I had some problems with some of the module-specific questions as we Use NPM and NetFlow but I dont oversee or use NetFlow that often.
But here is some of the things that I remember
Understand SNMP, WMI, NetFlow
NPM (and additional modules which I was extremely disappointed in. Wasnt this supposed to be a NPM exam?)
Basics for VOIPports & the TCP / UDP assignations.
L2 vs L3 differences.
NPM Stuff I rememberd
Report Wrtier (Coustom Reports)
Kind of reminded me of the Network+ Exam alot of the questions really didnt pertain to NPM as much as I thought it would.
There were a few Cisco Sepfic questions
Solar Winds Modules
NetFlow (Alot of these questions)
Thats all I can remeber took me about 3 and a half hours to complete. Came out dumb as a box of rocks... Felt like I went into the exam that way too...
