A resource quota in a Kubernetes environment defines the maximum amount of resources that can be allocated to a specific namespace. By setting these limits, Kubernetes helps manage the resources in the cluster more effectively and prevents any single namespace from monopolizing resources such as CPU, memory, and persistent storage.

Enforcing resource quotas is particularly important in multi-tenant clusters where different teams or applications share the same resources. It allows administrators to ensure fair usage and maintain overall cluster performance. When a resource quota is applied, Kubernetes tracks the usage across all resources within the namespace and enforces the defined limits when users attempt to create new resources or increase the existing ones.

This ensures that each team or application has the necessary resources to function while safeguarding against overconsumption that could degrade the performance for other workloads within the cluster. Therefore, the correct answer accurately captures the purpose of resource quotas in maintaining capacity limits within specific namespaces in a Kubernetes setup.
