AWS Certified Solutions Architect – Professional — Question 82

When you put objects in Amazon S3, what is the indication that an object was successfully stored?

Answer options

• A. A HTTP 200 result code and MD5 checksum, taken together, indicate that the operation was successful.
• B. Amazon S3 is engineered for 99.999999999% durability. Therefore there is no need to confirm that data was inserted.
• C. A success code is inserted into the S3 object metadata.
• D. Each S3 account has a special bucket named _s3_logs. Success codes are written to this bucket with a timestamp and checksum.

Correct answer: A

Explanation

The correct answer is A because receiving a HTTP 200 status code and MD5 checksum confirms that the object was uploaded successfully. Option B is incorrect as durability does not negate the need for confirmation. Option C is wrong because success codes are not stored in the object metadata. Option D is also incorrect since there is no special bucket for logging success codes.
