CCNA Official Exam Certification Library, Third Edition, is the newest edition of the all-time best-selling CCNA self-study preparation package. This comprehensive review and practice package is designed for the latest CCNA 640-802 exams. The two books contained in this package, CCENT/CCNA ICND1 Official Exam Certification Guide, Second Edition, and CCNA ICND2 Official Exam Certification Guide, Second Edition, present complete reviews and a more challenging and realistic preparation experience. The books are updated to cover all the new 640-802 exam objectives, such as security, wireless, IPv6, and troubleshooting. Please note that while this is the Third Edition of the Library, the two books inside are Second Editions. This is correct, and the editions align differently because of changes in the names of the exams, from the old INTRO and ICND to the new ICND1 and ICND2 formats.
