You failed the DP-900. Your score report is in your inbox. You’re wondering if you can retake it tomorrow, how much it costs, and whether there’s a waiting period that’s going to waste your momentum.
There is. And it’s going to cost you money.
Here’s what actually happens next.
What Your Score Actually Means
Your score report shows a number between 0 and 1000. Microsoft set the passing score at 700. If you scored 680, 695, or even 699, you failed. The exam doesn’t give partial credit. There’s no “almost passed” on your transcript.
The score report breaks down your performance by domain:
- Cloud concepts and big data essentials (25-30% of exam)
- Relational data in Azure (25-30%)
- Non-relational data and analytics in Azure (25-30%)
- Data visualization and reporting (10-15%)
Your report shows which domains crushed you. If you scored in the 30th percentile on “relational data in Azure,” that’s where your retake focus lives. Not everywhere. Somewhere specific.
Many candidates miss this detail. They see the overall score, panic, and study everything again. That’s inefficient. Your score report is a map. Use it.
The Real Reason You Failed Microsoft Azure Data Fundamentals (DP-900)
You didn’t study the right material, or you didn’t study enough of it.
Most DP-900 failures happen for one of three reasons:
You crammed for two weeks instead of studying for four. The DP-900 covers distributed databases, data warehousing, streaming architecture, relational vs. non-relational design decisions, and Azure-specific pricing models. Two weeks of weekend study isn’t enough surface area. You need time to read, labs to hands-on, and practice tests to identify weak spots.
You took a practice test once and called it ready. One practice test doesn’t validate knowledge. You need minimum three full-length practice tests, scored, reviewed, and retaken. If you got 65% on your first practice test and didn’t take another, you weren’t ready. The passing score is 70%. You were ~50 points away.
You studied the concepts but not the Azure-specific details. The DP-900 isn’t a general data engineering test. It asks about Azure Blob Storage vs. Azure Data Lake, Azure SQL Database vs. Azure Synapse Analytics, Azure Cosmos DB partition keys, and specific pricing tiers. Generic data knowledge fails this exam. You need Azure details.
Look at your score report. Identify which domain(s) dragged you down. That’s your weakness. Study that domain harder the second time.
What To Do In The Next 48 Hours
Step 1: Don’t retake immediately.
Microsoft Certification enforces a waiting period. You cannot retake the DP-900 within 24 hours of your first attempt. You must wait at least one day. Most candidates can retake after 24 hours, but some regions or situations have longer holds.
Check your exam result email. It clearly states your next eligible retake date and time. If it says you can retake in 24 hours, you can schedule for tomorrow afternoon. If it says 7 days, something else happened—contact Pearson Vue support.
Step 2: Schedule your retake right now.
Go to the Microsoft Learn certification dashboard or Pearson Vue’s website. Book your retake appointment for exactly 7 days from today. Not 3 days. Not tomorrow. Seven days. That gives you time to study without rushing and guarantees you don’t lose focus. Commit the date to your calendar.
Step 3: Calculate the cost.
The DP-900 exam costs $99 USD (or regional equivalent). You already paid $99 for your first attempt. Your retake costs another $99. That’s $198 total out of pocket—unless you have an exam voucher, a free Microsoft Learn credit, or an employer covering it.
Microsoft Learn credits sometimes include free exam vouchers. Check your account. If you have credits sitting there, use them before spending another $99.
Your Retake Plan
You have exactly seven days. Here’s how to spend them.
Days 1-2: Diagnosis and targeted review
Re-read your score report in detail. Which domain scored lowest? Start there. If “relational data in Azure” was 45% and others were 65%, spend 4 hours on relational topics: normalization, ACID properties, Azure SQL Database tiers, and when to use SQL vs. NoSQL.
Use Microsoft Learn modules specific to that domain. Not the entire DP-900 learning path. Just your weak spot. That’s 4-6 hours of focused reading.
Days 3-5: Practice tests and gap filling
Take a full-length practice test. Score it. Identify questions you missed. Read the explanations. Find the Microsoft Learn module that covers that concept. Study it. Repeat for a second practice test.
Do not retake the exact same practice test you took before your first attempt. Most platforms (Whizlabs, Examtopics, MeasureUp) have multiple versions. Use a different one.
Aim for 75%+ on your practice test before day 7. If you’re stuck at 68%, you’re not ready. Extend your schedule.
Days 6-7: Final review and exam readiness
Take a third practice test. This is your baseline confidence check. If you score below 72%, postpone your retake another week. Seriously. Pushing into an exam you’re not ready for wastes another $99 and demoralizes you.
Review only the questions you missed on all three practice tests. Don’t re-study passing topics.
Night before the exam: sleep 8 hours. Don’t cram. Your brain needs rest.
One Thing To Do Right Now
Stop reading this and book your retake appointment for exactly seven days from today on Pearson Vue’s website or your Microsoft certification dashboard.
Don’t book it for tomorrow. Don’t book it for three days. Book it for seven days. That’s the minimum time to study effectively between attempts.
Once the appointment is scheduled, go to your score report and identify your lowest-scoring domain. Spend the next 4 hours studying only that domain on Microsoft Learn.
The DP-900 is passable. Thousands pass it every month. You’re 20-30 points away. That’s one domain of focus, three solid practice tests, and seven days of real studying.
You’ve got this. Start now.
