Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
namespace
Why it's wrong here
Namespace is optional in metadata for namespaced Roles, and invalid for cluster-scoped ClusterRoles, making it not universally required.
- ✓
apiVersion
Why this is correct
Every Kubernetes resource manifest requires apiVersion.
- ✗
subjects
Why it's wrong here
Subjects belong to RoleBindings and ClusterRoleBindings, not Roles or ClusterRoles.
- ✓
rules
Why this is correct
The rules block defining API groups, resources, and verbs is mandatory for authorization roles.
- ✓
kind
Why this is correct
The kind field ('Role' or 'ClusterRole') is mandatory.
