Azure Basics
- What is Azure?
- Azure is a cloud computing platform by Microsoft that provides a range of cloud services, including compute, storage, databases, networking, and more.
- Explain Azure Resource Manager (ARM).
- ARM is the deployment and management service for Azure. It provides a way to deploy and manage resources in Azure using templates.
- What is Azure DevOps?
- Azure DevOps is a set of services for collaboration, development, and deployment of applications in the cloud. It includes CI/CD pipelines, repositories, testing tools, and more.
- Differentiate between Azure Service Manager (ASM) and Azure Resource Manager (ARM).

Azure DevOps Concepts
- What are the key components of Azure DevOps?
- Azure Pipelines, Azure Repos, Azure Boards, Azure Artifacts, and Azure Test Plans.
- Explain Continuous Integration (CI) and Continuous Deployment (CD).
- CI is the practice of automating builds and tests whenever code is changed. CD extends CI by automatically deploying code to production environments after passing tests.
- How do you integrate Azure DevOps with Azure services?
- Azure DevOps integrates with Azure services through service connections, allowing pipelines to interact with Azure resources like VMs, databases, etc.
- What is YAML in Azure Pipelines?
- YAML is a markup language used to define CI/CD pipelines in Azure DevOps. It allows specifying build and release tasks declaratively.
- Explain the concept of artifacts in Azure DevOps.
- Artifacts in Azure DevOps are packages (e.g., NuGet, npm) produced by builds that can be used as dependencies in subsequent stages of the pipeline.

Azure DevOps Pipelines and Builds
- What are the different types of triggers in Azure Pipelines?
- Triggers include code triggers (e.g., branch filters, path filters), schedule triggers, and manual triggers.
- How do you handle secrets in Azure Pipelines?
- Use Azure Key Vault or pipeline variables marked as secrets to store and access sensitive information securely.
- Explain multi-stage pipelines in Azure DevOps.
- Multi-stage pipelines allow defining complex workflows with multiple stages and environments in a single YAML file.
- What is a release pipeline in Azure DevOps?
- A release pipeline in Azure DevOps defines the process for deploying applications and services to a target environment.
Azure DevOps Monitoring and Optimization
- How do you monitor Azure DevOps pipelines?
- Use Azure Monitor to track pipeline runs, monitor resource usage, and set up alerts for pipeline failures or performance issues.
- What are deployment gates in Azure DevOps?
- Deployment gates are automated checks (e.g., performance tests, approvals) that occur before or after a deployment to ensure quality and reliability.
- Explain Azure DevOps integration with monitoring tools.
- Azure DevOps integrates with tools like Azure Monitor, Application Insights, and third-party monitoring solutions for tracking application performance and health.
Azure DevOps Collaboration and Reporting
- How do you manage work items in Azure DevOps?
- Use Azure Boards to create, track, and manage work items (e.g., user stories, tasks, bugs) across your project.
- Explain the use of dashboards and reports in Azure DevOps.
- Dashboards and reports in Azure DevOps provide visualizations and insights into project progress, team performance, and work item trends.
- How can you integrate Azure DevOps with third-party tools?
- Azure DevOps supports integrations with various tools and services through REST APIs, webhooks, and marketplace extensions.
Azure DevOps Best Practices and Troubleshooting
- What are branching strategies, and why are they important in Azure DevOps?
- Branching strategies define how code changes are managed across different branches (e.g., feature branches, release branches) to facilitate collaboration and stability.
- How do you troubleshoot a failed build in Azure Pipelines?
- Review build logs, examine error messages, and check for issues with dependencies, permissions, or configuration settings in the pipeline.
- Explain blue-green deployments and how they can be implemented in Azure DevOps.
- Blue-green deployments involve running two identical production environments, allowing seamless deployment and rollback capabilities using Azure DevOps release pipelines.
Azure DevOps Integration with Other Services
- How do you deploy Docker containers using Azure DevOps?
- Use Azure DevOps pipelines to build Docker images, push them to a container registry (e.g., Azure Container Registry), and deploy containers to Azure Kubernetes Service (AKS) or Azure App Service.
- What is Azure Kubernetes Service (AKS), and how can you integrate it with Azure DevOps?
- AKS is a managed Kubernetes service in Azure. Integrate AKS with Azure DevOps to automate deployment, scaling, and management of containerized applications using Kubernetes.
Azure DevOps Advanced Topics
- Explain Infrastructure as Code (IaC) and its benefits in Azure DevOps.
- IaC involves managing and provisioning infrastructure using machine-readable files (e.g., ARM templates) rather than manual processes, ensuring consistency and reproducibility.
- How do you implement automated testing in Azure DevOps pipelines?
- Use tasks in Azure Pipelines to run unit tests, integration tests, and UI tests automatically as part of your CI/CD pipeline.
- What are deployment slots in Azure App Service, and how can you use them with Azure DevOps?
- Deployment slots allow deploying different versions of an application to separate environments in Azure App Service. Azure DevOps release pipelines can automate swapping or testing of these slots.
