AZ-900 Practice Test Questions

Q1: Azure Monitoring and Management

Imagine you have multiple resources running in Azure and you want to gather all their event logs into one single, central location for tracking and analysis. Which Azure service is designed specifically for this purpose?

Check Answer
Explanation: The correct answer is Azure Log Analytics.

Azure Log Analytics is the perfect tool for this job. It acts as a centralized workspace where you can collect, combine, and analyze log data from various sources (like Virtual Machines, applications, and other Azure services). Once the data is in this central repository, you can use a powerful query language (Kusto Query Language - KQL) to correlate events, find patterns, and troubleshoot issues across your entire cloud environment.

Why are the other options incorrect?
Azure Event Hubs: This is a big data streaming platform. It is designed to receive and process millions of events per second in real-time (like telemetry data from IoT devices). It is an ingestion service, not a centralized storage repository for querying logs.
Azure Analysis Services: This is an enterprise-grade data modeling engine used mainly for Business Intelligence (BI) and integrating with tools like Power BI.
Azure Monitor: This can be a bit tricky! While Azure Monitor is the overarching service that oversees the performance and health of your Azure environment, it actually uses a Log Analytics workspace as its underlying database to store and correlate those logs. Therefore, Log Analytics is the specific service/repository you are looking for.

Q2: Azure Management Tools

Imagine you are an Azure administrator, and you have written a PowerShell script intended to deploy several new Azure resources. You choose to execute this script from an Apple computer running macOS, which has PowerShell Core 6.0 installed. Will this specific setup allow you to successfully run the script and create the Azure resources?

Check Answer
Explanation: The correct answer is Yes.

Historically, people thought of PowerShell as a "Windows-only" tool. However, Microsoft made a huge shift by introducing PowerShell Core (starting from version 6.0). PowerShell Core is open-source and built on the cross-platform .NET Core. This means it is natively supported on macOS and Linux, as well as Windows! Because of this, you can easily install the Azure Az PowerShell module on a Mac, connect to your Azure account, and run scripts to build or manage resources without any issues.

Why might someone mistakenly choose "No"? (The trick):
Many beginners assume that because Azure is a Microsoft product, you absolutely need a Windows machine to run PowerShell scripts. While the older "Windows PowerShell" (versions 5.1 and below) was indeed restricted to Windows, "PowerShell Core" broke those boundaries. Microsoft's cloud approach is highly inclusive of developers using macOS or Linux environments.

Q3: Azure Security

Your company has requested a security setup for its Azure environment. You need to deploy a solution that achieves two main objectives: it must actively defend your hosted websites against malicious traffic, and it must provide detailed analytical reports about those attack attempts. Which of the following Azure features is the most appropriate choice for this requirement?

Check Answer
Explanation: The correct answer is Azure DDoS protection.

Azure DDoS (Distributed Denial of Service) Protection is specifically built to defend your web applications and services from being overwhelmed by fake, malicious traffic. What makes it the exact answer for this question is the "reporting" requirement. The standard tier of Azure DDoS Protection provides rich attack analytics, mitigation reports, and real-time alerts through Azure Monitor every time an attack is detected and blocked.

Why are the other options incorrect?
Azure Firewall: While it is a highly secure, cloud-native network firewall service that protects your Virtual Network resources, it is a broader network security tool. It doesn't automatically generate the specific "website attack reports" in the context this question implies.
Network Security Group (NSG): Think of an NSG as a simple bouncer at the door. It only checks basic rules (like IP addresses and port numbers) to allow or deny traffic. It does not inspect traffic for web attacks, nor does it generate intelligent attack reports.
Azure Information Protection (AIP): This is a data-level security tool. It is used to classify, label, and encrypt documents and emails (like making sure a confidential Word document can't be opened by outsiders). It has absolutely nothing to do with protecting websites from network attacks.

Q4: Azure Service Lifecycle

Review the three statements below regarding Azure services in Preview. Determine whether each statement is Yes (True) or No (False):

1. To access any Azure service that is currently in a Private Preview, you are required to log into a completely different, dedicated Azure Portal.

2. It is fully supported to deploy and run Azure services that are in Public Preview within your live production environments.

