CIT 640-506 Exam

[Mohammed Hakim]

Hello Group,   I am a CCNA I have a book called "Cisco Internetwork Troubleshooting" Laura Chappell & Dan Farkas 1999 .. should this book be enough to pass for the New CIT Exam 640-506 or should I have the Cisco CCNP Support Exam Certification Guide or other books.     Thanks, Mohammed Hakim, CCNA
