A. The instance and the scaling group must be in the same region but not necessarily the same zone. When adding an existing ECS (Elastic Compute Service) instance to an Auto Scaling group, the instance and the scaling group must be in the same region, but they do not necessarily have to be in the same availability zone (zone). This flexibility allows you to distribute your instances across different availability zones within the same region for high availability and fault tolerance.
