Microsoft SC-300 - Microsoft Identity and Access Administrator

Assigning built-in directory roles (like Device Administrators) to a group requires a role-assignable group. The SC-300 documentation explains: “You can assign Azure AD roles to a cloud security group by creating the group with the setting ‘Azure AD roles can be assigned to the group.’” It further emphasizes: “This attribute is immutable; you must decide at creation time. You cannot convert an existing group to be role-assignable later.” When a standard security group is not created as role-assignable, it will not appear in the picker when attempting to assign a directory role—exactly the behavior observed: “groups that aren’t role-assignable cannot be selected for Azure AD role assignments.” Therefore, the first step is to recreate IT_Group1 as a role-assignable security group (often called an “eligible for role assignment” group) and then assign the Device Administrators role to that group. Changing membership types (Dynamic User or Dynamic Device) or adding owners does not convert an existing group into a role-assignable one and thus would not resolve the issue.

In Microsoft Entra ID (Azure AD), the per-user device cap is controlled in Devices > Device settings. The SC-300 materials describe that administrators can configure “Users may join devices to Azure AD” and the “Maximum number of devices per user” . The guide notes that this limit defaults to five and is used to “control how many devices a user can join or register in Azure AD”; when users reach the limit, “they cannot add additional devices until the limit is increased or an existing device is removed.” For scenarios like field or sales staff who use multiple devices, the study content recommends adjusting this value to meet business needs. Because A. Datum’s sales users hit the current cap and a requirement states “Increase the maximum number of devices that can be joined or registered to Azure AD to 10,” the fix is to change the tenant’s Device settings—not User settings, Access reviews, or Security defaults. This aligns with the exam objective to configure device settings for Azure AD join and registration and addresses the precise symptom reported by users.

Azure AD External collaboration settings govern who can bring guests into the tenant. The SC-300 content specifies: “External collaboration settings let you control who can invite guests (Anyone, Members, Guests, or Only admins and users in the Guest Inviter role) and whether guests can invite.” It also highlights: “To restrict guest invitations to administrators or designated inviters, configure External collaboration to ‘Only admins and users in the Guest Inviter role’ and disable guest-to-guest invitations if required.” Because the problem states that “Anyone in the organization can invite guest users, including other guests and non-administrators,” the remediation is to tighten External collaboration settings so only approved roles (e.g., Global admins, Guest Inviter, or specific administrators) can invite. Access reviews address periodic entitlement verification, Conditional Access enforces sign-in/session policies, and Continuous Access Evaluation relates to token lifetime/signal-based revocation; none of these change who can send guest invitations. Adjusting External collaboration settings directly resolves the issue and aligns with the requirement that “only users that are assigned specific admin roles can invite guest users.”

According to the Microsoft SC-300: Identity and Access Administrator official study guide and the Microsoft Learn “Implement and manage Azure AD Identity Protection” module, Azure AD Identity Protection detects two primary categories of risks: user risks and sign-in risks.

User Risk Policy: A user risk represents the probability that a user ' s identity (credentials) has been compromised. Examples of user risk signals include leaked credentials , unusual sign-ins from different geographies , or sign-ins from infected devices . The Exam Ref SC-300 specifically lists “leaked credentials detected on the dark web or other compromised repositories” as the main trigger for a user risk policy. Such a policy can automatically force password change or enforce MFA to remediate the threat.

Sign-in Risk Policy: A sign-in risk reflects the likelihood that a specific authentication attempt is not performed by the legitimate user. Sign-in risk is based on context, such as sign-ins from suspicious browsers , anonymous IP addresses (like TOR networks) , or impossible travel sce narios . The SC-300 documentation highlights these examples as conditions best handled with a sign-in risk policy, where conditional access can block or require MFA for the risky sign-in attempt.

Therefore:

Leaked credentials are addressed through a User Risk Policy, since the account itself is compromised.

Sign-ins from suspicious browsers and access from anonymous IP addresses are handled through Sign-in Risk Policies, as they relate to risky sessions rather than compromised identities.

In SC-300, Azure AD Identity Protection is the prescribed control to “automatically detect and remediate externally leaked credentials.” That specific user risk—Leaked credentials—relies on Microsoft comparing known breached username/password pairs with what Azure AD can evaluate. The study materials explain that Identity Protection “detects leaked credentials when Microsoft finds a match with the user’s current credentials,” and also note that password hash synchronization (PHS) can be enabled even if your sign-in method is Pass-through Authentication or federation. A common exam call-out is that without PHS, Azure AD has no hash to compare, so the leaked-credential signal is unavailable. Enabling PHS (you can keep PTA as the active sign-in method) allows Identity Protection to raise user risk and enforce policy actions such as require password change or block access. By contrast, Azure AD Password Protection addresses banned/weak passwords at change time, not breached-credential telemetry; federation choices (e.g., PingFederate) don’t deliver the leaked-credential signal; and authentication method policy controls how users perform MFA (e.g., methods) rather than whether leaked credentials are detected. Therefore, to meet the requirement to “automatically detect and remediate externally leaked credentials,” the minimum correct step is to enable password hash synchronization while retaining PTA—exactly as recommended in SC-300 guidance.

