Question 1
You have three Azure subscriptions. Each subscription contains multiple virtual machines that run Windows Server.
You have a Microsoft Sentinel workspace.
You need to ensure that failed sign-in attempts from all the virtual machines can be analyzed by using Microsoft Sentinel. The solution must minimize administrative effort.
What should you do first?
A. From the Microsoft Defender portal, install the Windows Security Events solution.
B. On each virtual machine, create an event subscription.
C. On each virtual machine, install the Azure Connected Machine agent.
D. From the Microsoft Defender portal, install the Syslog solution.
Show Answer
Correct Answer: A
Explanation: Failed sign-in attempts on Windows Server are recorded in Windows Security Event logs (e.g., Event ID 4625). The Windows Security Events solution is the modern, recommended Microsoft Sentinel data connector that uses Azure Monitor Agent and Data Collection Rules. It can be enabled once and scoped across multiple subscriptions, automatically onboarding VMs and minimizing per-VM administration. Other options either apply to non-Windows data (Syslog), require per-VM effort, or are unnecessary for Azure VMs.
Question 1
HOTSPOT
-
You have a Microsoft 365 subscription that uses Microsoft Defender XDR.
You plan to investigate suspicious activity in the subscription by using Microsoft Graph activity logs.
You need to search for requests to delete resources from the subscription and identify the users that initiated the requests.
How should you complete the KQL query? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: matches
AccountName
Explanation: `matches` correctly applies the regex to filter DELETE requests targeting user resources. Projecting `AccountName` surfaces the identity of the user associated with the request after joining with IdentityInfo.
Question 2
HOTSPOT
-
You have the resources shown in the following table.
You have an Azure subscription that uses Microsoft Defender for Cloud.
You need to use Defender for Cloud to protect VM1 and Server1. The solution must meet the following requirements:
• Support Advanced Threat Protection and vulnerability assessment.
• Register each SQL Server 2022 instance as a SQL virtual machine.
• Minimize implementation and administrative effort.
What should you deploy to each server? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: VM1:
A VM extension only
Server1:
Azure Connected Machine agent and VM extension
Explanation: VM1 is an Azure VM, so Defender for Cloud and SQL registration are enabled by deploying the required VM/SQL extensions only. Server1 is on‑premises, so it must first be onboarded to Azure Arc using the Azure Connected Machine agent, and then the required VM/SQL extensions are deployed to enable Advanced Threat Protection and vulnerability assessment with minimal effort.
Question 2
You have a Microsoft 365 subscription.
You have the devices shown in the following table.
All the devices are onboarded to Microsoft Defender for Endpoint.
You are investigating a potential malware exploit on the devices.
You need to review the system log of each device. The solution must minimize disruptions to the devices.
What should you do for each device first in the Microsoft Defender portal?
A. Isolate the device.
B. Collect an investigation package.
C. Initiate an automated investigation.
D. Initiate a live response session.
Show Answer
Correct Answer: B
Explanation: To review system logs while minimizing disruption, the first action should be **Collect an investigation package**. This action non-intrusively gathers system logs, event data, and diagnostics into a downloadable package without interacting live with the device or affecting the user. Live response or isolation are more disruptive, and automated investigation performs broader remediation rather than simple log review.
Question 3
HOTSPOT
-
You have a Microsoft 365 subscription named contoso.com that contains a Windows 11 device named Device1. Device1 is onboarded to Microsoft Defender for Endpoint.
You perform the following actions:
• From Defender for Endpoint, create the device groups shown in the following table.
• Onboard an Android device named Device2 to Defender for Endpoint.
To which device groups will each device be added? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: Device1:
Group2 only
Device2:
Group1 only
Explanation: Microsoft Defender for Endpoint assigns a device to the first matching device group based on rank.
• Device1 (Windows 11, name starts with "Device", domain contoso.com): Matches Group2 and Group3, but Group2 has higher priority.
• Device2 (Android): Matches Group1 (OS is Android). Other rules do not apply.
Question 3
You have a Microsoft Sentinel workspace that contains the following tables.
You need to investigate the log data by using a search.
