MCDBA exam

Who are preparing for Oracle certification, Microsoft SQL server exam is getting easy for them. Most questions of exam 70-228 have a selection of answers that all seem correct, but in reality, the right answer is the one that best solves the question. 228 is the SQL server administration core exam and 229 is SQL design core exam. It’s all SQL server database design and administration exam. Microsoft Certified Database Administrator (MCDBA) on Microsoft SQL Server™ 2000 candidates need to pass three core exams and one elective exam that provide a valid and reliable measure of technical proficiency and expertise in the implementation and administration of SQL Server databases. I was always being good in SQL programming and MCDBA certification seems good to me. Do things what you like? I passed 70-228, now going for 229 exam. Some says me that are twins, i want to know how much it different from 228. What extra effort should I need to give?
