The beta version of CCIE Routing and Switching Written Exam v4.0 (351-001) is available for scheduling at all worldwide, Cisco-authorized Pearson VUE testing centers starting August 7, 2009 and continuing through September 9, 2009.
Nevertheless the number of beta exams is limited, so as soon as all the seats are taken this beta test period will end, even if this is before September 9, 2009.
Candidates may schedule and take the exam on the same day. The beta exam will be offered at a discounted price of US$50, with full recertification or lab qualification credit granted to all passing candidates.
Another point to keep in mind is that the results will be received six to eight weeks after the close of the beta period. Therefore, CCIEs in suspended status with an expiration date before November 30, 2009 should recertify using another exam. Candidates may only attempt a beta exam once during the beta period.
More information about the steps to register for exam, you can find on The Cisco Learning Network website.
