Top Azure Interview Questions and Answers Just For You
Basic Questions
What is Microsoft Azure?
- Answer: Microsoft Azure is a cloud computing platform and service created by Microsoft. It offers a wide range of cloud services, including those for compute, analytics, storage, and networking. Users can choose and configure these services to develop and scale new applications or run existing applications in the public cloud.
What are the key benefits of using Azure?
- Answer: Key benefits include scalability, flexibility, cost management, global reach, and robust security. Azure allows businesses to scale resources up or down based on demand, supports multiple programming languages and frameworks, offers various cost management tools, operates data centers worldwide, and adheres to stringent security protocols.
What are Azure Resource Groups?
- Answer: Azure Resource Groups are containers that hold related resources for an Azure solution. They help manage and organize resources, enabling you to deploy, update, and delete all the resources in a resource group as a single unit.
Intermediate Questions
What is Azure Virtual Network (VNet)?
- Answer: Azure Virtual Network (VNet) is a fundamental building block for your private network in Azure. It allows Azure resources to securely communicate with each other, the internet, and on-premises networks. VNets provide isolation, segmentation, and control over network traffic.
Explain the difference between Azure SQL Database and SQL Server on Azure VMs.
- Answer: Azure SQL Database is a fully managed relational database service, offering high availability, scalability, and automated backups. SQL Server on Azure VMs provides more control over the database environment and is ideal for applications requiring custom configurations and high customization, but it requires manual management of backups, patching, and other administrative tasks.
What is Azure Blob Storage?
- Answer: Azure Blob Storage is a service for storing large amounts of unstructured data, such as text or binary data. Blobs can be accessed via HTTP or HTTPS and are ideal for storing data for backup, disaster recovery, and archiving, as well as serving images or documents directly to a browser.
Advanced Questions
What is Azure Kubernetes Service (AKS)?
- Answer: Azure Kubernetes Service (AKS) is a managed container orchestration service based on the open-source Kubernetes system. AKS simplifies deploying, managing, and scaling containerized applications using Kubernetes, offering integrated CI/CD capabilities and enterprise-grade security and governance.
How does Azure ensure security and compliance?
- Answer: Azure ensures security and compliance through a multi-layered security approach, including physical security, identity management, network security, and encryption. Services like Azure Security Center provide unified security management, and Azure adheres to various compliance certifications like ISO 27001, HIPAA, and GDPR.
What is Azure DevOps, and what are its components?
- Answer: Azure DevOps is a set of development tools provided by Microsoft to support the entire application lifecycle. Its components include Azure Repos for source control, Azure Pipelines for CI/CD, Azure Boards for work tracking, Azure Artifacts for package management, and Azure Test Plans for testing and capturing feedback.
Explain the concept of Azure Availability Zones.
- Answer: Azure Availability Zones are physically separate locations within an Azure region. Each zone consists of one or more data centers equipped with independent power, cooling, and networking. Availability Zones offer high availability and fault tolerance by ensuring that services remain available even if one zone goes down.
Scenario-Based Questions
How would you migrate an on-premises application to Azure?
- Answer: To migrate an on-premises application to Azure, you would typically follow these steps: assess the application and its dependencies, choose the appropriate migration strategy (lift-and-shift, replatforming, or refactoring), use Azure Migrate to discover and assess on-premises resources, create the necessary Azure resources (e.g., VMs, databases), migrate the data, and finally, test and optimize the application in the Azure environment.
How do you implement disaster recovery in Azure?
- Answer: Disaster recovery in Azure can be implemented using Azure Site Recovery, which replicates workloads running on physical and virtual machines (VMs) from a primary site to a secondary location. In the event of a disaster, you can failover to the secondary location and access your applications and data with minimal downtime.
