AAll file uploading method provided by Alibaba Cloud OSS service will support resuming from break point.

BIf you are uploading some small files (<1m), you can choose using put method to be able finish uploading in one http request.

CIf you are using OSS to store some log files which are continuously being updated, you better choose
streaming method to be able to append to one existing object instead of overwriting.

DIf you need to upload very large file you better use multi-part uploading to get the capability of resuming from break point.

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.

C seems a bit off to me. Can you really append with streaming?

Multi-part uploading sounds right for large files, but I wonder if there's a limit on file size for the put method too.

I feel like streaming for log files makes sense, but I can't recall if it really allows appending without overwriting.

I remember practicing a question about file sizes and upload methods, and I think the put method is indeed for small files.

I think option A might be the one that's not correct, but I'm not entirely sure if all methods really support resuming.

Resuming from a breakpoint is important for large file uploads, so I'll pay close attention to that aspect in the options.

The key is to understand the use cases for each method and match them to the scenario described. I'll need to read the options closely.

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.
