KCNA Container Orchestration Practice Question
A developer wants to run a containerized application locally for development. Which tool is most appropriate?
⚠ Common exam trap
A common mix-up: candidates confuse container runtimes (CRI-O, containerd) or orchestration platforms (Kubernetes) with development tools, assuming any container-related technology can run apps locally, but the KCNA exam specifically tests the understanding that Docker Compose is the standard for local multi-container development.

Correct answer & explanation
✓
Docker Compose
Docker Compose is the most appropriate tool for running a containerized application locally during development because it allows you to define and manage multi-container applications using a simple YAML file. It handles container lifecycle, networking, and volume mounts with a single `docker compose up` command, making it ideal for local development workflows where rapid iteration and simplicity are key.
