Azure Interview Questions And Answers For Experienced And Freshers

Q 1- What is Microsoft Azure?

Microsoft Azure is a cloud service. Microsoft Corporation is the owner of this service. This is used to store data, compute it on the servers allocated by Microsoft. With the use of this service, we can design scalable and cost-effective applications to be deployed on the cloud.

Q 2– Compare AWS and Azure cloud services?

AWS of Amazon provides a Private Virtual Cloud, whereas Azure of Microsoft provides Network Virtual Cloud. AWS has 61 zones available, whereas Azure has 140 available zones.AWS provides a direct connection, while Azure offers an express connection. In AWS, all machines can be accessed separately as required. However, in Azure, different cloud services are grouped, and they respond to the same domain names but with other port numbers.

Q 3- What are the various services offered by the Azure cloud?

IAAS(Infrastructure As A Service): Using this service, you can use the infrastructure of the Azure cloud. You can configure their server as yours.

PAAS(Platform As A Service): Using this service, you can deploy your applications on Azure cloud environments without giving any permission to the software.

SAAS(Software As A Service): You get a chance to use the software applications on Azure by just paying rent for the time you are using them. This saves a lot of money spend on buying these applications.

Q 4- What are the different ways in which deployment can be done in Azure?

Public Cloud: Here, Azure is the owner of the infrastructure, and several companies are using their service.

Private Cloud: Here, the individual is the owner of the infrastructure, or you have the exclusive rights on the infrastructure provided by Azure. For example, you are hosting a website on the server only for you.

Hybrid Cloud: It’s a combination of Public and Private Cloud. For example, you are storing your private data on your owned servers and website hosting using the Public cloud.

51.  What Exactly is A SLA in Azure?

 

• When two or more role instances are placed on Azure, access to a cloud service is guaranteed to be available for at least 99.95% of the time under the terms of a contract known as the Azure Service Level Agreement (SLA).

 

• In addition, it states that processes that are not in the functioning state of the role instance will be identified and repaired 99.9% of the time, which is a very high percentage.

 

• If the guarantees above are not fulfilled at any point, Azure will credit us with a portion of our monthly costs, depending on the price structure of the applicable Azure services.

 

52. Azure Resource Manager: What is it?

The Azure Resource Manager is a service Azure offers to its customers to facilitate the management and deployment of applications under Azure.

 

The resource manager grants the developer privileges to the management layer, facilitating the developer’s ability to modify, add, or remove resources associated with an Azure subscription account. This functionality is quite helpful when we need to meet specific needs, such as controlling access restrictions and locks, assuring the safety of resources after they have been deployed, and organizing those resources.

 

53. What is The Optimal Azure Solution For Code Execution Without A Server?

 

• With the Azure Functions tool, you can run code without a server.

 

• Not a server Azure Functions make it easier to set up complicated orchestrations and solve challenging problems. They are meant to be without a state and only last briefly.

 

• They help you connect to other services without writing the integrations in code, which speeds up the creation process.

 

• It saves time and effort by letting the coder focus on writing the business logic code.

 

• As well as that, they offer Azure Application Insights for monitoring and analyzing code speed, which helps find slow spots and failure points in all parts of the application.

 

54.  Azure Blob Storage: What Is It?

 

1. Blue Sky Microsoft’s object storage service for the cloud is called blob storage.”Blob” is an abbreviation for “Binary Large Object.” .” Blob-based storage keeps substantial amounts of random text or binary data. It works great for sending files like text, images, audio, video, and documents straight to browsers.

 

2. You can access the info in the blob storage from anywhere worldwide. By putting the blobs into containers, you can link them to user accounts. The Azure Blob Service is divided into three sections:

 

• Storage Account: This could be a Blob Storage Account or a Microsoft Azure General Storage Account.

 

• Container: A container is a container that is used to group blobs.A container can accommodate an infinite number of aggregates. Initialise the container’s name with lowercase letters.

