AZ-900 Describe Azure management and governance Practice Question
A company operates a fleet of on-premises servers running legacy applications. Due to strict regulatory compliance requirements, these servers cannot be migrated to Azure. However, the IT team wants to centrally manage these servers using Azure tools, including applying Azure Policy to enforce configuration standards and using Azure Monitor for log collection and performance monitoring. The team needs to treat these on-premises servers as Azure resources without moving them. Which Azure service should the company use?
⚠ Common exam trap
Many candidates confuse Azure Arc (hybrid management) with Azure Stack Edge (edge compute appliance) or Azure Site Recovery (disaster recovery), as candidates often assume any on-premises integration requires migration or replication rather than extension of the Azure control plane.
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
✓
Azure Arc
Azure Arc is the correct service because it extends Azure Resource Manager (ARM) and Azure management plane to on-premises servers, allowing them to be treated as Azure resources without migration. With Azure Arc, you can apply Azure Policy to enforce configuration standards and use Azure Monitor for log collection and performance monitoring on these servers, meeting the regulatory compliance requirement of keeping them on-premises.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Arc
Why this is correct
Azure Arc enables you to project non-Azure (on-premises, multi-cloud) resources into Azure Resource Manager, allowing you to manage them with Azure tools like Azure Policy and Azure Monitor. This directly meets the requirement to manage on-premises servers without migration.
- ✗
Azure Stack Edge
Why it's wrong here
Azure Stack Edge is a purpose-built hardware appliance for edge computing, data preprocessing, and running Azure services locally. It is not used to manage existing on-premises servers from Azure; rather, it deploys Azure services on-premises.
When this WOULD be correct
A company needs to run Azure services locally on a ruggedized appliance at a remote location with intermittent connectivity, and must process data at the edge before sending it to Azure for further analysis.
- ✗
Azure Site Recovery
Why it's wrong here
Azure Site Recovery is a disaster recovery service that replicates workloads to Azure for failover. It does not provide ongoing management, policy enforcement, or monitoring for the source servers; its primary role is business continuity.
When this WOULD be correct
A company wants to replicate on-premises virtual machines to Azure for disaster recovery, ensuring failover to Azure in case of an on-premises outage, while maintaining the ability to fail back.
- ✗
Azure Policy
Why it's wrong here
Azure Policy is a governance service that enforces rules on Azure resources. However, by itself it cannot apply to on-premises servers unless those servers are first integrated with Azure, which requires Azure Arc to make them appear as Azure resources.
When this WOULD be correct
A company wants to enforce compliance and governance rules across all Azure subscriptions and resources, including preventing deployment of certain resource types or requiring tags. Azure Policy would be the correct service to define and enforce these rules.
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.
✓Azure ArcCorrect answer▾
Why this is correct
Azure Arc enables you to project non-Azure (on-premises, multi-cloud) resources into Azure Resource Manager, allowing you to manage them with Azure tools like Azure Policy and Azure Monitor. This directly meets the requirement to manage on-premises servers without migration.
✗Azure Stack EdgeWrong answer — click to see why▾
Why this is wrong here
Azure Stack Edge is a hardware appliance for edge computing and data transfer to Azure, not for centrally managing on-premises servers as Azure resources. It does not provide Azure Policy or Azure Monitor integration for existing on-premises servers.
★ When this WOULD be the correct answer
A company needs to run Azure services locally on a ruggedized appliance at a remote location with intermittent connectivity, and must process data at the edge before sending it to Azure for further analysis.
Why candidates choose this
Candidates may confuse Azure Stack Edge with Azure Arc because both involve extending Azure capabilities on-premises, but Azure Stack Edge is a physical device for edge compute/storage, not a management plane for existing servers.
✗Azure Site RecoveryWrong answer — click to see why▾
Why this is wrong here
Azure Site Recovery is a disaster recovery service that replicates workloads from on-premises to Azure or between Azure regions, but it does not provide centralized management, Azure Policy enforcement, or Azure Monitor integration for on-premises servers without migrating them.
★ When this WOULD be the correct answer
A company wants to replicate on-premises virtual machines to Azure for disaster recovery, ensuring failover to Azure in case of an on-premises outage, while maintaining the ability to fail back.
Why candidates choose this
Candidates may confuse Site Recovery's replication capabilities with the management and governance features of Azure Arc, assuming that replicating servers to Azure allows them to be managed as Azure resources.
✗Azure PolicyWrong answer — click to see why▾
Why this is wrong here
Azure Policy is a service for creating, assigning, and managing policies, but it cannot manage on-premises servers directly. Without Azure Arc, Azure Policy cannot be applied to non-Azure resources.
★ When this WOULD be the correct answer
A company wants to enforce compliance and governance rules across all Azure subscriptions and resources, including preventing deployment of certain resource types or requiring tags. Azure Policy would be the correct service to define and enforce these rules.
Why candidates choose this
Candidates see 'Azure Policy' in the question and assume it can be used to enforce configuration standards on on-premises servers, not realizing that Azure Policy requires resources to be managed by Azure Arc first.
