The correct answer is Azure Cost Management + Billing because it provides a single dashboard that aggregates cost data across multiple Azure subscriptions, enabling centralized monitoring and analysis of spending. This service directly addresses the need for a unified view by pulling usage and billing information from all subscriptions into one interface, supporting cross-subscription views, budget tracking, and cost allocation. On the AZ-900 exam, this question tests your understanding of how Azure organizes cost governance at scale, often appearing alongside scenarios about consolidating billing or setting spending limits. A common trap is confusing this with Azure Advisor, which offers cost recommendations but not a unified dashboard, or with Azure Monitor, which focuses on performance metrics rather than billing data. Remember the memory tip: “Cost Management + Billing is the one dashboard to rule all subscriptions.”

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Cost Management + Billing
Azure Cost Management + Billing is the correct service because it provides a unified dashboard that aggregates cost data across multiple Azure subscriptions, enabling centralized monitoring and analysis of spending. It supports cross-subscription views, budget tracking, and cost allocation, which directly addresses the requirement for a single dashboard to view cost data across all subscriptions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Azure Advisor

✗
Azure Policy
Why it's wrong here
Azure Policy enforces governance — it doesn't track or display cost data.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Monitor (which shows metrics and logs) with cost monitoring, but Azure Monitor does not aggregate billing data across subscriptions—Cost Management + Billing is the dedicated service for financial governance.
Detailed technical explanation
How to think about this question
Azure Cost Management + Billing leverages the Azure Resource Manager (ARM) API to pull consumption and billing data from each subscription, then normalizes it into a single view using management groups or billing scopes. It supports cost analysis by resource tags, resource groups, or custom date ranges, and can export raw cost data to Azure Storage or Power BI for advanced reporting. A real-world scenario is a global enterprise with 50 subscriptions across departments using Cost Management to set budgets and alerts for each department while viewing consolidated spend in one dashboard.

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.
