You'd only need to draw a layer 2 diagram, if the layer 2 topology is
complicated. If you do all the internetworkexpert labs (free stuff my way
for the plug guys), you'll come across labs that get so complicated with
VLANs, that you could not pass without drawing one. The key is to practice
these variations, so when you face the real lab, you'll know what you need
to do based on what's given to you. In my 2 lab attempts, I did not need to
draw a layer 2 diagram.
