Topic 1 Question 57
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?
In both regions, deploy the application on AWS Elastic Beanstalk and use Amazon DynamoDB global tables for session data. Use an Amazon Route 53 weighted routing policy with health checks to distribute the traffic across the regions.
In both regions, launch the application in Auto Scaling groups and use DynamoDB for session data. Use a Route 53 failover routing policy with health checks to distribute the traffic across the regions.
In both regions, deploy the application in AWS Lambda, exposed by Amazon API Gateway, and use Amazon RDS for PostgreSQL with cross-region replication for session data. Deploy the web application with client-side logic to call the API Gateway directly.
In both regions, launch the application in Auto Scaling groups and use DynamoDB global tables for session data. Enable an Amazon CloudFront weighted distribution across regions. Point the Amazon Route 53 DNS record at the CloudFront distribution.

👍 1alce20202023/04/15 How about D you guys? Option D provides a comprehensive solution that covers all the specified requirements:
Launching the application in Auto Scaling groups ensures scalability and resilience in both regions.
Using DynamoDB global tables allows for near-real-time replication of session data between the regions, ensuring data consistency.
Enabling an Amazon CloudFront weighted distribution across regions allows for the routing of a percentage of requests to the secondary region for continuous verification of system functionality.
Pointing the Amazon Route 53 DNS record at the CloudFront distribution enables automatic traffic routing between the regions based on the weighted distribution configuration
