A civic open-data team asks which three cloud models AZ-900 expects them to name. Which set is correct?
Select an answer to reveal the explanation.
Short Explanation
Write these three on the whiteboard: public, private, hybrid. IaaS/PaaS/SaaS are service types, not the model trio. Regions and resource groups are Azure organizing ideas, not those three models.
Full Explanation
AZ-900’s primary cloud models are public, private, and hybrid. That trio describes how cloud capacity is owned and combined across organizational boundaries. Civic teams should memorize those three names separately from service types and from Azure resource-organization concepts.
Listing IaaS, PaaS, and SaaS as the cloud models confuses service types (how much stack the provider manages) with deployment models. CapEx, OpEx, and “hybrid financing” describe spending patterns, not the three cloud models. Regions, availability zones, and resource groups are Azure geographic and organizational constructs, not substitutes for public/private/hybrid.
Exam caveat: questions sometimes mix vocabulary on purpose; map each term to its category before answering. Operational check: in an open-data architecture brief, include a one-line model choice (public, private, or hybrid) and a separate line for service type (IaaS/PaaS/SaaS) so stakeholders do not treat them as interchangeable labels. A useful study habit is to place each buzzword in a bucket: models (public/private/hybrid), service types (IaaS/PaaS/SaaS), commercial patterns (CapEx/OpEx/consumption), and Azure structure (regions, availability zones, resource groups). Mixing buckets is how easy exam points are lost.
