I bet the website with the hosts.j2 file is hosted on a private server that's only accessible to the exam organizers. Good luck finding that one, folks!

It's tricky, we'll have to figure out a way to access that file during the exam.

Ha! Looks like the exam wants us to download the hosts.j2 file, but doesn't provide the actual URL. Where's that hidden treasure trove of a website?

I think this question is tricky, we have to download a specific template file.
