COGNIZANT AZURE INTERVIEW QUESTIONS

Here is the list Azure Interview Questions which are recently asked in Cognizant company. These questions are included for both Freshers and Experienced professionals.

1. What is the difference between Public Cloud and Private Cloud?

A private cloud is a cloud service that is not shared with any other organization. By contrast, a public cloud is a cloud service that shares computing services among different customers, even though each customer’s data and applications running in the cloud remain hidden from other cloud customers.

2. How to design applications to handle connection failure in Windows Azure?

Key points

Uncover issues or failures in the application’s retry logic.
Configure request timeouts to manage inter-component calls.
Implement retry logic to handle transient application failures and transient failures with internal or external dependencies.

3. What is Windows Azure Diagnostics?

The Azure Diagnostics VM extension enables to collect monitoring data, such as performance counters and event logs, from the Windows VM. You can granularly specify what data you want to collect and where you want the data to go, such as an Azure Storage account or an Azure Event Hub.

4. What is the difference between Windows Azure Queues and Windows Azure Service Bus Queues?

Service Bus Queue is part of a broader messaging service that supports queuing, publish/subscribe, and more advanced integration patterns. Azure Storage Queues are simpler to use but are less sophisticated and flexible than Service Bus queues.

5. What are the instance sizes of Azure?

Type	Sizes
General purpose	B, Dsv3, Dv3, Dasv3, Dav3, DSv2, Dv2, Av2, DC
Compute optimized	Fsv2
Memory optimized	Esv3, Ev3, Easv3, Eav3, Mv2, M, DSv2, Dv2
Storage optimized	Lsv2

6. What is table storage in Windows Azure?

Azure Table storage is a database used to store NoSQL data in Azure. It enables to store structured, schema less data using a key/attribute design and can be used for structured, non-relational data. Use Azure Table storage through the Azure Cosmos DB Table API.

7. What Is Windows Azure Compute Emulator?

The Microsoft Azure Storage Emulator is a tool that emulates the Azure Blob, Queue, and Table services for local development purposes. You can test your application against the storage services locally without creating an Azure subscription or incurring any costs.

8. What Are The Options To Manage Session State In Windows Azure?

In-Proc, which stores session state in the individual web server’s memory.
State Server, which stores session state in another process, called ASP.NET state service.
SQL Server, which stores session state in a SQL Server database.

9. What Is Web Role In Windows Azure?

Web Role is a Cloud Service role in Azure that is configured and customized to run web applications developed on programming languages/technologies that are supported by Internet Information Services (IIS), such as ASP.NET, PHP, Windows Communication Foundation and Fast CGI.

10. What Is The Difference Between Public Cloud And Private Cloud?

Private Cloud is the cloud services used by a single organization, which are not exposed to the public. A private cloud resides inside the organization and must be behind a firewall, so only the organization has access to it and can manage it. Public cloud is cloud computing that’s delivered via the internet and shared across organizations. Example: AWS

11. What Is Windows Azure Diagnostics?

The Azure Diagnostics VM extension enables to collect monitoring data, such as performance counters and event logs, from the Windows in Azure Monitor that collects monitoring data from the guest operating system of Azure compute resources including virtual machines.

14. What Is Azure Fabric Controller?

Azure Fabric Controller is a native component of Azure Service Platform that manages the hardware resources provisioned for hosted software applications. It acts as the kernel of Azure Service Platform in managing the hardware resources.

15. What Is Autoscaling?

Auto scaling is a cloud computing technique for dynamically allocating computational resources. Auto scaling and load balancing are related because an application typically scales based on load balancing serving capacity.

16. What Is Vm Role In Windows Azure?

The Windows Azure VM role allows to run a virtual hard disk image, store that image in the cloud and load and run it on demand. Enter the Windows Azure Virtual Machine (VM) Role, which allows running a customized instance of Windows Server 2008 R2 in Windows Azure, making it easier to move applications to the cloud.

17. How Would You Categorize Windows Azure? (iaas/paas/saas)?

While each Azure Compute offering has their pros and cons, I prefer to build my projects around PaaS – Cloud Services. With PaaS, we can get the maximum possible amount of flexibility before start worrying about the tedious world of OS maintenance, versions, security, patches, etc.

18. What Is Azure Cloud Service?

Azure is Microsoft’s big enterprise cloud, offered as a PaaS and IaaS service. It is a popular service used by developers who write apps with the support of the company’s coding tools.

19. What Is A Cloud Service Role?

20. What Is Scale A Cloud Service ?

Scaling is the process of adding or removing compute, storage, and network services to meet the demands a workload makes for resources in order to maintain availability and performance as utilization increases.

21. What Is Azure Diagnostics ?

Microsoft Azure Diagnostics (WAD) enables to collect diagnostic data from Cloud Services running in Microsoft Azure. WAD fulfills two new diagnostic gathering requirements introduced by the Microsoft Azure scale-out architecture: Save diagnostic data that would be lost during a reimaging of the instance.

22. What Is Azure Service Level Agreement (sla)?

A Service Level Agreement or SLA is a formal document that provides specific terms that state the level of service that will be provided to a customer. Microsoft’s Azure SLA defines three primary characteristics of Azure service, performance targets, uptime, and connectivity guarantees.
