Staging environment: This is where modifications to an application are tested before going live.

Applications are launched in the production environment, where target consumers can access them using DNS-friendly URLs.

26. What is Blob Storage Azure?

The cloud's object storage option is Azure Blob (binary huge object) storage. It is suitable for sending documents, media, or text straight to the browser and has the capacity to store vast amounts of unstructured data in text or binary format. The information is available everywhere. The containers and user accounts are connected to the blobs. This service can be categorized into three parts:

Storage account: This might be a Microsoft Azure-registered blob storage account or a standard storage account.
Containers are used to aggregate blobs together. Blobs can be stored indefinitely in each container. The name of the container needs to be lowercase.
A blob is any form of file or document, regardless of size. Azure supports the following three types of blobs:
Blobby blocks: Up to 195GB of text and binary data, in 50,000 blocks no larger than 4 MB each
Attach blobs: actions that are appended, such as logging data in log files
Blobby pages: whenever you frequently read or write

27. Explain the role of instance in Azure?

A role instance is a virtual machine where running role configurations are used to execute application code. The definition of a role in cloud service configuration files also permits multiple instances of a role.

28. What is Windows Azure Portal?

A designer accesses the Windows Azure Portal through his or her web program and logs in using a Windows Live ID to execute an application. At that point, the user can decide whether to set up a hosting account for running programs, a storage account for storing data, or even both. A designer can use a Windows Azure Portal to submit apps to Windows Azure if they have a hosting account.

29. What are your understandings of hybrid clouds?

A hybrid cloud is made up of both internal and external cloud resources, combining private and public cloud resources.

When you need to store sensitive information close at hand (private cloud) while using different services from a public cloud, this type of cloud is ideal.

30. Explain Azure Fabric?

Azure Fabric forms the core idea in Azure. It offers an Azure Fabric controller series as it manages or oversees the following:

Each and every processing role and resource
Activating and sending services
Keeping track of each service's condition
Resource allocation and release

The most automatic method for updating patches for the installed OS on a virtual machine

31. Define a storage key?

In order to control data based on our requirements, storage keys or access keys are used as a validation technique for accessing the storage services account. Although we will only use one access key to verify our application to the storage, Windows Azure gives us the option to provide a primary access key and a secondary access key. Giving the secondary access key is mostly done to keep the program from going offline.

32. Explain Windows Azure Traffic Manager?

It gives users the ability to manage how user traffic for deployed Azure cloud services is distributed. Azure offers three different types of load-balancing techniques. The manager who handles traffic routes Domain Name Service (DNS) inquiries on your domain names according to a routing policy and associates the DNS paths with the appropriate instances of your applications.

33. What does SQL Azure federation mean?

Scalability is achieved in SQL Azure by introducing organization. Managers and developers can scale information with the aid of a federation. It benefits managers by making information repartitioning and redistribution easier. It gives developers the ability to share and route information. It facilitates routing without a pause in the program.

34. Briefly explain SQL Azure Database?

The SQL Azure database is merely a means of connecting to cloud services so that your database can be stored there. The best way to use PaaS where you can have multiple databases on the same account is using Microsoft Azure. Similar to SQL Server, Microsoft SQL Azure features excellent accessibility, adaptability, and security at its heart. The Microsoft Azure SQL Database offers a feature that automatically creates backups of all active databases. To support the 1-hour recovery point goal (RPO) for Geo-Restore, a backup is regularly obtained and geo-repeated.

35. What kinds of storage areas are there in Windows Azure?

A component for storing large amounts of content or binary data, such as images, audio files, and visual documents, is provided by BLOBs. They can be acquired by using REST APIs and are scalable up to 200 terabytes.

53. What does the Azure Machine Text Analytics API do?

The content analysis web services integrated with Azure Machine Learning include the Content Analytics API. The API can be used to do tasks like sentiment analysis and key-phrase extraction on unstructured information.

The API retrieves a score in the range of 0 and 1. Scores close to 1 indicate an optimistic attitude, while those close to 0 indicate a negative attitude.

The benefit of this API is that the user only needs to supply the data and use the service to obtain the sentiment results—another new model doesn't need to be created and prepared.

54. What does Azure Websites' Migration Assistant tool do?

The IIS installation will be examined by the Migration Assistant tool, which will identify the sites that can be moved to the cloud and highlight any components that cannot be moved or are not supported by the platform.

After being disassembled, this tool will also generate the sites and databases that are included in the supplied Azure membership.

55. What distinguishes a private cloud from a public cloud?

A private cloud is implemented inside certain parameters like firewall settings and is completely monitored and checked by the users dealing with it in an enterprise. A public cloud is used as a service through the Internet by users.

56. What is a Service Level Agreement (SLA) for Azure?

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

Azure Interview Questions Based on Scenario

63. In the absence of a server, how will Azure assist in running code?

Code can run on Azure Functions without a server. These services streamline challenging orchestration tasks. They aid in establishing connections with other services without requiring hard coding of integrations, hastening the development process.

