Management Groups for Business Unit Subscriptions

This AZ-104 practice question tests your understanding of manage azure identities and governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company has three business units. Each business unit needs its own subscription for billing and admin delegation. Corporate security wants one policy assignment to cover all current and future subscriptions in each business unit. What structure should you implement?

A
Place all resources in one subscription and separate them only by resource group
Why wrong: This simplifies management but does not meet the requirement for separate billing and admin boundaries.
B
Create a management group for each business unit and place that unit's subscriptions underneath it
Management groups provide a level above subscriptions, making them ideal for consistent policy assignment across multiple subscriptions in a business unit.
C
Assign the policy at each resource group because policies cannot target subscriptions
Why wrong: Azure Policy can be assigned at management group, subscription, resource group, or resource scope.
D
Create one resource group per business unit inside a shared subscription
Why wrong: Resource groups do not provide separate subscription billing or a strong enough boundary for the requirement.

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

✓

Create a management group for each business unit and place that unit's subscriptions underneath it

Management groups allow you to aggregate multiple subscriptions under a single hierarchy, enabling policy assignment at the management group level that applies to all current and future subscriptions within that group. This meets the requirement for per-business-unit billing isolation (via separate subscriptions) and centralized policy enforcement across all subscriptions in each unit.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Place all resources in one subscription and separate them only by resource group
Why it's wrong here
This simplifies management but does not meet the requirement for separate billing and admin boundaries.
When this WOULD be correct
This would be correct if the question required centralized management with no billing separation, and the policy needed to apply to all resources within a single subscription regardless of business unit.
✓
Create a management group for each business unit and place that unit's subscriptions underneath it
Why this is correct
Management groups provide a level above subscriptions, making them ideal for consistent policy assignment across multiple subscriptions in a business unit.

Why it's wrong here
Resource groups do not provide separate subscription billing or a strong enough boundary for the requirement.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.

✓Create a management group for each business unit and place that unit's subscriptions underneath itCorrect answer▾

Why this is correct

Management groups provide a level above subscriptions, making them ideal for consistent policy assignment across multiple subscriptions in a business unit.

✗Place all resources in one subscription and separate them only by resource groupWrong answer — click to see why▾

Why this is wrong here

This option does not meet the requirement for separate subscriptions per business unit, as it uses a single subscription. It also fails to provide a single policy assignment covering all current and future subscriptions because there is only one subscription.

★ When this WOULD be the correct answer

This would be correct if the question required centralized management with no billing separation, and the policy needed to apply to all resources within a single subscription regardless of business unit.

Why candidates choose this

Candidates may think resource groups are sufficient for separation and policy assignment, overlooking the need for distinct subscriptions for billing and admin delegation.

✗Create one resource group per business unit inside a shared subscriptionWrong answer — click to see why▾

Why this is wrong here

This option fails because it does not provide separate subscriptions per business unit for billing and admin delegation, and a single subscription cannot have separate policy assignments for each business unit's resources.

★ When this WOULD be the correct answer

This would be correct if the question required all business units to share a single subscription and the policy needed to be applied to all resources within that subscription, with resource groups used only for organizational purposes.

Why candidates choose this

Candidates may think resource groups can serve as a substitute for subscriptions for policy assignment and delegation, not realizing that policy assignments at the resource group level do not cover future resources in other resource groups or subscriptions.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may think resource groups are sufficient for isolation and policy enforcement, overlooking that management groups provide subscription-level aggregation and inheritance that resource groups cannot achieve across multiple subscriptions.

Detailed technical explanation

How to think about this question

Management groups form a hierarchical structure up to six levels deep, with Azure Policy inheritance flowing from the root management group down through all child management groups and subscriptions. When a policy is assigned at a management group, it applies to all subscriptions under that group, including subscriptions created later, ensuring consistent governance without manual reconfiguration. This is critical for enterprises with dynamic subscription growth or acquisitions.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

TExam Day Tips

Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Same concept, more angles

1 more ways this is tested on AZ-104

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. Based on the exhibit, where should the new subscription be placed so it inherits the production governance baseline automatically?

easy

✓ A.Place the subscription under Prod-MG.
B.Place the subscription under Sandbox-MG.
C.Create a resource group named Finance-Prod instead of assigning a management group.
D.Move the subscription to the tenant root and assign policies later.

Why A: Option A is correct because placing the new subscription under the Prod-MG management group ensures it automatically inherits the Azure Policy and RBAC assignments applied at that level. Management groups in Azure allow hierarchical governance, and any subscription within a management group inherits policies and role assignments from that group and all parent groups. This enables consistent enforcement of the production governance baseline without manual configuration.
