Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A hospital maintains its patient records on physical servers located within its own on-premises data center due to strict data residency regulations that prohibit patient data from leaving the country. For analytical workloads that process only anonymized data, the hospital uses Azure virtual machines and Azure Synapse Analytics. This combination of on-premises and cloud resources best describes which cloud deployment model?
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
Public cloud
Incorrect. A public cloud model would host all workloads in Azure, but here the hospital keeps patient records on-premises, so this is not a pure public cloud deployment.
B
Distractor review
Private cloud
Incorrect. A private cloud is dedicated to a single organization and can be on-premises or hosted. However, in this scenario, the hospital also uses Azure (a public cloud), so the overall model is hybrid, not purely private.
C
Best answer
Hybrid cloud
Correct. The hospital uses both on-premises infrastructure (for sensitive patient data) and public cloud services (Azure for analytics). This integration of on-premises and public cloud resources is the definition of a hybrid cloud deployment.
D
Distractor review
Community cloud
Incorrect. A community cloud is shared by several organizations with common concerns (e.g., compliance). This scenario involves only a single organization using both on-premises and public cloud, not a multi-organization shared cloud.
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 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.

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: Hybrid cloud — This scenario describes a hybrid cloud deployment model because it combines on-premises infrastructure (private cloud or traditional datacenter) with a public cloud (Azure). The hospital retains sensitive data on-premises while leveraging the public cloud for other workloads. In contrast, a public cloud model would have everything in Azure, a private cloud would have no public cloud usage, and a community cloud involves multiple organizations with shared concerns.
