Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Role
A Role defines permissions within a specific namespace, whereas a ClusterRole defines cluster-scoped permissions. Since the requirement is restricted to the 'development' namespace, a Role is the correct resource.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SecurityContextConstraints
Why it's wrong here
SecurityContextConstraints is an OpenShift-specific resource, not standard Kubernetes RBAC.
- ✓
Role
Why this is correct
Role is used to define permissions within a single namespace.
- ✗
PodSecurityPolicy
Why it's wrong here
PodSecurityPolicy was used for security hardening and has been deprecated/removed, not for RBAC permissions.

ClusterRole is used for cluster-scoped resources or cross-namespace permissions.
