1Z0-1072-25 Question 241
Select 2Your data analytics team needs to upload a 500 GB data set from an on-premises data center to an Oracle Cloud Infrastructure (OCI) Object Storage bucket. They want to configure multi-part uploads for faster and more reliable transfer using the OCI CLI. Which TWO steps must you take to properly configure and optimize multi-part uploads with the OCI CLI?
- A
Set the '--parallel-upload-count' parameter when using 'oci os object put' to specify concurrency.
- B
Use a policy to enforce data tiering before beginning the multi-part upload.
- C
Provide a custom part size using the '--part-size' parameter when running 'oci os object put'.
- D
Enable encryption-in-transit before starting a multi-part upload to reduce part size overhead.
- E
Extend the time-to-live (TTL) for the token by enabling instance principal advanced settings.
Show answer and explanation
Correct answers: A, C
Explanation
When uploading very large files to OCI Object Storage, multi-part uploads improve speed and reliability by splitting data into parallel parts. Using the OCI CLI, you typically set '--parallel-upload-count' to manage concurrency and '--part-size' to control individual chunk size. These settings reduce overall upload time and manage local system resource usage effectively. For detailed guidance, refer to the Oracle Cloud Infrastructure documentation on 'Using Multipart Upload to Upload an Object' in the OCI Object Storage Developer Guide.
- A. Correct.
Option 1: Correct. Setting '--parallel-upload-count' determines how many parts are uploaded simultaneously, helping optimize speed and bandwidth usage.
- B. Incorrect.
Option 2: Incorrect. While IAM policies are crucial for securing and managing access, they do not directly configure or optimize multi-part uploads. Data tiering is also unrelated to multi-part configuration steps in OCI.
- C. Correct.
Option 3: Correct. Specifying a '--part-size' value (for example, 128 MB) helps control memory usage and ensures that each chunk is sized appropriately for your environment, optimizing performance.
- D. Incorrect.
Option 4: Incorrect. Encryption-in-transit (HTTPS/TLS) is typically enabled by default for OCI services. While security is important, enabling it does not reduce multi-part upload overhead or part sizes directly.
- E. Incorrect.
Option 5: Incorrect. Extending time-to-live for tokens can help in long-running sessions but is not a required step for configuring multi-part uploads. Multi-part uploads rely primarily on concurrency and part-size parameters.
