When you plan to onboard a third-party SaaS application (App1) to Microsoft Defender for Cloud Apps (MDA/MCAS) and need to enforce session control policies such as monitoring or restricting downloads, the application must first be integrated with Microsoft Entra ID through Single Sign-On (SSO).
According to the Microsoft SC-300: Identity and Access Administrator study guide and official documentation, session controls in Defender for Cloud Apps depend on Conditional Access App Control, which only works with apps federated through Microsoft Entra ID (SSO-enabled). This integration allows Conditional Access to apply real-time monitoring and control of user sessions by routing the app's authentication through Entra ID.
Here's the required sequence outlined in the SC-300 materials:
* Configure SSO for App1 in Microsoft Entra admin center.
* Create a Conditional Access policy with "Use Conditional Access App Control."
* The policy then redirects sessions through Defender for Cloud Apps to enforce session controls (e.g., block download, monitor activity).
Other options do not achieve the initial requirement:
* A. Cloud Discovery only identifies unsanctioned apps but cannot apply session controls.
* B. Traffic forwarding profile applies to Global Secure Access, not SaaS onboarding.
* D. OAuth app policy targets API permissions, not real-time session enforcement.

When an application running on an Azure VM needs to authenticate using its system-assigned managed identity, it must request a token from the Azure Instance Metadata Service (IMDS). This service is accessible via a non-routable IP address - 169.254.169.254 .
The correct request URI pattern is:
http://169.254.169.254/metadata/identity/oauth2/token
This IP is used exclusively by Azure VMs to securely obtain tokens for managed identities without requiring credentials in the code.
Microsoft's documentation specifies:
"Applications running on Azure resources can request tokens from the Azure Instance Metadata Service (IMDS) endpoint at 169.254.169.254." Other options:
* 127.0.0.1 - loopback address (not used for IMDS)
* 108.143.161.25 - external public IP (irrelevant)
* 172.16.1.5 - private VM IP, not used for token requests

The exhibit shows Pass-through authentication (PTA) enabled with two agents and Password Hash Sync (PHS) enabled. SC-300 materials state that when both PTA and PHS are enabled, Azure AD can fall back to password hash verification if PTA agents are unavailable. With connectivity from on-premises to the Internet lost , PTA agents cannot validate passwords; however, PHS continues to allow cloud authentication for synchronized users. Therefore:
* User1 (cloud-only) authenticates in Azure AD directly, unaffected by on-prem connectivity.
* User2 (directory-synced) can still sign in because PHS is enabled and provides backup authentication when PTA is unreachable.
* User3 (guest) authenticates in the home tenant, which is independent of your on-prem connectivity; the host tenant simply relies on the external identity.
SC-300 explicitly teaches that enabling PHS alongside PTA provides resiliency for sign-in and is a recommended best practice. Consequently, all three users can sign in under the described outage.

Explanation:

Explanation:
< User1 can join four additional Windows 10 devices to Azure AD. # No
2# # Admin1 can set "Devices to be Azure AD joined or Azure AD registered require Multi-Factor Authentication" to Yes. # Yes
3# # Admin2 is a local administrator on Device3. # No
This scenario draws from Module: Manage device identities in Azure Active Directory in the Microsoft SC-
300 Official Study Guide and Microsoft Learn content.
Statement 1: User1 can join four additional Windows 10 devices to Azure AD - NO In the Device Settings, the "Maximum number of devices per user" is configured as 5. User1 already has one Azure AD joined device (Device1) and three Azure AD registered devices (Device2, Device3, Device4). Since both Azure AD joined and Azure AD registered devices count toward the same limit, User1 has already registered 4 devices.
This means they can add only one more, not four additional Windows 10 devices. Therefore, the statement is No.
Microsoft documentation states: "The maximum number of devices per user setting applies collectively to all Azure AD-joined and Azure AD-registered devices." Statement 2: Admin1 can set Devices to be Azure AD joined or Azure AD registered require MFA to Yes - YES The Cloud Device Administrator role (Admin1's role) has the delegated permissions to manage device settings in Azure AD, including enforcing MFA requirements for device registration and join operations. The role allows management of the Azure AD device configuration blade, including toggling settings like MFA for join/register, join limits, and device ownership policies. Therefore, Admin1 can enable the MFA requirement for device join/registration.
As per Microsoft Learn: "Cloud Device Administrator can manage all aspects of device settings, including device join and registration MFA requirements." Statement 3: Admin2 is a local administrator on Device3 - NO Admin2 holds the Device Administrator role.
However, per Microsoft's documentation, only Azure AD-joined Windows 10 devices grant local administrator rights to users in the Device Administrator role. Azure AD-registered devices (such as Device3) are personal devices that do not have local administrator assignment through Azure AD roles. Since Device3 is Azure AD registered, not joined, Admin2 is not a local admin on it.
Microsoft guidance clarifies: "Users assigned to the Device Administrator role are added as local administrators only on Azure AD-joined devices, not on Azure AD-registered or hybrid devices."
