You have a Microsoft 365 subscription that uses Microsoft Defender for Endpoint Plan 2 and contains 500 Windows devices.
As part of an incident investigation, you identify the following suspected malware files:
• sys
• pdf
• docx
• xlsx
You need to create indicator hashes to block users from downloading the files to the devices.
Which files can you block by using the indicator hashes?
A. File1.sys only
B. File1.sys and File3.docx only
C. File1.sys, File3.docx, and File4.xlsx only
D. File2.pdf, File3.docx, and File4.xlsx only
E. File1.sys, File2.pdf, File3.docx, and File4.xlsx
Show Answer
Correct Answer: A
Explanation: Microsoft Defender for Endpoint file indicators (hash indicators) for blocking downloads are limited to Portable Executable (PE) files. A .sys file is a PE file, whereas .pdf, .docx, and .xlsx are not supported by this indicator type. Therefore, only the .sys file can be blocked using file hash indicators in this scenario.
Question 137
You have a Microsoft 365 E5 subscription that uses Microsoft Defender XDR.
The security team at your company detects command and control (C2) agent traffic on the network. Agents communicate once every 50 hours.
You need to create a Microsoft Defender XDR custom detection rule that will identify compromised devices and establish a pattern of communication. The solution must meet the following requirements:
• Identify all the devices that have communicated during the past 14 days.
• Minimize how long it takes to identify the devices.
To what should you set the detection frequency for the rule?
A. Every 12 hours
B. Every 24 hours
C. Every three hours
D. Every hour
Show Answer
Correct Answer: B
Explanation: Microsoft Defender XDR custom detection rule frequency determines the lookback window. A rule running every 24 hours uses a 30-day lookback, which easily covers the required past 14 days and ensures devices that beacon every 50 hours are included. Shorter frequencies have much shorter lookback windows (48 hours, 12 hours, and 4 hours), which are not sufficient to reliably establish the 50-hour communication pattern across the required 14-day period.
Question 138
You have 500 on-premises Windows 11 devices that use Microsoft Defender for Endpoint.
You enable Network device discovery.
You need to create a hunting query that will identify discovered network devices and return the identity of the onboarded device that discovered each network device.
Which built-in function should you use?
A. SeenBy()
B. DeviceFromIP()
C. next()
D. current_cluster_endpoint()
Show Answer
Correct Answer: A
Explanation: The built-in SeenBy() function in Microsoft Defender XDR advanced hunting returns the onboarded device(s) that observed a discovered network device, making it the correct choice for identifying discovered network devices and the identity of the device that discovered each one.
Question 139

You have a Microsoft 365 E5 subscription that uses Microsoft Defender XDR and contains a Windows device named Device1.
You investigate Device1 for malicious activity and discover a suspicious file named File1.exe. You collect an investigation package from Device1.
You need to review the following forensic data points:
• Is an attacker currently accessing Device1 remotely?
• When was File1.exe first executed?
Which folder in the investigation package should you review for each data point? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: Is an attacker currently accessing Device1 remotely? — Network connections
When was File1.exe first executed? — Prefetch files
Explanation: Active remote access is determined from current network connection data. Windows Prefetch artifacts record executable execution history and can be used to determine the first execution time of File1.exe.
Question 140
You have a Microsoft Sentinel workspace named SW1.
You need to identify which anomaly rules are enabled in SW1.
What should you review in Microsoft Sentinel?
A. Content hub
B. Entity behavior
C. Analytics
D. Settings
Show Answer
Correct Answer: C
Explanation: Anomaly rules in Microsoft Sentinel are managed and viewed from the Analytics page. The Analytics area includes an Anomalies tab that lists anomaly detection rules and indicates whether they are enabled or disabled. Content hub is for solution management, Entity behavior is for investigation context, and Settings does not list enabled anomaly rules.
Question 141
You have an Azure subscription named Sub1 that uses Microsoft Defender for Cloud.
You need to assign the PCI DSS 4.0 initiative to Sub1 and have the initiative displayed in the Defender for Cloud Regulatory compliance dashboard.
From Security policies in the Environment settings, you discover that the option to add more industry and regulatory standards is unavailable.
What should you do first?
A. Configure the Continuous export settings for Log Analytics.
B. Enable the Cloud Security Posture Management (CSPM) plan for the subscription.
C. Configure the Continuous export settings for Azure Event Hubs.
D. Disable the Microsoft Cloud Security Benchmark (MCSB) assignment.
Show Answer
Correct Answer: B
Explanation: The ability to add additional industry and regulatory standards in Microsoft Defender for Cloud depends on the Defender CSPM plan. If the option to add standards such as PCI DSS 4.0 is unavailable under Environment settings > Security policies, the Cloud Security Posture Management (CSPM) plan must first be enabled for the subscription. Continuous export settings and disabling the Microsoft Cloud Security Benchmark assignment do not enable regulatory standards management.
Question 142
You have a Microsoft 365 subscription that uses Microsoft Defender for Endpoint and contains a user named User1 and a Microsoft 365 group named Group1. All users are assigned a Defender for Endpoint Plan 1 license.
You enable Microsoft Defender XDR Unified role-based access control (RBAC) for Endpoints & Vulnerability Management.
You need to ensure that User1 can configure alerts that will send email notifications to Group1. The solution must follow the principle of least privilege.
Which permissions should you assign to User1?
A. Defender Vulnerability Management - Remediation handling
B. Alerts investigation
C. Live response capabilities: Basic
D. Manage security settings
Show Answer
Correct Answer: D
Explanation: To configure Microsoft Defender XDR email notifications for alerts, the required permission is 'Manage security settings'. The 'Alerts investigation' permission allows managing alerts, but configuring global email notification settings is a security configuration task. Following least privilege, assign only the specific 'Manage security settings' permission needed.

You have a Microsoft 365 E5 subscription that uses Microsoft Defender XDR and contains two users named User1 and User2.
You need to ensure that the users can perform searches by using the Microsoft Purview portal. The solution must meet the following requirements:
• Ensure that User1 can search the Microsoft Purview Audit service logs and review the Microsoft Purview Audit service configuration.
• Ensure that User2 can search Microsoft Exchange Online mailboxes.
• Follow the principle of least privilege.
To which Microsoft Purview role group should you add each user? To answer, select the appropriate options in the answer area
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: User1: Audit Reader
User2: Data Investigator
Explanation: Audit Reader provides permission to search Microsoft Purview Audit logs and view audit configuration with least privilege. Data Investigator allows searching Exchange Online mailboxes for investigations without broader administrative permissions.
