Passed my N+ exam today

. But let me tell you I felt cheated because alot of the questions were ridiculous. I didn't feel like I was being tested on what I know but more like they were trying to trick me. Needless to say I was very relieved to find out I passed.
Also as promised I tried to remember as much as I could about the topics. I had a bunch of network support questions.
1. Wireless and sources of interference
2. IP address classes and ranges
3. Network devices and OSI/TCP/IP layers
4. Alot of questions on DNS
5. Fiber technologies
That's all I can remember at the moment. Will give more input if I can recall any more. My only piece of advice is that it seemed like all of the question involved weeding out the wrong answer to find the correct one. So instead of them saying what layer does UDP operate at which was one of my questions by the way they would say which protocol doesn't operate at the application layer. I had a 12 page review sheet that I used I will Link later today if anyone wants to check it out.
