Second try was the charm! Passed with an 822. Not awesome, but it got the job done. Going for the BCMSN next. I'm hoping that will be a bit easier. Fortunately, this is where most of my experience lies.
Also, if anyone has successfully used Dynamips for BCMSN studies, let me know. I know you can use the switch NM and do some stuff with it, but I haven't played around with it much to see how much BCMSN stuff that you can do with it. Trying to figure out if I can get by without picking up some physical switches. Thanks!
