During the course of a typical day—if there is such a thing as a "typical" day—network consultants are bombarded
with questions coming from all directions. These questions come from customers, peers, sales and marketing
teams, network administrators, and so on, and the list seems neverending at times. Network consultants, designers,
engineers, managers, and so on have developed an instinct over time and sometimes cringe or develop other
nervous habits when the phrase, "You got a second?" is uttered.
