Assertion (A): The cheapest storage class is not always the cheapest overall.
Reason (R): Retrieval charges and minimum durations can exceed the saving on storage.

  • A.A is true but R is false
  • B.A is false but R is true
  • C.Both A and R are true, and R is the correct explanation of A
  • D.Both A and R are true, but R is not the correct explanation of A

Answer: C

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason names the two charges that catch people out. Archive classes bill for retrieval, sometimes substantially, and impose a minimum storage duration so that an object deleted early is billed as though it had stayed. Data read or churned frequently can therefore cost more in an archive class than in a standard one, which is why lifecycle rules must be set from the actual access pattern.