3. Microsoft guarantees a formal Service Level Agreement (SLA) for all services operating in Public Preview.

Check Answer
Explanation:

Statement 1 is False (No): You do not need a completely separate portal for Private Preview services. When you are accepted into a Private Preview, Microsoft enables the feature directly on your specific Azure Subscription. You simply log into the standard Azure Portal (portal.azure.com), and the new feature will be visible to you.

Statement 2 is False (No): Public Previews are released specifically for testing, evaluation, and gathering user feedback. Microsoft explicitly states that preview features are not meant for production environments as they may have limited features or undergo breaking changes before General Availability (GA).

Statement 3 is False (No): Golden Rule for the AZ-900 Exam: Preview features do NOT come with any Service Level Agreement (SLA). Formal SLAs and financial uptime guarantees are only provided once a service reaches General Availability (GA).

Q5: Shared Responsibility Model (Multiple Choice)

Understanding the Shared Responsibility Model is a must for the AZ-900 exam. When a company adopts the Infrastructure-as-a-Service (IaaS) cloud model, which two physical components are strictly the responsibility of the cloud service provider (e.g., Microsoft) to manage and maintain? (Select 2)

Check Answer
Explanation: The correct answers are The configuration and maintenance of storage and Maintaining the hardware.

The easiest way to understand IaaS is to think of it as "renting physical data center space." In this model, the cloud provider (Microsoft Azure) is completely responsible for the underlying physical foundation. This means they must ensure that physical servers (maintaining the hardware - Option C) are powered on, cooled, and running smoothly. They are also responsible for the physical hard drives and storage arrays in their data centers (configuration and maintenance of physical storage - Option A). As a customer, you never have to touch a physical server or replace a broken drive.

Why are the other options incorrect?
The installation and configuration of the operating system: In an IaaS model (like provisioning an Azure Virtual Machine), the Operating System is strictly your responsibility. The customer must install security patches, manage OS updates, and configure settings. The cloud provider does not manage the OS in IaaS.
The network configuration: While Microsoft manages the physical fiber cables and switches, the actual "network configuration" (creating Virtual Networks, subnets, routing tables, and firewall rules) falls under the customer's responsibility.

Q6: Cloud Economics (CapEx vs OpEx)

Understanding the difference between Capital Expenditure (CapEx) and Operational Expenditure (OpEx) is crucial in Azure. Review the three financial scenarios below and determine if they correctly describe an Operational Expenditure (OpEx) cost model:

1. Constructing a brand-new physical data center is considered an Operational Expenditure (OpEx).

2. Paying ongoing monthly wages to your technical IT staff falls under Operational Expenditure (OpEx).

3. Subscribing to or leasing software on a recurring basis is classified as an Operational Expenditure (OpEx).

Check Answer
Explanation:

Statement 1 is False (No): Building a data center requires a massive upfront capital investment (purchasing land, construction, hardware, and cooling systems). This large upfront purchase of physical infrastructure is the definition of CapEx (Capital Expenditure), not OpEx.

Statement 2 is True (Yes): Operational expenses represent the day-to-day ongoing costs of running a business. Paying IT personnel ongoing monthly salaries is a regular operational cost, perfectly fitting the definition of OpEx.

Statement 3 is True (Yes): Leasing software (such as subscribing to SaaS solutions like Microsoft 365) means paying recurring subscription fees instead of buying permanent licenses upfront with a large one-time payment. This shifts the expense into an ongoing OpEx model.

Q7: Azure Networking and Routing

You manage an Azure environment running several Virtual Machines (VMs). Your team needs one specific machine, "VM1", to host a web page. Your task is to make sure VM1 is openly accessible from the public Internet via standard HTTP traffic. To achieve this, you decide to modify the settings of an Azure Traffic Manager profile. Does this action successfully accomplish your goal?

Check Answer
Explanation: The correct answer is No.

Why does this NOT meet the goal?
Azure Traffic Manager is a DNS-based traffic load balancer. Its primary function is to distribute incoming client requests to optimal endpoints across global Azure regions based on routing methods (such as latency, priority, or geography). It operates at the DNS layer. It does not open network ports, route direct packets, or bypass security rules. If the network port on the VM is closed, Traffic Manager will simply direct users to an unreachable endpoint.

