The Network+ Practice Questions Exam Cram 2 provides readers with more than 500 practice test questions as well as complete answer explanations, giving readers the perfect complementary tool for their Network+ studies. Features the ever-popular "Cram Sheet" tearcard, which is used for last minute preparation. This exam certifies that candidates know the layers of the OSI model, can describe the features and functions of network components and have the skills needed to install, configure, and troubleshoot basic networking hardware peripherals and protocols. The Network+ exam, developed by CompTIA, is only five years old but already is held by nearly 100,000 individuals (an adoption rate that is even faster than A+, which is CompTIA's flagship certification). It is now being taught in schools and has grown 120% in the past 24 months. Currently, approximately 4,000 candidates are sitting the Network+ exam each month. The certification is endorsed by Microsoft (as part of its popular new MCSA program), Cisco, Novell, and 3Com, among others.
