Which Azure capability lets an organization manage resources across multiple clouds and on-premises environments from a single control plane?
Show answer and explanation
Answer: B
Azure Arc projects servers, VMs hosted in other clouds, and Kubernetes clusters running anywhere into Azure Resource Manager, so they can be governed with Azure Policy, authorized with RBAC, monitored with Azure Monitor, and managed from one portal regardless of where they physically run.
ARM is the control plane only inside Azure, Monitor is the telemetry and analysis layer without its own cross-cloud projection, and DevOps is a delivery tooling suite with no role in governing infrastructure spread across environments.
Why the other options are wrong
- A. Azure Resource Manager manages resources that live in Azure; servers and services on-premises or in other clouds appear only if Azure Arc projects them in.
- C. Azure Monitor ingests telemetry and supports analysis and alerting, but it does not by itself extend Azure's management model to hybrid and multi-cloud infrastructure.
- D. Azure DevOps is a suite of repos, pipelines, and boards for the software delivery process, not a control plane over heterogeneous infrastructure.
