Existing Environment
End-User Environment
All users at Contoso use Windows 10 devices. Each user is licensed for Microsoft 365. In addition, iOS devices are distributed to the members of the sales team at Contoso.
Cloud and Hybrid Infrastructure
All Contoso applications are deployed to Azure.
You enable Microsoft Cloud App Security.
Contoso and Fabrikam have different Azure Active Directory (Azure AD) tenants. Fabrikam recently purchased an Azure subscription and enabled Azure Defender for all supported resource types.
Current Problems
The security team at Contoso receives a large number of cybersecurity alerts. The security team spends too much time identifying which cybersecurity alerts are legitimate threats, and which are not.
The Contoso sales team uses only iOS devices. The sales team members exchange files with customers by using a variety of third-party tools. In the past, the sales team experienced various attacks on their devices.
The marketing team at Contoso has several Microsoft SharePoint Online sites for collaborating with external vendors. The marketing team has had several incidents in which vendors uploaded files that contain malware.
The executive team at Contoso suspects a security breach. The executive team requests that you identify which files had more than five activities during the past 48 hours, including data access, download, or deletion for Microsoft Cloud App Security-protected applications.
Requirements
Planned Changes
Contoso plans to integrate the security operations of both companies and manage all security operations centrally.
Technical Requirements
Contoso identifies the following technical requirements:
* Receive alerts if an Azure virtual machine is under brute force attack.
* Use Azure Sentinel to reduce organizational risk by rapidly remediating active attacks on the environment.
* Implement Azure Sentinel queries that correlate data across the Azure AD tenants of Contoso and Fabrikam.
* Develop a procedure to remediate Azure Defender for Key Vault alerts for Fabrikam in case of external attackers and a potential compromise of its own Azure AD applications.
* Identify all cases of users who failed to sign in to an Azure resource for the first time from a given country. A junior security administrator provides you with the following incomplete query.

NOTE: Each correct selection is worth one point.

You have a Microsoft 365 subscription that uses Microsoft Copilot for Security.
You create a promptbook named Book1.
For Book1, you need to create a prompt that contains an input named IncidentID.
How should you format IncidentID?

You are using the Microsoft 365 Defender portal to conduct an investigation into a multi-stage incident related to a suspected malicious document. After reviewing all the details, you have determined that the alert tied to this potentially malicious document is also related to another incident in your environment. However, the alert is not currently listed as a part of that second incident. Your investigation into the alert is ongoing, as is your investigation into the two related incidents.
You need to appropriately categorize the alert and ensure that it is associated with the second incident.
What two actions should you take in the Manage alert pane to fulfill this part of the investigation?
Each correct answer presents a part of the solution.

Hotspot Question
You have a Microsoft Sentinel workspace named Workspace1.
The AzureActivity table in Workspace1 has the following retention periods:
- Interactive: 180 days
