AZ-900 Describe Azure management and governance Practice Question
Which Azure feature provides a way to organize and manage access to resources by creating a hierarchy above subscriptions?
⚠ Common exam trap
Many exam-takers confuse resource groups (which organize resources within a subscription) with management groups (which organize subscriptions themselves), leading candidates to incorrectly select resource groups as the hierarchy above subscriptions.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Management Groups
Management Groups provide a hierarchical structure above Azure subscriptions, enabling centralized policy and access management across multiple subscriptions. This allows you to apply Azure Policy and Role-Based Access Control (RBAC) at a higher level, which then cascades down to all child subscriptions and resource groups within the hierarchy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Resource groups
Why it's wrong here
A resource group is a logical container within a single Azure subscription, holding resources like VMs and databases to manage them with shared lifecycles, RBAC, and policies. It cannot sit above subscriptions because every resource group is itself scoped to exactly one subscription. Therefore, resource groups operate below the subscription boundary, not above it.
- ✗
Azure tags
Why it's wrong here
Azure tags are key–value metadata pairs attached to resources or resource groups for facets such as cost tracking, ownership, or environment classification. They are not hierarchy objects and cannot contain or organize subscriptions; tags simply annotate resources without affecting governance inheritance. Thus, tags do not create any layer above subscriptions.
- ✓
Management Groups
Why this is correct
Management groups are the topmost scope in the Azure hierarchy, positioned directly above subscriptions. They enable governance across many subscriptions by inheriting Azure Policy and RBAC assignments down to every subscription and resource within them. Because this inheritance is the defining mechanism, management groups are the correct answer for what sits above subscriptions.
- ✗
Azure tenants
Why it's wrong here
An Azure tenant, specifically an Azure AD tenant, is a dedicated identity directory that authenticates users, groups, and service principals and controls access to subscriptions. It is an identity boundary, not a management hierarchy node: subscriptions are created inside a tenant and trust the tenant for identity, but tenants do not sit 'above' subscriptions structurally. Management groups are the actual higher-level container.
Quick reference
Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
