Which Kubernetes concept enables grouping and selecting resources for management tasks and cost tracking?

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

Answer: (B)

Grouping and selecting resources for management tasks and cost tracking is achieved with labels. A label is a simple key-value pair attached to Kubernetes objects like pods, deployments, services, and nodes. By tagging related resources with the same labels, you create a logical collection that you can target with label selectors in commands and controllers. This makes it possible to perform operations only on that subset (for example, upgrading or scaling all resources belonging to a specific app or environment) and to attribute usage for cost tracking to those same groups. Tools used for cost management and governance often rely on these labels to map resource usage to workloads. Annotations carry metadata but aren’t used for selecting resources, while taints influence scheduling rules on nodes, and finalizers manage cleanup during deletion.
