The encapsulation of Extensible Authentication Protocol $($EAP$)$ messages is often used in a wireless LAN. During the handshake process over Point$-$to$-$Point Protocol $($PPP$),$ both systems determine the authentication protocol to use. Other factors are also determined, such as connection parameters and the speed of data. Authentication occurs using:Question $9$ options:A$)$ the most secure protocol.B$)$ the first available protocol.C$)$ Extensible Authentication Protocol $($EAP$)$ only.D$)$ Challenge Handshake Authentication Protocol $($CHAP$)$ only.
