Azure Interview Questions and Answers for Beginners

1. Describe Cloud Computing.

Cloud computing uses internet-based computers to store, manage, and process data. Rather than managing its own servers, third-party companies such as Microsoft and AWS provide and manage infrastructure for a fee based on usage time. It improves speed, flexibility, and scalability while providing high fault tolerance and system availability dependent on application needs.

2. Describe the Azure Cloud Service concept.

Microsoft's Azure Cloud Service is a platform as a service (PaaS) offering aimed at highly scalable, dependable, and available applications at a low operational cost. It makes use of virtual VMs, which allow developers to remotely install and control software. This service is perfect for deploying multi-tier web applications, as it allows for the creation of instances and the definition of roles such as web or worker roles for distributed processing. Each role in the cloud service has its own set of configuration and application files, allowing for simple and flexible scalability.

3. What are the various cloud deployment models available?

There are three cloud deployment models available:

1. Public Cloud: The cloud provider's public cloud, with shared server resources across several applications.
2. Private Cloud: Exclusively owned by us or offered by the cloud provider. Applications can be hosted on-premises or on a dedicated server provided by the cloud provider.
3. Hybrid Cloud: A hybrid of both public and private clouds. It could entail deploying on-premise servers for sensitive data processing & leveraging public cloud features for hosting public-facing applications.

4. Explain an Azure role instance.

A role instance is nothing more than a virtual machine on which application code executes with the assistance of running role configurations. A role can also have numerous instances, as defined in the cloud service configuration files.

5. How many different types of cloud service roles does Azure offer?

Cloud service roles are made up of a collection of application and configuration files. Azure offers two different types of roles:

1. Web role: This role provides a dedicated IIS (Internet Information Services) web server for the automatic deployment and hosting of front-end websites.
2. Worker roles: These roles allow the programs hosted within them to run asynchronously for longer periods of time, are independent of user interactions, and do not typically use IIS.

6. What is the purpose of the Azure Diagnostics API?

The Azure Diagnostics API collects diagnostic data from Azure apps, such as system event logs and performance monitoring. For the cloud service roles, Azure Diagnostics must be enabled. The acquired data can then be used to generate visual chart representations for enhanced monitoring and performance metric warnings.

7. Explain the Service Level Agreement (SLA) for Azure.

The SLA guarantees that access to your cloud service will be maintained at least 99.95 percent of the time when you send two or more role instances for each role. Additionally, when a role instance's procedure isn't running, 99.9% of the time, identification and re-correction actions will be begun.

8. What is Azure Resource Manager and how does it simplify resource management?

Azure Resource Manager, a service provided by Azure, manages and deploys applications in Azure. The management layer aids in the creation, modification, and deletion of resources in the Azure subscription account. It is useful for managing access controls, locks, and resource security.

9. What does Azure's NSG stand for?

Network Security Groups, or NSGs, are groups with access control lists, or ACLs, that contain a list of rules that either permit or prohibit network communication to subnets, NICs (Network Interface Cards) connected to subnets, or both. All Virtual Machines within a subnet that is linked to NSG are subject to the ACL rules.

10. Is it accurate to say that in a virtual network established by traditional deployment, virtual machines can be built using Azure Resource Manager?

False. This is not supported by Azure.

11. Explain Azure Redis Cache.

Azure Redis Cache is an in-memory Redis cache technology designed to enhance performance for web applications. Using the Azure cloud, Azure Redis Cache offers strong and safe caching technologies.

12. Describe the scale sets of Azure virtual machines.

• Sets of identical Virtual Machines (VMs) can be deployed and managed using these Azure compute resources.
• These scale sets have the same configuration and are made to allow applications to autoscale without requiring virtual machines to be pre-specified.
• They facilitate the easier development of large-scale applications aimed at containerized workloads and big data.

