CKA study material · question 834 of 1000

A Pod requiring a new attached volume stays Pending on an otherwise idle node with plenty of CPU and memory. What limit could explain it?

  1. The node's maximum number of attached volumes
  2. The namespace's PersistentVolumeClaim count quota
  3. The StorageClass's allowVolumeExpansion setting
  4. The volume's access mode
Show the answer

Answer: A. The node's maximum number of attached volumes

Nodes have a ceiling on simultaneously attached volumes, and the scheduler counts against it so a Pod is not placed where its volume could never attach.