 

• Blob:Any binary large object, such as a file or a document, can be called a “blob.” Azure supports three different kinds of Blobs:

 

(i) Block blobs: Designed for text and binary files, these can accommodate up to 50k blocks with a maximum size of 4MB each or up to 195GB.

              (ii)        Appended blobs are utilized for tasks like data logging in log files.

                 (iii) Page blobs: These are designed to be read and written frequently.

 

55. When there isn’t enough staff to handle the influx of users, is there an Azure service that can help?

If you use VM Scale sets and set up the right setup and conditions, you can stop this problem by creating a new VM whenever the application’s load grows.

 

• With Azure VM Scale Sets, a developer can set up and control a group of load-balanced VMs. Scale sets can be configured to dynamically adjust the quantity of virtual machines (VMs) by the application’s requirements or a predetermined schedule.

 

• Scale Sets ensure that applications are always available and let developers control, update, and set up large virtual machines (VMs) from a central location. They also help developers build large-scale apps that handle much data, work, and computing power.

 

• Up to 1,000 VMs can run on Azure scale sets. There is a limit of 600 VMs if custom VM images are made and shared.

 

56. What could Cause A Client Application to Become Disconnected from its Cache?

There are two possible reasons for this:

 

1. Causes On The Client Side:

• Redeployment of the application is a plausible possibility.

 

• It could have been a scaling procedure by the application.

 

• The networking layer on the client side has undergone modifications.

 

• There may be short-term issues with the client or the network that links the client to the server.

 

• A further explanation can be that the bandwidth threshold restrictions have been exceeded.

 

2. Reasons From The Server End:

• The Azure Redis Cache service can fail from the primary node to the secondary node if the latter becomes unavailable.

 

• The cache’s server instance has been patched or maintained.
  
  57.Explain The Azure Table Storage Concept.

A schemaless architecture may store structured data in the cloud with Azure Table storage. It can store adaptable datasets such as address books, device information, user data for web applications, etc. An Azure table can hold any number of entities. Up to the storage account’s capacity limit, you can store unlimited tables in it.

 

Crucial Features of Azure Table Storage:

 

• Holds a lot of structured info that isn’t related to anything else

 

• It doesn’t have a structure, so you can change your data to fit your application’s needs.

 

• Gives a lot of client tools for Java, C++,.NET, Node.js, PHP, Python, and other languages that can be used to make apps.

 

• It costs less than standard SQL.
  
  58. What are Microsoft Azure Roles?

A role is a group of managed, load-balanced Platform-as-a-Service virtual machines that do the same jobs. The Azure fabric manager is in charge of them.

 

In Azure, there are three kinds of roles:

 

• Web Role: This is used to set up a website that uses languages like.Net and PHP that work with the IIS server. It has been changed so that web apps can run on it.

 

• Worker Role: This role is used to run tasks in the background.

 

• VM Role: It lets users plan when to do things and run Windows programs. It also enables you to change how the web and worker roles are run on the machines.
  
  
  59. What Exactly is Autoscaling? List Its Benefits.

Autoscale is a built-in feature of Azure that enables you to scale your application to achieve optimal performance while maintaining the optimal cost balance. When the demand varies, it can scale your application upwards or downwards according to your established criteria. It is an integral part of Azure and may be used for websites, virtual machines, mobile, and cloud services.

 

Advantages of Microsoft Azure Autoscaling include the following:

 

• Adjust your scale to meet the demand.

 

• Track essential performance indicators and receive notifications when anything changes.

 

• Economical: It automatically flakes unneeded instances.

 

• Optimizes the performance of the program

 61. What Distinguishes A Managed Disk from An Unmanaged One?

Managed Disks:

Creating a storage account is optional in order to utilize disks that Microsoft Azure maintains. Because Azure administers the storage account, you do not have full control over the disks generated in the account.

 

Unmanaged Disks:

To create a new storage account for an unmanaged drive, you must first create a storage account for the existing disk. Since you are the one who established and owns the storage account, you have complete authority over all of the information that is kept in that account. In addition, you will be responsible for handling matters about encryption, data recovery strategies, and so on.