13. What do you know about Azure's "Availability Set"?

All that an availability set is is a logical collection of virtual machines, or VMs, that tells Azure Cloud how an application was designed to be available and redundant. Azure gives you the freedom to set up as many as 20 update domains and three fault domains for each availability set. Azure gives each virtual machine in the availability set one of two types of domains:

1. Update Domain
2. Fault Domain

14. What choices are there for Azure's deployment environments?

Two deployment environments exist:

1. Staging environment: This is where modifications to an application are tested before going live.
2. Production environment: Target users can access applications in this environment using a DNS-friendly URL after they become live.

15. What actions need to be performed in the event that an Azure drive fails?

The actions listed below must be taken in the event of a drive failure:

• To guarantee that Azure Storage runs flawlessly, make sure the drive is not mounted.
• Change out the drive remount and format it.

16. Are you able to create Azure applications that can deal with connection failures?

Certainly, the Transient Fault Handling Block makes it feasible. Periodic application-to-database connection failures with more load balancers, slower calls, and timeouts in multi-tenant services, or the frequent user hit resulting in purposeful connection denial to support other tenants in the architecture can all be causes of transient failures in the cloud.

17. Define an Azure storage key.

Depending on the needs of the project, an Azure storage key is used to authenticate access to data stored on Azure storage services. Two categories of storage keys are used in authentication:

1. Primary access key
2. Secondary access key, to prevent website or application downtime

18. What is cspack and how does Azure use it?

A command-line utility called CSPack creates the service package file and gets an application ready for Compute Emulator or Azure deployment. The cloud service configuration file, or .cscfg file, created with CSPack, is included in every project including cloud services. It keeps:

• The number of role instances in each deployment for each role
• Thumbprints on the certificates
• Configurations that are defined by the user

19. Which Azure option works best for code execution without a server?

Serverless code execution is made possible by Azure Functions, which makes intricate orchestration and resolution easier. They eliminate the need for hard-coded integrations by facilitating smooth connections with other services through their stateless and transient design. With this method, work is sped up and developers can concentrate on writing business logic code. Furthermore, Azure Functions provide performance analysis and monitoring capabilities via Azure Application Insights, which help locate bottlenecks and sites of failure in the application components.

20. Which Azure function is suggested for a shared file-sharing setup amongst several virtual machines?

The Azure File System serves as a single repository for exchanging data between virtual machines that are set up with protocols like SMB, FTP, NFS, and so on.

Azure Scale Sets	Azure Availability Sets
They are a collection of virtual machines with the same configuration dispersed among several fault domains.	They are the collection of individually configured virtual machines dispersed among different fault domains.
These by default update domains and have five fault domains.	These come with three fault domains and five update domains by default.
These are used when unpredictable workloads necessitate the auto-scaling capability.	When workload requirements are predictable, these are used.
In this case, the virtual machines are set up and made using the same picture in the same way.	Here, various images and parameters are used to construct the virtual machines (VMs).
Depending on demand or the predetermined timetable, the number of virtual machines (VMs) can be changed.	An availability set can only have VMs added to it at the time the set is created.
In this case, the VM scale sets may be split up over several data centers or contained in a single data center.	Here, a data center's virtual machines are distributed automatically.

23. What occurs when the number of unsuccessful tries during Azure ID authentication is reached?

Depending on the protocol that analyses the password that was input and the IP address that the login request was made from the Azure account will be locked in this case.

24. Is it possible to get the Azure Internal Load Balancer's public DNS or IP address?

No. Only private IP addresses are supported by Azure Internal Load Balancer.

25. Describe the concept behind Azure Blob Storage.

The cloud's solution for object storage is Azure Blob (binary huge object) storage. It can be used to provide documents, media, or text straight to the browser and can store enormous amounts of unstructured data in binary or text format. You can access the data from any location. The blobs are associated with user accounts and arranged into containers. There are three parts to this service:

1. Storage account
2. Container
3. Blob

26. Describe Azure Scheduler and explain how to use it.

With Azure Scheduler, we can call specific background trigger events or actions on demand, such as displaying a message on the queue or contacting HTTP/S endpoints. The jobs that are present in the cloud call services both inside and outside of Azure can be scheduled to start at a future date or to run on-demand according to a regular schedule by using this Azure Schedule.

