SC-100 Design solutions that align with security best practices and priorities Practice Test 11 — 15 Questions

Question 1

Your organization is planning to deploy Microsoft Purview Information Protection to classify and protect sensitive data. You need to design a solution that automatically applies sensitivity labels to documents containing personally identifiable information (PII) when they are uploaded to SharePoint Online. Which configuration should you use?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Create an auto-labeling policy that uses a sensitive info type for PII. Microsoft Purview auto-labeling policies can automatically apply sensitivity labels to documents containing PII when they are uploaded to SharePoint Online. By configuring a policy with a sensitive info type (e.g., U.S. Social Security Number) as the condition, the service scans content at rest and applies the label without user intervention, meeting the requirement for automatic classification.

Answer

Set a default sensitivity label for the SharePoint site

Answer

Use trainable classifiers to identify PII and apply labels

Answer

Configure a manual labeling policy that prompts users to classify documents

Question 2

Your organization has a hybrid identity environment with Microsoft Entra ID and on-premises Active Directory. You need to design a solution that ensures all user authentication requests are evaluated by Conditional Access policies before granting access to cloud apps. However, some legacy apps still require basic authentication. What should you recommend?

Accepted Answer

Enable authentication policies in Microsoft Entra ID to block legacy authentication. Enabling authentication policies in Microsoft Entra ID to block legacy authentication ensures that all user authentication requests are evaluated by Conditional Access policies before granting access to cloud apps. Legacy authentication protocols (e.g., POP3, IMAP, SMTP, basic auth) bypass modern authentication and Conditional Access, so blocking them forces clients to use modern protocols (OAuth 2.0, OpenID Connect) that are subject to Conditional Access evaluation. This directly addresses the requirement while allowing legacy apps to be updated or replaced over time.

Answer

Configure Active Directory Federation Services (AD FS) as the identity provider

Answer

Deploy Microsoft Entra Application Proxy for all legacy apps

Answer

Enable pass-through authentication (PTA) to forward authentication requests

Question 3

Your organization is implementing a secure DevOps pipeline for a critical application. You need to design a solution that scans container images for vulnerabilities before they are deployed to production. Which Azure service should you integrate into the pipeline?

Accepted Answer

Microsoft Defender for Cloud. Microsoft Defender for Cloud (formerly Azure Security Center) provides integrated vulnerability assessment for container images stored in Azure Container Registry (ACR). When integrated into a DevOps pipeline, Defender for Cloud can scan images on push or on demand, using the Qualys scanner to detect CVEs and generate detailed security reports. This allows the pipeline to block or flag vulnerable images before they reach production, directly addressing the requirement for pre-deployment vulnerability scanning.

Question 5

Your organization is implementing Microsoft Intune for mobile device management. You need to design a solution that ensures corporate data on mobile devices is protected if the device is lost or stolen. Which TWO actions should you configure?

Accepted Answer

Configure a compliance policy that requires device encryption. A compliance policy requiring device encryption ensures that if a device is lost or stolen, the data stored on it is unreadable without the decryption key. Intune compliance policies evaluate encryption status (e.g., BitLocker on Windows, FileVault on macOS, or device encryption on iOS/Android) and mark noncompliant devices for conditional access blocking, preventing unauthorized access to corporate data.

Answer

Enforce a minimum PIN length on devices

Answer

Require app protection policies (MAM) for all apps

Answer

Enable jailbreak detection in a device compliance policy

Question 6

A company is adopting Microsoft Purview for data security. They need to prevent users from sharing sensitive data like credit card numbers via email. Which feature should you configure?

Accepted Answer

Data Loss Prevention (DLP) policy. Data Loss Prevention (DLP) policies in Microsoft Purview are specifically designed to detect and prevent the accidental or intentional sharing of sensitive information, such as credit card numbers, through email and other channels. By configuring a DLP policy with a rule that scans for credit card number patterns (using predefined or custom sensitive info types), the system can block, quarantine, or notify users when such data is sent via Exchange Online. This directly addresses the requirement to prevent sharing sensitive data via email.

Answer

Audit log search

Answer

Insider Risk Management policy

Answer

Sensitivity labels

Question 7

Your organization uses Microsoft Sentinel for SIEM. You need to ensure that security incidents are automatically responded to without human intervention for known false positives. What should you implement?

