Azure Fundamentals What are the main Azure DevOps services? Discuss Azure Boards, Azure Repos, Azure Pipelines, Azure Test Plans, and Azure Artifacts. Can you explain the difference between Azure App Service and Azure Functions? Explain the usage scenarios for each, highlighting their differences in terms of scalability, usage, and cost. CI/CD Pipelines How would you set up a CI/CD pipeline in Azure DevOps? Describe the steps involved in creating build and release pipelines using Azure Pipelines, integrating with version control systems, and deploying to Azure services. What are build agents in Azure DevOps? Discuss the purpose of build agents, the difference between Microsoft-hosted and self-hosted agents, and how to configure and manage them. Infrastructure as Code (IaC) How do you manage infrastructure as code in Azure? Explain the use of Azure Resource Manager (ARM) templates, Terraform, and other IaC tools in managing and deploying Azure infrastructure. Can you provide an example of an ARM template you’ve written? Be prepared to discuss a specific ARM template you’ve created, including its structure and key components. Automation and Scripting How do you automate tasks in Azure using PowerShell or Azure CLI? Provide examples of common automation tasks, such as provisioning resources, scaling services, and managing configurations. What is Azure Automation, and how have you used it? Explain the features of Azure Automation, such as runbooks, update management, and configuration management, and provide examples of how you’ve implemented them. Monitoring and Logging How do you monitor applications and infrastructure in Azure? Discuss the use of Azure Monitor, Azure Log Analytics, and Application Insights for monitoring performance, diagnosing issues, and gaining insights into applications. What are Application Insights and how do they integrate with Azure DevOps? Explain the purpose of Application Insights, its key features, and how it can be integrated with Azure DevOps for continuous monitoring. Security and Compliance How do you ensure the security of your Azure DevOps environment? Describe best practices for securing Azure DevOps, such as using service connections, managing access control, and implementing secure pipelines. What are Azure Key Vault and its uses? Explain the purpose of Azure Key Vault, how it helps in managing secrets, certificates, and keys, and provide examples of its integration with Azure DevOps. General DevOps Practices Describe your experience with version control systems in the context of Azure DevOps.