What is the CORRECT way to solve this?
To allow external HTTP traffic to reach VM1 from the public internet, you must:
1. Ensure VM1 has a Public IP address assigned directly or sits behind an Azure Public Load Balancer / Application Gateway.
2. Configure an Inbound Security Rule inside the Network Security Group (NSG) associated with VM1’s subnet or network interface, explicitly allowing traffic on destination Port 80 (HTTP).

Q8: Cloud Economics

Your organization currently operates a large on-premises data center containing 1,000 virtual machines running on physical Hyper-V servers. Management has decided to modernize the infrastructure by migrating all of these virtual machines into the cloud using an Azure "pay-as-you-go" subscription. From a financial and accounting perspective, which expenditure model will you be adopting with this new Azure setup?

Check Answer
Explanation: The correct answer is Operational (OpEx).

When operating an on-premises data center, a company must purchase physical servers, storage arrays, networking gear, and cooling systems upfront. By migrating to an Azure pay-as-you-go subscription, you eliminate the need to purchase physical hardware. Instead, you pay an ongoing operational bill based strictly on the resources you consume. This shift from an upfront investment to ongoing day-to-day business operational expenses represents the transition to an Operational Expenditure (OpEx) model.

Why are the other options incorrect?
Capital (CapEx): This represents the traditional on-premises model. Purchasing physical Hyper-V servers upfront was a Capital Expenditure. The company is migrating away from this model.
Elastic & Scalable: While Elasticity and Scalability are fundamental benefits of cloud computing, they describe technical infrastructure capabilities, not accounting or expenditure models.

Q9: Azure Management Tools

An Azure administrator has authored a script specifically written in PowerShell to automate the deployment of various Azure resources. You need to recommend a compatible computer setup to execute this script. Someone suggests the following solution: "Run the script from a computer running Linux that has the Azure CLI tools installed." Does this proposed setup allow you to successfully run the PowerShell script?

Check Answer
Explanation: The correct answer is No.

Why is the solution INCORRECT?
This is a classic exam trap. Pay close attention to the specific tools mentioned in the scenario. The administrator wrote a PowerShell script (which uses PowerShell cmdlets such as New-AzResourceGroup). However, the suggested machine only has Azure CLI installed.

Azure CLI and Azure PowerShell are two completely separate command-line toolsets. Azure CLI commands start with az and are typically executed within Bash or the Command Prompt. A computer with only Azure CLI installed lacks the PowerShell runtime and the Az module required to parse and execute PowerShell syntax.

How could this solution work?
• The Linux machine would need PowerShell Core (PowerShell 7) and the Azure Az module installed.
• OR the script would need to be rewritten in Bash using Azure CLI (az) commands instead of PowerShell cmdlets.

Q10: Azure Pricing and Billing

Review the three statements below regarding Azure's consumption-based (pay-as-you-go) pricing model. Determine whether each statement accurately describes how this model works (Answer Yes or No):

1. Under a consumption-based pricing model, you are charged a single, fixed flat rate for any network data that travels into or out of your cloud virtual machines.

2. A key benefit of a consumption-based model is cost reduction, as it allows you to pay exclusively for additional computing capacity only when your workload actually demands it.

3. Serverless computing architectures (like Azure Functions) perfectly illustrate a consumption-based pricing model.

Check Answer
Explanation:

Statement 1 is False (No): In Azure, network data transfer costs are variable and metered per gigabyte (GB). Ingress data (data coming into Azure) is typically free, whereas Egress data (data leaving Azure to the internet) is billed based on bandwidth consumption. It is never a fixed flat rate.

Statement 2 is True (Yes): The primary financial advantage of a consumption-based model is cost optimization through elastic auto-scaling. Instead of paying for peak capacity that sits idle, you dynamically scale compute resources and only pay for the extra capacity while the demand exists.

Statement 3 is True (Yes): Serverless computing (such as Azure Functions on a Consumption plan) is the quintessential example of consumption-based billing. You do not pay for idle server infrastructure; you are billed strictly for execution time and memory consumed per event trigger. If your code does not run, you pay $0.

