Happy New Year! I've been on vacation for three weeks, so its taking a bit of time to get through my email and other work.
One question that was emailed to me recently was asking about the availability of FREE sample or assessment questions. We used to have a set of free assessment questions available but now there is a $10 charge for each attempt. To access these exams, see: http://www.ibm.com/software/data/education/cert/assessment.html
An alternative to these $10 assessment exams is for you to borrow or purchase one of the study guides that provide a collection of sample questions AND answers. Here is a list of the books that I'd suggest:
For Exam 700:
Understanding DB2 - Learning Visually with Examples by Raul Chong, Dwaine Snow, Sylvia Qi, Clara Liu
DB2 Universal Database V8.1 Certification Test 700 Study Guide by Roger Sanders
Teach Yourself DB2 Universal Database in 21 Days by Susan Visser and Bill Wong
For Exam 701 or 706:
DB2 Universal Database V8.1 Certification Exams 701 and 706 Study Guide by Roger Sanders
For Exam 703:
DB2 UDB V8.1 Certification Test 703 Study Guide by Roger Sanders
For Exam 704:
Advanced DBA Certification Guide and Reference for DB2 Universal Database v8.1 for Linux, UNIX, and Windows, First Edition Dwaine Snow and Thomas Xuan Phan
These books range in price from $35 to $50 and contain the information to help you prepare for the exam PLUS 200 or so sample questions and answers per book. This sounds like excellent value for the price!
I wish you all the best for the coming year!
