Why are Server Manager options for Nano grayed out?

Q. I'm managing a Nano Server via Server Manager however Remote Desktop Connection and Configure NIC Teaming is greyed out. Why?

A. This is to be expected. While Nano Serve can be remotely managed using Server Manager it can only expose features compatible with Nano Server. Nano Server does not support a remote desktop connection nor traditional NIC Teaming (you must use Switch Embedded Teaming).