Q11: Azure Compute Pricing

Microsoft Azure data centers often have excess, unused computing power sitting idle. To avoid wasting this, Azure offers a specific service that allows you to tap into this leftover capacity at massive discounts (sometimes up to 90% off the regular price). Which of the following services fits this exact description?

Check Answer
Explanation: The correct answer is Azure Spot Virtual Machine Instances.

Azure Spot VMs allow you to purchase Microsoft's unused compute capacity at significant discounts (often up to 90% compared to standard pay-as-you-go rates). However, there is an important trade-off: whenever Azure requires that capacity back for full-paying workloads, your Spot VM instance will be evicted (shut down) with minimal advance notification. As a result, Spot VMs are ideal for interruptible, non-critical workloads such as batch processing, big data analysis, dev/test environments, and video rendering.

Why are the other options incorrect?
Azure Reserved Virtual Machine Instances: This is the biggest distractor on the exam. While Reserved Instances also offer steep discounts (up to 72%), they require an upfront contractual commitment of 1 or 3 years for predictable, guaranteed capacity—not interruptible spare capacity.
Azure Container Instances (ACI): A serverless PaaS compute service used to quickly run Docker containers on demand without managing virtual machine infrastructure.
Azure Virtual Machine Scale Sets (VMSS): A management and scaling service that deploys an identical pool of auto-scaling, load-balanced virtual machines to maintain high availability.

Q12: Azure Storage Pricing & Data Transfer

Review the three claims below regarding Azure Storage billing and data transfer costs. Determine whether each statement is Yes (True) or No (False):

1. The monthly cost of holding 1 Terabyte (TB) of data inside Azure Blob Storage is exactly the same, no matter which global Azure Region you choose to host it in.

2. When using a standard General-Purpose v2 Storage Account, your bill is strictly based on the sheer volume of data you store. Any read or write transactions performed on that data are completely free of charge.

3. Moving your data from a storage account located in one Azure Region to another storage account in a completely different Azure Region does not incur any network transfer fees.

Check Answer
Explanation:

Statement 1 is False (No): Azure pricing is region-specific. Because the cost of real estate, taxes, local operations, and electricity varies globally, storing 1 TB in high-cost regions (such as Switzerland North) carries a different rate compared to lower-cost regions (such as East US).

Statement 2 is False (No): Azure Storage billing is multi-dimensional. Aside from capacity storage per GB, you are also billed for operational transactions (e.g., read, write, and list operations metered per 10,000 requests). High-activity applications generate significant transaction charges.

Statement 3 is False (No): While data transfer within the same Azure region is generally free, transferring data between two different geographic regions relies on Microsoft's global fiber-optic backbone and is billed as cross-region outbound data transfer (Egress bandwidth).

Q13: Security, Privacy, and Compliance

Review the three statements below regarding the Microsoft Service Trust Portal and Compliance Manager. Determine whether each claim is Yes (True) or No (False):

1. You can log into the Microsoft Service Trust Portal using your standard Microsoft cloud services credentials (such as your Azure AD / Microsoft Entra ID account).

2. The Compliance Manager tool is specifically designed to help your organization monitor, track, and improve its regulatory compliance posture when using Microsoft cloud services.

3. Inside the Microsoft Service Trust Portal, there is a feature called "My Library" that allows you to bookmark and store specific compliance documents in one convenient, centralized location.

Check Answer
Explanation:

Statement 1 is True (Yes): The Microsoft Service Trust Portal (STP) provides access to independent third-party audit reports (such as SOC, ISO, and FedRAMP certificates). To download and access confidential compliance documentation, you authenticate directly using your existing organizational Microsoft account (Entra ID / Azure AD).

Statement 2 is True (Yes): Microsoft Purview Compliance Manager is an end-to-end risk management and compliance tool. It provides a calculated "Compliance Score" measuring your organization's alignment with international regulatory frameworks (like GDPR, HIPAA, and ISO 27001) while delivering step-by-step guidance to improve your overall compliance posture.

Statement 3 is True (Yes): The "My Library" feature inside the Service Trust Portal allows compliance officers and security teams to save, bookmark, and track frequently referenced audit reports and whitepapers in a centralized repository with automated update alerts.