 62. Azure Firewall: What Is It?

Firewalls on networks are essential to any data protection strategy an organization implements. Cloud-based firewalls in Microsoft Azure inspect the traffic based on the access control rules that administrators establish, much as traditional firewalls used in local area networks (LANs). In contrast to conventional firewalls, which frequently function as network perimeter security devices and points of termination for virtual private networks (VPNs), the Microsoft Azure Firewall offers role-based access control for ports and services determined by the level of your subscription.

63. Explanation of Azure Functions in Depth

Events and External-Invoke are two examples of serverless code computation services you may use with Azure Functions. Azure Functions are transient and stateless and can autonomously scale up in response to a request. They often expedite the development process because they save you from having to write any integration code to connect to other services. Additionally, they provide Azure Application Insights for code performance monitoring and evaluation, which helps locate failure sites and bottlenecks throughout the application’s parts. Functions may be implemented in Python, Java, Node.js, and C#, among others.

64. What is Your Knowledge Regarding Azure Active Directory?

Microsoft’s cloud-based authentication and authorization service is called Azure Active Directory (AD).  Identity protection, essential directory services, and application access management are all integrated into one system. It makes it possible for any worker in a company to log in and access the following resources:

 

i) Outside resources, including millions of additional SaaS services, Microsoft 365, and the Azure gateway.

 

ii) Internal resources, such as any cloud service apps developed by your firm and any apps on your intranet or network.

In addition to features like enterprise-grade privacy, fast scalability, SLA-backed availability, and single-digit millisecond response times, Azure Cosmos DB handles database administration tasks like auto-management, updates, etc.

 67. Describe Azure’s Site Recovery Functionality.

Site Recovery is a solution that ensures that business operations run smoothly by keeping corporate software and workloads active even in an outage. With the assistance of both physical and virtual machines (VMs), this feature made available by Azure can perform its function in a manner that copies activities from a primary place to a secondary location. If your primary location is unavailable, you will switch to the secondary location, from where you can access the applications.You can return to the initial location once it has been repaired. Site Recovery ensures replication for physical servers, virtual machines hosted on-premises, virtual machines hosted within Azure Stack, and Azure VMs.

 68. What does Azure Service Fabric Refer To?

A framework for parallel processing, the Azure Service Fabric ensures efficient packaging, deployment, and management of reliable microservices and containers. Service Fabric facilitates the development of applications based on microservices.In addition, Service Fabric handles the fundamental constraints that arise during the development and administration of cloud-native applications. Significant attention is placed on the creation of stateful services.

 

 The Service Fabric computing architecture enables the execution of container-based stateful services, irrespective of the programming language or code they are written in. Service Fabric clusters can be established in private clouds, Linux, and Windows Server, in addition to other public clouds.

 69. What Distinguishes Azure Load Balancer from Azure Traffic Manager?

Azure Data Manager’s main job is to send data worldwide based on changing rules. This makes the experience of the user better and shows how your app is used around the world. Your public connections will also benefit from being easy to reach and quick to respond. Traffic Manager provides a range of traffic-routing and endpoint-tracking options to meet the needs of different program goals and spontaneous recovery systems.

 

The Azure Load Balancer decides how data in a specific area is routed. The Azure data Manager sends data to a region between virtual machines when this is used with it. When you connect them, you get power over traffic worldwide with backup in your own area. The Azure Load Balancer service can handle both UDP and TCP protocols very fast and doesn’t use much data. As long as high availability is maintained, it can handle millions of searches per second without problems.

 70. What Does Azure Synapse Analytics’ Dedicated SQL Pool Mean?

You’ll get your own SQL pool when you use Azure Synapse Analytics for corporate data warehousing. A group of analytical tools used with Synapse SQL is called a “dedicated SQL pool.” The only ones who can decide how big a specialized SQL pool should be are Data Warehousing Units. After setting up the specialized SQL pool, you can use simple PolyBase T-SQL queries to bring in huge amounts of data and then use the distributed data processor to do fast analyses. An SQL pool is the only source your business can depend on for reliable high-speed insights as data is combined and analyzed.

