Do not rely on the practice assessment score alone.
In one widely discussed thread, candidates who scored highly on the free practice assessment found the real exam harder, with more questions about naming the right product for a scenario.

Validates foundational knowledge of security, compliance and identity concepts and Microsoft Entra, security and compliance solutions.
SC-900 tests whether you can describe security, compliance and identity concepts and match Microsoft's products to a business need. Learn what each Entra, Defender, Sentinel and Purview feature is for, then practise choosing the right one for short scenarios.
Example scenario: A company moves its email to a cloud service. Which security tasks stay with the company under the shared responsibility model?
Example scenario: Administrators should get their elevated role only when they need it, with an approval step. Which Entra feature fits?
Example scenario: A security team wants to collect logs from many sources, detect threats and run automated responses. Which Microsoft service is built for this?
Example scenario: Documents marked Confidential must stay encrypted when they are emailed outside the company. Which Purview feature applies the protection?

Choose the best answer from the options, or the stated number of answers when a question asks for more than one.
A company wants to allow sign-in to its apps only from devices that meet its compliance rules. Which Microsoft Entra capability enforces this?
A. Conditional Access sets conditions, such as device compliance, that must be met before access is granted. Privileged Identity Management controls when admin roles are active.
Drag items from a list into the matching places; an item can be used once, more than once or not at all.
Drag each Microsoft service to the task it handles. The tasks are collect and analyse security logs from many sources, protect endpoints from threats, and label and protect sensitive documents.
Collect and analyse security logs → Microsoft Sentinel, protect endpoints → Microsoft Defender for Endpoint, label and protect sensitive documents → Microsoft Purview.
Pick one value from each drop-down list in a block of text or a diagram to complete it.
Select the correct value in each list. Zero Trust treats every request as [verified explicitly / trusted by default], and applies [least privilege access / unrestricted access].
Verified explicitly, and least privilege access. Zero Trust checks every request and limits what each identity can reach.
Sign in to Microsoft Learn with a personal Microsoft account, then schedule SC-900 with Pearson VUE from the exam page. Students and educators can also book through Certiport.
Read the skills list, take the free practice assessment once to see where you stand, then work through one course.
Most candidates spend 15–35 hours. Plan for the low end if you already use Microsoft 365 or Entra; add time for the compliance section and Defender products if they are new to you.
Use one course for coverage. The free Microsoft Learn modules follow the skills list closely.
Learn what each product is for. Many questions describe a need and ask which product or feature meets it. Make a one-line purpose for every product in the skills list.
Take Microsoft's free practice assessment to learn the style, then add a second question bank for more scenario practice.
Choose the checklist for your test-centre or online appointment.
Breaks are allowed, but the clock keeps running and you cannot go back to questions you saw before the break.
In one widely discussed thread, candidates who scored highly on the free practice assessment found the real exam harder, with more questions about naming the right product for a scenario.
One passer who scored 860 found the Purview compliance section their weakest area and advised extra study there.
The same passer built their preparation around John Savill's study cram and official practice questions.
