Wired client authentication | Radius server or ISE?

I recently ran across a practice test question that went along the lines of:

 

"When a wired client connects to an edge node in an SDA fabric, what decides if the client has access to the network?"

 

The choices included ISE and a radius server. Wouldn't they both be correct answers?


Any input is appreciated.

Yes, it's a poor question if asked that way since both are technically correct. ISE is of course a radius server, and you can leverage a third party radius server + ISE for SDA. If they had used creative wording then maybe they were trying to trick you, you can't run SDA with only a third party radius server, you still need ISE.
