Store per-user directories in Cloud Storage and ensure an empty subdirectory exists when a user is created. What should you do?

Cloud Storage does not have true directories; it uses a flat namespace. However, it simulates directories by treating object names that contain a trailing slash ('/') as folder-like objects. Creating a zero-byte object with a name like users/user123/ effectively creates an empty "folder" for user123. This is the standard and recommended way to represent empty directories in Cloud Storage. The other options are incorrect because: Deleting an object inside a subdirectory doesn't create the subdirectory itself. Granting WRITER ACL permission is about access control, not directory creation. Setting Content-Type to CLOUDSTORAGEFOLDER is not a valid or recognized method for creating a virtual folder; Cloud Storage handles this internally based on the trailing slash.
