Not  sure  if  the scope is limited to discussing certain OSes, but on
Windows we often had/have training class PCs with just one interface.

Selecting  the  first  interface seems like an easy way out, but in my
experience  (once  again,  on Windows) it doesn't make much sense - in
almost  all cases encountered there is some bluetooth or VPN or pseudo
WiFi   adapter   at  the  first position in the list when there's more
than one interface. But that's just my 2 cents :-)
