I posted this message on the "LAN,Switching and Routing" forum already but then I realized that "Getting started with LANs" is probably more proper place to start this type of topic. Posting in the two different forums was not intentional and I didn't do it to have more "visibility".
And here is a topic:
I am building new LAN for my office. I have two 3560 running L3 connecting to MPLS, two 3750 and bunch of 2960 and 3560 PoE switches. Which would be the best design. Please look at 3 attached scenarios (diagrams) and express your professional opinion. Any ideas welcomed.
