Azure Interview Questions and Answers

Ques1) What is Microsoft Azure?
Answer– Microsoft Azure is a cloud computing platform. Earlier, big companies had to purchase their own servers to store their data, set them up, and maintain them, which was very expensive and a hassle. Basically, Microsoft Azure has set up its large data centers all over the world. And through Azure, you can rent storage on the internet as much as you need. This saves you a lot of space and money.

 Microsoft storage 

In simple words, Microsoft is an online platform where you can store a lot of things like websites, applications, databases, software, etc., without the need for large computers or physical storage space.

Ques2) What is Azure Virtual Machine ?
Answer- Having your own computer in the cloud is what an Azure Virtual Machine (VM) is. Through Azure, Microsoft allows you to “rent” a virtual laptop or desktop in place of purchasing a real one. You can install any software you require, select the operating system it runs on (such as Windows or Linux), and determine how powerful it is.

It’s excellent for hosting websites, testing software, and running apps without requiring physical hardware management.

Because it’s a component of Infrastructure as a Service (IaaS), you control the rest while Microsoft provides the foundation (such as the server, storage, and network).

Ques3) What is Azure Kubernetes Service (AKS) ?
Answer- Azure Kubernetes Service (AKS) is a free managed service of Microsoft Azure that automatically deploys, manages, and scales your containers.

Imagine you have an app that is made up of small parts (like login, cart, payment) — you put them in containers. AKS smartly runs and controls all these containers.

  • You do not have to manually set up anything
  • The app is fast, secure, and scalable
  • Azure handles everything

Ques4) What is Azure SQL database ?
Answer- Azure SQL Database is a cloud-based database service that runs on Microsoft Azure. This is a system in which you can safely store your data (such as user info, orders, records) – without installing or maintaining a server. In this you get features like SQL Server, but everything happens online and Microsoft manages everything for you.

Ques5) What is Azure Active Directory (Azure AD) ?
Answer- Microsoft’s cloud-based identity and access management tool is Azure Active Directory, or Azure AD. Securely signing in helps consumers use tools including Microsoft 365, Azure portal, and other cloud apps. Azure AD is, all things considered, a technology that provides users safe login and app access.

For instance, Azure AD guarantees that, should you be employed by a company, you log in using the correct username-password and only access items dear to your heart, such as email, Teams, or SharePoint. It also supports tools like Single Sign- On (SSO), which allows access to several apps with one login. Extra security via OTP, cellphone prompt, etc. Multi-factor authentication (MFA). Every user gets access based on their position.

Ques6) What is Azure Blob Storage, and when would you use it ?
Answer- Azure Blob Storage is a cloud-based storage solution from Microsoft Azure that can store large amount of unstructured data, such as images, videos, documents, logs, backups, etc. The full form of “Blob” is Binary Large Object, and we use it when we need scalable, secure, and highly available storage — especially when data needs to be accessed or shared via the internet. 

Main use cases: To store images, documents, or videos of a website or mobile app To securely keep application logs or backup data To access data globally. This service from the cloud is useful when traditional on-premise storage is expensive or less reliable. It also easily integrates with other Azure services.

Ques7) What are the different types of cloud services offered by Azure ?
Answer- Azure mainly provides three types of cloud services: IaaS, PaaS, and SaaS.

 IaaS (Infrastructure as a Service): In this, Azure provides you basic infrastructure like virtual machines, storage, networking. You have to install OS, run applications, and manage configurations. Example: Azure Virtual Machines, Azure Load Balancer Use case: When you want full control over your server and software environment.

PaaS (Platform as a Service): In this, Azure gives you a ready-to-use platform where you can develop, test, and deploy your applications without managing the underlying infrastructure. Example: Azure App Services, Azure SQL Database Use case: When you want to focus only on application development, without worrying about infrastructure.

SaaS (Software as a Service): In this Azure provides fully functional software applications that can be used via the internet. Users only have to use the software; Azure has complete control of the backend. Example: Microsoft 365, Outlook, OneDrive Use case: When you need software in ready-to-use form without installation or maintenance.

Ques8) What are Azure Availability Zones?
Answer- Azure Availability Zones are an important feature of Microsoft Azure, which provides high availability and fault tolerance to your application.

