    Yeah that subnet mask question wasn't sure on made some BS up about how the network IP being different so it meant it must be on another network trace table was ok I made that exact question up after seeing the depth first search in a past paper 😀

    Potentially 68-69, that's the range of other papers typically. Even 67 if the grade boundaries are unusually low.

    Why are you assuming there aren't any C grade students on TSR?

    I think you had to write about performing a AND operation using the subnet mask and IP address. You would then compare the result to the subnet IP address. If they are the same then its on the same subnet otherwise its not so you have to send the data to the router.

    I found that paper very easy personally. The only oddity for me, was the subnet mask question. I was confused to how the computer would actually tell and what process it would go through. I said something about using its subnet to send the packet of data to the default gateway? Where the default gateway was sent the packet by the switch it was directed to? It was quite a muddled answer.

    Apart from that though, pretty confident in all my answers. Will probably drop a few marks for long answer questions, but I'm thinking a high A or A* here.

    I just said the subnet mask defines the size of the network so by using that with the ipaddress you know whether the computer is on the same LAN or not

    if someone gets the paper then between us we could probably come up with a mark scheme.

    I think the other is to prove it definitely came from the person that sent it so if A sent it, the digital certificate can tell you whether it did come from A or not

    (The other being that it is definitely the original message and that it hasn't been tampered with or changed)

    Yeah, I never learnt any reason other this. I just said to ensure that the message didn't get corrupted during transmission.