Which tables can you search?
A. Table3 only
B. Table1 and Table3 only
C. Table3 and Table4 only
D. Table1, Table3, and Table4 only
E. Table1, Table2, Table3, and Table4
Show Answer
Correct Answer: A
Explanation: Microsoft Sentinel Search can query only Analytics tables that have data in the Interactive retention period. Basic tables are not searchable with Search, and archived data must be restored before it can be queried. Of the listed tables, only Table3 is an Analytics table with Interactive retention, so it is the only searchable table.
Question 4
You have 1,000 on-premises Windows 11 Pro devices that are onboarded to Microsoft Defender for Endpoint.
You have a Microsoft 365 subscription that uses Microsoft Defender XDR.
You identify that an attacker performed the following actions on a device:
• Modified the file system path of a registry-based antivirus exclusion
• Downloaded a malicious file to the file system path
You initiate a live response session on the device.
You need to remove the malicious file.
Which command should you run?
A. collect
B. getfile
C. undo
D. remediate
Show Answer
Correct Answer: D
Explanation: In a Microsoft Defender for Endpoint Live Response session, **remediate** is the command used to remove malicious files or objects from the device. The other commands only collect or retrieve data or revert specific changes and do not delete the malicious file.
Question 4
HOTSPOT
-
You have a Microsoft Sentinel workspace named Workspace1.
The AzureActivity table in Workspace1 has the following retention periods:
• Interactive: 180 days
• Total: 180 days
You need to modify the retention periods to meet the following requirements:
• Minimize the costs associated with storing data in the table.
• Maximize the period during which the table data remains available.
How should you configure each retention period? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: Interactive: 30 days
Total: 2 years
Explanation: Set the shortest interactive retention to reduce high-cost hot storage, and the longest total retention to keep data available in low-cost archive for the maximum period.
Question 5
You have two Microsoft Entra tenants named Tenant1 and Tenant2. Each tenant is linked to an Azure subscription. Tenant1 contains a group named Group1. Tenant2 contains a group named Group2.
You need to implement Microsoft Sentinel for each tenant. The solution must meet the following requirements:
• Ensure that Group1 can manage security incidents for Tenant1 and Tenant2 in a single workspace.
• Ensure that Group2 can manage security incidents only for Tenant2.
• Minimize the use of guest accounts.
• Minimize administrative effort.
• Minimize costs.
What should you include in the solution?
A. one workspace and Privileged Identity Management (PIM)
B. one workspace and multiple role-based access control (RBAC) role assignments
C. two workspaces and Azure Lighthouse
D. two workspaces and granular delegated admin privileges (GDAP)
Show Answer
Correct Answer: C
Explanation: Using two Microsoft Sentinel workspaces—one per tenant—keeps data isolated and minimizes cost and administrative complexity. Azure Lighthouse enables Group1 (from Tenant1) to manage Sentinel incidents across both tenants without guest accounts, providing single-pane-of-glass cross-tenant management. Group2 can be granted access only to Tenant2’s workspace, ensuring it manages incidents solely for Tenant2.
Question 6
You have a Microsoft 365 E5 subscription that contains 500 Windows 11 devices.
You have a Microsoft Defender for Endpoint deployment that has the following settings:
• Discovery mode: Basic
• Live Response: Disabled
• Enable EDR in block mode: Off
• Tamper Protection: Off
You need to implement automatic attack disruption in Microsoft Defender XDR.
What should you do?
A. Change Discovery mode to Standard discovery.
B. Set Live Response to On.
C. Set Tamper Protection to On.
D. Set Enable EDR in block mode to On.
Show Answer
Correct Answer: D
Explanation: Automatic attack disruption in Microsoft Defender XDR relies on endpoint detection and response (EDR) capabilities to actively block and contain malicious activity on devices. Enabling **EDR in block mode** allows Defender for Endpoint to take blocking and remediation actions during and after an attack, even if Microsoft Defender Antivirus is not the primary AV. The other settings (Discovery mode, Live Response, Tamper Protection) are not prerequisites for automatic attack disruption.
