Question

A company is storing backup files by using Amazon S3 Standard storage. The files are accessed frequently for 1 month. However, the files are not accessed after 1 month. The company must keep the files indefinitely. Which storage solution will meet these requirements MOST cost-effectively?

Accepted Answer

Correct answer: B. Correct: B. Files are hot for one month, then never accessed but kept forever, so a lifecycle rule transitioning to Glacier Deep Archive after 30 days gives the lowest long-term cost. C (Standard-IA) and D (One Zone-IA) cost far more than Deep Archive for indefinite retention. A (Intelligent-Tiering) suits unpredictable access, but here the pattern is known — cold after a month — so Deep Archive is cheaper.
