Microsoft Azure Fundamentals AZ-900 Practice Question

An Azure subscription is a logical container that groups the resources you deploy and manage in Azure. All usage and charges for those resources are rolled up and invoiced together, making the subscription the fundamental billing boundary. Subscriptions are associated with a single billing account but can be organized under management groups for governance. While subscriptions also impose certain service limits and act as an administrative scope, their core function is to collect usage so that resources are billed together. A management group organizes multiple subscriptions, an Azure account or tenant represents identity, and regions determine where resources run-none of which are the primary purpose of a subscription.
