  B. Provision an ALB, an Auto Scaling group, and EC2 instances in a different AWS Region. Update the CloudFront distribution, and create a second origin for the new ALCreate an origin group for the two origins. Configure one origin as primary and one origin as secondary.

• Chose A1

  This architecture is an active-active DR strategy. You would do it with R53 failover because R53 has healthchecks, and once the primary is down all requests go to the failover. With CloudFront failover, all requests would continue to hit the failed primary before being routed to the failover distribution, which increases latency and possibly compounds problems in the failed stack. Interestigly, the best solution would actually be a combination between A and B, as this blog post shows: https://aws.amazon.com/blogs/networking-and-content-delivery/improve-web-application-availability-with-cloudfront-and-route53-hybrid-origin-failover/

• Chose B2

  A is wrong because CloudFront distros can't be added to Route 53. B is correct C is wrong because ALBs are single region and don't do failover. D would work, but is overengineered in this context.
