Comptia Net+

Posted by exorcist in Interesting

I passed the Net+ exam today with an 805 out of 900. Minimum score is 720. I think I got by more on good logic and troubleshooting skills than I did on knowledge. A lot of the test focused on enterprise networking technologies like WAN. I’m not too good with Fiber Optics, frame relay, leased lines, etc. I never managed a business grade firewall either, so I was shaky on the port numbers and protocols. I was glad I studied up on subnetting and supernetting. . . some people said that it didn’t feature much on the Net+ exam, but that wasn’t my experience at all.

Some questions definitely left me scratching my head. Differentiating between dynamic routing protocols? I felt lucky that I could recognize RIP. I got no clue which alternative would have shorter “convergence” time. And I don’t have any idea why MAC Address filtering would have more overhead and be less effective on some types of cables compared to others.

I was pleased that there was next to nothing about IPv6 on the test. It’s hard enough calculating IPv4 addressing logic without having to do much larger numbers, and in Hex to boot.

Comptia wants you to take their stupid survey after the test, and they have devised a method of pure evil to accomplish this. After you finish the exam, they refuse to tell you your score until you complete the survey. Those fifteen questions never seemed longer.
