For example L2 is when the NAS is going to be adjacent on the same L2 segment of the client. L3 generally is better since the NAS does not have to be adjacent to the client (more scalable)
In-band is when the traffic passes through the NAS all the time. OOB is when only the authentication and posture passes through the NAS, then all normal traffic is redirected to the appropiate VLAN. For OOB you need Cisco Switches.
One NAS server can only serve certain connections, therefore depending on your topology you might need more than one NAS servers and a Lite-Manager or Standard Manager.
