AZ-900 - Describe Azure Management and Governance - Section 3.1

Describe cost management in Azure including factors affecting cost, the pricing and TCO calculators, Microsoft Cost Management, and tags.

Describe the factors that affect Azure costs - resource type, consumption, region, and licensing - and use the Pricing calculator and Total Cost of Ownership (TCO) calculator to estimate and compare expenditure. Apply Microsoft Cost Management and resource tags to monitor spending, allocate costs to teams or projects, and identify optimisation opportunities.

Practice question for this objective

Free sampleDescribe Azure Management and Governancemedium

Your organisation runs servers and Kubernetes clusters in an on-premises datacentre and in a competing public cloud, and wants to govern and monitor them through the same Azure control surface as if they were Azure resources. Which capability is designed to project these non-Azure resources into Azure Resource Manager?

  • AAzure Resource Manager, the management layer that handles requests for resources
  • BAzure Arc, which projects non-Azure resources into Azure Resource Manager Correct
  • CThe Azure portal, the graphical console used to manage your resources
  • DAzure Cloud Shell, the browser-based shell for running commands
Azure Arc extends Azure management and governance to resources outside Azure by projecting them into Azure Resource Manager. Azure Arc is the capability that extends Azure management and governance outward: it works with Azure Resource Manager to project existing non-Azure servers, Kubernetes clusters, and databases into ARM, letting hybrid and multicloud resources be inventoried, governed, and monitored exactly as if they were running in Azure.

Why A is wrong: Azure Resource Manager is the management layer that processes create, update, and delete requests for resources, and Arc relies on it, but ARM by itself does not project external servers or clusters into Azure.

Why B is correct: Correct. Azure Arc is the capability that extends Azure management and governance outward: it works with Azure Resource Manager to project existing non-Azure servers, Kubernetes clusters, and databases into ARM, letting hybrid and multicloud resources be inventoried, governed, and monitored exactly as if they were running in Azure.

Why C is wrong: The Azure portal is a web-based graphical console for building and monitoring resources, but it is a management interface and does not provide the hybrid or multicloud projection that brings outside resources under Azure governance.

Why D is wrong: Azure Cloud Shell is a browser-based shell hosting the Azure CLI and Azure PowerShell, but it only runs commands and cannot project on-premises or other-cloud resources into Azure Resource Manager.
