AWS Certified Cloud Practitioner (CLF-C02) — Question 493

A company wants an Amazon S3 solution that provides access to object storage within single-digit milliseconds.

Which solution will meet these requirements?

Answer options

• A. S3 Express One Zone
• B. S3 Standard
• C. S3 Glacier Flexible Retrieval
• D. S3 Glacier Instant Retrieval

Correct answer: A

Explanation

S3 Express One Zone is a high-performance, single-zone storage class explicitly designed to deliver consistent, single-digit millisecond data access for the most latency-sensitive applications. While S3 Standard offers low latency, it is typically in the double-digit milliseconds, and the S3 Glacier options are intended for archival storage with much longer retrieval times.
