SC-100 Quick Quiz — 10 Questions

Question 1

A company needs to design a secure DevOps pipeline using GitHub Actions and Microsoft Defender for Cloud. They want to scan infrastructure-as-code (IaC) templates for misconfigurations before deployment. What should they integrate?

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

Accepted Answer

Microsoft Defender for Cloud Infrastructure as Code scanning. Microsoft Defender for Cloud includes a native Infrastructure as Code (IaC) scanning capability that integrates directly with GitHub Actions. This feature automatically analyzes IaC templates (such as ARM, Bicep, Terraform, and CloudFormation) for security misconfigurations during the CI/CD pipeline, providing pre-deployment guardrails. By failing the pipeline on critical findings, it ensures only compliant infrastructure is deployed, aligning with the secure DevOps principle of shifting security left.

Answer

Microsoft Purview Compliance Manager

Answer

Microsoft Sentinel

Answer

Microsoft Defender for Cloud Apps

Question 2

Your organization is migrating to Microsoft 365 and wants to implement a data classification strategy. The compliance team needs to automatically detect and label documents containing personal data (e.g., Social Security numbers) in SharePoint Online. Which Microsoft Purview solution should you use?

Accepted Answer

Auto-labeling policies. Auto-labeling policies in Microsoft Purview are designed to automatically detect sensitive data types (e.g., Social Security numbers) using built-in or custom sensitive information types and apply sensitivity labels to documents in SharePoint Online. This meets the requirement for automatic detection and labeling without user intervention, as the compliance team needs.

Answer

Records Management

Answer

eDiscovery

Answer

Data Loss Prevention policies

Question 3

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?

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 4

Your company is migrating on-premises Active Directory to Microsoft Entra ID. The security team requires that users must use passwordless authentication methods for all sign-ins. Which Microsoft Entra ID feature should you enable to support passwordless authentication?

Accepted Answer

Microsoft Entra ID passwordless authentication methods. Microsoft Entra ID passwordless authentication methods (such as Windows Hello for Business, FIDO2 security keys, and Microsoft Authenticator) are the native features designed to eliminate passwords entirely. These methods satisfy the security team's requirement by enabling users to sign in without a password, using biometrics or cryptographic keys instead.

Answer

Password hash synchronization

Answer

Seamless Single Sign-On (Seamless SSO)

Answer

Pass-through authentication

Question 5

A company is designing a data security strategy using Microsoft Purview. They need to identify sensitive data across their data estate, including on-premises SQL Server, Azure SQL Database, and Amazon S3. Which THREE components should they use? (Choose three.)

Accepted Answer

Microsoft Purview Data Estate Insights. Microsoft Purview Data Estate Insights provides visibility into data estate health and security posture, including sensitive data discovery across on-premises SQL Server, Azure SQL Database, and Amazon S3. It aggregates scan results and offers dashboards to identify where sensitive data resides, enabling targeted classification and protection actions.

Answer

Microsoft Purview External Identities

Answer

Microsoft Purview Compliance Manager

Question 6

Your organization uses Microsoft Purview Information Protection to label sensitive emails. You need to ensure that labels are applied automatically based on content. Which THREE methods can you use?

Accepted Answer

Sensitive information types. Sensitive information types (C) are predefined or custom patterns that detect sensitive data such as credit card numbers or social security numbers, enabling automatic label application. Auto-labeling policies in Microsoft Purview (D) apply labels automatically to emails and files based on conditions like sensitive information types or trainable classifiers. Trainable classifiers (E) use machine learning to identify content patterns and automatically apply labels without requiring explicit pattern definitions.

Answer

Manual labeling by users

Answer

File plan (for records management)

Question 7

Your organization uses Microsoft Sentinel and wants to automatically respond to high-severity incidents. Which feature should you configure?

Accepted Answer

Configure an automation rule to run a playbook automatically. Automation rules in Microsoft Sentinel allow you to define automated responses that trigger when an incident is created or updated, including running playbooks (Azure Logic Apps workflows) automatically. This is the correct approach for automatically responding to high-severity incidents because it eliminates manual intervention and ensures consistent, immediate action based on incident properties like severity.

Answer

Create a playbook and run it manually for each incident

Answer

Set up an analytics rule with automatic response

Answer

Use a workbook to trigger a playbook

Question 8

Your organization needs to enforce multi-factor authentication (MFA) for all users accessing sensitive applications. You plan to use Microsoft Entra ID Conditional Access. Which grant control should you configure?

Accepted Answer

Require multi-factor authentication. The question specifies a requirement to enforce MFA for all users accessing sensitive applications. In Microsoft Entra ID Conditional Access, the 'Require multi-factor authentication' grant control directly enforces Azure AD MFA (e.g., via Microsoft Authenticator, OATH tokens, or SMS) as the primary authentication method. This is the simplest and most direct control to meet the stated goal of requiring MFA, without adding additional constraints like device compliance or authentication strength levels.

Answer

Require authentication strength (e.g., phishing-resistant MFA)

Answer

Require device to be marked as compliant

Answer

Use app enforced restrictions

Question 9

A company plans to implement Microsoft Purview to enforce data loss prevention (DLP) policies. They need to prevent users from sharing credit card numbers via email. What should they configure?

Accepted Answer

Create a DLP policy that detects and blocks credit card numbers in Exchange Online. Microsoft Purview Data Loss Prevention (DLP) policies can be configured to detect sensitive data types, such as credit card numbers, in Exchange Online emails. When a DLP policy is created with a rule that identifies credit card numbers and blocks the email from being sent, it directly prevents users from sharing that data via email. This is the native mechanism for enforcing DLP on email traffic in Microsoft 365.

Answer

Create a sensitivity label and apply it to emails

Answer

Enable communication compliance policies

Answer

Configure a retention policy for email

Question 10

Your company uses Microsoft Defender for Cloud Apps and wants to prevent users from uploading sensitive files to personal cloud storage apps. What should you configure?

Accepted Answer

Session policy. Session policy in Microsoft Defender for Cloud Apps allows real-time monitoring and control of user activities based on app and content inspection. By configuring a session policy, you can block or restrict uploads of sensitive files to personal cloud storage apps like Dropbox or Google Drive during the user's session, leveraging reverse proxy capabilities to inspect and intervene in traffic.

Answer

Activity policy

Answer

App connector

Answer

File policy
