Show Suggested Answer

Suggested Answer: A

Alibaba Cloud OSS service provides different methods for file uploading, such as simple upload, multipart upload, append upload, and resumable upload1. However, not all of these methods support resuming from break point, which is a feature that allows you to resume an interrupted upload from where it left off.The only method that supports resuming from break point is resumable upload, which is based on multipart upload and uses a checkpoint file to record the upload progress2. The other methods do not support resuming from break point, and will either overwrite or append to the existing object if the upload is interrupted and retried.

Option B is the right answer. For small files, the put method is the best choice to finish the upload in a single HTTP request.

I think option C is not correct. The streaming method is for appending data to an existing object, not for uploading new files.
