Selected Answer: AF
A. Placing the application instances in different availability zones: This ensures redundancy and fault tolerance within the same region, so if one availability zone experiences an issue, the application can still run smoothly in another. F. Setting up application instances in multiple regions: This provides redundancy and disaster recovery capabilities across different geographic locations. If one region experiences a major outage, the application can failover to another region, ensuring continuous availability.

A/F- both address availability. So does autoscaling but this was not a resource issue.

Could be true since we are talking about Power Outage in the same Data Center and not caching or scalability performance issue.
