Hi all,
Guys this is not a technical query but i really didnt know whom or where to ask so i am putting this question here for all experts (whom i respect by heart)
Sir how do you guys become expert in pre sales. I mean client can ask anything from anywhere. They can ask me on the fly that how many ports or modules are in 3900 series router ? they can ask me if stacking between 2960s and x is possible ? what about 3560x and 2960x and such. How am i supposed to remember all this stuff ?
I know there are experts here who may know it all but what is the approach for getting such expertise ?
Please guide me guys i will really appreciate your feedback on it.
