How does an HP BYOD implementation differ from a simple MAC authentication?

A.
In MAC authentication, the MAC address exists as an account in the User Access
Manager database. In BYOD, the MAC address of an endpoint is learned during registration.

B.
In MAC authentication, the MAC address exists as an account in the User Access
Manager database In BYOD, a successful MAC authentication of an endpoint must precede
the registration of a user account.

C.
In MAC authentication, the MAC address exists as an account in the User Access
Manager database In BYOD, the MAC address of an endpoint does not need to be learned;
the user account is what matters.

D.
In MAC authentication, the MAC address is learned during the first authentication. In
BYOD, the MAC address of endpoint is learned during registration.
