I'm currently studying for the CCNP SWITCH exam and was wondering if you guys knew where I could find lab practice scenarios. I have two 3550s and two 2950s. Ideally I'd like to find problem scenarios that require me to implement features (HSRP, STP, VACLS, etc), and for the scenarios to also include the solution so I could verify my work. I know I could make up my own, the only problem with that is I tend to pick stuff I know.
