IntroductionCurious about how to ace your Azure DevOps Engineer interview?Stay tuned as we'll uncover some of the top and expert-reviewed interview questions you need to prepare before stepping up your DevOps career!Microsoft Azure is a leading cloud service provider. As its use grows, so does the need for Azure professionals. DevOps Engineer roles are in high demand. You're at the right place if you’re looking to step up your DevOps career and enhance your designation. List of Azure DevOps Interview Questions for Experienced CandidatesAs we’ll talk about interview questions for professional candidates, we assume you already have a solid grasp of basic concepts and tools for Azure DevOps. Here are some key questions to help you prepare for an interview:What are break-fix issues in Azure DevOps?These issues occur when something starts working abnormally in the system. Thus, break-fix issues need immediate actions and quick resolutions to restore normal operations. What's the difference between Azure DevOps Services and Azure DevOps Server?When we say Azure DevOps Services, we’re talking about the cloud-based services provided and managed by Microsoft. When we say Azure DevOps server, we talk about self-hosted servers on the company's infrastructures that give them more control. Define VNetA VNet, or Virtual Network, is a tool in Azure that helps create an isolated network in the cloud. It ensures that the resources you launch are separated from everything else. It's like having a private network in the cloud where only your specific resources can communicate with each other.What is the purpose of Microsoft Entra ID?Firstly, I’d like to mention that it was previously called ‘Azure Active Directory’ (Azure AD). It’s a security solution that protects a company with cloud identity and access management. It ensures secure connection of customers, employees, and partners with devices, apps, and other crucial data. What does Azure service fabric do?Azure service fabric simplifies the build and deployment of microservices-based applications. (As an experienced individual, you must have already known that microservices-based apps evolved from monolithic apps!) This solution handles both stateful and stateless operations. Also, it runs on Windows and Linux, making it portable across various cloud environments like AWS, OpenStack, and VMware.What are fault domains in Azure?Fault domains are groups of virtual machines that share the same power source and network. They help reduce the impact of hardware failures or power outages. Azure automatically spreads VMs across different fault domains to increase reliability.What is the Dogpile effect, and how can you prevent it?The Dogpile effect occurs when a cache expires and multiple requests for the same data hit your system simultaneously. This can overwhelm your database or service, causing slowdowns or crashes.When the cache expires and the first request comes in, lock the cache key. This prevents other requests from querying the database until the cache is updated and the lock is released. This way, only one request refreshes the cache, and the others wait, reducing the load on your system.Why use Azure Pipelines, Continuous Integration, and Continuous Deployment together?The use of Azure Pipelines with Continuous Integration (CI) and Continuous Deployment (CD) ensures better code quality and smooth automation. It also speeds up the process by integrating development and connecting with GitHub automatically.How do you manage secrets in Azure DevOps?The best way to protect a secret is to avoid needing one. First, review your Azure pipeline to see if alternatives to using secrets are available. If secrets are necessary, use secret variables and manage them with Azure Key Vault. Avoid treating structured data as secrets, and regularly review source code and run logs for secure handling.What is DevOps Toolchain?The DevOps Toolchain is a set of tools used to manage all phases of DevOps, from planning to monitoring. It automates essential operations like deployment and testing. While simple tasks can be done manually, automation becomes crucial as tasks and complexity grow.What is Blue-Green Deployment, and how is it used in Azure DevOps?Blue-Green Deployment involves two identical environments, Blue and Green. One handles live traffic while the new version is deployed to the other. After testing, traffic switches to the new environment. This setup in Azure DevOps makes updates smoother and allows for quick rollbacks if needed.What happens if you exceed the maximum authentication attempts in Azure?If you exceed the maximum authentication attempts, Azure provides advanced account recovery options. You can use methods like verifying IP addresses, resetting passwords, or using two-step authentication to regain access to your account.What is Azure Redis Cache?Azure Redis Cache is a managed version of the popular open-source Redis cache. It speeds up applications by caching data and integrates securely with Azure apps. It supports data structures like hashes and sets, providing efficient and structured data management.Practical Azure DevOps Interview Scenario QuestionsHow would you migrate a medium-large project from Azure DevOps Server to Azure DevOps Service?I’d use the Azure DevOps Migration Tool. It automates the transfer of source code, test cases, work items, and more. The tool also helps identify potential issues and offers recommendations for a smooth migration.For a highly confidential financial company, which Azure DevOps solution would you choose and why?I’d choose Azure DevOps Server. It’s an on-premises solution, keeping all data within the company’s network, which enhances security and confidentiality for sensitive financial information.Would you recommend Microsoft-hosted or self-hosted agents for Azure Pipelines, considering specific software needs and performance?I’d recommend self-hosted agents. They let you install the exact software and tools needed for your project and offer better performance, especially for complex builds. This gives you more control and can lead to faster build times compared to Microsoft-hosted agents.How would you manage dependencies in a complex microservices architecture using Azure DevOps?I'd use Azure Artifacts to manage and share packages, implement semantic versioning for updates, and run automated integration tests in CI/CD pipelines to catch issues early. Defining clear API contracts between microservices and using tools like Dependabot or Renovate for automatic updates also helps manage dependencies effectively.ConclusionThese interview questions will prepare you for various aspects of Azure DevOps. They cover core concepts, tools, and specific scenarios. Take it as a great opportunity and a learning blog to test your knowledge and problem-solving skills across different situations.Read Morehttps://devopsden.io/article/kpi-for-devopsFollow us onhttps://www.linkedin.com/company/devopsden/
