AZ-900 Practice Question 81: Public Cloud Startup Scenario
Microsoft Azure Fundamentals (AZ-900) · Test 9 · question 1 of 10
A three-person startup is building its first product. It owns no servers, wants to avoid any upfront hardware spend, and expects to scale from a handful of users to many thousands within weeks if the product takes off. Which cloud deployment model best fits these requirements?
Show answer and explanation
Answer:
A public cloud is built, controlled, and maintained by a third-party provider and made available to anyone who wants to buy compute, storage, or other resources; Microsoft describes this as requiring no capital expenditure, since you pay only for the resources you use. That is exactly the startup's situation: no servers owned, no data center to build, and the ability to scale capacity up or down as demand changes, which is the elasticity a public cloud is designed to provide.
Option B is wrong because a private cloud is dedicated to a single organization, and someone still has to buy and maintain that hardware, the opposite of avoiding upfront cost. Option C describes a hybrid cloud, which interconnects public and private environments; nothing in the stem requires keeping any workload on owned hardware. Option D describes multicloud, using two or more public providers at once; that adds operational complexity and is not what makes a single new product cheap to start or easy to scale.