Q14: Azure Pricing & Support Plans

Evaluate the underlined segment in the statement below:

"The Azure Standard support plan is the cheapest tier available that provides you with round-the-clock (24/7) technical support from Microsoft engineers over the phone."

If the statement is correct, select "No change is needed." If it is incorrect, select the option that makes the statement true.

Check Answer
Explanation: The correct answer is No change is needed.

The statement is 100% accurate as written. The Standard support plan (starting at ~$100/month) is the entry-level tier that unlocks 24/7 technical support access via phone and email for production workloads.

Why are the other support plans incorrect?
Basic: While it is completely free, it provides zero technical support. It is strictly limited to billing, subscription management, and service health dashboards.
Developer: Cheaper (~$29/month), but intended strictly for trial and non-production testing. It only provides technical support via email during standard local business hours and does not include 24/7 phone access.
Professional Direct: While ProDirect includes 24/7 phone support and architectural guidance, it is significantly more expensive (~$1,000/month) and is designed for business-critical enterprise workloads.

Q15: Shared Responsibility Model

When an organization adopts a Software-as-a-Service (SaaS) solution (such as Microsoft 365), the management workload is divided between the customer and the cloud provider. According to the Azure Shared Responsibility Model, which of the following components is actively shared between you and Microsoft?

Check Answer
Explanation: The correct answer is Identity and directory infrastructure management.

In a SaaS architecture, identity management is a collaborative, shared responsibility. Microsoft provides, scales, and protects the underlying directory platform (such as Microsoft Entra ID). However, the customer remains responsible for configuring tenant access: provisioning user credentials, enabling Multi-Factor Authentication (MFA), establishing Role-Based Access Control (RBAC), and setting conditional access policies.

Why are the other options incorrect?
Application management: In SaaS, the software vendor (Microsoft) develops, maintains, patches, and manages the entire application stack. You simply access the software as an end-user.
Information and data management: Universal Cloud Rule: Regardless of whether you use IaaS, PaaS, or SaaS, data classification, governance, and ownership always remain 100% the customer's responsibility.
Operating system updates: In SaaS, the underlying infrastructure, virtualization layer, and guest operating systems are completely abstracted away and managed 100% by Microsoft.

Q16: Cloud Service Models (IaaS, PaaS, SaaS)

Review the three statements below regarding IaaS, PaaS, and SaaS service models. Determine whether each statement is Yes (True) or No (False):

1. When utilizing a Software-as-a-Service (SaaS) product, it is your responsibility as the customer to manually download and apply software updates or patches.

2. When you deploy an Infrastructure-as-a-Service (IaaS) solution, you are required to manually install any specific applications or software that you wish to use on that infrastructure.

3. The "Azure Backup" service is technically categorized as a Platform-as-a-Service (PaaS) offering.

Check Answer
Explanation:

Statement 1 is False (No): A defining benefit of SaaS (like Microsoft 365 or Gmail) is that software maintenance is completely abstracted. The vendor manages the application codebase, patches, security fixes, and feature updates. Users simply sign in and access the latest software version automatically.

Statement 2 is True (Yes): In an IaaS deployment (such as an Azure Virtual Machine), the cloud provider delivers physical hosts, storage, and the hypervisor layer. Once the virtual machine is provisioned, configuring and installing custom applications, database engines, or web servers is entirely the customer's responsibility.

Statement 3 is True (Yes): Azure Backup is categorized as a PaaS service. Customers do not provision, configure, or maintain dedicated backup servers or physical storage arrays. Microsoft provides the underlying backup management platform, and you simply define backup policies and retention schedules.

Q17: Cloud Service Types (IaaS vs PaaS)

Your IT team is preparing to deploy a new environment in the cloud. The architecture requirements strictly state that you must use an Infrastructure-as-a-Service (IaaS) model so that your team has full control over the operating system. Which of the following Azure resources is a classic example of an IaaS product?

Check Answer
Explanation: The correct answer is An Azure Virtual Machine.

An Azure Virtual Machine (VM) is the fundamental example of Infrastructure-as-a-Service (IaaS). When you provision a VM, Microsoft provides the virtualized compute, storage, and networking capacity while you retain total control over the guest Operating System. You manage OS-level firewall rules, apply patches, configure services, and connect via RDP (Windows) or SSH (Linux).

