I have been reading as much as possible for some time now as I continue to prepare for my CCNA exam. I decided it would be a good idea to read over a number of different books on the same topic so I can get a better understanding of what I am learning. The command lines and the foundation knowledge of Cisco switches and routers is the easy part for myself. What I find difficult is the IP Addressing and Subnetting areas. The idea behind it all is easy enough, and I can do the math that is needed to convert from decimal to binary. My problem is I can not do it fast enough. If Cisco exams were not timed I would have no issue, however that is not the case. I am currently reading the CCENT/CCNA ICND1 Offical Exam Certification Guide and in there Wendell Odom states, “In fact, you should be able to answer in 10-12 seconds a straightforward question such as, In what subnet does IP address 10.143.254.17, with mask 255.255.224.0, reside?” It would take myself much longer than 10 seconds to answer that question, so I will obviously need to practice more before I am ready. I plan on spending the remaining days in September and October doing just that.
