Q1. What is Azure Resource Manager (ARM) and how does it helpmanageresources in Azure?
Answer: Azure Resource Manager (ARM) is a deployment and management system that provides a consistent management process for resourcesinAzure. 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 viewof 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 ownelectricity,cooling and network infrastructure.
Applicationscanachievemaximumcapacityandflexibilityby distributing resources across multiple regions. Azure Availability Zones provide fault tolerance by preventingdatacenter-levelfaults. Services suchas virtual machines, managed disks, and parallelproductsareavailablein 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 inAzure without management or configuration. With Azure Functions, you can write code in different programming languages and respond to events from a varietyofsources,suchas 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 sitemanagement, continuous integration/continuous delivery (CI/CD), project management, and more. Azure DevOps integrates with a varietyof Azure services and third-party toolstoprovideintegration,workflow, and maintenance throughout the software development process. Histeamembraces DevOps practices, streamlinesoperations and deliversappsfaster, with betterperformance 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. Virtualnetworks provide segmentation and managementof network connections within Azure and within Azure and theenvironment. Key features of a VNet include subnetting, NetworkSecurityGroups (NSGs) for traffic filtering, virtual private network (VPN) gateways for secure connectionsto on-premises networks, and Azure ExpressRoute for personal connections. VNetsupportsthesecurity and managementof network connections, allowing you to create a network connection while maintaining isolation and connectivity.
