A company keeps sensitive customer data on on-premises servers but bursts web traffic to Azure during peak periods, with both environments connected and managed together. Which model is this?
A.Public cloud
Public-only would mean no on-premises infrastructure — the scenario explicitly keeps data on-premises.
B.Private cloud
Private-only wouldn't use Azure for bursting.
C.Hybrid cloud
Hybrid = on-premises + public cloud integrated as one environment. Correct.
D.Multi-cloud
Multi-cloud means using services from multiple public cloud providers — only Azure is used here.
Why this answer
Hybrid cloud interconnects on-premises (private) infrastructure with public cloud so workloads and data can move between them. It is a core AZ-900 definition — look for 'on-premises + cloud working together' in the stem.
