to new image. Create an AWS Lambda function that uses the stream data to update the spreadsheet. Subscribe the Lambda function to the stream.

A developer is creating an application that will store personal health information (PHI). The PHI needs to be encrypted at all times. An encrypted Amazon RDS for MySQL DB instance is storing the dat a. The developer wants to increase the performance of the application by caching frequently accessed data while adding the ability to sort or rank the cached datasets.
Which solution will meet these requirements?

• A.Create an Amazon RDS for MySQL read replica. Connect to the read replica by using SSL. Configure the read replica to store frequently accessed data.
• B.Create an Amazon DynamoDB table and a DynamoDB Accelerator (DAX) cluster for the table. Store frequently accessed data in the DynamoDB table.
• C.Create an Amazon ElastiCache for Redis instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.
• D.Create an Amazon ElastiCache for Memcached instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.

A developer uses AWS CloudFormation to deploy an Amazon API Gateway API and an AWS Step Functions state machine The state machine must reference the API Gateway API after the CloudFormation template is deployed The developer needs a solution that uses the state machine to reference the API Gateway endpoint.
Which solution will meet these requirements MOST cost-effectively?

• A.Configure the CloudFormation template to reference the API endpoint in the DefinitionSubstitutions property for the AWS StepFunctions StateMachme resource.
• B.Configure the CloudFormation template to store the API endpoint in an environment variable for the AWS::StepFunctions::StateMachine resourc Configure the state machine to reference the environment variable
• C.Configure the CloudFormation template to store the API endpoint in a standard AWS: SecretsManager Secret resource Configure the state machine to reference the resource
• D.Configure the CloudFormation template to store the API endpoint in a standard AWS::AppConfig;:ConfigurationProfile resource Configure the state machine to reference

A developer is building an application that gives users the ability to view bank accounts from multiple sources in a single dashboard. The developer has automated the process to retrieve API credentials for these sources. The process invokes an AWS Lambda function that is associated with an AWS CloudFormation custom resource.
The developer wants a solution that will store the API credentials with minimal operational overhead.
Which solution will meet these requirements in the MOST secure way?

• A.Add an AWS Secrets Manager GenerateSecretString resource to the CloudFormation template.
  Set the value to reference new credentials for the CloudFormation resource.
• B.Use the AWS SDK ssm:PutParameter operation in the Lambda function from the existing custom resource to store the credentials as a parameter. Set the parameter value to reference the new credentials. Set the parameter type to SecureString.
• C.Add an AWS Systems Manager Parameter Store resource to the CloudFormation template. Set the CloudFormation resource value to reference the new credentials. Set the resource NoEcho attribute to true.
• D.Use the AWS SDK ssm:PutParameter operation in the Lambda function from the existing custom resource to store the credentials as a parameter. Set the parameter value to reference the new credentials. Set the parameter NoEcho attribute to true.
