Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The MachineConfigPool resource named 'worker'.
Why it's wrong here
MachineConfigPools handle OS configurations, while pull secrets are managed via openshift-config/pull-secret and propagated by the MCO.
- ✗
The ClusterVersion custom resource spec field 'pullSecret'.
Why it's wrong here
ClusterVersion does not store pull secrets directly in its spec.
- ✓
A Secret named 'pull-secret' in the 'openshift-config' namespace.
Why this is correct
The cluster global pull secret is located in openshift-config/pull-secret.
- ✗
A ConfigMap named 'global-pull-registry' in 'kube-system'.
Why it's wrong here
Pull secrets are stored as Secrets in openshift-config, not ConfigMaps in kube-system.
