Description:
More of an exam-preparation companion than a primary preparatory text, Network+ Practice Tests (Exam Cram) is nonetheless a good investment for those serious about passing CompTIA's new Network+ exam. The book has more than 300 multiple-choice questions jammed into its four practice tests, and all questions are modeled after the format used in the actual Network+ exam. Some are extremely basic, drawing on one's knowledge of standard networking protocols and technologies, whereas other questions present what-if scenarios pertaining to network topologies, fault-tolerance, security strategies, and Internet-centric network problems and configurations. Each practice test is followed by two answer keys. The first simply lists the correct choices for each of the questions; the second provides in-depth explanations of why the selected answers are right. For example, the explanatory text for a question having to do with Token Ring networking in the first practice test goes into which company invented Token Ring--IBM--as well as how it differs from Ethernet in terms of topology and packet transmission. In addition, each explanation ends with a reference to the pertinent chapter in Certification Insider Press's sister publication, Network+ Exam Cram. Not subtle, but a good way of tying the texts together. --Sarah L. Roberts-Witt
