Describe Azure management and governance →mediumMultiple ChoiceObjective-mapped

Quick Answer

Azure Resource Graph is the correct choice because it enables running a single cross-subscription query across more than 50 Azure subscriptions using Kusto Query Language (KQL), allowing the security team to instantly retrieve all virtual machines with public IPs along with their subscription and resource group details without custom scripts or iterative loops. This service works by indexing Azure resources into a normalized table that can be queried at the management group or tenant scope, making it ideal for fast, large-scale auditing scenarios. On the AZ-900 exam, this question tests your understanding of Azure Resource Graph’s role in governance and compliance at scale, often contrasting it with Azure Resource Manager (which operates per-subscription) or Azure Monitor (which focuses on metrics and logs). A common trap is confusing Azure Resource Graph with Azure Resource Manager—remember that Resource Graph is for *querying* resource metadata across boundaries, not for deploying or managing resources. Memory tip: think “Graph = cross-subscription search engine for resources.”

AZ-900 Describe Azure management and governance Practice Question

This AZ-900 practice question tests your understanding of describe azure management and governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company's security team needs to audit all virtual machines (VMs) that have a public IP address directly attached, across more than 50 Azure subscriptions organized under several management groups. The team wants to run a single query to get a list of these VMs along with the subscription and resource group details. The solution must provide fast results without the need to write custom scripts or iterate through each subscription individually. Which Azure service should the team use?

Full question →

A
Azure Resource Graph
Azure Resource Graph allows querying across all Azure subscriptions and management groups using a single query, making it the correct choice for this cross-subscription audit scenario.
B
Azure Policy
Why wrong: Azure Policy is used to enforce rules and effects on resources, not to query existing resource configurations across subscriptions. It can audit compliance but does not provide an ad-hoc query service like Resource Graph.
C
Azure Monitor
Why wrong: Azure Monitor collects and analyzes telemetry data (metrics, logs) from resources, but it is not optimized for querying resource metadata such as public IP assignments across many subscriptions. Resource Graph is the appropriate tool for inventory and discovery queries.
D
Azure Resource Manager
Why wrong: Azure Resource Manager is the deployment and management service for Azure resources. It does not provide a built-in query engine for searching resources across multiple subscriptions efficiently; that is the purpose of Azure Resource Graph.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Azure Resource Graph

Azure Resource Graph (ARG) is the correct choice because it provides a powerful, queryable interface (using Kusto Query Language, KQL) that can search across all Azure subscriptions, management groups, and resource groups in a single query. It can quickly return a list of VMs with public IPs attached, along with their subscription and resource group metadata, without requiring custom scripts or iterative loops. This directly meets the requirement for fast, cross-subscription auditing with minimal overhead.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse Azure Policy's compliance evaluation capabilities with the ability to perform ad-hoc, cross-subscription queries, not realizing that Policy is for rule enforcement and reporting on non-compliant resources, not for flexible, query-based resource discovery like Azure Resource Graph provides.

Detailed technical explanation

How to think about this question

Under the hood, Azure Resource Graph uses a distributed query engine that indexes resource properties (including network interfaces and public IP associations) across all subscriptions in a tenant, allowing KQL queries like `where type =~ 'microsoft.compute/virtualmachines' and properties.networkProfile.networkInterfaces[0].properties.ipConfigurations[0].properties.publicIPAddress != ''` to return results in seconds. A subtle behavior is that ARG queries are eventually consistent (typically within 5 minutes of a resource change), so for real-time auditing of recently modified VMs, a direct API call might be more accurate, but for most audit scenarios this delay is acceptable. In a real-world scenario, a security team could use ARG to generate a daily report of all VMs with public IPs, then feed that into a ticketing system for remediation, all without writing PowerShell loops.

Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
