With more than six months of exam results now available, Cisco is able to report that the troubleshooting components of the CCIE R&S v4.0 and CCIE Voice v3.0 lab exams are performing well in validating expert level networking skills. Considering these results, Cisco has decided to eliminate the Core Knowledge questions from the current CCIE R&S v4.0 and CCIE Voice v3.0 Lab Exams. Beginning on May 10, 2010, CCIE R&S and CCIE Voice Lab Exams, in all global locations, will no longer include the four open-ended Core Knowledge questions. The total lab time will remain eight hours. For the CCIE R&S Lab Exam, this means candidates will begin with the two-hour Troubleshooting section, followed by a six-hour Configuration section. For CCIE Voice, candidates will have the full eight hours to complete the integrated exam. At this time, only the R&S and Voice tracks will be eliminating the Core Knowledge questions.
