What settings and connection type is needed to externally boot a 2018 MacBook Air?

Looking to setup an external drive with OSX 10.12 so I can continue to work with several programs. What settings and connection type is needed to externally boot a 2018 MacBook Air? Will a specific external drive or enclosure work better than others?


Thanks.

MacBook Air 13", macOS 10.14
