A developer is creating an AWS Lambda function that searches for items from an
Amazon DynamoDB table that contains customer contact information. The DynamoDB table items have the customer’s email_address as the partition key and additional properties such as customer_type, name and job_title.
The Lambda function runs whenever a user types a new character into the customer_type text input. The developer wants the search to return partial matches of all the email_address property of a particular customer_type. The developer does not want to recreate the DynamoDB table.
What should the developer do to meet these requirements?

  1. Add a global secondary index (GSI) to the DynamoDB table with customer_type as the partition key and email_address as the sort key. Perform a query operation on the GSI by using the begins_with key condition expression with the email_address property.
  2. Add a global secondary index (GSI) to the DynamoDB table with email_address as the partition key and customer_type as the sort key. Perform a query operation on the GSI by using the begins_with key condition expression with the email_address property.
  3. Add a local secondary index (LSI) to the DynamoDB table with customer_type as the partition key and email_address as the sort key. Perform a query operation on the LSI by using the begins_with key condition expression with the email_address property.
  4. Add a local secondary index (LSI) to the DynamoDB table with job_title as the partition key and email_address as the sort key. Perform a query operation on the LSI by using the begins_with key condition expression with the email_address property.

Answer(s): A



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

Answer(s): D



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.
