Multiple Choice

A Solutions Architect is building an online shopping application where users will be able to browse items, add items to a cart, and purchase the items.

Occasionally, during testing, item images deleted from the S3 bucket are still visible to some users. What is a flaw in this design approach?

• A) Defining S3 buckets by item may cause partition distribution errors, which will impact performance.
• B) Amazon S3 DELETE requests are eventually consistent, which may cause other users to view items that have already been purchased
• C) Amazon S3 DELETE requests apply a lock to the S3 bucket during the operation, causing other users to be blocked
• D) Using Amazon S3 for persistence exposes the application to a single point of failure
