- A
Public cloud
Why wrong: Incorrect. A public cloud would host all resources in Azure, which would place sensitive customer data on Microsoft's infrastructure, likely violating regulatory mandates. The institution specifically needs on-premises control for that data.
- B
Private cloud
Why wrong: Incorrect. A private cloud is dedicated to a single organization, but if it remains entirely on-premises, the institution cannot use Azure's scalable analytics services without building a separate on-premises cloud, which defeats the purpose of leveraging Azure's PaaS/IaaS.
- C
Hybrid cloud
Correct. A hybrid cloud combines on-premises infrastructure with a public cloud like Azure. The institution keeps sensitive financial data on-premises (private cloud) and runs analytics on anonymized data in Azure (public cloud), meeting both regulatory compliance and scalability needs.
- D
Community cloud
Why wrong: Incorrect. A community cloud is shared by several organizations with common concerns (e.g., compliance, security). While it could be used, it does not inherently address the need to keep data on-premises while using Azure separately. The hybrid model is the standard approach for such scenarios.
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 financial institution must keep sensitive customer financial data on-premises to comply with regulatory requirements. However, they also want to use Azure to run compute-intensive analytics on anonymized datasets, taking advantage of scalable resources without managing physical servers. Which cloud deployment model should they adopt?
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
Hybrid cloud
The hybrid cloud model is correct because it allows the financial institution to keep sensitive customer data on-premises for regulatory compliance while leveraging Azure's public cloud for compute-intensive analytics on anonymized datasets. This approach combines the security and control of a private cloud (on-premises) with the scalability and managed services of a public cloud, without requiring the organization to manage physical servers for the analytics workload.
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 may choose public cloud (A) thinking it is the only way to avoid managing physical servers, or private cloud (B) thinking it is required for compliance, without recognizing that hybrid cloud uniquely satisfies both requirements by separating sensitive data (on-premises) from compute-intensive analytics (public cloud).

Detailed technical explanation
How to think about this question
In a hybrid cloud, technologies like Azure ExpressRoute or VPN gateways establish private, low-latency connections between on-premises networks and Azure, enabling secure data transfer for analytics. The anonymized datasets can be processed using Azure services like Azure Synapse Analytics or Azure Databricks, which scale automatically without provisioning physical servers, while the on-premises environment retains full control over sensitive data. This model aligns with regulatory frameworks such as GDPR or PCI DSS, which often mandate data residency or restricted access for specific data categories.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- 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.
