It's been a bit longer than I anticipated in obtaining this certification, and I learned or re-learned way more about some networking items I will likely never use again, and/or haven't used in years such as information regard hubs. Reminds me of the 10base5 or 4wireE&M telephone signaling that I studied while in the Air Force and never used while I was there or since.
Do they even still make or use hubs? (I know that some companies still have/use them) but why when you can buy a 100Mb workgroup switch for under $15?
If you need to send something to me, or you need to verify that something came from me, here is my PGP / GPG / GnuPG public key
