So called 278 and 269 question dump are available on net for free of cost.One of my friend followed the same questions what you posted above and failed his Exam Yesterday(02-JAN-2011).
Never ever depend On So called dumps! It is better to Learn/Understand the concepts behind it. And then practice the dumps.Don`t follow the answers blindly.No one will give guarantee for the Questions.

Well said! Those that follow dumps are just dumb. The only interest of dumps is to find where they are wrong and why.

I just took the exam last month and passed (the second time). As far as practice exams, I used Kaplan. It cost $69 for a month and I think it really helped. The first time I took the exam I just used the SQL Certified Expert Exam Guide by Steve O'Hearn and the free exams that came with the book were not representative of the actual exam, IMO. The Kaplan test was better. It's a hard exam, and I have used Oracle SQL pretty regularly for the past 6 years.
Good Luck!
