KCNA Cloud Native Application Delivery Practice Question
A platform team wants to package a multi-service application into a single distributable artifact that includes Kubernetes manifests, default configuration values, and a version number. Which tool is purpose-built for this task?
⚠ Common exam trap
The trap here is assuming any YAML management tool can package and version an application, when only Helm provides a chart format with built-in release versioning.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Helm
Helm is the package manager for Kubernetes: a chart bundles templated manifests, default values, and metadata into a versioned artifact that can be installed, upgraded, and rolled back as a unit. The other tools either patch existing YAML, talk to the API server, or target a different runtime entirely.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
kubectl
Why it's wrong here
kubectl is a CLI for interacting with the Kubernetes API server; it applies manifests but does not bundle them with default values or version metadata. There is no kubectl package format, so it cannot serve as the distributable artifact the team needs for shipping a multi-service application.
- ✗
Kustomize
Why it's wrong here
Kustomize overlays and patches existing YAML without templating, and it has no built-in packaging or versioning format. It is often used inside Helm or kubectl, but by itself it cannot produce a single distributable artifact with a chart version, so it does not satisfy the requirement of packaging the application.
- ✗
Docker Compose
Why it's wrong here
Docker Compose defines and runs multi-container applications on a single Docker host, not on Kubernetes. It uses a compose.yaml file that references images and runtime settings, but it does not generate Kubernetes manifests or provide chart versioning, so it is not the right packaging tool for this Kubernetes scenario.
- ✓
Helm
Why this is correct
Helm packages Kubernetes resources into a chart, a versioned archive containing templated manifests, a values.yaml file for defaults, and Chart.yaml metadata. Installing or upgrading the chart renders templates with supplied values and applies them to the cluster, giving the team a single distributable artifact with a semantic version.
