  2. A revision is created only when the Pod template changes
  3. A rollback restores the Pod template, not the replica count
  4. A rollback restores the replica count as well
Show the answer

Answer: B. A revision is created only when the Pod template changes
C. A rollback restores the Pod template, not the replica count

Scaling never produces a revision, so rolling back restores only the Pod template part.
