I currently hold a valid CCNA certification and it expires by end of 2009.
Does taking up 640-721(CCNA Concentration - Wireless) exam helps me to extend the validity of my CCNA certification ?
But if you go here: http://www.cisco.com/web/learning/le3/learning_about_recertification.html it says
CCENT, CCNA, CCDA Complete one of the following recertification options:
Pass your current certification exam. For CCENT and CCNA, ICND 2 will also recertify.
Pass a CCNA Concentration exam (wireless, security, voice)
Pass a current Specialist exam (excluding Sales Specialist exams)
Pass any Professional level exam bearing a 642 prefix
Pass a current CCIE or CCDE written exam
Achieving or recertifying any of the certifications above automatically extends your active CCENT, CCNA, and CCDA certification(s) up to the point of expiration of the last certification achieved
Any idea how to verify which information is correct?
