Answer is correct. We are not creating a container, only registering it and we need an error message if it does not exist. If we set "create_if_not_exists" to true, it will not display the error message but create the container and we dont want that.

You can resolve this by thinking logically. overwrite = False would mean, that we don't overwrite the existing file, but that we create a copy! create_if_not_exists = False won't create anything if there is an existing folder.

Correct, A: Register_azure_blob_container B: Create_if_not_exists = False First is easy, we are talking about storage accounts and a blob container. Second too, It should raise an error if the container does not exist, so it should not create it in that case, as there would be no error then.
