I currently hold a valid CCNA and CCDA. I am about to attend the Cisco QOS course and will take the 642-642 exam. I understand that it will recert the CCNA and CCDA. Will that make them both valid for another 3 years from the date I pass the 642-642?
Also each time I take another 642 level exam, does that start the 3 year clock over again on the CCNA and CCDA?
