– Answer: Azure AD Connect is a tool that synchronizes on-premises Active Directory with Azure Active Directory, allowing for a single identity for accessing both cloud and on-premises resources.
- Explain Azure Regions and Availability Zones.
– Answer: Azure Regions are geographical areas containing data centers, while Availability Zones are physically separate locations within a region, each with independent power, cooling, and networking.
- How do you monitor Azure resources for performance issues?
– Answer: Azure Monitor collects and analyzes telemetry data from Azure resources, providing insights into performance metrics, logs, and alerts.
- What is Azure Virtual Machine Scale Sets?
– Answer: Azure Virtual Machine Scale Sets allow you to create and manage a group of identical, load-balanced VMs that can automatically scale based on demand or schedule.
- What are Azure Policies and Initiative Definitions?
– Answer: Azure Policies enforce rules and effects over resources to ensure compliance, while Initiative Definitions group related policies together for easier management.
- How do you secure Azure Storage accounts?
– Answer: Azure Storage accounts can be secured using access keys, Shared Access Signatures (SAS), Azure RBAC, and Azure AD authentication.
- What is Azure Key Vault and why is it important?
– Answer: Azure Key Vault is a service for securely storing and managing secrets, keys, and certificates. It helps protect sensitive information and simplifies key management tasks.
- Explain the difference between Azure Backup and Azure Site Recovery.
– Answer: Azure Backup is used for backing up data and VMs to Azure, while Azure Site Recovery is used for disaster recovery, replicating VMs and applications to Azure or another datacenter.
- How do you deploy a highly available web application in Azure?
– Answer: You can deploy a highly available web application using Azure App Service with multiple instances, Azure Traffic Manager for global load balancing, and Azure SQL Database for the backend.
- What is Azure DevOps Pipelines used for?
– Answer: Azure DevOps Pipelines is used for automating the build, test, and deployment of applications, enabling Continuous Integration (CI) and Continuous Deployment (CD) workflows.
- How do you manage network security in Azure?
– Answer: Network security in Azure can be managed using Network Security Groups (NSGs), Azure Firewall, Azure DDoS Protection, and Azure Virtual Network Service Endpoints.
- Explain the concept of Azure Resource Groups.
– Answer: Azure Resource Groups are containers that hold related resources for an Azure solution. They allow you to manage and monitor resources as a single entity, including applying access control and tags.
- What is Azure Managed Disks?
– Answer: Azure Managed Disks are block storage disks for Azure VMs that are managed by Azure, eliminating the need to manage storage accounts and simplifying disk management tasks.
- How do you automate Azure tasks using PowerShell?
– Answer: Azure tasks can be automated using Azure PowerShell cmdlets, which interact with Azure Resource Manager to manage resources, configure settings, and deploy solutions.
- What is Azure Virtual Network Peering?
– Answer: Azure Virtual Network Peering enables connectivity between virtual networks in the same region, allowing resources to communicate securely without the need for a VPN gateway.

Azure DevOps Concepts:
- What is Azure DevOps?
– Answer: Azure DevOps is a suite of cloud-based collaboration tools for software development, including version control, build automation, release management, and project management.
- Explain the components of Azure DevOps.
– Answer: Azure DevOps consists of Azure Repos, Azure Pipelines, Azure Boards, Azure Artifacts, and Azure Test Plans.
- What is Azure Repos, and what types of version control systems does it support?
– Answer: Azure Repos is a version control service that supports two types of version control systems: Git and Team Foundation Version Control (TFVC).
- What are the benefits of using Git version control in Azure Repos?
– Answer: Git in Azure Repos provides distributed version control, branching and merging capabilities, collaboration features, and integration with Azure Pipelines.
- How does Azure Pipelines facilitate Continuous Integration (CI) and Continuous Deployment (CD)?
– Answer: Azure Pipelines automates build and release processes, enabling CI by automatically building and testing code changes and CD by deploying code changes to target environments.
- What is a pipeline in Azure Pipelines?
– Answer: A pipeline in Azure Pipelines defines a series of steps to build, test, and deploy applications. It can include tasks for building code, running tests, and deploying artifacts.
- How do you define build and release pipelines in Azure DevOps?
– Answer: Build and release pipelines in Azure DevOps are defined using YAML or the visual designer in the Azure DevOps portal.
- What is an Azure DevOps Agent, and what are its types?
– Answer: An Azure DevOps Agent is a software agent that runs build and release tasks. It comes in two types: Microsoft-hosted agents and self-hosted agents.
