Imagine you have created an S3 storage bucket named my-storage-bucket. The bucket has two inner folders, named folder1 and folder2, containing in turn two subfolders each, named subfolder1 and subfolder2. You have registered the bucket as an object store secret in SAP AI Core, with path prefix folder1. Where should you store your training data for SAP AI Core to be able to access it?

Choose the correct answer.

In my-storage-bucket/folder1 or any of its subfolders

In my-storage-bucket/folder1 only

Anywhere in my-storage-bucket

Either in my-storage-bucket/folder1/subfolder1 or my-storage-bucket/folder1/subfolder2
