SC-401 Exam Dumps - Microsoft Certified: Information Security Administrator Associate Questions and Answers

Step 1 – Review the configuration

Sensitivity label name: Contoso Confidential

Scope: Files and emails

Access control:

Encrypts documents/emails.

Permissions assigned to AuthenticatedUsers with Co-Author rights.

Offline access allowed only for 7 days.

Auto-labeling = None (not configured).

Content marking: Footer applied.

Step 2 – Analyze each statement

Statement 1: If a user account is disabled, the user will be immediately prevented from opening a file protected by Contoso Confidential.

Sensitivity labels with encryption enforce Azure AD authentication every time a user tries to access a file.

If the account is disabled in Azure AD, access is blocked immediately.

Answer: Yes

Statement 2: Guest users will be able to open documents protected by Contoso Confidential.

Access control was configured only for AuthenticatedUsers (internal users).

Guest or external users are not included in this group.

Therefore, guest users cannot open the protected documents.

Answer: No

Statement 3: Contoso Confidential will be applied automatically to the files stored in Microsoft SharePoint Online.

Auto-labeling for files and emails = None.

That means labeling must be applied manually by users, not automatically.

Answer: No

Final Verified Answers

If a user account is disabled, the user will be immediately prevented from opening a file protected by Contoso Confidential → Yes

Guest users will be able to open documents protected by Contoso Confidential → No

Contoso Confidential will be applied automatically to the files stored in Microsoft SharePoint Online → No

The issue: Users cannot upload documents with U.S. passport numbers to a legitimate travel management website because Endpoint DLP is blocking it.

Solution: Configure Service domains in Endpoint DLP → this allows defining specific trusted domains where uploads of sensitive information are permitted while still blocking uploads to other, non-approved domains.

Why not others?

Unallowed browsers: Restricts/blocklists browsers, not the issue here.

File path exclusions: Excludes local folders/paths from monitoring, irrelevant to web uploads.

Unallowed apps: Restricts desktop apps, not browser-based sites.

Microsoft Endpoint DLP relies on Microsoft Defender for Endpoint (MDE) for its enforcement.

Onboarding Windows 10/11 devices to Defender for Endpoint ensures the Endpoint DLP policies can be applied, including monitoring and protecting content across apps and browsers.

Step 1 – Requirement

You need to configure a mail flow rule in Exchange Online to apply a Microsoft Purview Advanced Message Encryption (OME) branding template named OME1.

Step 2 – Mail Flow Rule Conditions

In Exchange Online, to trigger encryption based on sensitivity labels (classifications):

You use the condition "Apply this rule if: The sender … Includes the classification".

This lets the rule detect when the sender applies a particular sensitivity label (classification) to the email.

Step 3 – Mail Flow Rule Action

To apply a custom branding template (such as OME1), you configure the action:

"Modify the message security".

This is the action that allows applying encryption and assigning a specific OME template for branding.

Custom Data Access Governance (DAG) data assessment scans in Microsoft Purview can be run on selected SharePoint Online or OneDrive locations to check for oversharing and exposure. Each custom assessment scan supports up to 200,000 items per location. This cap is documented in Microsoft’s guidance for custom data access governance assessments.

To implement Microsoft Purview Data Lifecycle Management for SharePoint Online (Site1), you need to create a retention label first. Retention labels define how long content should be retained or deleted based on compliance requirements. Once a retention label is created, it can be manually or automatically applied to content in SharePoint Online, Exchange, OneDrive, and Teams. After creating a retention label, you can configure label policies to apply them to Site1 and other locations.

Trainable classifiers in Microsoft Purview learn from sample documents. When the initial results are unsatisfactory, retraining is done by reviewing and reclassifying items through Content explorer under the Data classification section of the Purview compliance portal. This allows you to give feedback by marking documents as “relevant” or “not relevant” to improve classifier accuracy.

The other options do not support retraining:

Labels from Information protection → Used to configure and manage sensitivity labels, not train classifiers.

Labels from Information governance → Used for retention labels, not classifiers.

Content search → Used for eDiscovery and searching content, not classifier training.

Step 1 – Requirement

You want to create a custom sensitive info type named Sensitive1.

This SIT will be created from a document fingerprint of Template1.docx.

You then want to use Sensitive1 in DLP policies.

Step 2 – Where do you create custom Sensitive Info Types?

Custom SITs (including document fingerprinting) can only be created in the Microsoft Purview compliance portal.

They cannot be created in the Exchange admin center, SharePoint admin center, or directly in PowerShell.

Answer for creation: The Microsoft Purview portal

Activity Explorer logs a DLP rule match event each time any DLP rule condition is met on a file.

File1 matches Rule11 and Rule12 → 2 events

File2 matches Rule21 and Rule22 → 2 events

File3 matches Rule11 and Rule22 → 2 events

Total events in Activity Explorer = 2 + 2 + 2 = 6.

Microsoft notes that Activity explorer shows granular DLP activities such as policy rule matches per item.

The DLP incidents report aggregates by policy match per item, not by each rule in that policy. Multiple rules from the same policy on the same item count as one incident; if different policies match the same item, each policy creates its own incident.

File1: Rules from DLP1 only → 1 incident

File2: Rules from DLP2 only → 1 incident

File3: One rule from DLP1 and one from DLP2 → 2 incidents

Total incidents = 1 + 1 + 2 = 4.

The scenario is about retaining audit logs for User1 for 10 years in Microsoft 365. Admin1 is responsible for managing audit retention policies, but the requirement specifically applies to User1’s audit logs.

Key points:

Microsoft 365 E5 includes Audit (Premium) by default. This provides access to advanced auditing features and retention up to 1 year.

To retain audit logs for longer than 1 year (such as 10 years), Microsoft requires the 10-year Audit Log Retention Add-on license.

This license must be assigned to the user whose activities need to be retained (User1), not the administrator (Admin1).

Admin1 only needs permissions to configure and manage retention policies, but the actual long-term retention is tied to the licensed users’ activity.

Why other options are incorrect:

A. Assign a Microsoft Purview Audit (Premium) add-on license to User1: Not needed because E5 already includes Audit (Premium).

B. Assign a 10-year audit log retention add-on license to Admin1: Incorrect because Admin1 is not the user whose logs must be retained; the license applies to the user being audited, not the admin.

D. Assign a Microsoft Purview Audit (Premium) add-on license to Admin1: Again, unnecessary because E5 already includes Audit (Premium), and Admin1’s license does not affect User1’s log retention.