27. Can a Windows computer running on a separate port be mapped to an Azure load balancer?

In Azure, you may achieve this by creating a different load balancer role.

28. When there is no manual help available, which Azure feature can be used to manage heavy application loads?

By using Azure VM Scale Sets to configure conditions for creating new VMs when the application load grows, you may address this issue. Developer-managed scale settings that allow load-balanced virtual machine groups to be created. High availability is ensured by automatic scaling based on application demand or a preset timetable. Large virtual machines (VMs) may be more easily managed, updated, and configured centrally, which helps developers create applications with high data, workload, and compute requirements. When utilizing custom images, the maximum number of virtual machines (VMs) that Azure scale sets can support is 1,000.

29. What other kinds of storage services does Azure offer besides blob storage?

In addition to Blob storage, table storage, queue storage, and file storage, Azure provides three more categories of storage services.

1. Azure table storage: This NoSQL-based key-value store enables the development of applications using semi-structured data.
2. Azure queue storage: By creating robust and adaptable applications, the message queue system can manage heavy workloads.
3. Azure file storage: SMB (server message block) protocol is used to provide file access and sharing. SMB 3.0 and HTTPS are used to safeguard the data.

30. Describe Azure's IaaS, PaaS, and SaaS offerings.

• IaaS: Infrastructure as a Service is shortened to IaaS. It provides a number of infrastructure-level functions, like OS and network connectivity. It operates on a pay-per-use basis. It serves as an application host. Examples of this kind of infrastructure are Azure VM and VNET.
• PaaS: Platform as a Service, or PaaS, is an abbreviation. Its main feature is the abstraction of the underlying infrastructure, which enables faster application development without the burden of hosting management. PaaS includes things like storage services, cloud services, Azure web apps, etc.
• SaaS: Software as a Service is referred to as SaaS. These apps are provided under a service delivery paradigm in which an organization only uses the applications. SaaS comes after advertising or subscription-based pricing. SaaS examples include Office 365, Gmail, SharePoint Online, and so forth.

31. What distinguishes Azure SQL service from Azure Table Storage?

The following lists the primary distinctions between Azure SQL Service and Azure Table Storage:

Table Storage Service	Azure SQL Table
This uses Azure's NoSQL storage model.	It is organized according to Azure's relational storage model.
This data is called an entity and is kept in key-value format.	Here, the data is kept in an SQL table in a combination of rows and columns.
For storage, the data schema is not required.	When a schema violation happens, an error is produced because the data schema is strictly followed for data storage.
It is not possible for tables to be related to one another.	Foreign keys are used to define relationships between tables.
Each entity's partition and row key combination are thought to be distinct.	A primary key or unique key can be used by the user to define uniqueness.
You can store diagnostics data or log information using this service.	Applications that rely on transactions frequently use this service.

32. How can connectivity be managed in Azure when the database must be on an on-premise server due to security concerns and the application front end is hosted there?

• For a limited number of resources, link an on-premise database to an Azure-hosted application by using the Azure VNET-based "Point to Site" service.
• Take "Site to Site" or "Express Routes" into consideration if you have a lot of resources.
• Although "Site to Site" VPN connections may result in network latency, "Express Routes" offer a dedicated leased line to circumvent this problem.
• Create an on-premise Windows Communication Foundation (WCF) service and host CRUD activities only for the on-premise database if the customer would rather not operate via VNET.
• For database access, use the "Service bus relay" option to facilitate communication between the WCF service and the Azure-hosted application.

