In VMware vSphere with Supervisor (used within VCF), a vSphere Namespace allows administrators to define resource quotas for Kubernetes workloads.
The vSphere documentation specifies that administrators can configure limits on:
CPU resources
Memory resources
Storage capacity
These quotas control the maximum resources that workloads deployed within the namespace can consume.
Incorrect options:
The number of containers (A) is managed at the Kubernetes level, not directly as a namespace resource quota in vSphere.
The number of services (D) is a Kubernetes object count limit, not a vSphere namespace resource limit.
Thus, the three configurable resource limitations are CPU, Memory, and Storage.
