According to the Microsoft Entra ID Protection section of the SC-300 Study Guide and the official Microsoft documentation on risk detections and retention, Microsoft Entra ID stores risky user activity and detections for 90 days. This includes logs of risky users, risky sign-ins, and risk detections identified by machine learning models and heuristic signals.
The retention period of 90 days ensures administrators can analyze user risk patterns, investigate compromised accounts, and implement mitigations such as Conditional Access or user risk policies. After 90 days, these logs are automatically purged unless exported to a SIEM such as Microsoft Sentinel for extended retention.
Microsoft Learn states:
"Identity Protection retains data for 90 days. Administrators can view risk detections, risky users, and risky sign-ins in the portal or query them using Microsoft Graph."

Explanation:
Identify all the accounts that are assigned the Global Administrator role permanently: Microsoft Entra Insights Review the PCI of User1: Analytics In Microsoft Entra Permissions Management, the Microsoft Entra Insights tab provides role-focused visibility into directory privileges. The SC-300 materials describe it as the place to surface "standing privileges for Microsoft Entra roles" and to identify accounts with high-risk assignments such as Global Administrator. The insights view surfaces who has those roles and whether they're permanent (standing) versus eligible or time-bound, enabling you to quickly "identify high-impact directory roles and users with persistent assignments." The Analytics tab is centered on identities, resources, and actions, featuring risk and usage metrics, including the Permission Creep Index (PCI). The study content explains that Analytics lets you "drill into an identity' s effective permissions and risk score (PCI) to compare granted vs. used permissions." For a specific user (e.
g., User1), you navigate to Analytics # Identities, search/select the user, and view the PCI card and detailed breakdown of unused vs. used permissions.
Accordingly: to find permanent Global Administrator assignments, use Microsoft Entra Insights; to review User1's PCI, use Analytics.

Explanation:

In SC-300, publishing an on-premises web app to Azure AD users is performed with Azure AD Application Proxy. The exam materials and Microsoft curriculum explain that you deploy an Application Proxy connector on a Windows Server joined to your on-premises network, which brokers requests to internal apps such as an ASP.NET site. The connector is designed for perimeter-friendly deployments: "Application Proxy connectors only make outbound connections to the Application Proxy service" and "no inbound ports need to be opened in the firewall." Because the connector initiates the session to Azure over TLS, the firewall requirement is simply to permit the connector's outbound HTTPS to the service endpoints. This aligns with the least- exposure pattern emphasized in Identity Governance: you avoid publishing inbound listener rules and still support Azure AD features like Conditional Access and MFA at the cloud edge. Alternatives in the list do not meet the publishing requirement: the Password Protection DC agent and Password Protection proxy service are for banned-password enforcement, and Web Application Proxy in Windows Server is a different reverse- proxy technology not required when using Azure AD Application Proxy. Therefore, to publish App1 securely to Azure AD users, install Azure AD Application Proxy on Server4 and allow outbound HTTPS from Server4 through Firewall1.

In Azure AD Privileged Identity Management (PIM) for Azure AD roles, the exam materials describe that you tailor how a role (for example, User administrator) is used by editing its Role settings. These settings control activation behavior, including require multi-factor authentication, justification, approval, assignment
/activation durations, and notifications . The guide states that administrators can "configure activation requirements and time-bound eligibility on a per-role basis" and "enforce approval workflows and MFA at activation." Access reviews are used to periodically verify who still needs a role , but they do not implement the operational changes to how the role is activated. Active assignments simply shows and changes who currently holds active/eligible assignments; it does not set policy for the role's activation behavior.
Administrative units scope certain directory tasks, but they are not how you change PIM activation/approval
/MFA requirements. Therefore, to meet planned changes for the User administrator role (such as least privilege activation with approval, justification, and MFA), you update PIM # Azure AD roles # User administrator # Role settings. This aligns with the SC-300 objective to "configure PIM settings and policies for Azure AD roles," ensuring governance by policy rather than ad-hoc assignment.

To Answer this question accurately, we must analyze the Combined Security Information Registration experience in Interrupt Mode for a new user within an Azure AD (Microsoft Entra ID) tenant where both MFA and SSPR are enabled.
1. Understanding Combined Registration in Interrupt Mode: According to Microsoft documentation on Combined security information registration , this feature allows users to register their security methods for both Azure AD Multi-Factor Authentication (MFA) and Self-Service Password Reset (SSPR) in a single, unified step.
* Interrupt Mode triggers when a user signs in and a policy (like Identity Protection or Conditional Access) requires them to register security infor mation immediately.
* Because the question states SSPR is enabled and MFA is enforced , the user is required to register methods that satisfy both policies.
2. Validating the Methods (Options Analysis):
* Option E: The Microsoft Authenticator app (Correct): The Microsoft Authenticator app is the primary and most recommended method in the combined registration flow. It satisfies the strong authentication requirement for MFA and can also be used for SSPR . Microsoft documentation explicitly lists the Microsoft Auth enticator app as a supported method that users can register during the combined experience.
* Option C: A one-time passcode email (Correct): While Email is not a valid method for Azure AD MFA (primary authentication), it is a supported and common method for SSPR .
* Documentation Extract: " Users can register the following methods... Email (SSPR only). "
* Since the question specifies that SSPR is enabled , the combined registration wizard requires the user to register SSPR methods in addition to MFA methods. Therefo re, registering an email address to receive a one-time passcode is a valid step User1 can take to complete the portion of the combined registration process related to SSPR.
* Option A: A FIDO2 security key (Incorrect for Initial Registration):
* Documentation Extract: " User registration of FIDO2 security keys... relies on the combined registration experience. Users must have already registered at least one Azure AD Multi- Factor Authentication method. "
* Because User1 is a new user (and likely does not have a Temporary Access Pass specified), they cannot use a FIDO2 key to complete the initial registration interrupt. They must first register a standard MFA method (like the Authenticator app) before they can add a FIDO2 key via the " Manage " mode (Security Info p age).
* Option B: A hardware token (Incorrect): Hardware OATH tokens are not self-registered by the user in the combined registration portal. They must be uploaded and assigned by an administrator via a CSV file. Therefore, User1 cannot " use " this method to complete the self-service registration process.
* Option D: Windows Hello for Business (Incorrect): Windows Hello for Business (WHfB) is provisioned at the device level (via Windows Settings or OOBE), not through the web-based Combined Registration interrupt wizard. Additionally, WHfB typically requires the user to have already completed MFA registration to provision the credential.
Conclusion: The only two methods from the list that a new user can actively register and use to complete the web-based Combined Registration interrupt wizard (satisfying both MFA and SSPR requirements) are the Microsoft Authenticator app (for MFA/SSPR) and Email (for SSPR).
