A company is updating an application to move the backend of the application from Amazon EC2 instances to a serverless model. The application uses an Amazon RDS for MySQL DB instance and runs in a single VPC on AWS. The application and the DB instance are deployed in a private subnet in the VPC.
The company needs to connect AWS Lambda functions to the DB instance.
Which solution will meet these requirements?

  1. Create Lambda functions inside the VPC with the AWSLambdaBasicExecutionRole policy attached to the Lambda execution role. Modify the RDS security group to allow inbound access from the Lambda security group.
  2. Create Lambda functions inside the VPC with the AWSLambdaVPCAccessExecutionRole policy attached to the Lambda execution role. Modify the RDS security group to allow inbound access from the Lambda security group.
  3. Create Lambda functions with the AWSLambdaBasicExecutionRole policy attached to the Lambda execution role. Create an interface VPC endpoint for the Lambda functions. Configure the interface endpoint policy to allow the lambda:InvokeFunclion action for each Lambda function's Amazon Resource Name (ARN).
  4. Create Lambda functions with the AWSLambdaVPCAccessExecutionRole policy attached to the Lambda execution role. Create an interface VPC endpoint for the Lambda functions. Configure the interface endpoint policy to allow the lambda:InvokeFunction action for each Lambda function's Amazon Resource Name (ARN).

Answer(s): B



A company has a web application that runs on Amazon EC2 instances with a custom Amazon Machine Image (AMI). The company uses AWS CloudFormation to provision the application. The application runs in the us-east-1 Region, and the company needs to deploy the application to the us-west-1 Region.
An attempt to create the AWS CloudFormation stack in us-west-1 fails. An error message states that the AMI ID does not exist. A developer must resolve this error with a solution that uses the least amount of operational overhead.
Which solution meets these requirements?

  1. Change the AWS CloudFormation templates for us-east-1 and us-west-1 to use an AWS AMI. Relaunch the stack for both Regions.
  2. Copy the custom AMI from us-east-1 to us-west-1. Update the AWS CloudFormation template for us-west-1 to refer to AMI ID for the copied AMI. Relaunch the stack.
  3. Build the custom AMI in us-west-1. Create a new AWS CloudFormation template to launch the stack in us-west-1 with the new AMI ID.
  4. Manually deploy the application outside AWS CloudFormation in us-west-1.

Answer(s): B



A developer is updating several AWS Lambda functions and notices that all the Lambda functions share the same custom libraries. The developer wants to centralize all the libraries, update the libraries in a convenient way, and keep the libraries versioned.
Which solution will meet these requirements with the LEAST development effort?

  1. Create an AWS CodeArtifact repository that contains all the custom libraries.
  2. Create a custom container image for the Lambda functions to save all the custom libraries.
  3. Create a Lambda layer that contains all the custom libraries.
  4. Create an Amazon Elastic File System (Amazon EFS) file system to store all the custom libraries.

Answer(s): C



A developer wants to use AWS Elastic Beanstalk to test a new version of an application in a test environment.
Which deployment method offers the FASTEST deployment?

  1. Immutable
  2. Rolling
  3. Rolling with additional batch
  4. All at once

Answer(s): D



A company is providing read access to objects in an Amazon S3 bucket for different customers. The company uses IAM permissions to restrict access to the S3 bucket. The customers can access only their own files.
Due to a regulation requirement, the company needs to enforce encryption in transit for interactions with Amazon S3.
Which solution will meet these requirements?

  1. Add a bucket policy to the S3 bucket to deny S3 actions when the aws:SecureTransport condition is equal to false.
  2. Add a bucket policy to the S3 bucket to deny S3 actions when the s3:x-amz-acl condition is equal to public-read.
  3. Add an IAM policy to the IAM users to enforce the usage of the AWS SDK.
  4. Add an IAM policy to the IAM users that allows S3 actions when the s3:x-amz-acl condition is equal to bucket-owner-read.

Answer(s): A
