1Z0-1072-25 Question 246
Select 3Your team is uploading a 250 GB data file to an Oracle Cloud Infrastructure (OCI) Object Storage bucket. You want to minimize re-transfer in the event of a network interruption and ensure the final file is properly finalized in the bucket. Which three statements are correct about configuring a multi-part upload in OCI to meet these requirements?
- A
Each part in a multi-part upload must be at least 10 MB in size (except for the last part).
- B
If any part fails during upload, you must restart the entire multi-part upload from scratch.
- C
You can track and resume an incomplete multi-part upload by referencing the upload ID.
- D
Multi-part uploads must be performed in a strictly sequential manner; concurrency is not supported.
- E
You must explicitly commit the multi-part upload after successfully uploading all parts.
Show answer and explanation
Correct answers: A, C, E
Explanation
Multi-part uploads in OCI Object Storage help efficiently and reliably transfer very large files. You define the part size and can upload multiple parts in parallel. If a part fails, you can retry only that part instead of restarting. Once all parts are uploaded, you must commit the multi-part upload to assemble the parts into a single object. Refer to OCI documentation on Object Storage multi-part uploads for best practices on part size, concurrency, and managing upload IDs.
- A. Correct.
Correct. OCI enforces a minimum part size of 10 MB for multi-part uploads (except the last part). This ensures efficient handling of large objects and reduces overhead.
- B. Incorrect.
Incorrect. OCI allows you to retry the failed part without restarting the entire multi-part upload, preventing wasted bandwidth and time.
- C. Correct.
Correct. When you initiate a multi-part upload, OCI provides an upload ID. You can use this ID to resume or manage the upload if any part fails or if there is an interruption.
- D. Incorrect.
Incorrect. OCI supports concurrent multi-part uploads, which helps speed up large file transfers by uploading parts in parallel.
- E. Correct.
Correct. Even after all parts are uploaded, the final step is to explicitly commit the upload, ensuring OCI compiles all parts into the final object in your bucket.
