1Z0-1072-25 Question 244
Single answerYour data analytics team needs to upload a 100GB dataset to an OCI Object Storage bucket. They want to configure and use a multipart upload to increase reliability and performance. If one of the parts fails during the upload due to a network interruption, which statement correctly describes how OCI handles this situation?
- A
You must restart the entire multipart upload from the beginning and cannot salvage previously uploaded parts.
- B
You can delete the failed part and re-upload just that part without affecting successfully uploaded parts.
- C
You must finalize the upload despite the failed part; OCI automatically fills missing parts with zero data.
- D
You can only resume the upload if you choose identical part sizes for every part, including the last part.
Show answer and explanation
Correct answer: B
Explanation
When configuring multipart uploads in Oracle Cloud Infrastructure, you can retry only failed parts without restarting the entire upload. This is a key advantage for large files or unstable network conditions. For more details, refer to OCI Object Storage documentation on multipart uploads, which explains how re-uploading specific parts works and how to finalize the upload once all parts have been successfully transferred.
- A. Incorrect.
Incorrect: In OCI, you do not need to restart from scratch if a part fails. Successfully uploaded parts remain intact while only the failed part needs to be re-uploaded or replaced.
- B. Correct.
Correct: OCI� multipart upload feature allows you to re-upload only the parts that failed. Successfully transferred parts are retained, so you do not lose progress.
- C. Incorrect.
Incorrect: OCI does not fill missing parts with placeholder data. You must successfully upload each part and explicitly commit the multipart upload before it is finalized.
- D. Incorrect.
Incorrect: While choosing a consistent part size is recommended, the last part can be smaller. There's no requirement that all parts must be identical to enable resuming an upload.
