CKA study material · question 836 of 1000

Before deleting a claim in front of a production database, an operator wants to be sure the data survives. What should they change first?

  1. The claim's access mode to ReadOnlyMany
  2. The StorageClass's volumeBindingMode
  3. The claim's storageClassName to the empty string
  4. The bound PersistentVolume's reclaim policy to Retain
Show the answer

Answer: D. The bound PersistentVolume's reclaim policy to Retain

Patching persistentVolumeReclaimPolicy to Retain on the bound volume stops the storage being deleted with the claim; changing the class afterwards would not help an already-bound volume.
