A software company is launching a multimedia application. The application will allow guest users to access sample content before the users decide if they want to create an account to gain full access. The company wants to implement an authentication process that can identify users who have already created an account. The company also needs to keep track of the number of guest users who eventually create an account.
Which combination of steps will meet these requirements? (Choose two.)

  1. Create an Amazon Cognito user pool. Configure the user pool to allow unauthenticated users. Exchange user tokens for temporary credentials that allow authenticated users to assume a role.
  2. Create an Amazon Cognito identity pool. Configure the identity pool to allow unauthenticated users. Exchange unique identity for temporary credentials that allow all users to assume a role.
  3. Create an Amazon CloudFront distribution. Configure the distribution to allow unauthenticated users. Exchange user tokens for temporary credentials that allow all users to assume a role.
  4. Create a role for authenticated users that allows access to all content. Create a role for unauthenticated users that allows access to only the sample content.
  5. Allow all users to access the sample content by default. Create a role for authenticated users that allows access to the other content.

Answer(s): B,D



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



A company has an image storage web application that runs on AWS. The company hosts the application on Amazon EC2 instances in an Auto Scaling group. The Auto Scaling group acts as the target group for an Application Load Balancer (ALB) and uses an Amazon S3 bucket to store the images for sale.
The company wants to develop a feature to test system requests. The feature will direct requests to a separate target group that hosts a new beta version of the application.
Which solution will meet this requirement with the LEAST effort?

  1. Create a new Auto Scaling group and target group for the beta version of the application. Update the ALB routing rule with a condition that looks for a cookie named version that has a value of beta. Update the test system code to use this cookie to test the beta version of the application.
  2. Create a new ALB, Auto Scaling group, and target group for the beta version of the application. Configure an alternate Amazon Route 53 record for the new ALB endpoint. Use the alternate Route 53 endpoint in the test system requests to test the beta version of the application.
  3. Create a new ALB, Auto Scaling group, and target group for the beta version of the application. Use Amazon CloudFront with Lambda@Edge to determine which specific request will go to the new ALB. Use the CloudFront endpoint to send the test system requests to test the beta version of the application.
  4. Create a new Auto Scaling group and target group for the beta version of the application. Update the ALB routing rule with a condition that looks for a cookie named version that has a value of beta. Use Amazon CloudFront with Lambda@Edge to update the test system requests to add the required cookie when the requests go to the ALB.

Answer(s): A



A team is developing an application that is deployed on Amazon EC2 instances. During testing, the team receives an error. The EC2 instances are unable to access an Amazon S3 bucket.
Which steps should the team take to troubleshoot this issue? (Choose two.)

  1. Check whether the policy that is assigned to the IAM role that is attached to the EC2 instances grants access to Amazon S3.
  2. Check the S3 bucket policy to validate the access permissions for the S3 bucket.
  3. Check whether the policy that is assigned to the IAM user that is attached to the EC2 instances grants access to Amazon S3.
  4. Check the S3 Lifecycle policy to validate the permissions that are assigned to the S3 bucket.
  5. Check the security groups that are assigned to the EC2 instances. Make sure that a rule is not blocking the access to Amazon S3.

Answer(s): A,B

question 35 is incorrect, the correct answer is c, it even states so: explanation: when a vm is infected with ransomware, you should not restore the vm to the infected vm. this is because the ransomware will still be present on the vm, and it will encrypt the files again. you should also not restore the vm to any vm within the companys subscription. this is because the ransomware could spread to other vms in the subscription. the best way to restore a vm that is infected with ransomware is to restore it to a new azure vm. this will ensure that the ransomware is not present on the new vm.
