A company has a multi-tier application that runs six front-end web servers in an Amazon EC2 Auto Scaling group in a single Availability Zone behind an Application Load Balancer (ALB) A solutions architect needs to modify the infrastructure to be highly available without modifying the application Which architecture should the solutions architect choose that provides high availability?

• A.Create an Auto Scaling group that uses three instances across each of two Regions
• B.Modify the Auto Scaling group to use three instances across each of two Availability Zones
• C.Create an Auto Scaling template that can be used to quickly create more instances in another Region
• D.Change the ALB in front of the Amazon EC2 instances in a round-robin configuration to balance traffic to the web tier

A company's database is hosted on an Amazon Aurora MySQL DB cluster in the us-east-1 Region The database is 4 TB in size. The company needs to expand its disaster recovery strategy to the us-west-2 Region The company must have the ability to fail over to us-west-2 with a recovery time objective (RTO) of 15 minutes.
What should a solutions architect recommend to meet these requirements?

• A.Create an AWS CloudFormation script to create another Aurora MySQL DB cluster in us-west-2 in case of failure Configure an Amazon EventBridge (Amazon CloudWatch Events) rule that invokes an AWS Lambda function upon receipt of resource events. Configure the Lambda function to deploy the AWS CloudFormation stack in us-west-2 when failure is detected.
• B.Take a snapshot of the DB cluster in us-east-1. Configure an Amazon EventBridge (Amazon CloudWatch Events) rule that invokes an AWS Lambda function upon receipt of resource events Configure the Lambda function to copy the snapshot to us-west-2 and restore the snapshot in us-west-2 when failure is detected.
• C.Create a Multi-Region Aurora MySQL DB cluster in us-east-1 and us-west-2 Use an Amazon Route 53 health check to monitor us-east-1 and fail over to us-west-2 upon failure
• D.Recreate the database as an Aurora global database with the primary DB cluster in us-east-1 and a secondary DB cluster in us-west-2 Configure an Amazon EventBridge (Amazon CloudWatch Events) rule that invokes an AWS Lambda function upon receipt of resource events Configure the Lambda function to promote the DB cluster in us-west-2 when failure is detected.

A solutions architect is creating a new VPC design. There are two public subnet for the load balancer, two private subnets for web servers, and two private subnets for MySQL. The web serves use only HTTPS. The solutions architect has already created a security group for the load Balancer allowing port 443 from 0.0 0.0/0.
Company policy requires that each resource has the least access required to still be able to perform its tasks.
Which additional configuration strategy should the solution architect use to meet these requirements?

• A.Create a network ACL for the web servers and allow port 443 from 0.0.0.0/0. Create a network ACL for the MySQL servers and allow port 3306 from the web servers security group
• B.Create a network ACL for the web servers and allow port 443 from the web balancer. Create a network ACL for the MySQL servers and allow port 3306 from the web servers security group.
• C.Create a security group far the web servers and allow port 443 from 0.0.0.070. Create a security group tor the MySQL serve's aid allow port 3306 from the web servers security group.
• D.Create a security group for the web servers and allow port 443 from the load balancer. Create a security group tor the MySQL servers and allow port 3306 from the web sewers security group

A web application runs on Amazon EC2 instances behind an Application Load Balancer The application allows users to create custom reports of historical weather data. Generating a report can take up to 5 minutes.
These long-running requests use many of the available incoming connections, making the system unresponsive to other users How can a solutions architect make the system more responsive?

• A.Publish the reports to Amazon S3 and use Amazon CloudFront for downloading lo the user.
• B.Increase the Idle timeout on the Application Load Balancer to 5 minutes.
• C.Use Amazon SOS with AWS Lambda to generate reports
• D.Update the client-side application code to increase its request timeout to 5 minutes.

A company is building its web application using containers on AWS. The company requires three instances of the web application to run at all times. The application must be able to scale to meet increases in demand.
Management is extremely sensitive to cost but agrees that the application should be highly available.
What should a solutions architect recommend?

• A.Create an Amazon Elastic Container Service (Amazon ECS) cluster using the Fargate launch type with one container instance in three different Availability Zones. Create a task definition for the web application.
  Create an ECS service with a desired count of three tasks.
• B.Create an Amazon Elastic Container Service (Amazon ECS) cluster using the Amazon EC2 launch type with one container instance in two different Availability Zones. Create a task definition for the web application. Place two tasks on one container instance and one task on the remaining container instance.
• C.Create an Amazon Elastic Container Service (Amazon ECS) cluster using the Fargate launch type. Create a task definition for the web application. Create an ECS service with a desired count of three tasks.
• D.Create an Amazon Elastic Container Service (Amazon ECS) cluster using the Amazon EC2 launch type with three container instances in one Availability Zone. Create a task definition for the web application.
  Place one task for each container instance.
