Azure Architecture and Services
The largest skill area (35–40%): Azure’s physical and management hierarchy, plus core compute, networking, and storage services.
Azure’s physical infrastructure is organized as regions (geographic sets of datacenters), availability zones (physically separate datacenters within a region for resilience), and region pairs (for geo-redundancy).
The management hierarchy organizes resources top-down: management groups → subscriptions → resource groups → resources. A resource group is a logical container for resources that share a lifecycle. Azure Resource Manager (ARM) is the deployment and management layer that handles every request, enabling templates, tagging, and role-based access.
What provides physically separate datacenters within a single Azure region for resilience?
Which is the correct order of the Azure management hierarchy, broadest first?
