Microsoft Azure Interview Questions for Beginners
1. What are the various Cloud Deployment Models?
The three cloud deployment models are as follows:
Public Cloud: Cloud provider owns the infrastructure, and the server someone’s utilizing could be a multi-tenant system.
Private Cloud: You control the infrastructure, or your cloud provider provides you with that service solely. For instance, one might host their website on their own servers or with a cloud provider on a dedicated server.
Hybrid Cloud: It refers to the usage of both public and private clouds at the same time. For instance, use your in-house servers for secret data and the public cloud to host your company’s public-facing website. It is a hybrid cloud configuration.
2. What do you mean by Azure Virtual Machine Scale Sets?

- The second alternative is to replace the drive, in which case you need to remount and format the drive.
45. What should one do in the event of a Service Failure?
One can take the following measures in the event of a service failure:
- Ascertain that the object’s services have terminated, allowing the object services to survive the failure.
- Allowing the system object storage to stay functioning while completing the last lap of work pending can be accomplished by bringing the machine back online. The online replication will automatically activate with the missing updated files once they are started.
- If you are unable to replace the drive, in this case, remove it and leave the system unmounted.
46. What is cmdlet in Azure?
A cmdlet is a small command that runs in the Microsoft PowerShell environment. The cmdlets are called by Windows PowerShell to automate scripts that are run from the command line. Additionally, the Windows PowerShell runtime calls them using Windows PowerShell APIs.

You appreciate the ease of searching and exporting data from a single dashboard.
58. Define Availability Set.
It is a logical grouping of virtual machines that enables Azure to understand how your application is constructed for redundancy and availability. To ensure a highly available application and to achieve the 99.95 percent Azure SLA, two or more VMs should be established within an availability set. When using Azure Premium Storage with a single VM, the Azure SLA applies to unscheduled maintenance occurrences.
59. 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. The cloud service roles must have Azure Diagnostics enabled. The information gathered can then be used to build visual chart representations for enhanced monitoring and performance metric alerts.