For Identity Governance (Entitlement Management), the materials clarify who can create and manage access reviews of access packages: “To create or manage access reviews for access packages, you must be a Global administrator, an Identity Governance administrator, a catalog owner for the catalog that contains the access package, or an access package manager.” The exam text also states: “User administrator does not grant the ability to manage entitlement management access reviews unless the user is delegated as a catalog owner or access package manager.” Given the scenario’s user roles, User3 (Identity Governance administrator) and User5 (Global administrator) satisfy these permissions and therefore can create and manage the access review for Package1. By contrast, User4 (User administrator) cannot perform this task by role alone. This selection follows the least-privilege guidance emphasized in SC-300: use specialized governance roles (Identity Governance admin or delegated catalog roles) rather than broad directory roles when possible.

According to the Microsoft SC-300: Identity and Access Administrator Study Guide and the Microsoft Learn module “Implement and manage synchronization for Azure AD” , Azure AD Connect Cloud Sync is the preferred solution when you need to synchronize objects from multiple Active Directory (AD DS) forests without establishing forest trusts .

The scenario specifies that trust relationships must NOT be established between adatum.com and litware.com , but A. Datum must still sync the AD DS users and groups of litware.com to their existing Azure AD tenant (adatum.com).

The SC-300 training materials clarify:

“Azure AD Connect cloud sync enables syncing from multiple AD forests to a single Azure AD tenant without the need for forest trusts or a full Azure AD Connect installation in each forest.”

Unlike staging mode (which provides a standby sync server for failover) or extending the same Azure AD Connect instance to another domain (which requires trust relationships and network connectivity between forests), Azure AD Connect Cloud Sync uses lightweight agents and does not depend on forest trust.

Therefore, to meet the requirement of syncing Litware’s AD DS to A. Datum’s Azure AD tenant without creating a trust , the correct choice is to configure Azure AD Connect Cloud Sync between the Azure AD tenant and the litware.com domain.

In Azure AD Identity Governance, application access granted through Entitlement management is organized around catalogs and access packages. The SC-300 study materials explain that “a catalog is a container for resources and access packages” and that you must add your enterprise applications (or the groups tied to those apps) to a catalog before you can build access packages that users can request. Creating the catalog first enables you to place only the required resources in scope and to delegate day-to-day ownership: “catalog owners can manage the resources and access packages within their catalog without being tenant-wide admins,” satisfying the delegation requirement to use custom catalogs and least privilege. After the catalog exists, you create one or more access packages that include the application (or groups) and policies that control who can request, how they are approved, and for how long. Identity Governance then lets you track access package assignments and review who has the app over time. By contrast, programs are used to group and report on governance initiatives (for example, collections of access reviews) rather than to onboard application resources; and modifying user/admin consent settings affects app consent behavior, not the lifecycle tracking of assignments. Therefore, the correct first step to track application access assignments while meeting the delegation requirements is to create a catalog.

Server1

On DC1

Azure AD Password Protection has two components: the DC agent (installed on domain controllers) and the proxy service (installed on one or more member servers). The SC-300 materials and Microsoft Identity Governance guidance explain that the proxy service is required when domain controllers do not have direct internet access. The proxy retrieves the password protection policy and custom banned password list from Azure AD over outbound HTTPS and makes it available to DC agents. The documentation further states that you should deploy at least one proxy per forest and two for high availability, and that domain controllers do not need internet connectivity when a proxy is deployed. In this scenario, DCs are explicitly blocked from internet access, so the proxy must be placed on member servers. Both SERVER1 (Application Proxy connector) and SERVER2 (Azure AD Connect) are domain-joined member servers with internet connectivity and are appropriate locations for the AzureADPasswordProtectionProxy service; selecting both provides the recommended redundancy. The custom banned password list is configured in Azure AD at the tenant level (as part of Azure AD Password Protection settings), not on individual servers. Once configured, the policy and list are downloaded by the proxy and enforced by the DC agent during password set or change operations, satisfying the requirement to implement a banned password list for the litware.com forest.
