Implement Azure extended network - Azure Tutorial

- [Tutor] The exam may test your knowledge of implementing Azure Extended Network. And this is a feature I think you're unlikely to be able to fully configure and test, so I'm going to talk you through what it is, how it works, the high-level configuration steps with, a bit of demo, so you're fully prepared for exam day.
