1Z0-1072-26 Compute Practice Question
You are running a stateful application inside an OKE cluster that requires persistent storage backed by OCI Block Volumes. When a pod is rescheduled to a different worker node due to a node failure, how does the Persistent Volume (PV) behave?
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 OCI Block Volume CSI driver automatically detaches the volume from the old node and attaches it to the new worker node.
OCI Block Volume CSI (Container Storage Interface) driver dynamically detaches the block volume from the failed worker node and attaches it to the new worker node where the rescheduled pod is running, preserving data persistence.
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 OCI Block Volume CSI driver automatically detaches the volume from the old node and attaches it to the new worker node.
Why this is correct
The CSI driver manages volume attachment lifecycle across nodes during pod rescheduling.
- ✗
You must manually log into the OCI Console, detach the volume, and attach it to the new worker node.
Why it's wrong here
The process is automated by the OCI Block Volume CSI plugin in Kubernetes.
- ✗
The persistent volume is converted to Object Storage automatically.
Why it's wrong here
Persistent volumes remain block volumes.
- ✗
The data is permanently lost because block volumes cannot move across worker nodes.
Why it's wrong here
Block volumes persist independently of worker nodes.