33. What distinguishes Azure Service Bus Queue from Azure Storage Queue?

The following lists the primary distinctions between the Azure Storage Queue and the Azure Service Bus Queue:

Azure Storage Queue	Azure Service Bus Queue
First In First Out (FIFO) ordering is not guaranteed in this case.	Sessions ensure that the messages are delivered in FIFO order.
There is no support for sessions.	Here, messaging-level sessions are supported.
The "At Least Once Delivery" model is the only one that is accepted here.	This supports the message delivery modes of "At least once," "Atmost once," and "Exactly once."
Here, duplicates are not automatically detected.	This supports the automatic detection of duplicates.
Dead lettering is not supported.	Dead lettering is supported.
The message has a 64KB size.	The message has a 256 KB size.
Supports message delivery one-to-one.	Supports both one-to-one and one-to-many message delivery.
There is no support for the transaction.	Here, the transaction is supported.
Only batch receive is supported by this queue.	This allows for the sending and receiving of messages in batches.
Receiving messages behaves in a non-blocking manner.	Depending on the setup, the behavior may be blocking or non-blocking.

34. What are the various causes of a client application getting disconnected from the cache?

There are two potential reasons:

1. Causes on the client side: It's possible that the application was redeployed. It could have just been a scaling procedure by the application. There have been changes to the client-side networking layer. There could be momentary problems with the client or the network connecting the client and server. Another cause can be that the bandwidth threshold restrictions have been exceeded.
2. Causes on the server: It could happen if there is a failover from the primary to the secondary node in the Azure Redis Cache service itself. It's possible that maintenance or patches were applied to the server instance where the cache was installed.

28. What are some common security threats in Azure?

Here are Some common security threats in Azure :

• Data breaches: The unauthorized access to sensitive data stored in the cloud.
• Denial of Service (DoS) attacks: The attempts to overload a system and prevent access to resources.
• Malware and viruses: The malicious software can spread throughout a system and cause damage.
• Configuration errors: The mistakes in setting up Azure resources, such as exposing resources to the internet.

29. Discuss the concept of resource groups in Azure.

These are like folders for organizing your resources. Just like you put your books and clothes into different boxes, you can put your different resources in Azure, like virtual machines, databases, and websites, into different resource groups. This makes it easier to manage and keep track of all your resources.

30. How do you manage storage in Azure, and what are some standard storage solutions used in Azure?

Managing storage in Azure includes deciding how to store data, what types of storage to use, and how to access and manage that data.

Here are Some standard storage solutions used in Azure are:

1. Azure Blob Storage: Used for unstructured data like images, videos, and text files.
2. Azure Files: Used for file storage and sharing and is similar to a traditional file server.
3. Azure Queue Storage: The Messages that may be read and processed by numerous apps are stored in this area.
4. Azure Disk Storage: Used for virtual machine storage and offers high performance and low latency.

To manage this storage in Azure, we can use the Azure Portal, Azure CLI, or Azure Powershell to create and also configure storage accounts, manage access control, monitor performance and usage, and set up backup and disaster recovery.

31. Discuss the difference between Azure PaaS and IaaS.

PaaS	laaS
PaaS stands for Platform as a Service	IaaS stands for Infrastructure as a Service
PaaS provides a platform for developers to build and deploy applications without bothering about managing the underlying infrastructure.	IaaS provides a virtualized computing environment, which includes virtual machines, storage, and networking.
Azure takes care of the hardware, software, and networking components, so developers can focus on writing code and building applications.	In this, the customer is responsible for managing the operating system, applications, and data, while the cloud provider is responsible for the underlying infrastructure.

32. Define Azure Subscriptions.

It is a way to access Azure resources logically. It holds information about your resources, such as databases, virtual machines (VMs), and more. When we make an Azure resource, like a virtual machine, you set it apart from the subscription it is part of.

 Azure subscription denotes

• Entity for billing and the security boundary.
• A place where users can go.
• How much do Azure services cost each month?

33. Which is better, Google Cloud Platform Cloud AutoML or Microsoft Azure ML Studio?

When comparing the two, Azure ML Studio comes out on top due to its outstanding features, including classification, regression, anomaly detection, clustering, recommendation, and ranking. However, The GCP Cloud AutoML has built-in support for clustering, regression, and recommendation. Azure also has convenient drag-and-drop features that save time and effort.

