According to Microsoft’s official Defender for Identity deployment documentation, setting up Microsoft Defender for Identity (MDI) on an on-premises domain controller (DC) such as DC1 requires a specific sequence of steps. MDI monitors and protects Active Directory from advanced threats by using sensors installed directly on domain controllers.

The correct sequence is as follows:

1️⃣ Provide global administrator credentials to the Azure AD tenant.

Microsoft Defender for Identity is created and managed in the Microsoft 365 Defender portal or Microsoft Security portal, which requires global administrator permissions to provision the MDI instance and connect it to the Azure AD tenant.

2️⃣ Create an instance of Microsoft Defender for Identity.

You must create an MDI instance in the portal before deploying any sensors. This instance defines your Defender for Identity workspace and generates the configuration package that sensors will later use to connect to the cloud service.

3️⃣ Provide domain administrator credentials to the on-premises Active Directory domain.

Domain admin credentials are required for the sensor installation because the sensor must access the domain controller’s security logs, event logs, and directory services to monitor authentication traffic and suspicious activities.

4️⃣ Install the sensor on DC1.

Since DC1 is a domain controller connected directly to the internet, the standard sensor (not the standalone sensor) is installed directly on it. The standalone sensor is used only when you do not want to install the sensor directly on a DC. The sensor automatically connects to the created MDI instance and begins collecting telemetry for detection.

This sequence aligns with Microsoft Defender for Identity deployment guidance, ensuring secure onboarding of DC1 while maintaining the principle of least privilege and meeting the business requirement to protect all domain controllers.

✅ Final Order:

Provide global administrator credentials →

Create instance of Microsoft Defender for Identity →

Provide domain administrator credentials →

Install the sensor on DC1.

The Defender for Cloud requirement states:

“The members of Group1 must be able to enable Defender for Cloud plans and apply regulatory compliance initiatives.”

According to Microsoft Defender for Cloud’s RBAC documentation, the Security Assessment Contributor role provides permissions to:

Enable and configure Defender plans,

Manage security policies and initiatives,

View and edit recommendations and compliance results.

This role gives enough permissions to perform Defender configuration tasks but follows the principle of least privilege, unlike broader roles like Owner or Contributor, which grant excessive rights.

✅ Answer for Question 9: C. Security Assessment Contributor

In Microsoft Defender for Endpoint (Plan 2), you can use indicator file hashes (IoC file hashes) to block files from executing or being downloaded. When you create a file hash indicator, you specify the exact file hash (for example, SHA-256 or MD5) and choose actions such as “block” or “remediate.”

However, an important detail is that file hash indicators are applied to specific files—that is, for a given executable or file content. You cannot use a hash indicator to block all files of a certain extension generically. If a given file has a different hash, it will not be blocked unless you add its specific hash. Because the question says you found suspected malware files sys, pdf, docx, xlsx, and you need to block users from downloading those files, only those files for which you can compute and apply a specific hash indicator can be blocked. The question implies you can create indicator hashes for each of those file names (assuming each has a unique hash).

Thus you can block all four (File1.sys, File2.pdf, File3.docx, File4.xlsx) by adding each as an indicator hash. The choice E lists all four. That is consistent with Microsoft’s statements that “you can create indicators that define detection, prevention, or exclusion of entities,” and file hash indicators specifically apply to those files.

Options that exclude some file types (e.g. only blocking sys and docx but not pdf or xlsx) would leave gaps, which doesn’t satisfy the requirement of blocking all those suspected files. Hence E is the correct answer.
