SC-900 Practice Exam 4 — 20 Questions

Question 1

Your company uses Microsoft Defender for Endpoint. You need to configure attack surface reduction (ASR) rules. Which TWO of the following are ASR rules?

Accepted Answer

Block executable content from email client and webmail. ASR rules are designed to block common attack vectors by controlling specific behaviors. 'Block executable content from email client and webmail' prevents malicious scripts or executables from running when delivered via email, which is a primary infection vector. Option E is correct because 'Block Office applications from creating child processes' stops attackers from using Office apps (like Word or Excel) to spawn malicious processes (e.g., PowerShell or cmd.exe), a classic technique for code execution.

Answer

Allow only signed executables

Answer

Block inbound connections from the internet

Answer

Block untrusted fonts

Question 2

Which TWO Microsoft Entra features can be used together to enforce risk-based conditional access?

Accepted Answer

Conditional Access. Conditional Access (B) is correct because it is the policy engine that enforces access decisions based on signals, including risk levels. Identity Protection (C) is correct because it detects and calculates user and sign-in risk in real time using machine learning. Together, Identity Protection provides the risk assessment, and Conditional Access enforces the policy (e.g., block or require MFA) based on that risk.

Answer

Entra Verified ID

Answer

Self-Service Password Reset

Answer

Privileged Identity Management

Question 3

Which two scenarios are examples of using Microsoft Entra business-to-business (B2B) collaboration? (Choose two.)

Accepted Answer

A user from a partner organization is invited to access a SharePoint Online site.. Microsoft Entra B2B collaboration allows you to invite external users from partner organizations to access your company's resources, such as a SharePoint Online site. The invited user authenticates using their own home tenant credentials, and a B2B guest user object is created in your directory to represent them.

Answer

An employee uses their Microsoft Entra ID to sign in to a third-party SaaS application.

Answer

Two internal departments share resources within the same tenant.

Answer

Customers use their Facebook accounts to sign in to a company's web application.

Question 4

Which THREE Microsoft Defender XDR components are included in the unified security operations platform? (Select three.)

Accepted Answer

Microsoft Defender for Office 365. Microsoft Defender XDR (Extended Detection and Response) unifies signals from across the Microsoft 365 Defender portal. Microsoft Defender for Office 365 is a core component because it protects email, SharePoint, OneDrive, and Teams from threats like phishing and malware, and its alerts feed directly into the unified XDR incident queue. This integration allows cross-domain correlation with endpoint, identity, and cloud app signals.

Answer

Microsoft Defender for Cloud

Answer

Microsoft Defender for IoT

Question 5

Your organization is implementing Microsoft Purview to govern data across Microsoft 365 and Azure. Which TWO capabilities should you use to discover and classify sensitive data?

Accepted Answer

Microsoft Purview Information Protection. Microsoft Purview Information Protection (A) enables you to discover, classify, and protect sensitive data by applying sensitivity labels and analyzing content via data loss prevention (DLP) policies. Microsoft Purview Data Map (B) provides automated scanning and classification of data assets across Azure and Microsoft 365, building a unified map of sensitive data locations. Together, they fulfill the discovery and classification requirements.

Answer

Microsoft Purview eDiscovery

Answer

Microsoft Purview Audit

Answer

Microsoft Purview Data Lifecycle Management

Question 6

Which THREE of the following are capabilities provided by Microsoft Entra ID Protection? (Select three.)

Accepted Answer

Automated investigation and remediation of identity risks. Microsoft Entra ID Protection includes automated investigation and remediation capabilities that respond to detected identity risks. When a risk is identified, such as a compromised user account, the service can automatically trigger actions like requiring a password reset or blocking sign-in attempts, reducing the need for manual intervention.

Answer

Passwordless authentication options

Answer

Device compliance assessment

Question 7

Refer to the exhibit. A security analyst is reviewing a Microsoft Defender XDR alert. Which two tactics identified are most relevant? (This is a multiple-choice question asking which two tactics are shown, but the format is single answer. We need to adjust: The question asks: 'Which two tactics are identified?' The correct answer is the option listing both 'InitialAccess and LateralMovement'.)

Accepted Answer

InitialAccess and LateralMovement. The exhibit shows a Microsoft Defender XDR alert indicating that an attacker gained initial access (e.g., via a phishing link or compromised credential) and then moved laterally within the network (e.g., using remote desktop or SMB). These two stages correspond directly to the InitialAccess and LateralMovement tactics in the MITRE ATT&CK framework, which are the most relevant based on the alert details.

Answer

LateralMovement and PrivilegeEscalation

Answer

LateralMovement and Exfiltration

Answer

InitialAccess and Persistence

Question 8

A healthcare organization is implementing Microsoft Purview Data Lifecycle Management to retain medical records for 7 years. Which THREE components must be configured to achieve this retention requirement?

