Hi Rajnath,
Here you go
CCNA Routing and Switching certifications are valid for three years. To recertify, pass ONE of the following before the certification expiration date:
- Pass the current ICND2 exam, or
- Pass any current Associate-level exam except for ICND1 exam, or
- Pass any current 642-XXX Professional-level exam, or
- Pass any current Cisco Specialist exam (excluding Sales Specialist exams or MeetingPlace Specialist exams, Implementing Cisco TelePresence Installations (ITI) exams, Cisco Leading Virtual Classroom Instruction exams, or any 650 online exams), or
- Pass any current CCIE Written Exam, or
- Pass the current CCDE Written Exam OR current CCDE Practical Exam, or
- Pass the Cisco Certified Architect (CCAr) interview AND the CCAr board review to extend lower certifications
When using a higher level of certification to extend other certifications, the expiration date of other certifications will extend to the expiration date of the higher certification (i.e.: If you have one year left on your CCNA Routing and Switching certification and you earn a CCIE certification (which has a two-year certification life) then both your CCIE certification and your CCNA Routing and Switching certification will expire two years from the date you achieved the CCIE certification).
