AWS Certified SysOps Administrator – Associate — Question 369

A company is uploading important files as objects to Amazon S3. The company needs to be informed if an object is corrupted during the upload.

What should a SysOps administrator do to meet this requirement?

Answer options

• A. Pass the Content-Disposition value as a request body during the object upload
• B. Pass the Content-MD5 value as a request header during the object upload
• C. Pass x-amz-object-lock-mode as a request header during the object upload
• D. Pass x-amz-server-side-encryption-customer-algorithm as a request body during the object upload

Correct answer: B

Explanation

Providing the Content-MD5 header during an Amazon S3 upload forces Amazon S3 to calculate the MD5 hash of the received object and compare it to the provided value, failing the upload if a mismatch occurs. The other options, such as Content-Disposition, Object Lock, and SSE-C parameters, do not provide data integrity verification during transit.