34. Explain in detail the Azure Machine Learning Text Analysis API.

It is a collection of web services for analyzing text. Extracting relevant information and analyzing sentiment from the unstructured text are two of its primary functions. It gives out numbers between 0 and 1, which can be interpreted as positive or negative feelings.

35. Which Azure service manages Azure resources?

Here, Some of the Azure services that manage resources are

• Application Insights
• Azure Resource Manager
• Azure Portal
• Log Analytics

36. How does Azure CLI create a virtual machine (VM)?

• resource-group myResourceGroupName `
• name myVM --image win 2016 datacenter `
• admin-username AzureuserNAME `
• admin-password AzurePASSWORD

37. Why do we need the Azure Diagnostics API?

Here, We can collect diagnostic data from Azure applications such as performance monitoring, system event logs, and so on. And to monitor data verbosely for cloud service roles, Azure Diagnostics must be enabled. Diagnostics data is used to create visual chart representations for better monitoring and performance metric alerts.

38. Why does Azure Websites have a "Migration Assistant" tool?

Using Migration Assistant, we can check out your IIS configuration. It Assists in determining which server can be moved to the cloud. There are parts of it that still need to be migrated to Azure or need to be supported.

39. How can Azure deploy web applications?

The Applications that are deployable use either ASP.NET, PHP, or WCF.

40. What are Update Domains?

It is a logical collection of the underlying hardware that can be maintained or restarted simultaneously. And, the Azure platform automatically distributes the virtual machines we create within an availability set across these update domains.

41. What are Network Security Groups, and what do they do?

It is a group of Access Control List (ACL) rules that control whether network traffic can reach specific NICs (network interface cards), subnets, or both. NSGs can be linked to specific NICs connected to one or more subnets. The ACL restrictions apply to all VMs in a subnet with an NSG connection.

42. Do Azure availability and scale sets work together?

Yes. Here,The five fault domains and five update domains that make up a scale set constitute an implicit availability set. The Scale sets with more than 100 virtual machines (VMs) are distributed across several placement groups, representing several availability sets. 

43. What is Azure's CSPack?

CSPack is a command-line tool that makes the service package file and gets an app ready for deployment in Azure or Compute Emulator. Every project with a cloud service type has a configuration file .cscfg file, which was made with CSPack.

44. Why is Azure used to fix IP addresses?

The static IP address is used when a device connected to Azure should not have its address changed.

45. What is a guest OS in Microsoft Azure?

When we host a role instance in a virtual machine, the Guest OS is the OS that controls the VM.

46. What does a VNet mean?

 VNet stands for  Virtual Network. It is the cloud-based analog of your physical network. Our newly launched cloud instances can be logically isolated from the rest of your resources.

47. Is it possible to add an existing VM to an availability set?

No, it is not possible. They can only be included in an availability set if they are initially created within that set. We can't add a freshly created VM to an existing availability set.

48. How can I find a list of the already integrated Azure AD apps and what they can do?

Around 2600 applications are already set up to work with Azure AD. All the apps have already been connected to a single sign-on system (SSO). SSO lets use the login information for your organization to get into your apps. But some applications also allow provisioning and de-provisioning to be done automatically.

49. How many cloud service roles does Azure offer?

 Azure provides two types of roles:

• Worker role: These roles enable the applications they host to run asynchronously for long periods, unaffected by user interactions, and frequently not use IIS. They're also useful for background tasks. The programs operate independently of one another.
• Web role: This provides an IIS (Internet Information Services) dedicated web server to automatically deploy and host front-end websites.

50. What is Azure AD Multi-Factor Authentication?

In multi-factor authentication, a user must provide multiple forms of identification during sign-in. They might be asked to enter a code on their phone or scan their fingerprint.

While using Azure active directory multi-factor authentication, two or more of the following forms of authentication are needed:

• Usually, this is a password that you know.
• Something you have, like a phone or hardware key, that you trust and can't easily copy.
