1Z0-1072-25 Question 242
Select 2Your organization needs to upload a large 500 GB dataset from on-premises to Oracle Cloud Infrastructure (OCI) Object Storage. The network connection is occasionally unreliable, so you decide to configure multipart uploads to minimize data re-transfer. Which two actions will enable you to reliably resume an incomplete upload if the connection is lost?
- A
A. Keep track of the unique upload ID used for each multipart upload session
- B
B. Enable automatic versioning in the Object Storage bucket to lock each part upon upload
- C
C. Use the same part size for each file part and upload them using the same upload ID
- D
D. Configure a signed URL to automatically retry parts without specifying an upload ID
Show answer and explanation
Correct answers: A, C
Explanation
In OCI, multipart uploads use a unique upload ID to track each chunk of a file. If the upload is interrupted, you can resume by referencing the same upload ID and only transferring the missing parts. Maintaining a consistent part size ensures that previously uploaded parts are not re-transferred. Refer to the OCI documentation on Object Storage multipart uploads for detailed steps on how to configure and resume large file transfers.
- A. Correct.
A. Correct. When configuring multipart uploads, tracking the unique upload ID is crucial. If the connection is lost, using the same upload ID lets you resume uploading remaining parts without re-uploading the entire file.
- B. Incorrect.
B. Incorrect. Object Storage versioning helps maintain file history but does not directly manage or resume incomplete multipart uploads. It does not prevent re-upload of partially completed parts.
- C. Correct.
C. Correct. Using consistent part sizes under a single upload ID helps OCI identify which parts are complete. This ensures that any remaining parts can be uploaded without affecting parts that have already been successfully transferred.
- D. Incorrect.
D. Incorrect. A signed URL can be used for temporary access to an object in a bucket, but it does not inherently handle multipart upload management or let you resume automatically. You must still specify the upload ID to resume an interrupted upload.
