You need to upload a single 1 TB file from your data center into an S3 bucket using multipart upload. Which method should you use to perform the upload?

The aws s3 cp command automatically performs multipart uploads for large files, making it suitable for uploading a 1 TB file efficiently and reliably. It handles splitting the file into parts, uploading them concurrently, and reassembling them in S3. Using the S3 console is generally limited to smaller files (typically up to 160 GB) and would not be practical or supported for a 1 TB file. The s3api copy-object command is used to copy objects between S3 buckets or within the same bucket, not for uploading files from a local data center. The s3api put-object command can be used for single-part uploads or for initiating a multipart upload manually, but it requires more complex scripting to manage the individual parts, making s3 cp a simpler and more robust solution for large files.
