AZ-900 Practice Question 21: Hybrid Cloud Use Case
Microsoft Azure Fundamentals (AZ-900) · Test 3 · question 1 of 10
A hospital is legally required to keep patient records on servers it owns and controls. It also wants to host its public appointment-booking site in Azure and to add temporary Azure capacity during the annual flu surge. Which approach matches those requirements?
Show answer and explanation
Answer:
A hybrid cloud is a computing environment that uses both public and private clouds in an interconnected environment. Microsoft names two hybrid uses that match this stem exactly: letting a private cloud surge for increased, temporary demand by deploying public cloud resources, and choosing flexibly which services stay private for security, compliance, or legal reasons. The hospital gets Azure's elasticity for the booking site while the regulated records never leave its own hardware.
Option A breaks the legal requirement the moment the records are copied to Azure. Option B keeps the records compliant but gives up everything the hospital wanted from Azure; it would have to buy and maintain enough hardware to cover the flu peak all year round. Option D describes multicloud, which means dealing with two or more *public* cloud providers; adding a second public provider neither keeps records on owned servers nor creates a path to burst from private to public.
