Most Asked Azure Interview Questions & Answers – Be Ready!
Introduction
1️⃣ What is Microsoft Azure?
✅ Answer:
Azure is Microsoft’s cloud computing platform that provides infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) solutions. It offers services such as virtual machines, databases, artificial intelligence, networking, and security. Businesses use Azure to build, deploy, and scale applications globally with high availability and security.
💡 Key Benefits: Scalability, pay-as-you-go pricing, global reach, and integration with Microsoft products.
2️⃣ What are Azure Availability Zones?
✅ Answer:
Azure Availability Zones are physically separate data centers within an Azure region that ensure high availability and fault tolerance. They help protect applications and data from data center failures by distributing workloads across multiple zones.
💡 Example: If one data center goes down due to an outage, services hosted in another zone remain unaffected, ensuring business continuity.
3️⃣ What is the difference between Azure Virtual Machines (VMs) and Azure App Services?
✅ Answer:
• Azure Virtual Machines (VMs) provide full control over the operating system, applications, and configurations. They are ideal for running traditional applications that require specific configurations.
• Azure App Services is a fully managed Platform-as-a-Service (PaaS) offering that allows developers to deploy web applications without worrying about infrastructure management.
💡 When to Use: Choose VMs for customized environments and App Services for quick deployments with automatic scaling.
4️⃣ What is Azure Kubernetes Service (AKS)?
✅ Answer:
Azure Kubernetes Service (AKS) is a managed Kubernetes platform that simplifies container orchestration. It allows organizations to deploy, scale, and manage containerized applications without managing the underlying infrastructure.
💡 Use Case: AKS is ideal for microservices architecture, where applications are broken into smaller, independent services that run in containers.
5️⃣ What is the difference between Azure Blob Storage and Azure File Storage?
✅ Answer:
• Azure Blob Storage is optimized for storing unstructured data such as images, videos, and logs.
• Azure File Storage provides SMB-based file shares, allowing applications to access data across multiple virtual machines.
💡 Key Differences: Blob storage is great for large-scale data storage, while File Storage is ideal for shared file systems.
6️⃣ What is an Azure Virtual Network (VNet)?
✅ Answer:
Azure Virtual Network (VNet) is a private network within Azure that enables secure communication between Azure resources such as virtual machines, databases, and services.
💡 Use Case: VNets allow businesses to create isolated cloud environments, ensuring security and compliance.
7️⃣ What is the difference between Azure Active Directory (Azure AD) and Windows Active Directory?
✅ Answer:
• Azure AD is a cloud-based identity and access management (IAM) service, used for single sign-on (SSO), multi-factor authentication, and security for cloud applications.
• Windows AD is an on-premises directory service that manages users, groups, and security policies within a local network.
💡 Key Difference: Azure AD is designed for cloud-based applications, while Windows AD is used for traditional on-premises infrastructure.
8️⃣ How does Azure Key Vault help in securing application secrets?
✅ Answer:
Azure Key Vault is a cloud-based security service that stores and manages sensitive information, such as API keys, passwords, and certificates. It provides encryption and access control to protect secrets from unauthorized access.
💡 Security Advantage: By using Azure Key Vault, businesses can prevent security breaches caused by hardcoded credentials in codebases.
9️⃣ What are Azure Logic Apps, and why are they used?
✅ Answer:
Azure Logic Apps provide a low-code/no-code way to automate workflows, integrate applications, and streamline business processes.
💡 Example: Logic Apps can automatically trigger an email notification when a file is uploaded to Azure Blob Storage.
1️⃣0️⃣ What is Azure DevOps, and how does it help in software development?
✅ Answer:
Azure DevOps is a cloud-based platform that provides tools for continuous integration (CI) and continuous deployment (CD), source code management, and agile project tracking.
💡 Key Features:
✔ Azure Repos – Git-based version control
✔ Azure Pipelines – Automates build and release processes
✔ Azure Boards – Agile project management
