Free Microsoft Azure Fundamentals (AZ-900) practice test

Microsoft Azure Fundamentals (AZ-900) proves you can describe cloud concepts, core Azure architecture and services, and the tools Azure gives you for management and governance. This site gives you 285 original questions plus 12 drag-and-drop and build-list items in Microsoft's own interactive formats, free and without an account.

The simulator runs 45 timed minutes on the real scale (pass line 700 of 1,000), grades interactive items all-or-nothing the way Microsoft does, and links every topic to the matching video in John Savill's free per-topic AZ-900 course.

Practice questions from this bank

Sample question 1 · AZ-900 · Describe cloud concepts

A new hire on the IT team asks what cloud computing actually is. Which description is accurate?

  1. ARunning virtual machines on hypervisors in a company-owned datacenter
  2. BOutsourcing hardware repairs to a nearby colocation facility
  3. CDelivering computing services such as servers and storage over the internet
  4. DStreaming desktop applications from a server on the office network
Show answer and explanation

C. Delivering computing services such as servers and storage over the internet

Cloud computing is the delivery of computing services, including servers, storage, databases, and networking, over the internet with pay-as-you-go pricing. The other options describe on-premises or colocation arrangements where the organization still owns and operates the underlying infrastructure.

Topic: John Savill: High Availability and Scalability

Sample question 2 · AZ-900 · Describe Azure architecture and services

Which statement most accurately describes an Azure region?

  1. AOne or more datacenters connected through a low-latency network within a geographic area
  2. BA billing construct that groups subscriptions by the currency used for invoicing
  3. CA logical container used to group virtual machines that share the same lifecycle
  4. DA physically separate location within an Azure region with independent power, cooling, and networking
Show answer and explanation

A. One or more datacenters connected through a low-latency network within a geographic area

A region is one or more datacenters placed within a latency-defined perimeter and linked by a dedicated low-latency network. The isolated-location description fits an availability zone, and lifecycle grouping describes a resource group.

Topic: John Savill: Regions and Region Pairs

Sample question 3 · AZ-900 · Describe Azure management and governance

A team deploys identical D4s v5 virtual machines to two different Azure regions and notices the monthly compute charge differs between them. What explains the difference?

  1. AA reservation discount was applied automatically in one region
  2. BBandwidth egress charges are folded into the compute meter
  3. CMeter rates for the same VM size differ from region to region
  4. DOne region's hardware generation carries a billing surcharge
Show answer and explanation

C. Meter rates for the same VM size differ from region to region

Azure prices each meter per region, so the same VM size can cost more where local infrastructure and energy are pricier. Reservations are only applied after you purchase them, and egress is billed on its own networking meters rather than inside compute.

Topic: John Savill: Factors That Affect Costs

Sample question 4 · AZ-900 · Describe cloud concepts

A newly funded startup cannot justify large upfront infrastructure purchases but expects rapid, uneven growth. Which financial characteristic of the public cloud most directly addresses this situation?

  1. AHardware costs are depreciated over a fixed multi-year schedule
  2. BInfrastructure capacity is purchased in advance at a discount
  3. CInfrastructure is paid for as an operating expense as it is used
  4. DSpending is locked to a flat rate regardless of monthly usage
Show answer and explanation

C. Infrastructure is paid for as an operating expense as it is used

Public cloud shifts infrastructure from capital purchases to operating expenses that track actual usage, so a startup can begin small and grow without a big initial outlay. Depreciation schedules and advance capacity purchases are traits of the on-premises capital model.

Topic: John Savill: CapEx, OpEx, and Consumption-Based

Sample question 5 · AZ-900 · Describe Azure architecture and services

An IT department wants a clear line where usage charges are aggregated onto a single invoice. Which level of the Azure hierarchy provides this?

  1. AManagement group
  2. BSubscription
  3. CResource group
  4. DResource
Show answer and explanation

B. Subscription

Billing is scoped to the subscription: usage across all its resources is aggregated and invoiced at that level. Management groups organize subscriptions for governance, but invoices are not generated there.

Topic: John Savill: Subscriptions

Sample question 6 · AZ-900 · Describe Azure management and governance

Finance asks which service consumed the most spend last month and how the total trended by resource group. Where can this breakdown be viewed?

  1. ACost analysis in Microsoft Cost Management
  2. BThe Azure pricing calculator
  3. CAzure Service Health
  4. DMetrics explorer in Azure Monitor
Show answer and explanation

A. Cost analysis in Microsoft Cost Management

Cost analysis breaks accrued spend down by service, resource group, region, tag, and time, which answers both questions directly. The pricing calculator only forecasts future configurations and has no view of what a subscription actually spent.

Topic: John Savill: Azure Cost Management

Sample question 7 · AZ-900 · Describe cloud concepts

An operations lead notes that load balancing and autoscaling keep response times consistent for users even during sudden demand spikes. Which cloud benefit is being described?

  1. ACost predictability
  2. BPerformance predictability
  3. CShared responsibility
  4. DVertical scalability
Show answer and explanation

B. Performance predictability

Performance predictability means users get a consistent experience because capacity adjusts and traffic is distributed as demand changes. Cost predictability concerns forecasting spend, which load balancing does not address.

Topic: John Savill: Reliability and Predictability

Sample question 8 · AZ-900 · Describe Azure architecture and services

An engineering group operates about 40 containerized microservices that need automated placement, self-healing, rolling upgrades, and scaling across a shared pool of compute. Which service is purpose-built for orchestrating this workload?

  1. AAzure Container Instances
  2. BAzure Kubernetes Service
  3. CAzure App Service
  4. DAzure Functions
Show answer and explanation

B. Azure Kubernetes Service

Azure Kubernetes Service delivers managed Kubernetes, whose core job is orchestration: scheduling containers onto nodes, restarting failed ones, and rolling out upgrades across a fleet. Azure Container Instances runs containers one at a time and lacks the scheduling and self-healing features a large microservice estate needs.

Common questions

How many questions are on the AZ-900 exam?

Typically 40 to 60 questions with about 45 minutes of exam time. Most are multiple choice and multiple select, with occasional drag-and-drop and build-list items. Passing requires 700 on a scale up to 1,000.

Does AZ-900 expire?

No. Fundamentals certifications like AZ-900 don't expire, so it's a one-time investment that stays on your transcript.

What does AZ-900 cover?

Three skill areas: cloud concepts (25-30%), Azure architecture and services (35-40%), and Azure management and governance (30-35%). Every topic here links to the matching video in John Savill's free AZ-900 course.
