SC-900 Mock Exam 75 — 25 Questions

Question 1

A large enterprise is concerned about insider threats. The compliance team needs to detect and investigate potential data theft scenarios, such as when employees nearing their resignation date suddenly copy large amounts of sensitive data to USB drives or email confidential files to personal accounts. They require a solution that uses machine learning to identify risky activities and create alerts for investigation. Which Microsoft Purview solution should they deploy?

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

Accepted Answer

Insider Risk Management. Insider Risk Management is the correct solution because it uses machine learning to correlate signals from user activities (e.g., copying files to USB, emailing to personal accounts) with contextual indicators like resignation dates, enabling detection of potential data theft scenarios. It provides built-in alerting and investigation workflows specifically designed for insider threat use cases, unlike the other options which focus on retention, auditing, or compliance posture.

Question 2

A company wants to create a sensitivity label called 'Highly Confidential' in Microsoft 365. When applied to a document, the label should automatically encrypt the document and restrict access to employees in the finance department only. Which Microsoft Purview solution should the administrator use to configure this label?

Accepted Answer

Microsoft Purview Information Protection. Microsoft Purview Information Protection is the correct solution because it provides the ability to create and configure sensitivity labels that enforce protection actions such as encryption and access restrictions.

Question 3

A company has a hybrid identity environment with Active Directory synchronizing to Microsoft Entra ID. They want users to be able to reset their own on-premises passwords via the cloud SSPR portal. What is the minimum license required for this capability?

Accepted Answer

Microsoft Entra ID P1. Microsoft Entra ID P1 is the minimum license required for password writeback, which enables users to reset their on-premises Active Directory passwords via the cloud SSPR portal. This feature requires Microsoft Entra ID P1 or higher because it involves synchronizing password changes back to on-premises AD using Microsoft Entra Connect.

Answer

Microsoft Entra ID Free

Answer

Microsoft Entra ID P2

Answer

Microsoft 365 Business Basic

Question 4

Refer to the exhibit. An administrator deploys this Azure Resource Manager template. Which TWO of the following statements are true?

Accepted Answer

The policy assignment audits whether SQL Database transparent data encryption is enabled.. The policy definition ID corresponds to 'Audit if SQL Database encryption is not enabled'. The effect is 'AuditIfNotExists', so it audits but does not enforce. The assignment is at subscription/management group scope, not resource group. It does not deploy a resource but assigns a policy.

Answer

The template creates a resource group if it does not exist.

Answer

The policy assignment enforces encryption on existing SQL databases.

Answer

The template deploys a new SQL database.

Question 5

A company with Microsoft 365 wants employees to access corporate applications from their personal Android and iOS devices. The security team requires that these devices be enrolled in mobile device management (MDM) for compliance policies, and that company data can be selectively wiped from the device without affecting personal data. Which Microsoft Entra device identity type should they configure for these personal devices?

Accepted Answer

Microsoft Entra registered. Microsoft Entra registered is the correct device identity type for personal (BYOD) devices because it supports enrollment in MDM for compliance policies and enables selective wipe of company data without affecting personal data. This identity type registers the device with Entra ID without requiring organizational ownership, allowing users to access corporate applications while maintaining personal data separation.

Question 14

A company uses Microsoft 365 and wants to protect its users from clicking malicious links in phishing emails. The security team needs a solution that rewrites URLs in email messages to check the link at the time of click, and blocks access if the link is malicious. Which Microsoft security solution should they use?

Accepted Answer

Microsoft Defender for Office 365. Microsoft Defender for Office 365 includes Safe Links, a feature specifically designed to protect users from malicious URLs in email messages. Safe Links rewrites URLs at the time of delivery, and when a user clicks a link, it checks the destination in real time against threat intelligence; if the link is malicious, access is blocked. This directly matches the requirement to rewrite URLs and perform click-time verification.

Question 15

Refer to the exhibit. You are configuring a sensitivity label in Microsoft Purview. The label is set to automatically apply when credit card numbers are detected. However, users report that the label is not being applied to documents containing credit card numbers. What is the most likely cause?

Accepted Answer

The label is not published to a label policy. The auto-labeling rule requires a condition, but the label may not be published to users. However, the exhibit shows no policy assignment. The most likely cause is that the label is not published to a label policy (option B). Option A is incorrect because encryption is configured. Option C is incorrect because the condition is valid. Option D is incorrect because user permissions are defined.

Answer

The encryption is misconfigured

Answer

The auto-labeling condition is incorrect

Answer

The user permissions are missing
