What it takes to pass Cosmos DB Developer

DP-420 reports results on a scale from 1 to 1000, and 700 is the line on that scale, not a percentage of questions. Microsoft Azure converts your raw performance to the scale with a model it does not publish, which weights questions by difficulty. Two candidates can answer the same number of questions correctly and land on different scaled scores.

That has one practical consequence: nobody outside Microsoft Azure can tell you exactly how many questions you can miss. Any site that gives you a precise miss budget is guessing. You can still practice against the line itself: our Cosmos DB Developer practice exams score against the published 700, so a practice result reads the way the real one will.

A retake costs another $165.

Sit a full-length Cosmos DB Developer practice exam under the real time limit, scored against the published line, and book the real exam when you have cleared it more than once.
