Quick Answer

The answer is the hybrid cloud deployment model. This is correct because it uniquely satisfies strict data residency regulations by keeping personally identifiable information (PII) on the company’s own physical servers (private cloud) while simultaneously leveraging Azure’s public cloud for compute-intensive analytics that do not process PII. The hybrid model also supports a consistent set of management tools, such as Azure Arc, which provides unified governance, policy enforcement, and monitoring across both on-premises and cloud environments. On the Microsoft Azure Fundamentals AZ-900 exam, this scenario tests your understanding of how hybrid cloud addresses compliance and operational consistency—a common trap is choosing “private cloud” alone, which would fail the need for scalable analytics, or “public cloud,” which violates data residency. Remember the memory tip: “Hybrid for high-stakes data and heavy compute; private alone can’t scale, public alone can’t comply.”

AZ-900 Describe cloud concepts Practice Question

This AZ-900 practice question tests your understanding of describe cloud concepts. 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 is subject to strict data residency regulations that require all personally identifiable information (PII) to remain on their own physical servers. However, they want to use Azure for compute-intensive analytics that do not process PII. They also need a consistent set of management tools to manage resources across both environments. Which cloud deployment model should the company adopt?

Question 1mediummultiple choice

Full question →

A
Public cloud
Why wrong: Incorrect. A public cloud deployment means all resources are hosted by a third-party provider like Microsoft and shared over the internet. This would not allow the company to retain PII on their own physical servers.
B
Private cloud
Why wrong: Incorrect. A private cloud is dedicated to a single organization and is typically hosted on-premises or by a third party exclusively for that organization. While it addresses data residency, it does not provide access to Azure's public cloud services for the analytics workload.
C
Hybrid cloud
Correct. Hybrid cloud integrates on-premises infrastructure (private cloud) with public cloud services like Azure. This allows the company to keep PII on-premises while running analytics in Azure, with consistent management across environments.
D
Community cloud
Why wrong: Incorrect. A community cloud is shared among several organizations with common interests or regulatory requirements. It does not inherently support a mix of on-premises and public cloud resources, and it is not a standard model covered in Azure fundamentals.

Correct answer & explanation

✓

Hybrid cloud

The hybrid cloud model is correct because it allows the company to keep PII on-premises (private cloud) to satisfy data residency regulations while running compute-intensive analytics in Azure (public cloud). Azure Arc provides a consistent set of management tools to govern resources across both environments, enabling unified policy, compliance, and monitoring.

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 'private cloud' as the only option for data residency, overlooking that hybrid cloud allows sensitive data to stay on-premises while leveraging public cloud services for non-sensitive workloads, which is exactly what the scenario describes.

Detailed technical explanation

How to think about this question

Under the hood, hybrid cloud leverages technologies like Azure Arc to extend Azure Resource Manager (ARM) control plane to on-premises servers, enabling consistent role-based access control (RBAC), Azure Policy, and Azure Monitor across environments. In a real-world scenario, the company could deploy Azure Stack HCI on-premises to run VMs locally while bursting compute-intensive workloads to Azure, ensuring PII never leaves the physical boundary. The key subtlety is that hybrid cloud does not require a direct network connection; it can use Azure Arc with disconnected or intermittently connected environments.

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.
