Show answerHide answer
Correct answer: (A) I and II are true; III and IV are false.
Explanation
Statement I– True, High speed Ethernet can utilize various media, including optical fiber. It's not limited to just copper cables. Statement II– True, the definition of PPPoE is to encapsulate PPP frames within Ethernet frames. Statement III– False Since high speed Ethernet can work on optic fiber, this statement in incorrect. Statement IV– False, The correct encapsulation is PPP frames inside Ethernet frames.
