For DP-300, MeasureUp sells a dedicated practice test of 160 questions (last updated 12/2022). You can sit it in Certification Mode under exam-like conditions or switch to Practice Mode to drill chosen objectives with explanations, and it comes with a written Practice Test Pass Guarantee. Its product page lists a 12/2022 update, older than Microsoft's October 2026 skills outline, so check how closely it tracks current objectives.
The difference shows up after the score. MeasureUp's reports break your DP-300 results down by objective, and separate Assessment products are available, but no adaptive roadmap or predicted readiness date is built on them, and there's no AI tutor to work through a wrong answer.
Edureify maps that DP-300 practice onto a plan: misses on Always Encrypted, automatic tuning or geo-replication change what you study next, and the AI tutor can unpack why one HA/DR option met an RPO target and another didn't. A live Readiness Score then predicts when you'll be ready to sit DP-300.
