| Skill area | Official weight | On a 40-question form | On a 50-question form | On a 60-question form |
| Describe Azure architecture and services | 35 to 40 percent | 14 to 16 questions | 18 to 20 questions | 21 to 24 questions |
| Describe Azure management and governance | 30 to 35 percent | 12 to 14 questions | 15 to 18 questions | 18 to 21 questions |
| Describe cloud concepts | 25 to 30 percent | 10 to 12 questions | 13 to 15 questions | 15 to 18 questions |
| Total | 90 to 105 percent, since each weight is a range | about 40 questions | about 50 questions | about 60 questions |
These are planning estimates, not published counts. The largest block is Azure architecture and services, at 14 to 24 questions depending on the form. Management and governance is next, at 12 to 21. Cloud concepts is the smallest, at 10 to 18.
How much time do you get per question in the 45-minute exam?
The exam clock runs for 45 minutes. The whole sitting is booked as 65 minutes, which includes the instructions and the agreement screens. Microsoft built a 5-minute break into that time and cut questions to make room. The break is optional. The clock keeps running while you are on break. You cannot return to a question you saw before the break.
- Exam time - 45 minutes of timed questions
- Optional break - 5 minutes built into the 45, with the clock still running
- Microsoft Learn - closed during Fundamentals exams, with no extra time added
Divide the minutes by the number of questions to get your budget. The first figure below uses all 45 minutes. The second assumes you spend a full 5 minutes on a break.
| Exam form | Questions | Seconds per question, no break | Seconds per question, 5-minute break |
| Smallest form | 40 | 67 | 60 |
| Mid form | 50 | 54 | 48 |
| Largest form | 60 | 45 | 40 |
Microsoft Learn also stays closed during a Fundamentals exam, so you cannot look up an answer mid-test.
What happens if you fail the AZ-900?
If you miss the AZ-900 passing score on the first attempt, Microsoft's retake policy sets the rules. Wait 24 hours and you can book again. After that, every attempt needs a 14-day gap. You can take the exam five times in 12 months, and every attempt is paid in full.
That policy turns one weak morning into a calendar problem. It also gives you a plan, because you get 14 days and a report showing where you lost points. Read the skill-area bars and put your revision time into the lowest ones. Our guide to Azure certification cost covers the fees.
Should you book AZ-900 or AWS Cloud Practitioner first?
The Amazon Web Services (AWS) Certified Cloud Practitioner is the other common first cloud credential. It has no prerequisite either. The AWS Cloud Practitioner exam guide lists 65 questions in 90 minutes. Only 50 of them affect the score. The price is $100 in the US, and the pass mark is 700 on a scale of 100 to 1,000.
Two differences matter if cloud is new to you. The AZ-900 runs for half the time. The AWS exam scores 50 of its 65 questions. Its scoring is compensatory, so no section carries a minimum. AWS says up to six months of AWS exposure is expected, but not required.
- Exam length - 45 minutes on the AZ-900, 90 minutes on the AWS exam
- Pass mark - 700 on both, on a 1 to 1,000 scale for Microsoft and 100 to 1,000 for AWS
Choose AZ-900 when the jobs you want ask for Azure. Choose the AWS Cloud Practitioner when they ask for Amazon Web Services (AWS). If you are still unsure which cloud fits, read our guide to the best cloud certifications for career growth. To try the AWS side first, use our AWS Cloud Practitioner practice test samples.
| Criteria | AZ-900 - Microsoft Azure Fundamentals | AWS Certified Cloud Practitioner (CLF-C02) |
| Minimum passing score | 700 | 700 |
| Score scale | 1 to 1,000 | 100 to 1,000 |
| Exam duration | 45 minutes | 90 minutes |
| Seat time | 65 minutes | Not published |
| Total questions | 40 to 60, no published count | 65, made up of 50 scored plus 15 unscored |
| Price in the US | $99 | $100 |
| Scoring model | Scaled and difficulty-adjusted | Compensatory, no section minimum |
What should you do next?
Start with the free Practice Assessment on the exam page and score it under the 45-minute clock. Give your next study block to the skill area with the lowest bar. Put the 14-day rule in your calendar before you book, so a waiting period is planned. The next step after the AZ-900 is covered in our Azure Administrator Associate certification guide.
The AZ-900 passing score target is 700 on a scaled 1 to 1,000 scale, not a percentage of questions right. The published skill weights tell you where the points sit. The retake policy prices a failure in fees and waiting days.
