For instance, I've seen your posts where you said you learned some good concepts while studying for the mcsa MCSE back in the 90's.
That's true. But mostly I learned about the parts that weren't related to them, and mostly from third party sourced like Ed Tittle. Microsoft's own materials weren't bad, but not on par with good educators.
For connecting multiple switches (3 in this case), if your router has Gigabit LAN, is it best to to have a cord from 3 different ports on the router to each switch or to have the router go into 1 switch and then daisy chain the switches... or... does it really matter?
Neither. Router to Switch at the hub, then spoke other switches.
Correct. that is what I said, in a slightly more technical way.
