Pass the Microsoft Certified: Identity and Access Administrator Associate SC-300 Questions and answers with Dumpstech

According to Microsoft Entra Conditional Access documentation and the SC-300 study guide, the What If tool in Azure AD is specifically designed to simulate Conditional Access policy results for a given user scenario. It allows administrators to input details such as user identity, location (IP address), device state, and application to determine which Conditional Access policies would apply before actual enforcement.

From Microsoft documentation:

“The What If tool allows admins to simulate a sign-in event for a specific user and evaluate which Conditional Access policies will be applied or excluded.”

Other options do not serve this function:

Access Reviews: Used for periodic access validation, not policy simulation.

Identity Secure Score: Provides improvement recommendations, not policy evaluation.

Microsoft 365 network connectivity test tool: Tests network connectivity, not policy application.

According to the Microsoft SC-300 Study Guide and Microsoft Learn module: “Implement and manage smart lockout and password protection”, Smart Lockout is a feature of Microsoft Entra Password Protection that helps prevent brute-force attacks by locking out accounts after repeated failed sign-in attempts.

The configuration for Smart Lockout includes two primary settings:

Lockout threshold — the number of failed sign-ins before locking the account.

Lockout duration — how long the account remains locked before another attempt is allowed.

These settings are managed under Password protection in the Entra admin center, not under user or sign-in risk policies (those are part of Identity Protection) or authentication strengths.

By configuring the lockout threshold to 10 failed sign-ins, you meet the requirement.

To compare and analyze role permissions of multiple users within an Azure AD tenant, the correct and most efficient tool is the Microsoft Entra admin center.

According to the Microsoft Identity and Access Administrator Study Guide and Microsoft Entra documentation, the Entra admin center provides the Roles and Administrators blade where administrators can:

View all directory roles.

Compare role permissions and assignments.

See which users have which roles and what each role allows.

The guide clarifies:

“Administrators can use the Entra admin center to view and compare role definitions and assigned members without using additional portals or manual PowerShell scripts.”

The other options serve different purposes:

Microsoft 365 Defender portal focuses on security incidents and threat management.

Microsoft 365 admin center handles licensing and user management but not detailed role comparison.

Microsoft Purview compliance portal deals with compliance, data governance, and auditing.

SC-300 coverage of Azure AD B2B collaboration states that to grant an external person access to your enterprise application, you invite them as a guest using their existing identity (such as a Microsoft account like user1@outlook.com). The documentation emphasizes that B2B “lets you collaborate with external users by adding them to your directory as guest users using their existing credentials.” Once invited, the guest can authenticate in their home identity provider and be assigned to the target enterprise application (App1) through app role assignment or group membership. You do not need to create a new managed user or add a WS-Federation identity provider for Outlook.com; Azure AD natively supports Microsoft Accounts for B2B invitations, controlled by External collaboration settings (which generally allow invitations to any domain by default). Consequently, to ensure the contractor can authenticate as user1@outlook.com and access App1, you should create a guest user (invite) in the contoso.com tenant and assign that guest to App1.

According to the Microsoft Identity and Access Administrator (SC-300) Study Guide and the Microsoft Learn module “Configure Azure AD Privileged Identity Management (PIM)”, Azure AD PIM provides two types of role assignments: Active and Eligible.

An Active assignment means the user permanently holds the role with immediate access. An Eligible assignment means the user can activate the role only when needed, after providing justification or approval. This follows the least privilege principle by reducing exposure to high-privilege roles.

The official documentation states:

“Users assigned as eligible must activate their role when they need to perform privileged tasks. This ensures that administrative privileges are granted only for a limited time and when necessary.”

Because all IT users currently have permanent Security Administrator roles, the correct remediation is to change their assignment type from Active to Eligible so they can activate it only when required. Options A and B relate to expiration settings but do not convert the assignment type.

