The prestigious Cisco CCNA certification is going to become even more prestigious later this year - and from all accounts, even more difficult! The current 640-801 exam will be phased out on November 6, giving candidates plenty of time to prepare for that exam.

On a personal note, I've taken Cisco certification exams with the help from http;//www.testslive.com for almost a decade as well as taking exams from other vendors for about 14 years, and I've never been big on taking a brand-new exam. Some people like to do so, though- it's all a matter of personal preference.
