Which feature allows categorisation and organisation of resources to help manage costs?

• A. Labels
• B. Taints
• C. Annotations
• D. Finalizers

Answer: (A)

Labels are the way to tag Kubernetes objects with meaningful, queryable metadata. By attaching simple key-value pairs like env=prod, app=web, or cost-center=ACME-123, you can categorize and group resources across namespaces and clusters. This makes cost management practical: tools and cloud providers can summarize and report usage by label, letting you see spend by environment, project, department, or cost center. Controllers and tooling also rely on labels to select and operate on related resources, enabling consistent organization without altering the objects’ core configuration. Taints influence scheduling decisions and don’t provide a way to categorize or group resources for cost reporting. Annotations store metadata but aren’t intended for querying or grouping, so they’re not as useful for cost allocation. Finalizers control deletion behavior and lifecycle, not organization or cost tracking.