Simply put, within an Azure Region (such as Central India) there are data centers built in 2 or 3 different geographic locations, which are called Availability Zones. Each zone has its own power supply, network and cooling system, so that if one zone fails, the rest of the zone is not affected.

Ques9) What is Azure DevOps and how is it used in CI/CD pipelines?
Answer- Azure DevOps is a Microsoft tool that makes software development easy and fast. Through this, teams can manage planning, coding, testing and deployment all from one place.

CI/CD means Continuous Integration and Continuous Deployment/Delivery.

CI (Continuous Integration): Whenever a developer writes new code, it is automatically tested so that there are no bugs or errors.

CD (Continuous Deployment): When the code passes testing, it is automatically deployed on the server—no manual process is required.

In Azure DevOps, you get tools to manage all these like:

  • Azure Repos (for storing code)
  • Azure Pipelines (for CI/CD)
  • Azure Boards (for task tracking)
  • Azure Test Plans (for testing)

So, Azure DevOps automates the entire process from development to production, which leads to faster delivery, better quality and improved teamwork.

Ques10) What is Azure Load Balancer ?
Answer- Azure Load Balancer is a networking service that distributes your application’s traffic evenly between multiple servers. It distributes the incoming traffic to different virtual machines or service instances so that no single server is overloaded and high availability is maintained.

It is of two types:

  • Public Load Balancer – which manages the traffic coming from the Internet.
  • Internal Load Balancer – which distributes traffic within the virtual network.

It also checks which server is working correctly with the help of health probes and routes traffic based on that.

Ques11) How is Azure Monitor different from Azure Application Insights?
Answer- Though they are both Azure’s monitoring tools, Azure Monitor and Application Insights have very distinct emphasis.

Comprising virtual machines, networks, databases, storage, etc., Azure Monitor is a complete monitoring solution tracking the performance and health of the whole Azure infrastructure. This covers dashboards, logs, measurements, and alarms.

Though it is mostly used to track application performance, error tracking, and user behavior, Azure Monitor includes Application Insights. It provides code-level information so that developers may rapidly identify application faults.

Ques12) What is Azure Virtual Network (VNet) and how does it work?
Answer- Azure Virtual Network (VNet) functions as your own, cloud-based private network. VNet lets you build a safe and separated network inside Microsoft Azure, just as your local network in an office (with computers, servers, routers, etc.) enables. Like with a conventional network, you can specify your own IP address ranges, subnets, and route tables.

Azure virtual network

It helps Azure resources—Virtual Machines (VMs), databases, and app services—talk securely among themselves. Using a VPN or Azure Express Route will let you link your VNet to your on-site network, therefore generating a hybrid cloud configuration. VNet lets network security groups (NSG) manage traffic entering and leaving your resources.

Ques13) What are Resource Groups in Azure? Why are they important?
Answer- A Resource Group is a container in Azure that holds related resources like VMs, databases, and storage—grouped by project or purpose.

Why it’s important:

  • Easy management of resources as one unit
  • Access control with RBAC at the group level
  • Cost tracking per group
  • Organized structure for projects or environments
  • Quick cleanup—delete all resources by deleting the group

It helps in managing, securing, and organizing Azure resources effectively.

Ques14) What is Azure Key Vault and why is it important?
Answer- Azure Key Vault is a cloud service for safely storing and controlling passwords, keys, certificates, and secrets used by services and applications.

Why it’s important:

  • Secure storage of sensitive information
  • Centralized key management
  • Access control using Azure Active Directory
  • Supports encryption and protects data
  • Helps meet compliance and security standards

Ques15) How can you secure data in Azure at rest and in transit ?
Answer- Data at Rest (Stored Data):

  • Encryption using Azure Storage Service Encryption (SSE)
  • Use Azure Disk Encryption for virtual machines
  • Store secrets in Azure Key Vault
  • Enable Transparent Data Encryption (TDE) for databases

Data in Transit (Moving Data):

  • Use HTTPS/TLS encryption for secure communication
  • Set up VPN or ExpressRoute for private connections
  • Enable Azure Firewall and NSGs for traffic control
