CV0-004 Practice Question: A Kubernetes StatefulSet is deployed to run a…
A Kubernetes StatefulSet is deployed to run a database. The pods are stuck in pending state. The administrator checks and finds that the PersistentVolumeClaim is not bound to any PersistentVolume. Which of the following is the MOST likely cause?
⚠ Common exam trap
CompTIA often tests the distinction between a PVC being unbound due to no matching PV versus a PV being already bound, leading candidates to incorrectly select access mode or size mismatches when the real issue is PV exhaustion.
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
✓
The PV is already bound to another PVC.
When a PersistentVolumeClaim (PVC) remains unbound, the most common cause is that no PersistentVolume (PV) matches its requirements. If a PV is already bound to another PVC, it cannot be reused unless released and reclaimed. This leaves the PVC in a pending state, preventing the StatefulSet pods from starting.
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 PVC and PV have different access modes.
Why it's wrong here
Access mode mismatch would prevent binding, but the error message would mention access mode incompatibility.
- ✓
The PV is already bound to another PVC.
Why this is correct
If the PV is already claimed, the new PVC cannot bind, leaving it unbound. This is a common scenario.
- ✗
The PVC requests storage size that exceeds available PV capacity.
Why it's wrong here
Size mismatch can cause binding failure, but the error would typically indicate the size exceeds available PVs.
- ✗
The storage class provisioner is not installed.
Why it's wrong here
If the provisioner were missing, the PVC would remain pending with a different error message, but the exhibit shows no bound PV, not a provisioning failure.
