I took and passed the Network+ Exam today with a score of 852. The overall test was not too bad - 100 questions and most were very short answer. I think the total test time for me was around 45 minutes.
The test seemed to cover pretty much every part of the objectives. I would recommend knowing your cabling, routing protocols, troubleshooting commands, the troubleshooting steps and definitely the OSI model and what protocols and hardware work at each level.
I used the Mike Meyers book and the Lammie book. Both helped a great deal. I also used the Selftest software for this test.
Overall my recommendation is to download and learn all of the objectives (good advice for any CompTIA exam). There were a couple of WTF questions

:, but overall they seemed to follow the objectives fairly well.
Good luck to everyone preparing for this exam.
