Question

A SysOps administrator manages a web application hosted behind two separate Application Load Balancers in the same Region: the current production stack and a newly deployed stack. The team wants to gradually shift a small percentage of live user traffic to the new stack to validate it before full rollout, and be able to adjust the traffic split at any time without code changes. Which Amazon Route 53 configuration meets this requirement?

Accepted Answer

Create two weighted alias records for the same domain name, each pointing to one ALB, and assign proportional weight values to control the traffic split.

Answer

Create latency-based alias records pointing to each ALB so users are routed to the fastest responding stack.

Answer

Create a failover record set with the production ALB as primary and the new ALB as secondary, using a health check on the primary.

Answer

Create a multivalue answer routing policy with both ALBs so Route 53 returns both endpoints and clients choose randomly.
