Candidates must first pass a written qualification exam and then the corresponding practical exam. You must pass the practical exam within three years of passing the written exam in order to achieve certification. Your first lab attempt must be made within 18 months. CCDE certifications are valid for two years and must be re-certified every two years thereafter.
To re-certify, pass ONE of the following before the certification expiration date:
- Pass any current CCIE Written Exam OR CCIE lab 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.
