Gentlemen,
Please read the information on the AWS Website for
CWI exams. It says 'ONLY' D1.1:2010.
http://www.aws.org/w/a/certification/CWI/There are other locations that still say the 2006 & 2008 editions will be allowed and at the last Phoenix exams I assisted at several people had the exam acknowledgement papers from Miami that stated that the examinee could use 2006, 2008, or 2010. Now, the exam I proctored was in March and the 'Note' says effective June 1, 2011.
AWS needs to get all aspects organized and together on this. BUT, the information that the proctors are given says only 2010 and the NOTE on the website says ONLY 2010 effective June 1, 2011.
While I agree that you could more than likely pass with any of the afore mentioned editions, you won't be able to challenge any questions that may make the difference between passing or failing.
Have a Great Day, Brent
