Let’s go through the top 30 latest Azure Interview questions & answers in the below section of the post. I hope these questions are helpful. Let us know if you would like to add additional details to questions and answers.
What are the different computing options available in Azure?
There are multiple computing options available. The main compute options include virtual machines (VMs), Azure Functions, Azure Container Instances, Azure Kubernetes Service (AKS), and Azure Batch.
What is the difference between Azure Virtual Machines (VMs) and Azure Functions?
Azure Virtual Machines (VMs) are infrastructure-as-a-service (IaaS) offerings that provide virtualized hardware resources for running applications. VMs offer more control and flexibility, allowing users to manage the operating system and the application stack.
There could be some indirect Azure Interview Questions for System Admin, so you need to be prepared for those indirect and scenario-based questions.

Can you explain the concept of auto-scaling in Azure?
Auto-scaling in Azure is the ability of a compute resource to adjust its capacity based on the workload demand automatically. Azure provides different kinds of auto-scaling options depending on the computing service. For example, Azure Virtual Machine Scale Sets allow you to define scaling rules based on CPU utilization, memory usage, or custom metrics.
Azure App Service has built-in auto-scaling capabilities that can be configured based on predefined rules or metrics. Auto-scaling helps ensure that the compute resources are efficiently utilized, can handle fluctuations in workload, and allows the customer for high availability of their applications.

How do Azure Container Instances differ from Azure Kubernetes Service (AKS)?
Azure Container Instances (ACI) and Azure Kubernetes Service (AKS) are computed options for running containerized applications but have different use cases. Azure Container Instances is a serverless offering that allows users to run containers without managing the underlying infrastructure. It is best suited to scenarios where you need a lightweight and simple way to run individual containers.
Azure Kubernetes Service (AKS) is a managed container orchestration service that provides a full-fledged Kubernetes environment. AKS is mostly suitable for running complex applications that require container orchestration, scaling, and management capabilities.

How does Azure App Service differ from Azure Virtual Machines (VMs)?
Azure App Service and Azure Virtual Machines (VMs) are different computing options in Azure. Azure App Service is a platform-as-a-service (PaaS) offering that allows you to host web applications, mobile app backends, and RESTful APIs. It abstracts away the underlying infrastructure management, providing a fully managed environment for application hosting.
Azure App Service supports multiple programming languages, automated scaling, deployment slots, and integration with other Azure services. On the other hand, Azure Virtual Machines (VMs) offer more control and flexibility, as they provide virtualized hardware resources on which you can install and manage the operating system and application stack directly.
You should not mug up Azure Interview Questions and Answers. Rather you should understand the concept and then try to answer the questions.

What are the advantages of using Azure Functions over Azure Virtual Machines (VMs) for running code?
Azure Functions offer several advantages over Azure Virtual Machines (VMs) for running code. Azure Functions are serverless, so you don’t have to worry about infrastructure management. They automatically scale based on the workload and charge you only for execution time. This makes Azure Functions more cost-effective for workloads with sporadic or unpredictable demand.
Additionally, Azure Functions provide easy integration with various triggers and events, enabling event-driven architectures. They also support different programming languages and have built-in integrations with other Azure services, making building serverless applications and microservices easier.

What are the key features and capabilities of Azure Virtual Machines?
Azure Virtual Machines (VMs) offer several key features and capabilities. VMs provide flexibility in choosing the size and configuration of virtual machine instances based on your workload requirements. They support various operating systems, including Windows, Linux, and specialized OS images from the Azure Marketplace.
VMs offer different storage options, including managed disks and Azure Blob storage. You can use features like virtual machine scale sets for automatic scaling, Azure Reserved VM Instances for cost optimization, and Azure Spot VMs for obtaining VM capacity at a significant discount.

How does the Azure VM scale set help with scalability and availability?
Yes, Azure Virtual Machine Scale Sets automatically scale a group of virtual machines based on demand. Scale sets allow you to define scaling rules based on CPU utilization, memory usage, or custom metrics. Azure automatically adds new VM instances to the scale set as the load increases.
This helps your application handle increased traffic or workload by distributing it across multiple VMs. Scale sets also provide high availability by distributing VM instances across fault and update domains, ensuring your application remains available even if a VM or underlying hardware fails. Additionally, you can leverage Azure Load Balancer with scale sets to evenly distribute incoming network traffic.

How can you distribute traffic across different regions for high availability and performance?
To distribute traffic across different regions in Azure for high availability and performance, you can leverage Azure Traffic Manager. Traffic Manager is a DNS-based traffic load balancer that directs client requests to the most suitable endpoint based on routing methods such as priority, performance, or geographic proximity.
By configuring Traffic Manager with endpoints in different Azure regions, you can distribute traffic to the closest and best-performing part. This helps improve availability and reduce latency for users accessing your services from other geographic locations.

How can you automatically scale Azure Virtual Machines based on CPU utilization?
Azure Virtual Machine Scale Sets allow you to achieve automatic scaling of VMs based on CPU utilization. With Scale Sets, you can define scaling rules that specify the minimum and maximum number of VM instances based on CPU metrics.
When the CPU utilization exceeds a certain threshold, Azure automatically adds more VM instances to the scale set to handle the increased load.
Conversely, when the CPU utilization drops below a specified threshold, Azure removes VM instances from the scale set to optimize costs. This enables you to automatically scale your compute resources based on demand while ensuring optimal performance and cost-efficiency.
