    Personally, I hate this type of question because find them meaning less.
    Is this a real CCNA exam question Rowan?

    Hi Rowan,

    The structure of the fiber is: Jacket encase Buffer, Buffer encase Cladding, Cladding encase core. In addition, we use light to transmit data through the core. Therefore, B and D are the right answer… Good Luck!

    Hi Rowan,

    Honestly, I don’t know the answer but I am sure that A and E are the wrong statements because the BNC Connector is for Coaxial Cable, so A is wrong, and RJ45 is a connector is for twisted pair, thus E is wrong.

    I hope this helps!
