I am relatively new to Teradata. I am actually looking to take a certification exam in teradata. However, I am confused by difference in the certification exams. I see two different tracks for the certification. One is V2R5 related stuff (like NR0-011) and the other is Teradata 12 stuff (like TE0- 121).
Could anyone please explain me the difference between the two tracks? which one is the latest and the most valued?
