If you have the money, of course just copy the config. as exactly on the lab exam.

If you want to save money, you can get a bunch of used 2500/2600/3600, 1 router with at least 4 serial ports as frame relay switch, at least one 3550/3560 and at least one other switch (may be another 3560/ 3550 or 2950).

For features that are not supported  on the above equipment, you can rent some online rack time or use dynamips(but it cannot support switch emulation).  This may be the most cost effective way.