 71. Describe Azure Backup. Mention Some of Its Benefits.

Microsoft provides Azure Backup, a cloud-based solution that lets you backup Azure File Shares, Azure Managed Disks, Azure SQL Server databases, Azure PostgreSQL databases, and Azure Windows virtual machines (VMs).

 

The following are some of Azure Backup’s main advantages:

 

• One straightforward approach to cloud backup of your on-premises data is with Azure Backup. You might obtain short-term and long-term backups without developing comprehensive on-premises backup solutions.

 

• Azure Backup allows for distinct backups to safeguard original data against unforeseen harm. The backups are saved in a storage device that is managed by Recovery Services and has an integrated recovery point system.

 

• Azure Backup uses the fundamental capabilities and limitless capacity of the Azure cloud to provide high availability with little upkeep or monitoring required.
  
  

 72. Talk About The Different Kinds of Backups That Azure Offers.

Azure Backup lets you back up your data in three different ways to keep your data and files highly available:

 

• Locally redundant storage (LRS) makes three copies of your data in a central storage unit in the same area. LRS is an inexpensive way to protect data from hardware failures in your area.

 

• The most popular and highly recommended data backup method is geo-redundant storage (GRS). It creates a copy of your files in another, less-accessible area. It costs more for GRS than for LRS, but it protects data better, even if there is a local problem.

 

• Zone-redundant storage (ZRS) copies data in available zones so that data stays safe and lasts for a long time in the same zone. Since ZRS has no delay, you can back up your essential tasks that need to keep data and can’t be interrupted.
  
  

 73. Which Kinds of Storage Services are Offered by Azure?

The following data options are available through the Azure Storage platform:

 

i  Azure Blob Storage—Azure Blobs is a powerful object storage that can hold both text and code data. It saves any data and lets you get it back as huge data blocks.

 

ii . Azure File Storage: Azure Files lets you share files securely in the cloud and on-premises.You can access fully managed cloud file shares from nearly anywhere using the standard Server Message Block (SMB) protocol.

 

iii. Azure Queue Storage—Azure Queues is a place where messages can be stored so that program modules can reliably talk to each other. Software units can use asynchronous message queuing to talk to each other.

 

iv. Azure Table Storage: You can store organized data without a schema in Azure Tables, a NoSQL database. It lets you store structured NoSQL data in the cloud and can store keys and attributes without using a model.

 

v. Azure Disk Storage: Azure Disks are block-level storage units for Azure VMs. They make it possible to store and get data from a virtual hard disk all the time.

 74. What are Azure Network Security Groups?

A network security group, also called an Access Control List, is a set of security policies that regulates the inbound and outbound traffic of a specific Azure resource. It is possible to connect subnets or individual NICs that are part of a subnet with NSGs so that the rules apply to all virtual machines in that subnet.  For each rule, you can define the sender address, the receiver address, the host, and the protocol.

 75. In Azure Active Directory, Define Application Partitions.

Azure Active Directory’s application partitions are subsets of the directory that are copied to local DCs. These domain controllers maintain a replica of the partition as they participate in the partitioning process. One potential benefit of application partitions is their capacity to be duplicated to a specific domain controller, which may decrease network traffic.Domain directory partitions can transfer their complete data to all domains, while domain area application partitions are limited to targeting a single domain.  By reducing the necessity for application partitions, their availability is enhanced.

 76. Talk About The Azure Kubernetes Service (AKS) in Brief.

The purpose of the Azure Kubernetes Service (AKS) is to simplify the process of deploying a Kubernetes cluster under management on Azure.It alone is capable of managing containerized applications. It’s an open-source way to automatically manage traffic, scale, and install software. As a controlled Kubernetes service, Azure takes care of essential tasks like testing and managing health. The Kubernetes masters are managed by Azure, leaving you with only the agent nodes to worry about. This is why AKS is completely costless, and you need only pay for the agent nodes that make up your groups.

77. How Does One Acquire The Privileges of An Administrator On The Azure Portal?
