Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
All MachineConfigPools must be fully updated and not in a degraded state.
Why this is correct
Degraded node pools can prevent rolling out cluster-wide payload updates.
- ✗
The cluster must be switched to the 'nightly' channel for all production upgrades.
Why it's wrong here
Production upgrades use stable or fast channels, not nightly.
- ✗
All user-created namespaces must be temporarily deleted prior to upgrade.
Why it's wrong here
Deleting user namespaces is unnecessary and destructive.
- ✓
The target version must be part of a valid, recommended update path from the current version.
Why this is correct
The CVO enforces valid upgrade paths defined by Red Hat graph data.
- ✓
All core cluster operators must report healthy status without being degraded.
Why this is correct
Degraded operators will block or fail cluster upgrades.
