A company is hosting a web application in an AWS Region. For disaster recovery purposes, a second region is being used as a standby. Disaster recovery requirements state that session data must be replicated between regions in near-real time and 1% of requests should route to the secondary region to continuously verify system functionality. Additionally, if there is a disruption in service in the main region, traffic should be automatically routed to the secondary region, and the secondary region must be able to scale up to handle all traffic. How should a DevOps engineer meet these requirements?

A Keywords: web application - ElasticBeanstalk, weighted routing required. DynamoDB Global Table required. As understand, Cloudfront not support weighted routing.
Chose A1
A - correct - Elasticbeanstalk - option of ALB to register route53 with active-active alias with health checks and weighted routing "In active-active failover, all the records that have the same name, the same type (such as A or AAAA), and the same routing policy (such as weighted or latency) are active unless Route 53 considers them unhealthy. Route 53 can respond to a DNS query using any healthy record." D - incorrect because no ALB in front of ASG.
