I started studying for the lab in May, was wondering if anyone could share their studying strategy. I started by ordering the vendor labs (IPexpert) and virtual rack time (Proctor Labs). Soon after, I realized that there really is no way to save your configurations for the CallManager or Unity or CRS, which is a problem since later lab modules require that everything before it to be built (how can you test gateways and gatekeepers without your dial plan that was built in the previous module.) If you want to work on trouble points in module 7, for instance, you are going to have to rebuild pretty much everthing in the previous 6 modules, which REALLY sucks. Has anyone else found this issue vexxing? The only thing I can imagine that will be a big help is the Multi-Protocol challenges (about 15 of them) that are self-contained and pretty much iterate the content of the first 15 modules.
If you are studying for this lab, how are you approaching it?
