A financial services company in North America plans to release a new online web application to its customers on AWS . The company will launch the application in the us-east-1 Region on Amazon EC2 instances. The application must be highly available and must dynamically scale to meet user traffic. The company also wants to implement a disaster recovery environment for the application in the us-west-1 Region by using active-passive failover.
Which solution will meet these requirements?

1. A. Create a VPC in us-east-1 and a VPC in us-west-1 Configure VPC peering In the us-east-1 VP
2. B. create an Application Load Balancer (ALB) that extends across multiple Availability Zones in both VPCs Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in both VPCs Place the Auto Scaling group behind the ALB.
3. C. Create a VPC in us-east-1 and a VPC in us-west-1. In the us-east-1 VP
4. D. create an Application Load Balancer (ALB) that extends across multiple Availability Zones in that VP
5. E. Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in the us-east-1 VPC Place the Auto Scaling group behind the ALB Set up the same configuration in the us-west-1 VP
6. F. Create an Amazon Route 53 hosted zone Create separate records for each ALB Enable health checks to ensure high availability between Regions.
7. G. Create a VPC in us-east-1 and a VPC in us-west-1 In the us-east-1 VP
8. H. create an Application LoadBalancer (ALB) that extends across multiple Availability Zones in that VPC Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in the us-east-1 VPC Place the Auto Scaling group behind the ALB Set up the same configuration in the us-west-1 VPC Create an Amazon Route 53 hosted zon
9. I. Create separate records for each ALB Enable health checks and configure a failover routing policy for each record.
10. J. Create a VPC in us-east-1 and a VPC in us-west-1 Configure VPC peering In the us-east-1 VP
11. K. create an Application Load Balancer (ALB) that extends across multiple Availability Zones in Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in both VPCs Place the Auto Scaling group behind the ALB Create an Amazon Route 53 host.. Create a record for the ALB.

A company wants to improve cost awareness for its Amazon EMR platform The company has aWocated budgets for each team's Amazon EMR usage When a budgetary threshold is reached a notification should be sent by email to the budget office's distribution list Teams should be able lo view their EMR cluster expenses to date A solutions architect needs to create a solution that ensures this policy is proactively and centrally enforced in a multi-account environment
Which combination of steps should the solutions architect take to meet these requirements? (Select TWO.)

1. A. Update the AWS CloudFormation template to include the AWS Budgets Budget resource with the NotificationsWithSubscnbers property
2. B. Implement Amazon CloudWatch dashboards for Amazon EMR usage
3. C. Create an EMR bootstrap action that runs at startup that calls the Cost Explorer API to set the budget on the cluster with the GetCostForecast and NotificationsWithSubscnbers actions
4. D. Create an AWS Service Catalog portfolio for each tea
5. E. Add each team's Amazon EMR cluster as an AWS CloudFormation template to their Service Catalog portfolio as a Product
6. F. Create an Amazon CloudWatch metric for billing Create a custom alert when costs exceed the budgetary threshold.

A company has a web application that allows users to upload short videos. The videos are stored on Amazon EBS volumes and analyzed by custom recognition software for categorization.
The website contains stat c content that has variable traffic with peaks in certain months. The architecture consists of Amazon EC2 instances running in an Auto Scaling group for the web application and EC2 instances running in an Auto Scaling group to process an Amazon SQS queue The company wants to
re-architect the application to reduce operational overhead using AWS managed services where possible and remove dependencies on third-party software.
Which solution meets these requirements?

1. A. Use Amazon ECS containers for the web application and Spot Instances for the Auto Scaling group that processes the SQS queu
2. B. Replace the custom software with Amazon Recognition to categorize the videos.
3. C. Store the uploaded videos n Amazon EFS and mount the file system to the EC2 instances for Te web applicatio
4. D. Process the SOS queue with an AWS Lambda function that calls the Amazon Rekognition API to categorize the videos.
5. E. Host the web application in Amazon S3. Store the uploaded videos in Amazon S3. Use S3 event notifications to publish events to the SQS queue Process the SQS queue with an AWS Lambda function that calls the Amazon Rekognition API to categorize the videos.
6. F. Use AWS Elastic Beanstalk to launch EC2 instances in an Auto Scaling group for the web application and launch a worker environment to process the SQS queue Replace the custom software with Amazon Rekognition to categorize the videos.

A company is running a three-tier web application in an on-premises data center. The frontend is served by an Apache web server, the middle tier is a monolithic Java application, and the storage tier is a PostgreSOL database.
During a recent marketing promotion, customers could not place orders through the application because the application crashed An analysis showed that all three tiers were overloaded. The application became unresponsive, and the database reached its capacity limit because of read operations. The company already has several similar promotions scheduled in the near future.
A solutions architect must develop a plan for migration to AWS to resolve these issues. The solution must maximize scalability and must minimize operational effort.
Which combination of steps will meet these requirements? (Select THREE.)

1. A. Refactor the frontend so that static assets can be hosted on Amazon S3. Use Amazon CloudFront to serve the frontend to customer
2. B. Connect the frontend to the Java application.
3. C. Rehost the Apache web server of the frontend on Amazon EC2 instances that are in an Auto Scaling grou
4. D. Use a load balancer in front of the Auto Scaling grou
5. E. Use Amazon Elastic File System (Amazon EFS) to host the static assets that the Apache web server needs.
6. F. Rehost the Java application in an AWS Elastic Beanstalk environment that includes auto scaling.
7. G. Refactor the Java applicatio
8. H. Develop a Docker container to run the Java applicatio
9. I. Use AWS Fargate to host the container.
10. J. Use AWS Database Migration Service (AWS DMS) to replatform the PostgreSQL database to an Amazon Aurora PostgreSQL databas
11. K. Use Aurora Auto Scaling for read replicas.
12. L. Rehost the PostgreSQL database on an Amazon EC2 instance that has twice as much memory as the on-premises server.

A company wants to use AWS to create a business continuity solution in case the company's main on-premises application fails. The application runs on physical servers that also run other applications. The on-premises application that the company is planning to migrate uses a MySQL database as a data store.

10. J. Create a DMS replication task to copy the existing data to the target DB cluste
11. K. Create a local AWS Schema Conversion Tool (AWS SCT) change data capture(CDC) task to keep the data synchronize
12. L. Install the rest of the software on EC2 instances by starting with a compatible base AMI.
