Full question →mediummultiple choiceObjective-mapped
A company operates a hybrid IT environment with virtual machines running on-premises and in Amazon Web Services (AWS). The company also has a growing number of resources in Microsoft Azure. To simplify management, the company wants to use a single Azure service to apply Azure Policy definitions and enable unified inventory and tagging across all virtual machines, regardless of their location. Which Azure service should the company use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Azure Resource Manager
Azure Resource Manager is the deployment and management service for Azure-native resources only. It cannot manage virtual machines hosted on-premises or in other cloud providers.
B
Best answer
Azure Arc
Azure Arc allows you to manage servers and Kubernetes clusters outside of Azure as if they were Azure resources. You can apply Azure Policy, Azure Monitor, and RBAC to these resources, providing unified governance and inventory across on-premises and multiple clouds.
C
Distractor review
Azure Blueprints
Azure Blueprints is used to deploy and orchestrate templated environments within Azure subscriptions. It does not extend management to resources running outside of Azure.
D
Distractor review
Azure Management Groups
Azure Management Groups provide a hierarchical structure for organizing Azure subscriptions and applying governance at scale, but they operate entirely within the Azure tenant and cannot manage resources on other platforms.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A developer is building a serverless application that requires integration with an on-premises SQL Server database for real-time data processing. The on-premises network is connected to Azure via a site-to-site VPN. Which Azure service would allow the function to securely access the on-premises database without exposing it to the public internet?
Question 2
A solutions architect is designing a storage solution for a large media company. The company needs to store video files that are accessed infrequently but must be retained for several years for compliance. Which two Azure storage options meet these requirements? (Select two.)
Question 3

The web tier VMs must be evenly distributed across two distinct data centers within an Azure region to avoid a single point of failure from an infrastructure outage. Which Azure construct should they use to meet this requirement?
Question 4
A company wants to enforce a set of security policies across all their Azure subscriptions. They have created several individual policy definitions. Which Azure construct should they use to group these policies together and assign them as a single package?
Question 5

Question 6
A company develops a web API that runs on Azure App Service. The development team wants to deploy a new version of the API to a staging environment, run integration tests against it, and then gradually shift production traffic to the new version. If any issues are detected, they want to immediately roll back to the previous version without redeploying. Which Azure App Service feature should the team use to meet these requirements?
FAQ
Questions learners often ask
What does this AZ-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure Arc — Azure Arc is the service that extends Azure management capabilities to any infrastructure, including on-premises, multi-cloud (like AWS), and edge environments. With Azure Arc, you can apply Azure Policy, Role-Based Access Control (RBAC), and Azure Monitor to resources outside of Azure, treating them as Azure resources. This enables a consistent management experience across hybrid and multi-cloud estates. The other options are Azure-native services that do not provide this cross-environment capability.
