Kubernetes MCQs – Kubernetes CI/CD Integration

Kubernetes CI/CD integration is essential for modern DevOps workflows, allowing automated build, test, and deployment processes across scalable environments. Tools like Jenkins, GitLab CI, Argo CD, and Tekton are commonly used to streamline the delivery pipeline within Kubernetes clusters.

This set of Multiple Choice Questions (MCQs) covers foundational to advanced CI/CD practices in Kubernetes, including YAML pipelines, GitOps workflows, and common command-line operations. These MCQs are ideal for preparing for technical interviews, certification exams, or improving your real-world CI/CD implementation skills.
