  Explanation/Reference:

  The benefits of Amazon EC2 Auto Scaling are:

  A. Improved health and availability of applications

  C. Optimized performance and costs

  Therefore, the correct options are A and C. EC2 Auto Scaling helps in automatically adjusting the capacity of EC2 instances in response to changes in demand. This ensures that the application is always available and can handle varying levels of traffic. It also helps in optimizing the performance and costs by automatically scaling up and down the instances as per the demand, thus avoiding over-provisioning or under-provisioning of resources. However, EC2 Auto Scaling does not provide automated snapshots of data or cross-region replication.
