Hi,
I have just started to learn networking. I'm using Packet Tracer and the free tutorials provided by Cisco. Unfortunately, I have already stumbled as I can't find the required .pksz files for the Packet Tracer Tutored Activity (PTTA) tutorials and in consequence I've ground to a halt. I'm sure you know how frustrating situations like this are. If you have a clue, please let me know. Thanks
