Another day, another SANS certification (my 8th). Passed GMON. This was probably the most straightforward test since GSEC. I used my own index as well as the index that was provided in the class. Between the two, I didn't have any issues finding the answers during the test. I passed the first practice test without consulting an index and barely cracking the books. Unless you are new to SANS the concept tested here should be familiar. Just read the books a couple times over and build an index and you should be good to go for this one.
