Topic 1, Contoso Ltd
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.

In Microsoft Defender for Cloud (previously Azure Security Center and Azure Defender), email notifications for security alerts are configured under the "Pricing & settings" section of the workspace or subscription settings. According to Microsoft documentation, each subscription connected to Defender for Cloud has a "Pricing & settings" page that allows administrators to manage configurations such as Defender plan activation, data collection settings, and email notifications for security alerts .
To enable the SOC team to receive alert notifications, you navigate to Microsoft Defender for Cloud # Environment settings # [Select Subscription] # Pricing & settings # Email notifications . There, you can specify:
* The email addresses (up to 200) that will receive alerts.
* Whether to send notifications for high-severity alerts only or for all alerts.
* Whether to send to subscription owners, contributors, or specific emails .
This configuration ensures that alert emails are automatically sent whenever Defender for Cloud generates new security alerts, allowing the Security Operations team to stay informed without manual monitoring.
The other options are incorrect because:
* Security solutions is for integrating third-party or partner security products.
* Security policy defines compliance and assessment standards.
* Security alerts shows existing alerts but does not control notification settings.
* Azure Defender is the protection plan; it doesn't control notification preferences.
Therefore, the correct answer is C. Pricing & settings .

Notebooks are interactive tools that allow you to run Python code, query data, perform machine learning, and create visualizations. Notebooks can help you hunt for threats, investigate incidents, and perform data analysis using Microsoft Sentinel data and external data sources.

Enable Auto-Provisioning from Defender for Cloud. And there you will be ask which Secrity Events should be stored. It is Nonne - Common - All. And without enabling Defender for servers in the Defender for Cloud Portal this won't work.
