Final answer:
Management Groups help manage access, policy, and compliance for multiple subscriptions by allowing policies and access controls to be applied across various subscriptions consistently.
Step-by-step explanation:
Containers that help manage access, policy, and compliance for multiple subscriptions are known as Management Groups. These are useful for efficiently managing governance across subscriptions. With Management Groups, an organization can apply policies, and access control is consistently across a number of subscriptions. Resource Groups are a collection of resources that share the same lifecycle, permissions, and policies, but they are scoped to handle objects within a single subscription rather than across multiple subscriptions.
