According the latest update of cisco web site on CCIP, the exam "642-901", "642-892 Composite" will be expired on July 31, 2010. Detail please reference following link
If the above exam was passed on or before April 2010, what will the max months be allowed by Cisco for the candidate to complete the rest of exam "642-642", "642-661" and "642-611" after 31 July 2010?
Grateful if the reference link would be advised. Thanks
In general, professional level exams are valid for three years. So, you will have 3 years from the data of passing an exam to complete the rest of the exams required for the certification.
Hope this helps.
