An insurance firm needs to archive historical policy documents to meet compliance regulations. These files are rarely accessed, but when a customer requests a policy lookup, the document must be retrieved immediately (within milliseconds). The firm wants to minimize storage costs without sacrificing durability. Which Amazon S3 storage class should the firm choose?

  1. A
    Amazon S3 Standard
  2. Amazon S3 Standard-Infrequent AccessAnswer
  3. C
    Amazon S3 Glacier Flexible Retrieval
  4. D
    Amazon Elastic File System Infrequent Access

Answer

Amazon S3 Standard-Infrequent Access is the correct choice because it is designed for infrequently accessed data that requires rapid, millisecond retrieval when requested, providing the necessary durability and low latency at a lower storage cost than Amazon S3 Standard.
Amazon S3 Standard-Infrequent Access is the correct choice because it is specifically designed for data that is accessed less frequently but requires rapid, millisecond retrieval when requested. It provides the same durability and low latency as Amazon S3 Standard but at a lower storage cost, matching the requirements of the scenario.

Step-by-Step Solution

1
Analyze the access frequency and retrieval time requirements.
The documents are accessed infrequently but must be retrieved within milliseconds when requested.
This eliminates archive classes with minutes-to-hours retrieval times, such as Glacier Flexible Retrieval.
2
Compare the remaining storage options to find the most cost-effective solution.
Amazon S3 Standard-Infrequent Access offers the same durability and low latency as Amazon S3 Standard but at a lower storage cost, fitting the cost-optimization goal.
This provides the required millisecond performance while minimizing monthly storage fees.

Key Concept

Selecting S3 storage classes based on access frequency, retrieval speed requirements, and cost-efficiency.
