Q1. What is Azure Resource Manager (ARM) and how does it help manage resources in Azure?

Answer: Azure Resource Manager (ARM) is a deployment and management system that provides a consistent management process for resources in Azure. It allows you to create, modify, and delete resources as a group called a group. ARM standards written in JSON define the desired state of a process and allow reporting and management.

ARM simplifies asset management by providing a unified view of resources, their dependencies and lifecycles.

Q2. Explain the concept of Azure Availability Zones and how they improve availability in Azure.

Answer: Azure Availability Zones are physically reserved data locations in Azure regions. Each region has its own electricity, cooling and network infrastructure.

Applications can achieve maximum capacity and flexibility by distributing resources across multiple regions. Azure Availability Zones provide fault tolerance by preventing datacenter-level faults. Services such as virtual machines, managed disks, and parallel products are available in Availability Zones for redundancy and application availability even in the event of a zone failure.

Q3. What is Azure Functions and how does it support serverless computing?

Answer: Azure Functions is a serverless service that provides event-driven, on-demand execution in Azure without management or configuration. With Azure Functions, you can write code in different programming languages ​​and respond to events from a variety of sources, such as HTTP triggers, queues, timers, and more. Functions automatically scale on demand and execute stateless code, allowing developers to focus on writing code without worrying about the underlying process.

Q4. What is Azure DevOps and how does it support the DevOps lifecycle?

Answer: Azure DevOps is a set of development tools and services that support the entire DevOps lifecycle. It provides site management, continuous integration/continuous delivery (CI/CD), project management, and more. Azure DevOps integrates with a variety of Azure services and third-party tools to provide integration, workflow, and maintenance throughout the software development process. His team embraces DevOps practices, streamlines operations and delivers apps faster, with better performance and reliability.

Q5. Explain the concept of Azure Virtual Network (VNet) and its role in network isolation and connectivity.

Answer: Azure Virtual Networks (VNets) allow you to create isolated network environments in Azure. Virtual networks provide segmentation and management of network connections within Azure and within Azure and the environment. Key features of a VNet include subnetting, Network Security Groups (NSGs) for traffic filtering, virtual private network (VPN) gateways for secure connections to on-premises networks, and Azure ExpressRoute for personal connections. VNet supports the security and management of network connections, allowing you to create a network connection while maintaining isolation and connectivity.
