I am about to take the Composite test (642-891) to recertify my CCNP. I am using the Cisco Press books (BCSI & BCMSN) and have found that the BCMSN book only discusses IOS commands for switches. However, in doing some practice tests and other research, I'm finding that CATOS commands are still included. I work on switches everyday, but not many of them are CATOS anymore and I don't want to get into the test and be surprised by some CATOS command questions that I haven't seen or used in a while. Does anyone know if the test includes CATOS items? And if so, I wonder why the Cisco Press book doesn't include them.
