Sample Questions

Question #288 / 529

A company is developing a global video streaming platform that allows users to upload and transcode videos in real-time. At peak, the service must handle 15,000 concurrent uploads worldwide. After upload, videos must be processed to generate adaptive bitrate streams, which are then distributed via a content delivery network (CDN).

Which architecture should a solutions architect recommend?

A

Store uploaded videos in Amazon Elastic File System (Amazon EFS). Use Amazon CloudWatch Logs to track upload events. Deploy Amazon EC2 instances that monitor CloudWatch Logs to trigger video processing. Store transcoded videos in a separate EFS directory. Configure Amazon CloudFront with an EC2 instance as the origin.

B

Store uploaded videos in an Amazon S3 bucket and configure S3 event notifications to publish to Amazon Simple Notification Service (Amazon SNS). Use EC2 instances behind an Application Load Balancer (ALB) to consume SNS messages for processing. Store transcoded videos in Amazon EFS. Scale EC2 instances using CloudWatch metrics for SNS message volume. Set CloudFront's origin to the ALB.

C

Store uploaded videos in an Amazon S3 bucket and configure S3 event notifications to send messages to an Amazon Simple Queue Service (SQS) queue. Deploy auto-scaling EC2 instances to process videos by pulling messages from the SQS queue. Store transcoded videos in another S3 bucket. Scale EC2 instances based on SQS queue depth using CloudWatch. Configure CloudFront with the processed S3 bucket as the origin.

D

Store uploaded videos on a shared Amazon Elastic Block Store (EBS) volume attached to EC2 Spot instances. Track processing status in an Amazon DynamoDB table. Use Amazon EventBridge rules to scale EC2 instances. Configure CloudFront with an Elastic Load Balancer (ELB) as the origin.

Question #476 / 529

A company hosts its internal applications in an Amazon VPC and uses Active Directory Domain Services (AD DS) deployed on an EC2 instance. The company's security team mandates that all access to VPC-hosted services must occur through a VPN connection, and multi-factor authentication (MFA) must be enforced for VPN access. As a Solutions Architect, what should you recommend to comply with these requirements?

A

Deploy an AWS Site-to-Site VPN connection. Integrate the VPN with AD DS for authentication. Require engineers to use Amazon AppStream 2.0 with MFA enabled to establish the VPN connection.

B

Set up an AWS Client VPN endpoint. Create an AD Connector directory to integrate with the existing AD DS. Enable MFA on the AD Connector and configure the AWS Client VPN to use it for authentication.

C

Implement an AWS VPN CloudHub architecture with multiple Site-to-Site VPN connections. Integrate the VPN CloudHub with AD DS. Use AWS Directory Service with MFA enabled to authenticate VPN users.

D

Provision an Amazon WorkSpaces gateway. Configure integration between WorkSpaces and AD DS. Enable MFA in Amazon WorkSpaces and require users to connect via the WorkSpaces client to access VPC resources.

Question #123 / 557

A company must deploy all its Amazon Aurora DB clusters using AWS CloudFormation templates within an AWS CodePipeline CI/CD workflow. The master password for each DB cluster must be automatically generated during deployment with the LEAST development effort.

Which solution will meet these requirements?

A

Create an AWS Lambda-backed CloudFormation custom resource. Write Lambda code to generate a secure password using AWS KMS. Return the password via the custom resource response. Use Fn::GetAtt to retrieve the password and apply it to the Aurora DB cluster resource.

B

Add an AWS CodeBuild step in CodePipeline to execute a script that generates a random password using OpenSSL. Pass the password as a CloudFormation parameter with NoEcho enabled. Reference the parameter in the Aurora DB cluster resource.

C

Create an AWS Lambda-backed custom resource to generate a secure password. Store the password in AWS Secrets Manager using a SecretsManager::Secret resource. Use a secretsmanager dynamic reference in the Aurora DB cluster resource to retrieve the password.

D

Use the AWS::SecretsManager::Secret resource to generate and store a secure password. Reference the password directly in the Aurora DB cluster resource using the secretsmanager dynamic reference syntax.

Question #120 / 557
