The SC-401 exam validates your ability to administer information security in Microsoft 365 environments. Designed for IT professionals pursuing the Information Security Administrator Associate credential, this exam tests both foundational knowledge and practical decision-making across key security domains. This page outlines the exam structure, core topics, and study strategies to help you prepare effectively and confidently.
Use this topic map to guide your study for Microsoft SC-401 (Administering Information Security in Microsoft 365) within the Information Security Administrator Associate path.
The SC-401 exam uses multiple question types to assess both conceptual understanding and applied reasoning in real-world security scenarios. Questions progress in difficulty, requiring you to move beyond memorization to demonstrate practical judgment.
Questions are designed to reflect actual job tasks, ensuring your preparation translates directly to on-the-job capability.
Effective preparation requires mapping exam topics to a structured study schedule and reinforcing concepts through practice. Dedicate time each week to one or two core topics, hands-on configuration, and scenario review to build both depth and speed.

Data loss prevention and retention, along with risk and alert management, typically account for a larger portion of the exam. However, information protection is foundational and appears throughout multiple question types. Balance your study time across all three domains rather than skipping any single area.
Protection policies classify and encrypt sensitive data, DLP policies then monitor and prevent unauthorized movement of that data, and risk management tools alert you when violations or suspicious activities occur. Understanding these as an integrated workflow helps you answer scenario questions correctly and design effective security postures on the job.
Ideally, you should have 1-2 years of experience administering Microsoft 365 or similar cloud security environments. If you lack hands-on exposure, prioritize labs and simulation-style practice questions to build familiarity with admin interfaces and policy configuration. Many candidates find that working through practice tests reveals gaps that studying theory alone does not.
Confusing DLP policy actions with protection label settings, misunderstanding alert severity levels, and overlooking compliance-specific requirements are frequent errors. Carefully read scenario details for context clues about regulatory requirements or business constraints that influence the correct answer. Take time to review explanation text for questions you guess on, even if you answer correctly.
Spend 3-4 days reviewing weak topic areas using practice questions and explanations, then take one full-length timed practice test 2-3 days before your exam date. Use your test results to identify any remaining gaps, then do a final review of key definitions and policy decision trees. Avoid cramming new material in the last 24 hours; instead, rest and mentally rehearse your test-taking strategy.
You have a Microsoft J65 subscription linked to a Microsoft Entra tenant that contains a user named User1. You need to grant User1 permission to search Microsoft 365 audit logs. The solution must use the principle of least privilege. Which role should you assign to User1?
You are configuring a data loss prevention (DLP) policy to report when credit card data is found on a Microsoft Entra joined Windows device.
You plan to use information from the policy to restrict the ability to copy the sensitive data to the clipboard.
What should you configure in the policy advanced DLP rule?
You are creating a data loss prevention (DLP) policy that will apply to all available locations except Fabric and Power BI workspaces.
You configure an advanced DLP rule in the policy.
Which type of condition can you use in the rule?
When configuring an advanced DLP rule in Microsoft Purview Data Loss Prevention (DLP), you can use a Sensitive Information Type (SIT) condition to detect and classify specific types of sensitive data, such as credit card numbers, Social Security numbers, or custom sensitive data patterns. This allows you to apply protection and trigger actions based on the identified content.
You need to meet the retention requirement for the users' Microsoft 365 data.
What is the minimum number of retention policies required to achieve the goal?
The requirement states that all Microsoft 365 data for users must be retained for at least one year. In Microsoft 365, retention policies must be configured for each type of data storage.
Step 1: Identifying Where Data is Stored
From the case study, users store data in the following locations:
SharePoint Online sites
OneDrive accounts
Exchange email
Exchange public folders
Teams chats
Teams channel messages
Since these locations fall under two broad categories:
Microsoft Exchange data (Emails, Public folders)
SharePoint, OneDrive, and Teams data
Step 2: Required Retention Policies
1. A single retention policy can cover:
SharePoint Online
OneDrive
Microsoft Teams
2. A second retention policy is required for:
Exchange (Emails & Public Folders)
Thus, the minimum number of retention policies required to meet the requirement is 2.
Microsoft 365 retention policies can be applied broadly across multiple services with just two policies:
One for Exchange & Public Folders
One for SharePoint, OneDrive, and Teams
There's no need for separate policies for each individual workload unless different retention durations are required, which is not stated in the requirement.
You have a Microsoft 365 E5 subscription that uses retention label policies.
You need to identify all the changes made to retention labels during the last 30 days.
