Cisco CCNA Exam #640-607 Certification Guide (3rd Edition)

It’s almost a prerequisite for employment in the data networking industry (and, if you believe the voice-over-IP people, the voice networking industry as well): The Cisco Certified Network Associate (CCNA) proves that you know your way up and down a protocol stack, can tell a bridge from a repeater, and can configure a packet filter. It has some emphasis on Cisco Systems products, naturally, but the CCNA’s scope is so broad as to be relevant no matter whose gear you use. Cisco CCNA Exam #640-607 Certification Guide is the definitive work on the CCNA subjects and is one of the two best values among the training aids available (the other is Todd Lammle’s CCNA: Cisco Certified Network Associate Study Guide, Deluxe Edition). This book distinguishes itself with the quality of its practice questions and lab exercises, its knowledge-assessment quizzes that help you decide how to use your study time, and its clear and numerous conceptual diagrams.

Wendell Odom, both a Cisco Certified Internetwork Engineer (CCIE) and a Cisco-rated trainer, doesn’t spend too much time on test-preparation gewgaws, as do many books with CCNA in their titles. This is a reference and tutorial book through and through, and you’ll use it long after you’ve passed the test (and you will pass the test, if you study Odom’s work hard enough). He’s a master at combining explanatory text (and graphics) with reference materials (like tables of commands and their modifiers). Plus, there’s a CD-ROM containing exam simulations in the newly revised format. –David Wall
