AZ-900 Practice Question 92: Regulated Data with Burst Capacity
Microsoft Azure Fundamentals (AZ-900) · Test 10 · question 2 of 10
A hospital network must, by regulation, keep patient imaging data on servers under its own physical control at all times. Its billing and website teams also need extra compute capacity for a few weeks every year during open-enrollment season, and the network does not want to buy and maintain hardware that sits idle the rest of the year. Which deployment model satisfies both requirements?
Show answer and explanation
Answer:
A hybrid cloud interconnects a private environment with a public one, and Microsoft names this exact pairing of needs as a hybrid use case: letting a private environment surge into public cloud resources for temporary demand, while choosing to keep specific services private for legal or compliance reasons. Here the imaging data never leaves hardware the hospital controls, satisfying the regulation, while the billing and website teams get elastic Azure capacity only when the enrollment surge needs it, no idle hardware sitting around the rest of the year.
Option A fails the regulation the moment imaging data is copied into Azure Storage, regardless of how compliant that storage account is configured to be. Option C satisfies the regulation but throws away the second requirement: sizing private infrastructure for the annual peak means buying and maintaining that capacity year-round, which is exactly the idle-hardware cost the hospital wants to avoid. Option D describes multicloud, which means using two or more *public* cloud providers; splitting data between two public providers still moves it off hardware the hospital controls, so it fails the regulation just as badly as option A.