Why are the other options incorrect?
All other options (A, C, and D) are categorized as Platform-as-a-Service (PaaS):
Azure Web App (App Service): PaaS web hosting where Microsoft manages the underlying OS and runtime environment. You simply deploy application code.
Azure Logic App: Serverless PaaS workflow orchestration tool used to integrate enterprise applications and APIs visually without managing servers.
Azure SQL Database: A fully managed relational Database-as-a-Service (PaaS). Microsoft automates OS patching, high availability, and database engine maintenance.

Q18: SaaS Management Responsibilities

Your organization has just purchased subscriptions for a Software-as-a-Service (SaaS) application, such as Microsoft 365. As the IT administrator rolling out this product, what is your primary technical responsibility?

Check Answer
Explanation: The correct answer is Configuring the SaaS solution.

Although a SaaS application is developed, hosted, patched, and managed by the cloud vendor, the customer remains responsible for tailoring the software to their business needs. Configuration tasks include provisioning user accounts, setting up security permissions, defining data sharing rules, configuring organization-specific workflows, and enabling/disabling application features.

Why are the other options incorrect?
Configuring high availability & Defining scalability rules: In SaaS, infrastructure resiliency and auto-scaling are managed 100% by the cloud provider. Microsoft guarantees the application SLA and dynamically scales backend compute power without customer intervention.
Installing the SaaS solution: SaaS applications are centrally hosted in the cloud. There is no server-side deployment or manual infrastructure installation required; users simply access the software through a web browser or mobile client.

Q19: Azure Core Services & AI (Matching)

Match each description below to its corresponding Azure Service:

1. Provides a digital online assistant that provides speech and conversational support:

2. Uses past trainings to provide predictions that have high probability:

3. Provides serverless computing functionalities:

4. Processes telemetry data from millions of connected sensors and devices:

Check Answer
Explanation:

Description 1 matches Azure AI Bot: Whenever an exam question highlights "digital assistant," "conversational agents," or "speech/chat support," think of Azure Bot Services (Azure AI Bot). It enables developers to build virtual conversational assistants that interact naturally with users via text or voice.

Description 2 matches Azure Machine Learning: Machine learning is fundamentally about analyzing historical data ("past trainings") to detect patterns and generate predictive models ("predictions with high probability"). Azure Machine Learning provides the cloud workspace to build, train, and deploy these models.

Description 3 matches Azure Functions: Azure Functions is Microsoft's primary Serverless compute service. It executes code blocks (functions) on demand in response to triggers and events, scaling compute power automatically without requiring server management.

Description 4 matches Azure IoT Hub: "IoT" stands for Internet of Things. If a scenario involves smart appliances, embedded hardware, or "millions of sensors" transmitting real-time telemetry data to the cloud, Azure IoT Hub is the central managed messaging hub for bi-directional device communication.

Q20: High Availability & Disaster Recovery (Multiple Choice)

Imagine you are designing the architecture for a critical application running on several Azure Virtual Machines. Your main requirement is fault tolerance: the application must remain online even if an entire physical Microsoft data center goes offline (e.g., due to a major power failure or disaster). Which two deployment strategies from the list below will successfully meet this requirement? (Select 2)

Check Answer
Explanation: The correct answers are Deploy the virtual machines to two or more Availability Zones and Deploy the virtual machines to two or more Azure Regions.

To protect workloads from an entire physical datacenter failure, resources must be physically separated:
Availability Zones (Option C): Within an Azure Region, Microsoft operates multiple isolated physical datacenters (Zones) with independent power, cooling, and network links. If Datacenter 1 experiences a failure, Datacenter 2 in a different zone remains operational.
Azure Regions (Option D): Provides geographic disaster recovery. Distributing workloads across separate geographic regions (e.g., East US and West Europe) protects services against regional catastrophes.

Why are the other options incorrect?
Deploying to different Resource Groups: A Resource Group is strictly a logical management container for access control, governance, and billing. It has zero impact on physical server placement.
Deploying to a standard Scale Set: Virtual Machine Scale Sets (VMSS) provide automated compute elasticity and scaling, but a default scale set does not guarantee multi-datacenter survival unless explicitly configured as zone-redundant across multiple Availability Zones.
