• Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
    Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

So I took a test for a Camera Technician job working for the city, and it made me realize I don't know jack about networking. Well, I was pretty sure for most, but there were some questions I definitely guessed on.

What's a quick and effective way to get spun up on network admin concepts and troubleshooting techniques? I probably won't be hired this round, but I would like to be prepared if the job comes up again and they call me.

(Edit: I looked it up and I correctly guessed that the unique 48-bit address that identifies a device on the LAN is the MAC address. +1 on my score! 🙌)

Not sure about quick. If you're willing to put in a little time, many community colleges offer courses. Many are Cisco-created and sponsored CCNA. Decent chance the teacher is knowledgeable (most of the ones I had were teaching as a side from their normal networking-based jobs). There should be al least a virtual lab available, if not real hardware. When I did it some years back, the 101 course was all the basics (IP addressing, subnetting, the OSI layers, etc.)
