Microsoft AZ-900 Exam 2026 – 190 Practice Questions with Answers
& Detailed Rationales, Cloud Concepts, Azure Architecture &
Services, Management, Governance, Security, Pricing & Support
SECTION 1: DESCRIBE CLOUD CONCEPTS (25–30%)
(Questions 1–50)
Question 1
A multinational corporation is evaluating cloud adoption. The CIO states: “We want to keep
our most sensitive patient records on our own hardware due to regulatory constraints, but
we need the elasticity of the cloud for our marketing website.” Which cloud deployment
model BEST describes this requirement?
A. Public cloud
B. Private cloud
C. Hybrid cloud
D. Community cloud
Correct Answer: C
Explanation: Hybrid cloud combines private infrastructure for sensitive workloads with
public cloud for scalable, less-regulated applications, satisfying both compliance and
elasticity needs.
Question 2
A startup has limited capital and unpredictable traffic patterns. They want to avoid large
upfront hardware purchases and pay only for what they consume monthly. Which cloud
benefit directly addresses this?
,A. High availability
B. Scalability
C. Consumption-based model
D. Governance
Correct Answer: C
Explanation: The consumption-based model shifts spending from capital expenditure
(CapEx) to operational expenditure (OpEx), eliminating upfront costs and charging only for
actual usage.
Question 3
In the shared responsibility model for a PaaS deployment, which responsibility ALWAYS
remains with the customer regardless of service model?
A. Physical datacenter security
B. Operating system patching
C. Data classification and accountability
D. Hypervisor maintenance
Correct Answer: C
Explanation: The customer always retains responsibility for their data, including
classification, protection, and compliance, while Microsoft handles physical and platform
layers.
Question 4
A company runs a private cloud but wants to burst to Azure during seasonal peaks without
re-architecting applications. Which cloud model should they adopt?
,A. Public cloud only
B. Hybrid cloud
C. Community cloud
D. Multi-cloud only
Correct Answer: B
Explanation: Hybrid cloud enables integration between on-premises private infrastructure
and public Azure, allowing seamless workload bursting during demand spikes.
Question 5
Which characteristic of cloud computing allows an application to continue operating during a
datacenter outage by automatically shifting traffic to another location?
A. Elasticity
B. High availability
C. Scalability
D. Predictability
Correct Answer: B
Explanation: High availability ensures continuous operation through redundancy and failover
mechanisms, minimizing downtime during infrastructure failures.
Question 6
A development team wants to deploy code without provisioning or managing servers. They
write functions that execute only when triggered by events. Which model are they using?
A. IaaS
, B. PaaS
C. SaaS
D. Serverless
Correct Answer: D
Explanation: Serverless computing abstracts server management entirely, executing code on-
demand and charging only for resources consumed during execution.
Question 7
Which scenario is the MOST appropriate use case for Infrastructure as a Service (IaaS)?
A. Sending email using Microsoft 365
B. Hosting a legacy application requiring custom OS configurations
C. Using a CRM system accessed via browser
D. Deploying code without managing operating systems
Correct Answer: B
Explanation: IaaS provides maximum control over virtual machines and operating systems,
ideal for legacy applications needing specific OS configurations or custom software.
Question 8
A university provides students with a cloud-based email and document editing suite
accessible through a browser. Which cloud service type is this?
A. IaaS
B. PaaS
C. SaaS
