Numerous companies are looking for professionals certified in Microsoft Azure, especially after Gartner mentioned it as the second-highest profession in demand today. In this blog on Microsoft Azure interview questions and answers for freshers and experienced, we have combined a few of the most commonly asked questions in job interviews for different job profiles.
Here are some Interview Questions and Answers:
1. What is Azure Cloud Service?
Cloud service can convey multiple web applications in Azure, characterizing a number of parts to disseminate handling and permit adaptable scaling of your application. A cloud service comprises a minimum of one web part, as well as specialist parts, each with its own particular application documents and design. The fundamental favorable position of cloud service is the capacity to help more complex multilevel structures.
2. Microsoft Azure’s unique features and their benefits?
- Strong Support in Analytics
- Enhance Existing IT Support
- Unique storage system
- Enhanced scalability
- Enhanced flexibility
3. Why Do Business Owners Choose Microsoft Azure? or Why Azure is so popular?
Here are some of the major reasons to choose Azure for your enterprise:
- Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) capabilities
- Security Offerings
- Scalability and Ductility
- Unmatched Hybrid Capabilities
- Integrated Environment with Other Microsoft Tools
- Analytics and Intelligence capabilities
- Easy learning
- Cost-Efficient Platform
- Flexibility and Scalability
4. What type of web application can be deployed with Azure?
Microsoft released SDKs for both Java and Ruby to allow applications written in those languages to place calls to the Azure Service Platform API to the AppFabric Service.
5. Explain the Role in terms of Microsoft Azure.
Roles are nothing, but the servers are layman’s terms. Servers are managed, load-balanced, platform as a Service virtual machines that work together to achieve a common goal.
These roles are divided into three parts
- Web Role: It is used to deploy a website, using the languages supported by the IIS platform (like PHP, .NET, etc.). It was configured and customized to run web applications.
- Worker Role: It helps the web role to execute background processes, unlike the web Role, which is used to deploy the website.
- VM Role: It can be used by a user to schedule tasks and other windows services. We can use the VM role to customize the machine on which the web and worker role is running.
6. Can you tell me something about Azure Cloud Service?
- Azure Cloud Service is a classic example of a platform as a service (PaaS). This was designed to support those applications which demand high scalability, reliability, and availability all within the constraints of reduced cost of operations. These are hosted on virtual VMs and Azure provides more control over them by letting the developers install the necessary software and enabling them to control them remotely.
- Azure cloud services are used for deploying multi-tier web-based applications in Azure by means of creating an instance of cloud service. It is also possible to define multiple roles such as web roles, worker roles, etc for the purpose of distributed processing. Azure cloud services help in the easier and more flexible scalability of the application.
- Each role of the cloud service has its own purpose and thereby its own configuration and application files.
7. Define role instance in Azure.
A role instance is nothing but a virtual machine where the application code runs with the help of running role configurations. There can also be multiple instances of a role as per the definition in the cloud service configuration files.
8. How many cloud service roles are provided by Azure?
Cloud service roles comprise a set of application and configuration files. There are 2 kinds of roles provided by Azure:
- Web role: This provides a dedicated web server belonging to IIS (Internet Information Services) that is used for automatic deployment and hosting of front-end websites.
- Worker role: These roles help the applications hosted within them to run asynchronously for longer durations and are independent of the user interactions and generally do not use IIS. They are also ideal for performing background processes. The applications are run in a standalone manner.
9. Why is Azure Diagnostics API needed?
- Azure Diagnostics API helps us collect diagnostic data such as performance monitoring, system event logs, etc from the applications that are running on Azure.
- For the verbose monitoring of the data, Azure Diagnostics has to be enabled for the cloud service roles.
- The diagnostics data can be used for building visual chart representations for better monitoring and also for creating performance metric alerts.
10. Define Azure Service Level Agreement (SLA)?
- The Azure SLA is a contract that ensures or guarantees that when two or more role instances of a role are deployed on Azure, access to that cloud service is guaranteed for at least 99.95% of the time.
- It also states that if the role instance process is not in the running state, then the detection of such processes and corrective action for the same will be taken 99.9% percent of the time.
- If the mentioned guarantees are not satisfied at any point in time, then Azure credits a percentage of monthly fees to us depending on the pricing model of the respective Azure services.
11. What is Azure Resource Manager?
Azure Resource Manager is a service provided by Azure to provide management and application deployment in Azure.
The resource manager provides the management layer that helps the developer to create, modify or delete the resources in the Azure subscription account. This feature comes in handy when we have requirements like managing access controls, and locks, ensuring the security of the resources post-deployment, and organization of those resources.
12. What is NSG?
NSG stands for Network Security Group that has a list of ACL (Access Control List) rules that either allows/denies network traffic to subnets or NICs (Network Interface Card) connected to a subnet or both. When NSG is linked with a subnet, then the ACL rules are applied to all the Virtual Machines in that subnet.
Restrictions of traffic to individual NICs can be done by associating NSG directly to that NIC.
13. What is Azure Data Factory?
Azure Data Factory is a serverless and cloud-based data integration service and platform used for the creation of ETL and ELT pipelines. It helps in the creation of data-driven workflows for the planning and execution of data movements and data transformation at scale.
14. What is Azure Databricks?
Azure Databricks is a Data Analytics platform that offers two environments for the development of data-intensive applications:
- Azure Databricks SQL Analytics
- Azure Databricks Workspace
Azure Databricks’ integration with the security, compute, analytics, storage, and AI services that are natively provided by cloud providers facilitates the unification of data and AI workloads.
15. What is Azure Data Lake?
Azure Data Lake is a cloud platform that supports Big Data Analytics through its unlimited storage for structured, semi-structured, or unstructured data of all types and sizes.
16. What are Azure resources?
Any entity managed by Azure can be referred to as an Azure resource. The following are some examples of Azure resources: Storage accounts, virtual networks, virtual machines, etc.
17. What are the roles implemented in Windows Azure?
- Web Role
- Worker Role
- Virtual Machine Role
18. How is the price of the Azure subscription placed?
Answer: The prices vary in accordance with the product type. The various pricing models are;
- The free model where our customers can avail of the system is exempted from the market fee.
- The BYOL scheme where the Azure is fetched the Azure with a fee that is not encircled around the limits of the market price.
- The trial of the free software where the client gets the full version with an advanced feature for a limited period of time. With the expiration of the introductory period, you will be charged standard rates.
- Usage-Based Fee that is billed in accordance with the service that you have taken. Like if you are subscribed for the virtual image then hourly fees may be charged.
- Monthly bills are activated if you sign a particular plan. The fee is not allocated for cancellation or mid-month unused service.
19. 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.
20. 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.
