In 2009 February I take my CCNP Voice (previously call CCVP). I did the exam 642-642 in Septembre 2008. Now I will go to do specialization career IP Telephony Design and there is the same exam. My question is: Is valid this exam or after pass 04 years I have to do again this exam?
You will need to re-take the exam
Do certification exams expire?
* Exams required for CCENT, Associate and Professional certifications are valid for three years from the date the exam was passed. Exams for the Specialist certifications are valid for two years from the date the exam was passed.
