Law Buong Yiek, CCIE #26982
I used INE's CCIE Service Provider materials for my preparation to obtain my CCIE Written and Lab exam. The Service Provider workbook indeed helped me to understand all of the technologies in depth, and polished my troubleshooting skills and understanding. I would say INE played a major part in helping me pass the CCIE exam. Last but not least, the IEOC forum is a MUST to discuss all the knowledge required. I'll recommend that everyone use INE to accomplish their success.
