A multinational corporation must ensure that every new Azure subscription automatically conforms to corporate security and compliance baselines. The team wants to deploy a predefined set of Azure resources (e.g., a central logging storage account, a network security group configuration) and apply a standard set of Azure Policy definitions (e.g., restricting allowed VM sizes, enforcing encryption) to any new subscription. They want to manage these as a single, versioned package that can be updated and re-assigned to existing subscriptions. Which Azure service should they 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.
Distractor review
Azure Policy
Azure Policy can enforce rules and compliance on resources, but it cannot deploy Azure resources such as storage accounts or network security groups. It is primarily for auditing and governing existing and new resources, not for deploying infrastructure.
Best answer
Azure Blueprints
Azure Blueprints is designed to define a repeatable set of Azure resources and policies that can be deployed together as a single, versioned artifact. It orchestrates the deployment of ARM templates, policy assignments, role assignments, and other artifacts to ensure new subscriptions meet corporate baselines.
Distractor review
Azure Management Groups
Azure Management Groups provide a hierarchical structure to organize and manage subscriptions, and they can apply policies at scale. However, they cannot deploy resources or define a complete package of resources and policies that can be versioned and updated. They are a management container, not a deployment service.
Distractor review
Azure Resource Manager templates
Azure Resource Manager (ARM) templates are declarative JSON files that define the infrastructure and configuration for Azure resources. While they can deploy resources, they cannot natively include policy assignments or be easily versioned as a governance package that updates existing subscriptions. Azure Blueprints builds on ARM templates by adding versioning and orchestration of multiple artifacts.
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
A company deploys a multi-tier application using Azure virtual machines. 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
A company deploys a line-of-business application on an Azure virtual machine. The IT team wants to ensure the application remains secure. According to the shared responsibility model, which of the following security tasks is the sole responsibility of the customer (the company)?
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 Blueprints — Azure Blueprints is the service that enables the orchestrated deployment of resource templates (such as ARM templates) and policy assignments as a single, versioned package. It allows organizations to define a repeatable set of Azure resources and policies that can be applied to new or existing subscriptions to ensure consistency and compliance. Azure Policy alone can enforce rules but cannot deploy resources. Azure Management Groups only organize subscriptions for hierarchical management. Azure Resource Manager templates can deploy resources but cannot natively enforce policies or be versioned as a governance package in the same way as Blueprints.
