I've been a relational DBA for years and still found the C100DBA security and replication domains genuinely challenging. Working through these practice sets changed that. Passed on my first attempt and felt confident doing it.
Replica set elections tripped me up until I drilled these.
I was switching from app development into database administration and the C100DBA felt like a lot to absorb - replication, sharding, and performance tuning all at once. NerdExam helped me build a real mental model before exam day. Not a silver bullet, but easily the most useful study resource I found.
Coming from a SQL background, the data modeling section was a real mental shift. Practice questions on embedding vs. referencing helped me think in documents, not rows.
