AZ-900 is Microsoft's entry-level Azure certification, requiring a scaled score of 700 out of 1000 to pass. The exam gives you a 45-minute answering window (about 65 minutes of total seat time) and covers cloud concepts (25–30%), core Azure services (35–40%), and management/governance (30–35%); Microsoft does not publish the question count (most Microsoft exams have 40-60 questions). It costs $99 USD in the United States, is delivered through Pearson VUE (test center or online proctoring), and is widely recommended as the first step toward higher-level certifications like AZ-104 (Administrator) or AI-200 (Azure AI Cloud Developer, which replaced AZ-204 on July 31, 2026).

Sample Azure AZ-900 Practice Questions

1Which cloud computing characteristic ensures that resources can be increased or decreased quickly to match demand?
A.High availability
B.Elasticity
C.Fault tolerance
D.Disaster recovery
Explanation: Elasticity refers to the ability to automatically scale computing resources up or down based on workload demand. This is distinct from scalability (the ability to scale) in that elasticity implies the scaling happens dynamically and automatically. High availability ensures uptime, fault tolerance handles failures, and disaster recovery addresses major outages.
2A company is evaluating cloud models. They want full control over their infrastructure but also want the flexibility to burst workloads to a public cloud during peak periods. Which cloud model best fits this requirement?
A.Public cloud
B.Private cloud
C.Hybrid cloud
D.Community cloud
Explanation: A hybrid cloud combines private and public cloud environments, allowing organizations to keep sensitive workloads on-premises (private) while bursting to the public cloud during peak demand. This model provides control and flexibility simultaneously. A purely private cloud lacks burst capability, while a purely public cloud lacks the private control the company wants.
3Under the shared responsibility model in Azure, which of the following is ALWAYS the customer's responsibility, regardless of the cloud service model used?
A.Physical datacenter security
B.Network infrastructure maintenance
C.Operating system patching
D.Data and identity management
Explanation: Data and identity management remain the customer's responsibility across all service models (IaaS, PaaS, SaaS). Microsoft manages physical security in all cases. OS patching is managed by Microsoft in PaaS and SaaS but is the customer's responsibility in IaaS. Network infrastructure is generally a Microsoft responsibility. The customer always owns their data and is responsible for managing who has access to it.
4A startup wants to deploy a web application without managing servers, operating systems, or runtime environments. They pay only for the execution time of their code. Which compute approach matches this requirement?
A.Azure Virtual Machines (IaaS)
B.A Kubernetes cluster that the team manages
C.A ready-made SaaS application
D.Serverless computing, such as Azure Functions
Explanation: Serverless computing lets developers deploy code that runs only when an event triggers it. Microsoft manages the servers, and on a serverless plan you pay for executions rather than idle capacity. Azure Functions is Azure's main serverless option, and Microsoft lists Azure Functions as a PaaS service. Virtual machines are IaaS and leave the operating system to you, a Kubernetes cluster you manage still needs node and cluster upkeep, and a SaaS application is finished software you use rather than code you deploy.
5Which cloud service model gives customers the MOST control over the underlying infrastructure, including the operating system?
A.Infrastructure as a Service (IaaS)
B.Platform as a Service (PaaS)
C.Software as a Service (SaaS)
D.Database as a Service (DBaaS)
Explanation: IaaS provides the highest level of control, giving customers access to virtualized compute, storage, and networking resources. Customers manage the operating system, middleware, runtime, and applications. Azure Virtual Machines is a classic IaaS example. PaaS abstracts the OS, SaaS abstracts everything, and DBaaS abstracts the database engine itself.
6A company is replacing its capital expenditure (CapEx) model for IT infrastructure with a cloud-based approach. Which Azure pricing concept aligns with this transition?
A.Reserved capacity pricing
B.Consumption-based (operational expenditure) pricing
C.Fixed monthly pricing
D.Perpetual licensing
Explanation: Cloud computing shifts IT spending from capital expenditure (CapEx — large upfront hardware purchases) to operational expenditure (OpEx — pay-as-you-go based on consumption). In Azure, you pay only for the resources you use, with no upfront costs. This consumption-based model provides better cost predictability and eliminates the need to over-provision hardware.
7An organization requires that their application remain available even if an entire Azure region experiences a complete outage. Which cloud benefit directly addresses this requirement?
A.Scalability
B.Agility
C.Geo-redundancy / disaster recovery
D.Elasticity
Explanation: Geo-redundancy and disaster-recovery design can keep an application available after a regional outage by using resources and data in another region. A region pair can inform resiliency planning, but pairing alone does not make every service replicate or fail over automatically; the selected services and architecture must provide and configure those behaviors.
8Which statement BEST describes the difference between vertical scaling and horizontal scaling in cloud computing?
A.Vertical scaling adds more instances; horizontal scaling increases instance size
B.Vertical scaling increases the power of a single instance (more CPU/RAM); horizontal scaling adds more instances
C.Vertical scaling is used for compute; horizontal scaling is used for storage
D.They are identical concepts with different names
Explanation: Vertical scaling (scaling up) increases the compute power of an existing instance — for example, moving from a 2-core VM to an 8-core VM. Horizontal scaling (scaling out) adds more instances of the same resource — adding more VMs to handle load. Horizontal scaling is generally preferred in cloud architectures because it provides redundancy, while vertical scaling has hardware limits.
9A company uses Microsoft 365, which is hosted entirely by Microsoft. Users access the service via a web browser and do not manage servers, storage, or application updates. Which service model does this represent?
A.Infrastructure as a Service (IaaS)
B.Platform as a Service (PaaS)
C.Software as a Service (SaaS)
D.Function as a Service (FaaS)
Explanation: Software as a Service (SaaS) delivers a complete application over the internet that the provider runs. Microsoft 365 is a classic SaaS example — users access Word, Excel, Outlook, and Teams without managing servers, storage, or updates. The provider runs the application and infrastructure, while the company still manages its data, user accounts and access, devices, and service settings. Other SaaS examples include Salesforce and Dropbox.
10In the shared responsibility model, which party is responsible for the physical security of Azure datacenters?
A.The customer
B.Microsoft
C.Both Microsoft and the customer equally
D.A third-party security firm contracted by the customer
Explanation: Microsoft is always responsible for the physical security of Azure datacenters, including facilities, guards, cameras, and access controls. This responsibility never transfers to the customer regardless of the service model used. This is one of the key advantages of using cloud services — customers do not need to invest in physical security infrastructure.

