KCNA Cloud Native Application Delivery Practice Question
A company is adopting a GitOps workflow for their Kubernetes deployments. They want to ensure that the cluster state always matches the desired state defined in a Git repository. Which tool is specifically designed for this purpose?
⚠ Common exam trap
A common mix-up: candidates confuse Helm or Kustomize as GitOps tools because they are used in GitOps pipelines, but they lack the continuous reconciliation and drift detection that a dedicated GitOps operator like Argo CD provides.
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
✓
Argo CD
Argo CD is a declarative, GitOps continuous delivery tool specifically designed for Kubernetes that automatically synchronizes the live cluster state with the desired state defined in a Git repository. It continuously monitors the cluster and Git, applying any drift to ensure the cluster matches the repository, which is the core requirement of a GitOps workflow.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Helm
Why it's wrong here
Helm is a package manager for Kubernetes, not a GitOps operator.
- ✓
Argo CD
Why this is correct
Argo CD is a GitOps tool that syncs cluster state with a Git repository.
- ✗
Kustomize
Why it's wrong here
Kustomize is for customizing Kubernetes manifests, not for continuous sync.
- ✗
Prometheus
Why it's wrong here
Prometheus is a monitoring system, not a GitOps tool.
