  D is right The current solution uses health checks and failover routing policy, which can take more than 1 minute to fail over. By creating an origin group with two origins (one for each backend service region), you can ensure that the CloudFront distribution will automatically switch to the other origin when the primary origin becomes unavailable. Setting the TTL to 4 seconds for the existing record sets (option B) would not significantly improve failover time, as it's still a health check-based approach. Deploying an additional CloudFront distribution and creating new Route 53 record sets with health checks (option A) is unnecessary and would add complexity. Creating new record sets using latency routing policy (option C) might help distribute traffic between the two origins, but it wouldn't improve failover time.
