Certifications and certification tests

“

- [Instructor] You may wonder why you need to know this method. Well, I would say that one of the first reasons is certification and certification tests. If you're going after any certification, then you can expect that there will be some IP addressing laced in if it's anything that has to do with networking. For example, the CCNA certification. Yes, it's all about Cisco gear, and how you work with Cisco equipment, but interlaced throughout that test are also questions about IP subnetting. In other words, you have to understand the IP subnetting in order to be able to work your way through the smoke and mirrors that is the rest of that question. It's the same thing with Microsoft. There are many Microsoft certifications, but anything that has to do with IT is going to have some element of subnetting in it. CompTIA is the same way. If you're going after an A Plus certification or a Network Plus certification or even a Security Plus certification, you're going to have to know about the IP addressing. You're going to have to know whether the problem is actually the fact that the IP addressing is wrong, or at least be able to work through that and eliminate that as a possibility. Even VMware, virtualized computers. Virtualized computers still use IP addressing. Any kind of certification that you look at that has anything to do with networking.
