Contains a comprehensive practice test and an answer and explanation chapter at the end of the exam.

Gives the reader the competitive edge by quickly showing which areas may require further study.
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 modelled 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 and security strategies, as well as 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, Amazon.com
