Partitioning strategy finally clicked. Passed first try.
Coming from a SQL background, the shift to Cosmos DB data modeling was tough. The practice questions on partition key design were exactly the challenge I needed.
Still studying but the change feed and consistency level questions are making concepts click in a way the docs alone did not. Good coverage of the SDK side too.
DP-420 is genuinely hard - the consistency levels and global distribution trade-offs require real depth. I failed my first attempt and came back to practice here before my second. The questions on multi-region writes and conflict resolution are the kind of detail that separates a pass from a fail.
