A company has resources across multiple Azure subscriptions and needs a single dashboard to view cost data across all of them. Which Azure service provides this?
Cost Management provides a unified cost view across subscriptions and management groups, with analysis, budgets, and recommendations.
Why this answer
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.
Exam trap
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.
How to eliminate wrong answers
Option A is wrong because Azure Monitor is designed for collecting and analyzing telemetry data (metrics, logs) from Azure resources for performance and health monitoring, not for aggregating cost data across subscriptions. Option C is wrong because Azure Advisor provides personalized recommendations for optimizing Azure resources (e.g., cost, security, reliability) but does not offer a dashboard for viewing cost data across subscriptions. Option D is wrong because Azure Policy enforces organizational standards and compliance rules on resources (e.g., restricting resource types or locations) and does not provide cost aggregation or dashboarding capabilities.
