1Z0-1072-25 Question 245
Single answerYou manage a daily 500 GB backup process to Oracle Cloud Infrastructure (OCI) Object Storage. Recently, some parts of your uploads have been failing due to intermittent network issues, forcing you to re-upload a significant portion of the data each time. You want to minimize network overhead and processing time when failures occur. Which approach should you implement to handle partial failures effectively?
- A
Use an Archive Storage bucket to automatically fix partial uploads and avoid having to restart.
- B
Implement the multipart upload process with a moderate part size, then re-upload only failed parts when interruptions occur.
- C
Configure auto-tiering so partially uploaded objects are completed automatically in Standard Object Storage.
- D
Use a single-file upload approach from the CLI and rerun the full upload if it fails at any stage.
Show answer and explanation
Correct answer: B
Explanation
Oracle Cloud Infrastructure Object Storage supports multipart uploads, allowing you to upload large files efficiently by splitting them into parts. If some parts fail due to network issues, you only need to re-upload those specific parts, avoiding the need to restart the entire upload. This approach is documented in the OCI Object Storage guide (https://docs.oracle.com/en-us/iaas/Content/Object/Tasks/usingmultipartuploads.htm) and is a best practice for large file transfers that may experience intermittent failures.
- A. Incorrect.
Option 1 is incorrect. Archive Storage is not designed to "fix" partial uploads automatically. Archive Storage is intended for long-term data retention and requires objects to be stored in cold storage, not for reducing partial upload failures in real-time.
- B. Correct.
Option 2 is correct. When using OCI Object Storage multipart uploads, you can choose a moderate part size and re-upload only the chunks that fail. This reduces overhead since you don�t have to re-upload successful parts, providing a reliable way to handle intermittent failures.
- C. Incorrect.
Option 3 is incorrect. Auto-tiering moves data across storage tiers based on policies and doesn't resolve partial upload failures. It won�t automatically complete or fix stalled multipart uploads.
- D. Incorrect.
Option 4 is incorrect. A single-file upload approach will force you to restart the entire upload if there is a failure, which is inefficient for large files and doesn�t take advantage of multipart upload resilience.
