- A. To configure load balancing between services
- B. To specify how groups of pods are allowed to communicate with each other and other network endpoints
- C. To define how services are exposed outside the cluster
- D. To optimize network performance between nodes

**Answer:** To specify how groups of pods are allowed to communicate with each other and other network endpoints