Azure AZ-900: Suggested Study Strategy

1Focus on the Azure Services domain (35–40%) — memorize which service solves which problem (e.g., Azure Functions for serverless, Azure Blob for unstructured storage, Azure SQL for relational data)
2Distinguish IaaS operating-system control, PaaS application deployment, and SaaS configuration; customers remain responsible for their data and identities.
3Know the shared responsibility model: what Microsoft is always responsible for (physical datacenter, network, hosts) vs. what varies by service model
4Distinguish estimated costs in the pricing calculator from actual spending and budget alerts in Cost Management; use Advisor for optimization recommendations.
5Create a free Azure account and explore the portal — hands-on familiarity with the Azure portal UI makes governance questions much easier

Frequently Asked Questions

What is the AZ-900 passing score?

The Microsoft Azure Fundamentals (AZ-900) exam requires a passing score of 700 out of 1000. Microsoft does not publish the AZ-900 question count (most Microsoft Certification exams have 40–60 questions), and you get a 45-minute answering window (about 65 minutes of total seat time). Microsoft uses scaled scoring, so scores are reported on a 1–1000 scale and 700 may not equal 70% of the points. Candidates who score 700 or higher receive a passing result.

How hard is the AZ-900 exam?

AZ-900 is widely considered one of the easiest cloud certification exams. It tests foundational concepts — not hands-on technical skills — and has no formal prerequisites, though Microsoft's audience profile assumes some experience in an area of IT. A typical study plan is 1–3 weeks (10–20 hours). The main challenge is memorizing Azure service names and their use cases. Our free practice questions cover all three domains with detailed explanations.

How long should I study for AZ-900?

Plan on 1–3 weeks and about 10–20 hours total. Key study actions: 1) Review all three exam domains (Cloud Concepts, Azure Services, Governance). 2) Create a free Azure account to explore the portal hands-on. 3) Complete at least 100 practice questions. 4) Aim for 80%+ on practice tests before scheduling. Candidates with an IT background often pass after just 5–10 hours of focused review.

What jobs does AZ-900 qualify me for?

AZ-900 is a foundational certification — it demonstrates cloud awareness rather than technical expertise. It is ideal for: Business analysts, project managers, and sales professionals working with cloud teams; IT professionals beginning their cloud journey; students seeking to prove cloud knowledge to employers. It is not sufficient alone for technical Azure roles (those require AZ-104 or AZ-305).

What is the difference between AZ-900 and AZ-104?

AZ-900 (Azure Fundamentals) tests conceptual cloud knowledge — what services exist, pricing basics, and governance concepts. AZ-104 (Azure Administrator Associate) tests hands-on ability to manage Azure infrastructure, including VMs, storage, networking, identity, and security. AZ-104 expects hands-on experience and is significantly harder. AZ-900 is optional but useful for building the foundational vocabulary before attempting AZ-104.
