Beginner Azure Interview Questions

1. Why Did You Choose a Career in Cloud Computing?

These types of Azure interview questions require a thoughtful, honest response. By thinking through your answer ahead of time, you’ll be ready to say something your interviewer will approve of. Show that you care about the field and that you have a passion for cloud computing and the problems it can solve.

2. Why Did You Choose Microsoft Azure and Not Aws?

Your response to this question is based on your own background and experience. Maybe you come from a developer background, so Azure appealed to you. Maybe your first cloud computing role just happened to be with Azure. As with the question above, the key here is to be ready to give an intelligent answer to the question.

3. How Does Microsoft Azure Compare to Aws?

This might be a matter of opinion for you, so answer as you see fit. In general, people say Azure is a better choice because it’s a Microsoft product, making it easier for organizations already using Windows Server, SQL Server, and Exchange to move to the cloud. In addition, because of Microsoft’s deep knowledge of developer tools, Azure offers multiple app deployment options for developers, which makes it stand out against AWS.

4. How Did You Learn Azure?

Did you learn Azure through a certification? Through on-the-job experience? A little of each? However you learned it, make sure to demonstrate to the interviewer that you have practical experience (if you’re new to the field) and that you are continuing to learn.

5. Tell Me About a Problem You Solved at Your Prior Job.

This is something to spend some time on when you’re preparing responses to possible Azure interview questions. As a cloud architect, you need to show that you are a good listener and problem solver, as well as a good communicator. Yes, you need to know the technology, but cloud computing does not usually involve sitting isolated in a cubicle. You’ll have stakeholders to listen to, problems to solve, and options to present. When you answer questions like these, try to convey that you are a team player and a good communicator, in addition to being a really good Azure architect.

6. What is the difference between SaaS, PaaS, and IaaS?

This is one of the most common Azure interview questions. Cloud Computing has three types of service models, that are IaaS, PaaS, and SaaS

Infrastructure as a Service(IaaS)

Platform as a Service(PaaS)

Software as a Service(SaaS)

It enables developers to build and work with applications without having to worry about the infrastructure or management of the hosting environment.

It involves applications being consumed and used by organizations. Usually, organizations pay for their use of the application

Example -  Azure Virtual Machine, Azure VNET

Example -  Azure SQL, Azure Storage

Example -  Office 365, Salesforce

  • It automatically deploys and hosts applications through the users IIS

Worker Roles

  • It runs applications and other tasks that don't require IIS. It performs supporting background tasks along with web roles
  • It doesn’t use IIS and runs user applications standalone 

22. What is Azure Service Fabric?

Service Fabric provides a platform that makes the process of developing microservices and managing the application lifecycle easier.

  • It produces applications with faster time to market

23. How can Azure handle this situation?

A client wants the front end of his/ her application to be hosted on Azure, but wants the database to be hosted on-premises.

onpremises

Solution - The ideal solution in this scenario is to use Azure VNET based “Point to Site”. It’s best suited for scenarios where there are only a limited number of resources that need to be connected  

24. What is the Azure Traffic Manager?

Azure Traffic Manager is a traffic load balancer that enables users to provide high availability and responsiveness by distributing traffic in an optimal manner across global Azure regions.

  • It provides multiple automatic failover options 
  • It helps reduce application downtime
  • It enables the distribution of user traffic across multiple locations
  • It enables users to know where customers are connecting from

25. How can Azure handle this situation?

You need to isolate network traffic among VMs in a subnet, which is part of a Virtual Network with little downtime and impact on users?

virtual-network

Solution - This would ensure that the virtual machines are kept isolated without the need for additional security, like a Network Security Group.

26. With respect to Azure, what is public, private, and hybrid cloud?

Public Cloud - Every component that the user is using in his/ her application are running only on Azure

public-cloud

Private Cloud - Azure services are being run within an on-premises data center or on-premises data centers are used by the user to host systems or applications 

private-cloud

Hybrid Cloud - Combines features of both Public and Private cloud. Some of the user’s components are being run on Azure and others within an on-premises datacenter

hybrid-cloud

27. What kind of storage is best suited to handle unstructured data?

Questions on Blob Storage can be seen in the list of Azure Interview Questions.

Blob Storage provides storage capacity for data. It places data into different tiers based on how often they’re accessed.