In Azure AD B2B bulk invitations, the portal and CSV workflow require two core fields: the external user’s email address and the Invite Redirect URL that determines where the guest is sent to redeem the invitation. The study guide notes that the bulk invite template “must include the guest’s email address” and that “InviteRedirectUrl is required to define the post-invite redemption target (such as MyApps or a specific app).” Usernames and passwords are not supplied for B2B guests because “guest accounts authenticate with their home identity provider,” and there is no shared key involved in the invitation. Therefore, the only mandatory parameters to successfully process a bulk B2B invite are the email address of each guest and the redirection URL used during invitation redemption.

 User1 can use self-service password reset (SSPR) to reset his password: Yes

 If User1 accesses Microsoft Exchange Online, he will be authenticated by an on-premises domain controller: Yes

 User2 can be added to a Microsoft SharePoint Online site as a member: No

Based on Microsoft’s SC-300 Study Guide, Exam Ref SC-300: Microsoft Identity and Access Administrator, and Azure AD documentation, Azure AD Connect synchronization is governed by OU filtering, authentication method, and synchronization scope.

In this configuration, Azure AD Connect is set to “Sync selected domains and OUs,” and only OU1 is selected. Therefore, only objects (users, groups, etc.) located in OU1 are synchronized to Azure AD.

User1 (in OU1) is synchronized to Azure AD. Since password writeback is enabled (as seen in the configuration “Enable password writeback”), User1 can perform Self-Service Password Reset (SSPR) from Azure AD, and the change will write back to on-premises AD.Hence, the first statement is Yes.

Pass-through authentication is also enabled in the configuration (“Enable Pass-through authentication”). With PTA, when User1 accesses Microsoft 365 services (like Exchange Online), the authentication request is forwarded from Azure AD to an on-premises domain controller via the PTA agent. Therefore, authentication is handled by the local AD DS.Hence, the second statement is Yes.

User2 (in OU2) is not synchronized, as OU2 was not selected in the Domain/OU filtering configuration. This means User2 does not exist in Azure AD and cannot be granted access to Microsoft 365 resources, including SharePoint Online.Hence, the third statement is No.

This logic aligns with Microsoft documentation under “Configure filtering for Azure AD Connect,” which states:

“Only objects from selected domains and organizational units are synchronized. Users outside selected OUs are excluded from Azure AD and cannot authenticate or access cloud resources.”

According to the Microsoft SC-300: Identity and Access Administrator study materials and Microsoft Defender for Cloud Apps documentation, connecting third-party cloud applications such as GitHub, AWS, and Google Workspace to Defender for Cloud Apps allows the administrator to monitor user activities and OAuth app authentications in those external services.

The App connectors feature within Microsoft 365 Defender / Microsoft Defender for Cloud Apps provides deep visibility into sanctioned cloud applications by integrating their APIs. When an app connector is added — such as the GitHub app connector — Defender for Cloud Apps begins ingesting audit logs, including OAuth authorization events, sign-in attempts, and token consent grants.

The relevant Microsoft documentation states:

“App connectors use APIs from connected apps to extend visibility and control to cloud services, enabling monitoring of OAuth application authorizations and security activities.”

Since the question specifically asks to monitor OAuth authentication requests, adding the GitHub app connector fulfills this requirement because it brings OAuth consent and token data from GitHub into Microsoft 365 Defender (via Defender for Cloud Apps).

In Azure AD, password resets and session invalidation for non-administrative users are delegated with the least privilege by assigning the Helpdesk administrator (formerly Password administrator) role. The SC-300 materials explain that this role can reset passwords for standard users, force password change at next sign-in, require re-register for MFA, and revoke refresh tokens (invalidate sessions). The Authentication administrator has broader reach, including managing some authentication methods and affecting certain admin roles, which exceeds the minimum needed. Privileged Authentication Administrator can reset passwords for most admin roles (beyond the scope here) and is therefore not least-privileged. Security administrator focuses on configuring and viewing security features, not resetting user passwords. To enable SecAdmin1 to “manage passwords and invalidate sessions on behalf of non-administrative users” while honoring least privilege, assign Helpdesk administrator.
