Microsoft AZ-900: Microsoft Azure Fundamentals

Last checked October 22, 2026 against the official Microsoft exam page.

1. Question 1Describe Azure architecture and services

   A company needs a container to run a small background job for a few minutes at a time without managing a cluster. Which Azure compute option fits best?

   1. AAzure Container Instances
   2. BAzure Kubernetes Service with a large permanent node pool
   3. CA dedicated physical server
   4. DAzure Virtual Desktop
   Show answer and explanationHide answer

   Correct answer: A

   Azure Container Instances runs containers on demand without managing a cluster, which suits short jobs. A permanent Kubernetes node pool is more than the job needs, a physical server requires management, and Virtual Desktop serves user desktops.

2. Question 2Describe Azure management and governance

   A company wants to see what it spent on Azure last month, broken down by department, and to set alerts when spending approaches a limit. Which tool should it use?

   1. AAzure Cost Management and Billing
   2. BAzure Resource Graph
   3. CAzure Bastion
   4. DAzure Service Health
   Show answer and explanationHide answer

   Correct answer: A

   Cost Management and Billing reports spending, supports breakdowns by tags or scopes, and can send budget alerts. Resource Graph queries resource properties, Bastion provides remote access, and Service Health reports platform issues.

3. Question 3Describe cloud concepts

   A company wants to move from buying and maintaining its own servers to paying only for the compute it uses each month. Which cloud model describes this change?

   1. AHybrid ownership of physical data centres
   2. BCapital expenditure with a fixed hardware purchase
   3. COn-premises perpetual licensing
   4. DOperational expenditure replacing capital expenditure
   Show answer and explanationHide answer

   Correct answer: D

   Consumption-based billing turns large upfront hardware purchases into operating costs that follow usage. Capital expenditure and on-premises licensing describe the older model, and hybrid ownership still retains physical data centres.

4. Question 4Describe Azure architecture and services

   A team wants to run event-driven code that starts when a file is uploaded to a storage account, without provisioning servers. Which service is designed for this?

   1. AAzure Virtual Machines
   2. BAzure SQL Managed Instance
   3. CAzure Functions
   4. DAzure Backup
   Show answer and explanationHide answer

   Correct answer: C

   Azure Functions runs code in response to triggers such as storage events, without server provisioning. Virtual machines require management, SQL Managed Instance is a database service, and Backup protects data.

5. Question 5Describe Azure management and governance

   A company requires that all resources in its subscriptions have an owner tag. Non-compliant deployments should be blocked. Which service should be used?

   1. AAzure Advisor recommendations only
   2. BAzure Policy with a deny effect
   3. CA tag added manually after each deployment
   4. DAzure Service Health alerts
   Show answer and explanationHide answer

   Correct answer: B

   Azure Policy with a deny effect blocks resource deployments that do not meet the rule, such as a missing owner tag. Advisor makes recommendations without blocking, manual tags are not enforced, and Service Health reports platform status.
