    I'm goign to ahev a go at Answer: C.

    Don't know anything about WEP really, btu am actually looking into learning what it's all about at min, so this QOTD has come just in time :D
    Some links all about WEP would be nice, anyone :?:

    My mad, but probably compeltely wrong theory, is that the destination address isn't encrypted.
    My thinking si that if their's routers inbetween, they may not be WEP enabled, therefore they won't be able to forward the packet.

    But, if the destination isn't encrypted, then any routers, even one's that aren't WEP enabled, can forward the address.

    I think i read somewhere once that if you want to sue WEP, then all routers inbetween source and destination need to be WEP enabled also.

    That's all compeltely wrong btw (probably), I can but try.

    Thanks :!:

    C is my answer too. If the Mac, IP and Payload were transmitted unencrypted then you would be giving away vital info to an potential hackers who may try to attach to your wireless network. As flex says the destination IP would need to be unencrypted so that the packet could reacj it's destination.

    I'll go for C also, a logical "guess" as Phil points out the other parts would be giving away vital info to an potential hackers.

    Another good Q Trip [​IMG]

    Same thoughts as me guys, you wouldnt want your MAC, IP or data to be unencrypted, so i'll go for C.

    For the sake of controversy, I'm going to say A.

    Something tells me that the "hard-coding" of the MAC would make encrypting it unnecessary.

    OK, shoot me now ....

    Time's up. The answer is A. Layer 3 and higher data is encrypted by WEP but Layer 2 data including MAC addresses are transmitted in plaintext. This includes the Access Point's beacons. Congratulations, Gav. You're a winner. :)

    Now if you'll excuse me, I think you''ll find my head is well and truly stuck in the CertForums doors :eek:
