What is a key benefit of using Kubernetes Namespaces?

• A. Isolating resources and limiting the scope of user privileges
• B. Increasing cluster resource quotas
• C. Providing a separate node pool
• D. Managing node labels

Answer: (B)

Namespaces create virtual boundaries inside a Kubernetes cluster, allowing you to isolate resources for different teams or projects and to limit what users or service accounts can do within each boundary. By organizing workloads into separate namespaces, you prevent one group’s resources from interfering with another and enforce security and usage controls through RBAC and ResourceQuotas scoped to that namespace. This isolation and restricted access is the primary benefit of using namespaces. They do not inherently increase the overall cluster capacity, and they aren’t about creating separate node pools or manipulating node labels, which are scheduling and node-management concerns handled outside of namespace boundaries.
