A company is running a web application in the AWS Cloud. The application consists of dynamic content that is created on a set of Amazon EC2 instances. The EC2 instances run in an Auto Scaling group that is configured as a target group for an Application Load Balancer (ALB).
The company is using an Amazon CloudFront distribution to distribute the application globally. The CloudFront distribution uses the ALB as an origin. The company uses Amazon Route 53 for DNS and has created an A record of www.example.com for the CloudFront distribution.
A solutions architect must configure the application so that itis highly available and fault tolerant. Which solution meets these requirements?

1. A. Provision a full, secondary application deployment in a different AWS Regio
2. B. Update the Route 53 A record to be a failover recor
3. C. Add both of the CloudFront distributions as value
4. D. Create Route 53 health checks.
5. E. Provision an ALB, an Auto Scaling group, and EC2 instances in a different AWS Regio
6. F. Update the CloudFront distribution, and create a second origin for the new AL
7. G. Create an origin group for the two origin
8. H. Configure one origin as primary and one origin as secondary.
9. I. Provision an Auto Scaling group and EC2 instances in a different AWS Regio
10. J. Create a second target for the new Auto Scaling group in the AL
11. K. Set up the failover routing algorithm on the ALB.
12. L. Provision a full, secondary application deployment in a different AWS Regio
13. M. Create a second CloudFront distribution, and add the new application setup as an origi
14. N. Create an AWS Global Accelerator accelerato
15. O. Add both of the CloudFront distributions as endpoints.

You can set up CloudFront with origin failover for scenarios that require high availability. To get started, you create an origin group with two origins: a primary and a secondary. If the primary origin is unavailable, or returns specific HTTP response status codes that indicate a failure, CloudFront automatically switches to the secondary origin.

3. C. Invoke an AWS Lambda function to perform image processing when a message is available in the queue.
4. D. Invoke an S3 Batch Operations job to perform image processing when a message is available in the queue.
5. E. Send a push notification to the mobile app by using Amazon Simple Notification Service (Amazon SNS) when processing is complete.
