In working on live equipment, one notices the effect of time passing, particularly with distance-vector protocols. Often a change will not produce a visible effect until timers have elapsed and packets have time to propagate from one router to another. Are the simulations used in the exams also driven by internal clocks, or are changes artificially accelerated? Are there likely to be cases where you have to spend real exam time waiting for things to time out before you reach a desired result state?
Anybody know for sure?
