Top 10 DevOps Coding Questions

Below is a list of the top coding questions that have emerged in 2026. Understanding these questions will equip you with the knowledge and confidence needed to excel in your DevOps endeavors.

1. What is Infrastructure as Code (IaC) and why is it important?

Infrastructure as Code (IaC) is a vital DevOps practice that involves managing and provisioning computing infrastructure through machine-readable definition files, rather than physical hardware configuration. IaC:- Promotes consistency- Reduces deployment time and manual errors- Facilitates infrastructure versioning

2. How does Continuous Integration (CI) differ from Continuous Deployment (CD)?

CI/CD are foundational practices in DevOps:- Continuous Integration involves automatically integrating code changes into a shared repository multiple times a day, allowing for immediate testing and detection of issues.- Continuous Deployment goes a step further by automatically releasing every code change to production, ensuring fast feedback cycles and minimizing human intervention.

3. Explain Blue/Green Deployment.

Blue/Green Deployment is a strategy designed to minimize downtime and risks associated with deploying new software versions. This approach involves maintaining two identical environments:- Blue Environment: Current production- Green Environment: New version awaiting deployment

Switching traffic from the blue environment to the green environment ensures a seamless upgrade process.

4. What role do containers play in DevOps?

Containers are lightweight, portable units that bundle an application along with its dependencies. They offer:- Uniform environments across development, testing, and production- Improved resource utilization- Simplified management with tools like Kubernetes

5. How can you enhance security in DevOps pipelines?

Security is a cornerstone of DevOps, often referred to as DevSecOps. Key practices include:- Implementing automated security testing- Utilizing secret management tools for sensitive data- Ensuring compliance through continuous monitoring

6. What is Azure DevOps and how does it integrate with PowerShell?

Azure DevOps offers a suite of tools for DevOps practices. It seamlessly integrates with PowerShell in Azure DevOps pipelines, enabling automation of infrastructure and services on the Azure cloud.

7. Describe the importance of logging and monitoring in DevOps.

Logging and monitoring ensure that applications are running as expected and help identify and resolve issues efficiently. They provide:- Real-time insights into application performance- Alert systems for unusual behavior- Data-driven decision making

8. How does version control support DevOps practices?

Version control systems, such as Git, are critical for DevOps as they:- Enable collaboration by tracking changes- Help in retrieving previous versions of code- Facilitate branch management for feature development

9. What are microservices and how do they relate to DevOps?

Microservices architecture involves building applications as a collection of small, independent services. DevOps practices support microservices by:- Streamlining code deployment- Enabling scalable, resilient infrastructure- Facilitating rapid iterations

10. Explain how agile development supports the principles of DevOps.

Agile development emphasizes adaptive planning, early delivery, and continuous improvement. It aligns with DevOps by:- Encouraging cross-functional teams- Prioritizing customer feedback and iterative progress- Supporting rapid delivery cycles
