WSUS Processes

A question for the WSUS experts out there. When WSUS updates are approved, does WSUS scan the local system (WsusContent) first before going out to download the updates? Or is it the other way around?

We have an ongoing discussion on how the process works. We have multiple WSUS instances on closed networks (no internet) which we import the updates to and copy the data to the local store. Some think that WSUS will first attempt to go out and download the updates, then failing that, read the local store to see if the data exists and then report it as "downloading". And some think it's the other way around.

I can't seem to find any definitive answer to this in any of the documentation.

Thank you in advance.

    First of all, Update Files and Languages configuration will be written to the database according to your settings. Here is the reference picture:
