A developer is building an application that uses AWS API Gateway APIs, AWS Lambda functions, and AWS DynamoDB tables. The developer uses the AWS Serverless Application Model (AWS SAM) to build and run serverless applications on AWS. Each time the developer pushes changes for only to the Lambda functions, all the artifacts in the application are rebuilt.
The developer wants to implement AWS SAM Accelerate by running a command to only redeploy the Lambda functions that have changed.
Which command will meet these requirements?

  1. sam deploy --force-upload
  2. sam deploy --no-execute-changeset
  3. sam package
  4. sam sync --watch

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?

  1. Add an AWS Secrets Manager GenerateSecretString resource to the CloudFormation template. Set the value to reference new credentials for the CloudFormation resource.
  2. 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.
  3. 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.
  4. 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.

Answer(s): B



A developer is trying to get data from an Amazon DynamoDB table called demoman-table. The developer configured the AWS CLI to use a specific IAM user’s credentials and ran the following command:
aws dynamodb get-item --table-name demoman-table --key '{"id": {"N":"1993"}}'
The command returned errors and no rows were returned.
What is the MOST likely cause of these issues?

  1. The command is incorrect; it should be rewritten to use put-item with a string argument.
  2. The developer needs to log a ticket with AWS Support to enable access to the demoman-table.
  3. Amazon DynamoDB cannot be accessed from the AWS CLI and needs to be called via the REST API.
  4. The IAM user needs an associated policy with read access to demoman-table.

Answer(s): D