Developers can spend more time and effort writing code for the business logic. With the aid of Azure Application Insights, you can examine and track the performance of your code as well as spot bugs and potential failure areas in different application parts.

64. What might have caused the client application to lose connection to the cache?

There are two potential causes:

Client-end

Application redeployment
Operational scaling by application
Client-side networking layer modification
Momentary issues with the client or the client-server network
Exceeding bandwidth threshold restrictions

Server-end

Sky Redis: A failover occurred for the cache service from the primary node to the backup node.
Patching or maintenance was performed on the server instance where the cache was installed.

65. How can the high load problem on an application be resolved when there is no man assistance on the flow?

When there is a heavy load, Azure VM Scale Sets can be used to provide the appropriate parameters and circumstances and deploy a new VM.

A set of load-balanced virtual machines can be created and managed by a developer using VM Scale Sets. The scale sets can be set up to automatically modify the number of VMs in accordance with a specified timetable or the application's demand.

The use of scale sets ensures that the applications are highly available and makes it possible for huge VMs to be managed, updated, and configured centrally. Additionally, it facilitates the creation of large-scale applications using big workloads, big data, and computational loads. For Custom Images Azure Scale Sets accommodate up to 1,000 VMs and 600 VMs.

66. What will you do if your drive malfunctions?

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

Make sure the drive is not installed to ensure that Azure Storage always works as intended.

Changing the drive will cause it to be remounted and formatted.

67. What would occur if the tone had the maximum number of failed Azure ID authentication attempts?

In this case, the Azure account will be locked based on the protocol's analysis of the entered IP address and password from which the login request was made.

68. How will you differentiate Azure Scale Sets from Availability Sets?

The significant variation between the two lies in the VMs. While Scale sets have identical VMs, Availability sets do not necessarily require VMs to be identical. Several other distinctions can be dissected in the following criteria:

Default Domain: In scale sets, there are 5 update and fault domains while Availability sets features and 5 update domains, and 3 fault domains.
Workload Type: Scale Sets are utilized in the events of unpredictable workloads that also need auto scalability. On the contrary, Availability sets are employed when there is the requirement of auto scalability.
Configuration Style: Scale sets feature VMs that are similar in configuration for similar images while Availability sets employ varying configurations and images.
VM Count: Scale sets have the flexibility of increasing or decreasing the VMs number as per the demand or the predetermined schedule. While in the Availability set, a VM can only be added during the period of creating the sets.
Distribution Style: The VMs in the Scale set could be split over several data centers or kept in a single one. The VMs in a data center are automatically distributed in Available sets.

69. What do application partitions represent?

The application partitions are directory partitions that are replicated to domain controllers since they are a component of the Active Directory system. A replica of the directory partition is typically kept on each domain controller involved in the directory partitioning procedure. Application partitions have the benefit of being replicable to any individual domain controller inside a forest, which reduces replication traffic. The application partitions can concentrate on just one domain area while the domain directory partitions transport all of their data to all of the domains. Application partitions become unnecessary and more available as a result.

70. How can the high load problem on an application be resolved when there is no man assistance on the flow?

When there is a heavy load, Azure VM Scale Sets can be used to provide the appropriate parameters and circumstances and deploy a new VM.

The use of scale sets ensures that the applications are highly available and makes it possible for huge VMs to be managed, updated, and configured centrally. Additionally, it facilitates the creation of large-scale applications using big workloads, big data, and computational loads. Azure Scale Sets accommodate around 600 VMs for bespoke VM images and up to 1,000 VMs.

71. What would occur if the tone had the maximum number of failed Azure ID authentication attempts?

In this case, the Azure account will be locked based on the protocol's analysis of the entered password and the IP address from which the login request was made.

72. Will you be able to access an application via the Azure environment in the event that the on-premise server application access fails if you have an application operating on the on-premise server and the Azure East US region has a backup?

Yes. The Azure Site Recovery Service can be used to access the application. Between on-premise servers and Azure environments, it can manage fail-over and fail-back scenarios.

73. How will you handle the Azure Connectivity if the front-end hosting of the application is done on Azure while the user needs the database hosting to be done on an on-premise server owing to security concerns?

The issue can be fixed by several ways including the following:

One on-premises DB can be connected to an Azure-hosted application using the point-to-site service based on the Azure VNET architecture. This is true when using a VPN requires a lot of resources.
Site-to-site or rapid routes are the answer when there are more resources needed for connection. Network latency may be impacted by site-to-site because the VPN only uses the internet as its public infrastructure. Express routes can be employed in that situation because they have a dedicated leased line that addresses latency problems.
Windows Communication Foundation (WCF) services can be created and hosted on-premises if VNET is not preferred. It will feature CRUD operations made specifically for the locally hosted database. For Database access, it takes advantage of the service bus relay to establish a connection between the Azure-hosted app and the WCF service.