Accepted Answer

Create a retention label policy to publish the label.. A retention label policy is required to publish the retention label so that it can be automatically or manually applied to the medical records. Without publishing the label via a policy, the label itself cannot be assigned to content, and the retention period will not take effect.

Answer

Apply a sensitivity label to classify the records.

Answer

Implement Data Loss Prevention (DLP) policies to prevent data exfiltration.

Question 9

Refer to the exhibit. You run a KQL query in Microsoft Sentinel to investigate ransomware alerts. The query returns: AlertSeverity High: 5, Medium: 3, Low: 2. The security team wants to automate a response for all high-severity ransomware alerts. What should you configure?

Accepted Answer

Create an automation rule that triggers a playbook for high-severity ransomware incidents. Microsoft Sentinel automation rules allow you to define automated responses triggered when incidents are created or updated. By configuring an automation rule with a condition that checks for 'AlertSeverity' equal to 'High' and 'Ransomware' as the related alert, you can invoke a playbook to automatically respond to high-severity ransomware incidents, such as isolating affected machines or blocking indicators of compromise.

Answer

Create an analytics rule for ransomware

Answer

Create a hunting query for ransomware

Answer

Create a workbook to display ransomware alerts

Question 10

A financial services organization must prevent employees in the Research department from communicating via email or Microsoft Teams with employees in the Investment Banking department to avoid conflicts of interest. Additionally, they need to prevent any credit card numbers from being shared in emails sent to external recipients. Which combination of Microsoft Purview solutions should they implement?

Accepted Answer

Information Barriers and Data Loss Prevention. Information Barriers are designed to prevent communication and collaboration between specific groups to avoid conflicts of interest (e.g., research vs. investment banking). Data Loss Prevention (DLP) policies detect and protect sensitive information such as credit card numbers from being shared externally. Communication Compliance focuses on monitoring communications for regulatory compliance but does not block communications, and Insider Risk Management analyzes risky user activities but does not enforce segmentation.

Answer

Communication Compliance and Insider Risk Management

Answer

Information Barriers and Communication Compliance

Answer

Data Lifecycle Management and Data Loss Prevention

Question 11

A security team uses Microsoft Defender XDR to respond to incidents. Which THREE components are part of Microsoft Defender XDR?

Accepted Answer

Microsoft Defender for Office 365. Microsoft Defender XDR is a unified extended detection and response platform that natively integrates signals from Microsoft Defender for Office 365 (email and collaboration protection), Microsoft Defender for Endpoint (endpoint detection and response), and Microsoft Defender for Identity (on-premises identity threat detection). These three components share telemetry and automate incident correlation across domains, which is the core purpose of Defender XDR.

Answer

Microsoft Sentinel

Answer

Microsoft Intune

Question 12

Your organization is using Microsoft Sentinel as a SIEM. You want to automatically respond to a high-severity incident by opening a ticket in ServiceNow and notifying the security team via email. What should you create?

Accepted Answer

An automation rule. Automation rules in Microsoft Sentinel can be configured to trigger automated responses when an incident is created, such as running a playbook (a Logic App) that opens a ticket in ServiceNow and sends an email notification. Option B is wrong because workbooks are for visualization and reporting, not automation. Option C is wrong because analytics rules generate alerts/incidents based on data queries, but they do not directly perform response actions; instead, automation rules handle the response. Option D is wrong because watchlists are collections of data for correlation and enrichment, not for automated response.

Answer

A workbook

Answer

An analytics rule

Answer

A watchlist

Question 13

An organization adopts a security model that requires explicit verification of every access request, uses least privilege principles, and assumes that a breach has already occurred. Which security model does this describe?

Accepted Answer

Zero Trust. Zero Trust is the correct answer because the model explicitly requires verification of every access request, enforces least privilege, and assumes breach. This aligns with the core Zero Trust principles of 'never trust, always verify,' continuous validation, and micro-segmentation, as opposed to traditional perimeter-based models that implicitly trust internal traffic.

Answer

Perimeter-based security

Answer

Defense in depth

Answer

Shared responsibility

Question 14

As a compliance administrator for Contoso Ltd., you are responsible for implementing Microsoft Purview solutions to meet regulatory requirements. The organization operates in the healthcare sector and handles Protected Health Information (PHI). Your key objectives are: (1) Automatically detect PHI in documents stored in SharePoint Online and OneDrive for Business using built-in sensitive information types. (2) Apply a 'Highly Confidential - PHI' sensitivity label that encrypts the content and adds a custom header. (3) Ensure that the label is automatically applied when PHI is detected, with a policy that allows users to override the label with justification. (4) Audit all label application activities for compliance reporting. (5) Retain documents containing PHI for a minimum of 7 years. You have access to Microsoft Purview compliance portal. Which action should you take FIRST to achieve these objectives?

