Just wrote the second of the Database developer exams: 70-442. Designing data tier and optimising data access.
I found it easier than the other database developer exam, but still, it wasn’t easy. If you don’t know your stuff, you are going to struggle.
Personally, I’m not very fond of the case study based exam format. When I tried to read through the case study before answering questions I almost ran out of time. Now I go straight to the questions and skim through for the appropriate info for each question.
Next up, the upgrade exam from MCDBA to the new DB Admin.
