Kubernetes - Production Best Practices

ABecause RBAC settings automatically sync across clusters

BBecause each cluster has its own API server and security context

CBecause RBAC is only needed on the primary cluster

DBecause RBAC is deprecated in multi-cluster setups

Step-by-Step Solution

Solution:

Step 1: Understand RBAC scope
RBAC controls access per cluster since each has its own API server and security model.
Step 2: Explain why separate configuration is needed
Settings do not sync automatically; each cluster requires its own RBAC setup for security.
Final Answer:
Because each cluster has its own API server and security context -> Option B
Quick Check:
RBAC is cluster-specific due to separate API servers [OK]

Quick Trick: Configure RBAC per cluster for proper security [OK]
