Snap Help

Hey everybody. I’m taking a networking course at BCIT and all of this is very new to me. I’m just learning how to create my first virtual machine using virtualbox. I made a good working copy of Ubuntu. And I now have to make an Ubuntu server. I’ve downloaded my ISO and I’m starting to create everything but now I’m asked to select what snaps I would like to use. I’ve read about them and I understand what they are but I don’t know which ones would be useful to me at this point. I’m only one month into my course. And it’s a very rushed course. Hope someone can point me in the right direction. Thank you
