AWS Certified Developer Associate Practice Test 5

Correct answers - "Updating an existing object & Deleting an existing object" : Amazon S3 provides read-after-write consistency for PUTS of new objects in your S3 bucket in all regions with one caveat. The caveat is that if you make a HEAD or GET request to the key name (to find if the object exists) before creating the object, Amazon S3 provides eventual consistency for read-after-write.

Incorrect:

"Creating a new object" - For new objects it uses read-after-write consistency

"Reading an existing object" - Reading an existing object won't change the consistency of that object. Eventual consistency behaviour is observed when an object is read after it has been updated, or deleted, but the eventual consistency behaviour comes from the fact that object has been updated or deleted, not from the read action.
