AZ-900 Describe Azure management and governance Practice Question

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 Policy

  Why it's wrong here

  Azure Policy is a governance service that enforces rules on Azure resources, such as requiring specific SKU sizes, tags, or security settings, and it can deny non-compliant resource creation or apply remediation. However, policy definitions work on resource properties, not on monetary cost accumulations — you cannot write a policy that checks your monthly invoice total or triggers an alert when your bill crosses a dollar amount. While you could use policy to limit expensive resource types, that is a resource governance approach, not a spending-limit control, so it does not satisfy the requirement to be notified when costs approach a limit.

  Azure Cost Management budgets

  Why this is correct

  Azure Cost Management budgets enable you to define a monetary threshold for a subscription, resource group, or management group over a monthly, quarterly, or annual period, and then configure alerts that fire when actual spending reaches a specified percentage of that budget (for example, 90%). These alerts can send email notifications or trigger automated actions, such as a webhook to an automation runbook, making them the correct native service for notifying you when costs approach or exceed your limits. While budgets do not automatically block resource creation by default, they are the primary cost governance tool for setting spending thresholds and alerting, which directly matches the scenario in the question.

• ✗

  Azure Reservations

  Why it's wrong here

  Azure Reservations let you prepay for committed amounts of specific services, like virtual machines or SQL Database, for one or three years in exchange for discounted rates. This is a purchasing and pricing mechanism that lowers the unit cost of resources, but it does not set a spending threshold or monitor actual usage against that threshold. Reservations actually require an upfront financial commitment, and they do not emit alerts when your overall bill grows; therefore, they are a cost-saving tactic, not a spending-limit control.

• ✗

  Azure Advisor cost recommendations

  Why it's wrong here

  Azure Advisor is a personalized cloud efficiency consultant that analyzes your deployed resources and provides recommendations to optimize costs, such as right-sizing underutilized virtual machines or removing idle resources. However, it is purely advisory — it does not track your actual cumulative spending against a threshold you define, nor can it trigger alerts when spending approaches a limit. Advisor helps you reduce costs over time, but it does not provide spending limit control or budget alerts.