Accepted Answer

Create a sensitivity label named 'Highly Confidential - PHI' with encryption and header, and publish it to users and groups.. The first step is to create the sensitivity label with the required encryption and header settings and publish it so that it can be used in auto-labeling policies. Auto-labeling policies can then be configured to apply the label based on sensitive info types, with user override. Retention labels and policies are separate and can be configured later. Audit is enabled by default but should be verified. Therefore, option C is the correct first action.

Answer

Create an auto-labeling policy in Microsoft Purview that applies the sensitivity label to documents containing PHI.

Answer

Enable auditing in Microsoft Purview by turning on Audit logging.

Answer

Create a retention label and policy to retain documents containing PHI for 7 years.

Question 15

Your organization must ensure that financial reports are protected with encryption and cannot be forwarded. Which two Microsoft Purview features should you combine?

Accepted Answer

Sensitivity labels with encryption and Data Loss Prevention. Sensitivity labels with encryption allow you to apply persistent encryption to financial reports, ensuring they remain protected even when shared. Data Loss Prevention (DLP) policies can then block or warn users from forwarding these encrypted reports via email or other channels, providing a combined solution for encryption and forwarding prevention.

Answer

Data Lifecycle Management and Data Loss Prevention

Answer

Retention policies and Records Management

Answer

Information Barriers and Communication Compliance

Answer

eDiscovery (Premium) and Audit (Standard)

Question 16

Your organization uses Microsoft Purview to enforce retention policies. You need to retain all documents in a specific SharePoint site for 5 years after they are created, and then delete them permanently. What should you configure?

Accepted Answer

A retention policy set to retain for 5 years and then delete. A retention policy scoped to a SharePoint site can be configured to retain items for 5 years after creation and then delete them permanently. This applies automatically to all content in the site without requiring manual action or labels. Option A is incorrect because DLP policies are for preventing data loss, not retention. Option C is incorrect because a retention label is applied per item and requires explicit assignment or auto-application rules, whereas a policy applies broadly to a location. Option D is incorrect because sensitivity labels are for classification and protection, not retention.

Answer

A DLP policy with a retention rule

Answer

A retention label set to retain for 5 years and then delete

Answer

A sensitivity label with a retention setting

Question 17

Your organization is implementing Microsoft Purview to manage data compliance. They need to automatically detect and protect credit card numbers in emails and documents. Which Microsoft Purview feature should they configure?

Accepted Answer

Data Loss Prevention (DLP). Data Loss Prevention (DLP) policies in Microsoft Purview can automatically detect sensitive information like credit card numbers and apply protective actions, such as blocking or encrypting the content. Information Protection refers to sensitivity labels and encryption, but DLP is the feature that uses policies to detect and protect data in transit and at rest. Data Lifecycle Management handles retention and deletion. Insider Risk Management focuses on user behavior.

Answer

Data Lifecycle Management

Answer

Insider Risk Management

Answer

Information Protection

Question 18

Your organization uses Microsoft Entra ID. A user reports that they are unable to access any Microsoft 365 services because they forgot their password. Which self-service tool should they use?

Accepted Answer

Self-Service Password Reset (SSPR). Self-Service Password Reset (SSPR) allows users to reset their own passwords without administrator intervention. Option B, the Password reset admin portal, is intended for administrators to reset passwords for users, not for self-service. Option C, Identity Protection, is a feature that detects and responds to identity-based risks, not for password resets. Option D, Privileged Identity Management, manages and monitors privileged roles and access, not password recovery.

Answer

Password reset admin portal

Answer

Identity Protection

Answer

Privileged Identity Management

Question 19

Which three features are available in Microsoft Entra ID P2 but not in P1? (Choose three.)

Accepted Answer

Access reviews. Access reviews are a Microsoft Entra ID P2 feature that allows administrators to automate periodic reviews of group memberships, application access, and role assignments. This capability is not available in P1, which lacks the automated review workflows and attestation features that P2 provides for governance and compliance.

Answer

Conditional Access policies

Answer

Self-service password reset (SSPR) with writeback

Question 20

An organization uses Microsoft Purview to manage data compliance. They need to automatically detect and protect credit card numbers stored in SharePoint Online. Which Microsoft Purview solution should they implement?

Accepted Answer

Microsoft Purview Data Loss Prevention. Data Loss Prevention (DLP) policies can identify sensitive data like credit card numbers and apply protection actions such as blocking access. Information Protection (sensitivity labels) classifies data but does not automatically detect and protect specific patterns like credit card numbers without DLP integration.
