Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies. It supports adding an existing ECS instance into the scaling group but imposes certain requirements on instance region. In this case, which of the following statements is true?
When adding an existing ECS instance to a scaling group, the instance and the scaling group must be in the same region but not necessarily the same zone. This allows for flexibility in distributing instances across different availability zones within the same region for better high availability and fault tolerance.

Yes, you can add existing ECS instances to a scaling group. Make sure that the ECS instances meet the following conditions: The ECS instances and the scaling group must be in the same region. For more information, see Regions and zones. The ECS instances are in the Running state. For more information, see Instance lifecycle. The ECS instances are not added to other scaling groups.
Answer is A

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.
A. The instance and the scaling group must be in the same region but not necessarily the same zone. Scaling group can configure multi-zone