Accepted Answer

An automation rule with incident closure action. Automation rules in Microsoft Sentinel can be configured to automatically close incidents when specific conditions are met, such as when an incident is identified as a known false positive. This eliminates the need for human intervention by triggering an incident closure action based on predefined criteria, directly addressing the requirement for automated response to false positives.

Question 13

You are a security architect for a large financial services company. The company has a hybrid identity environment with on-premises Active Directory synchronized to Microsoft Entra ID using Microsoft Entra Connect. They use Microsoft 365 E5 licenses and have deployed Microsoft Defender for Cloud, Microsoft Defender for Identity, Microsoft Sentinel, and Microsoft Purview. The company has recently suffered a ransomware attack where an attacker gained access via a compromised service account that had permanent Global Administrator privileges. The attacker then used the account to create a backdoor user and exfiltrate sensitive data from SharePoint Online. After the incident, the CISO mandates a Zero Trust security transformation with the following requirements: 
1. Eliminate standing privileged access for all cloud admins.
2. Require phishing-resistant authentication for all privileged roles.
3. Ensure that all sensitive data in SharePoint Online is automatically classified and protected.
4. Enable detection of lateral movement using anomalous behavior analytics. Which combination of actions should you recommend?

Accepted Answer

Implement Privileged Identity Management (PIM) for Global Administrator roles, configure Authentication Strengths to require FIDO2, create auto-labeling policies for credit card numbers, and enable Defender for Identity lateral movement path detection.. It directly addresses all four CISO requirements: Privileged Identity Management (PIM) eliminates standing Global Administrator privileges by requiring just-in-time activation; Authentication Strengths with FIDO2 enforces phishing-resistant authentication for privileged roles; auto-labeling policies in Microsoft Purview automatically classify and protect sensitive data like credit card numbers in SharePoint Online; and Defender for Identity lateral movement path detection uses behavioral analytics to detect anomalous lateral movement, fulfilling the detection requirement.

Answer

Deploy Microsoft Entra Identity Protection for all users, configure Azure AD Conditional Access with MFA, use Microsoft Purview Information Protection with manual labeling, and enable Microsoft Sentinel analytics for lateral movement.

Answer

Configure Conditional Access to require MFA for admins, enable Microsoft Purview DLP for SharePoint, deploy Defender for Cloud Apps, and use Identity Protection for user risk.

Answer

Remove all permanent admin roles and use just-in-time access via PIM, enforce MFA via Conditional Access, apply sensitivity labels via Microsoft Purview Data Map, and use Microsoft Defender for Cloud for network security groups.

Question 14

Your organization is adopting Microsoft Entra ID as the identity provider for all SaaS applications. The security team wants to enforce multifactor authentication (MFA) for all users accessing these applications. Which approach aligns with security best practices and minimizes user friction?

Accepted Answer

Create a Conditional Access policy requiring MFA for all cloud apps, excluding trusted locations and devices.. Conditional Access policies allow granular, risk-based MFA enforcement that excludes trusted locations (e.g., corporate offices) and trusted devices (e.g., compliant or hybrid-joined devices). This aligns with the Zero Trust principle of 'verify explicitly' while minimizing user friction by not prompting for MFA when the user is already in a trusted context. Security defaults (Option C) enforce MFA for all users but lack the ability to exclude trusted locations or devices, which can cause unnecessary friction.

Answer

Enable per-user MFA for all users in Microsoft Entra ID.

Answer

Disable MFA and rely on strong password policies.

Answer

Enable Microsoft Entra ID Security defaults.

Question 15

A company uses Microsoft Defender for Cloud to assess the security posture of their Azure subscriptions. They want to ensure that all virtual machines have the Log Analytics agent installed and that missing system updates are remediated automatically. Which two recommendations should be enabled in a single policy initiative?

Accepted Answer

Enable the Microsoft Defender for Cloud 'System Updates' and 'Log Analytics agent' recommendations via a built-in initiative.. Microsoft Defender for Cloud includes a built-in policy initiative (the 'ASC Default' initiative) that contains both the 'System Updates' and 'Log Analytics agent' recommendations. Enabling this single initiative automatically assigns both requirements to the selected scope, ensuring that missing system updates are remediated and the Log Analytics agent is installed on all virtual machines without needing custom policies or separate assignments.

Answer

Assign two separate Azure Policy initiatives, one for each requirement.

Answer

Create a custom Azure Policy initiative that combines the two requirements.

Answer

Use Azure Blueprints to assign the policies to all subscriptions.
