For anyone else preparing for C100DEV or C100DBA, in addition to MongoDB University and the official study guides, I’d also recommend checking out Pass4Exams. They provide updated practice questions and mock tests that mirror the real exam format really well, which can boost confidence and readiness on test day
Summary I hope this post will be useful for people who want to take the next step in their career and pass MongoDB certification. The range of knowledge as one can see is wide and sometimes you need to know the details, but this knowledge will make you a better specialist and will open more opportunities in front of you. I hope you pass the exam and find your name under MongoDB Certified Professional Finder!
