This is pretty cool. IE is running a monthly “Brainteaser” in their newsletter [emphasis mine]:
Brainteaser: Win $50 Amazon Gift Card or 10% Off Your Next Internetwork Expert Purchase
As a new feature of our newsletter, we will begin to include occasional CCIE “brainteaser” quizzes designed to test your CCIE knowledge and problem-solving skills. At the end of April, we will randomly choose five winning names from all correct answers provided.
Winners will win a coupon worth 10% off the price of any of our training packages for R&S, Security, or Service Provider materials or a $50 Amazon.com gift card! Note that the 10% off discount will be usable with any other discount code you may already have. Please email your solution config to firstname.lastname@example.org by April 30th, 2008!
