A company wants an Amazon S3 solution that provides access to object storage within single- digit milliseconds. Which solution will meet these requirements?

Question

Options

• AS3 Express One Zone
• BS3 Standard
• CS3 Glacier Flexible Retrieval
• DS3 Glacier Instant Retrieval

• A
  5% (2)
• B
  89% (33)
• C
  3% (1)
• D
  3% (1)

Explanation

Explanation

S3 Standard is the correct answer because it is designed for frequently accessed data and delivers consistent, low-latency performance in the single-digit milliseconds range - exactly what the question requires. It is the default, general-purpose storage class optimized for high availability and immediate data access.

Why the distractors are wrong:

• S3 Express One Zone (A) actually provides even faster performance (single-digit milliseconds too, but at a higher cost and with reduced availability in one AZ) - however, it is a newer, specialized class not typically the go-to answer for standard millisecond access requirements
• S3 Glacier Flexible Retrieval (C) is designed for archival storage with retrieval times ranging from minutes to hours - far too slow
• S3 Glacier Instant Retrieval (D) does offer millisecond access but is intended for infrequently accessed archival data and comes at a higher retrieval cost, making it not the best fit for general object storage needs

Memory Tip: Think of "Standard = Standard speed" - if a question simply asks for reliable millisecond object storage without mentioning archiving or infrequent access, S3 Standard is your default answer. Reserve Glacier options for archival use cases.
