AZ-900 Describe Azure management and governance Practice Question
A company uses Azure to host multiple virtual machines and virtual networks. The network team is responsible for configuring and maintaining virtual networks, subnets, and network security groups. The company wants to ensure that the network team can manage these network resources but cannot modify or delete virtual machines. Which Azure built-in role should the company assign to the network team?
⚠ Common exam trap
Many exam-takers confuse the Contributor role (which grants broad resource management) with the more specific Network Contributor role, or mistakenly think Virtual Machine Contributor includes network management, when in fact it only covers compute resources.
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
✓
Network Contributor
The Network Contributor role grants full management permissions for network resources, including virtual networks, subnets, and network security groups, but does not allow modification or deletion of virtual machines. This aligns exactly with the requirement to restrict the network team to network resources only.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Owner
Why it's wrong here
The Owner role grants full access to all resources in the subscription, including the ability to manage and delete virtual machines. This provides more permissions than necessary for the network team and violates the principle of least privilege.
When this WOULD be correct
A company needs to assign a role that allows a user or group to manage all resources, including creating new resources and assigning roles to others, with no restrictions. For example, a project lead who needs full control over an entire subscription or resource group.
- ✗
Contributor
Why it's wrong here
Although the Contributor role enables a user to create and manage all resources in an Azure subscription—including virtual machines, storage accounts, and web apps—it is far too broad for a network team. Contributor cannot assign permissions to other users (that requires Owner or User Access Administrator), but it can delete, modify, or reconfigure any resource, including non-network resources such as VMs and databases. This violates the principle of least privilege because the network team only needs to manage virtual networks, subnets, network security groups, and load balancers, which are precisely the capabilities isolated in the Network Contributor role.
When this WOULD be correct
If the question asked for a role that allows full management of all resources except access control (RBAC), and there was no restriction on modifying VMs, then Contributor would be correct.
- ✗
Virtual Machine Contributor
Why it's wrong here
The Virtual Machine Contributor role allows managing virtual machines, including starting, stopping, and modifying them. It does not grant permissions to manage virtual networks, subnets, or network security groups, so it would not allow the network team to perform their required duties.
When this WOULD be correct
A company needs a team to manage virtual machines (e.g., deploy, start, stop) but not modify networking resources or other services. Assigning Virtual Machine Contributor grants the necessary VM permissions while restricting changes to networks.
- ✓
Network Contributor
Why this is correct
The Network Contributor role provides full management of network resources such as virtual networks, subnets, network security groups, and load balancers. It does not grant permissions to manage virtual machines or other compute resources, which matches the requirement to restrict the network team's scope.
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-900 exam frequently reuses these exact scenarios with slightly different constraints.
✓Network ContributorCorrect answer▾
Why this is correct
The Network Contributor role provides full management of network resources such as virtual networks, subnets, network security groups, and load balancers. It does not grant permissions to manage virtual machines or other compute resources, which matches the requirement to restrict the network team's scope.
✗OwnerWrong answer — click to see why▾
Why this is wrong here
The Owner role grants full access to all resources, including the ability to modify or delete virtual machines, which violates the requirement to restrict the network team from modifying or deleting VMs.
★ When this WOULD be the correct answer
A company needs to assign a role that allows a user or group to manage all resources, including creating new resources and assigning roles to others, with no restrictions. For example, a project lead who needs full control over an entire subscription or resource group.
Why candidates choose this
Candidates may think Owner is appropriate because it provides broad management capabilities, overlooking the specific requirement to prevent VM modifications or deletions.
✗ContributorWrong answer — click to see why▾
Why this is wrong here
The Contributor role allows full management of all resources in a resource group, including virtual machines, which violates the requirement that the network team cannot modify or delete VMs.
★ When this WOULD be the correct answer
If the question asked for a role that allows full management of all resources except access control (RBAC), and there was no restriction on modifying VMs, then Contributor would be correct.
Why candidates choose this
Candidates may think Contributor is sufficient because it allows management of network resources, but they overlook that it also grants permissions to modify VMs, which is not allowed in this scenario.
✗Virtual Machine ContributorWrong answer — click to see why▾
Why this is wrong here
Virtual Machine Contributor allows management of virtual machines but not virtual networks, subnets, or network security groups, so the network team would lack permissions to configure those resources.
★ When this WOULD be the correct answer
A company needs a team to manage virtual machines (e.g., deploy, start, stop) but not modify networking resources or other services. Assigning Virtual Machine Contributor grants the necessary VM permissions while restricting changes to networks.
Why candidates choose this
Candidates may think 'Virtual Machine Contributor' is broad enough to include networking, or they confuse it with 'Network Contributor' due to similar naming patterns.
