Understanding Microsoft Azure

Azure is Microsoft's robust cloud platform, empowering the building, deployment, and management of applications and services for a global audience. It seamlessly integrates with existing networks or handles all your computing and networking needs, providing secure and reliable access to your cloud data. Azure offers a comprehensive suite of services, including Virtual Machines, SQL Databases, Azure Active Directory, Application Services, and robust storage solutions – everything you need to build and deploy globally accessible applications.

The following questions are categorized by expertise level, allowing you to focus on areas relevant to your experience. However, a complete review is recommended for optimal preparation.

Microsoft Azure Interview Questions

Fundamental Concepts:

1. Cloud Deployment Models: Describe the three main cloud deployment models (Public, Private, Hybrid) and their key differences.

   Public Cloud: Shared infrastructure owned and managed by a provider. Private Cloud: Dedicated infrastructure owned and managed by a single organization. Hybrid Cloud: A combination of public and private cloud environments.

2. Azure Role Instance: What is an Azure role instance, and how many instances of a role can exist?

   A role instance is a virtual machine running application code based on defined role configurations. Multiple instances can exist, as specified in the cloud service configuration files.

3. Network Security Groups (NSGs): Explain the purpose of NSGs and how they control network traffic.

   NSGs contain Access Control List (ACL) rules to allow or deny network traffic to subnets and/or Network Interface Cards (NICs). They can be associated with subnets or individual NICs for granular control.

4. Azure Diagnostics API: Why is the Azure Diagnostics API important, and what type of data does it collect?

   The Azure Diagnostics API collects diagnostic data (performance metrics, event logs) from Azure applications, enabling detailed monitoring, charting, and alert creation.

5. Azure Resource Manager and Traditional Deployments: Can you use Azure Resource Manager to create VMs in virtual networks created through traditional deployments? (True/False)

   False.

6. Azure Redis Cache: Explain the purpose and benefits of using Azure Redis Cache.

   Azure Redis Cache is a managed in-memory data store that improves application performance by caching frequently accessed data.

Intermediate to Advanced Concepts:

7. Deployment Environments (Staging & Production): Describe the purpose of staging and production environments in Azure.

   Staging: Used for testing and validating application changes before deployment to production. Production: The live environment where the application is accessible to users.

8. Drive Failure in Azure: What are the critical steps to take when a drive failure occurs in an Azure environment?

   Unmount the failed drive, replace it, remount, and format the replacement drive. Prioritize ensuring continued Azure storage functionality.

9. Azure Storage Keys: What are Azure storage keys, and how many are typically provided?

   Storage keys authenticate access to Azure storage services. Two keys (primary and secondary) are provided for redundancy.

10. Azure ID Authentication Failure: What happens when the maximum number of failed authentication attempts is reached for an Azure ID?

    The account is locked, with the locking mechanism depending on the password and the IP address of the login request.

Data Storage and Services:

11. Azure Table Storage vs. Azure SQL Database: Compare and contrast Azure Table Storage and Azure SQL Database. (See table in original text for comparison)

12. Azure Storage Queue vs. Azure Service Bus Queue: Compare and contrast Azure Storage Queue and Azure Service Bus Queue. (See table in original text for comparison)

13. IaaS, PaaS, and SaaS: Define and differentiate IaaS, PaaS, and SaaS.

    IaaS (Infrastructure as a Service): Provides virtualized computing resources (servers, storage, networking). PaaS (Platform as a Service): Provides a platform for developing and deploying applications. SaaS (Software as a Service): Provides ready-to-use software applications.

Advanced Concepts and Best Practices:

14. Azure Scheduler: What is the Azure Scheduler used for?

    The Azure Scheduler automates tasks by scheduling jobs to run at specific times or intervals.

15. Preventing Application Overload: What Azure feature can help prevent application overload issues in the absence of manual intervention?

    Azure Virtual Machine Scale Sets automatically scale the number of VMs based on application demand.

16. Azure Blob Storage: Explain Azure Blob Storage, its different blob types, and its use cases.

    Azure Blob Storage is object storage for unstructured data. Types include block blobs, append blobs, and page blobs. Use cases include storing images, videos, and documents.

17. Benefits of Azure Scaling: What are the advantages of using Azure's scaling capabilities?

    Improved application performance, cost optimization, and the ability to handle fluctuating demand.

18. Azure Fabric: Explain the role and function of Azure Fabric.

    Azure Fabric is the underlying infrastructure that manages and orchestrates Azure services.

19. Azure Backup: Describe Azure Backup, its benefits, and what it can back up.

    Azure Backup is a cloud-based backup solution for various Azure services and on-premises data. Benefits include cost-effectiveness, scalability, and data protection.

20. Azure Table Concepts: Explain the key concepts of tables in Azure Storage.

    Azure Tables store structured NoSQL data in entities with key-value pairs.

Azure Web Services and Queues:

21. Azure Web Service Roles: What are the two main types of Azure web service roles, and what are their differences?

    Web Roles: Host web applications using IIS. Worker Roles: Execute background tasks without IIS.

22. Azure Queue Storage Advantages: What are the key advantages of using Azure Queue Storage?

    Scalability, durability, cost-effectiveness, and support for various programming languages.

Hybrid Cloud and Conclusion:

23. Hybrid Cloud Integration Benefits: How does hybrid cloud integration benefit Azure users?

    Improved productivity, faster application development, and the ability to deploy applications across on-premises and cloud environments.
