What is the purpose of a Namespace in Kubernetes?

• A. To store container images
• B. To manage network policies
• C. To provide a scope for names and divide cluster resources between multiple users
• D. To configure storage classes

Answer: (C)

Namespaces provide a scope for resource names and divide cluster resources between multiple users or teams. This means resources with the same name can exist in different namespaces without colliding, enabling logical separation within a single cluster. They also allow applying per-namespace RBAC and quotas, which helps govern access and resource usage for separate projects or tenants. This organizational and isolation function is what makes namespaces useful in multi-tenant scenarios. Storing container images happens in registries, not namespaces; storage classes govern volume provisioning at the cluster level, and while network policies can be defined per namespace, the primary purpose of a namespace is not to manage networking or storage.
