No - there is only one readable replica in Premium and Business Critical service tiers as per: https://learn.microsoft.com/en-us/azure/azure-sql/database/high-availability-sla-local-zone-redundancy?view=azuresql&tabs=azure-powershell#premium-and-business-critical-service-tier-zone-redundant-availability "As an extra benefit, the local storage availability model includes the ability to redirect read-only Azure SQL connections to one of the secondary replicas."

Selected Answer: A

YES https://docs.microsoft.com/en-us/azure/azure-sql/database/read-scale-out As part of High Availability architecture, each single database, elastic pool database, and managed instance in the Premium and Business Critical service tier is automatically provisioned with a primary read-write replica and several secondary read-only replicas.

Answer I think YES. https://docs.microsoft.com/en-us/azure/azure-sql/database/high-availability-sla As an extra benefit, the premium availability model includes the ability to redirect read-only Azure SQL connections to one of the secondary replicas. This feature is called Read Scale-Out. It provides 100% additional compute capacity at no extra charge to off-load read-only operations, such as analytical workloads, from the primary replica.

Ensure that Sales remains available if a datacenter fails. > true with availability zones because replicas are located in distant regions not the same datacenter
