SC-900 Describe the capabilities of Microsoft Entra — Timed 100 Questions

Question 1

A company wants to require multi-factor authentication (MFA) for all users accessing a financial application, but only when they sign in from outside the corporate network. Which Microsoft Entra ID feature should be used?

Accepted Answer

Conditional Access. Conditional Access is the correct choice because it allows administrators to define policies that enforce multi-factor authentication (MFA) based on specific conditions, such as network location. In this scenario, a Conditional Access policy can be configured to require MFA only when users access the financial application from outside the corporate network, using the 'Locations' condition to distinguish trusted IP ranges from external sign-ins. This granular control directly addresses the requirement without affecting internal access.

Answer

Identity Protection

Answer

Privileged Identity Management (PIM)

Answer

Self-Service Password Reset (SSPR)

Question 2

An organization uses Microsoft Entra ID Protection. A user's sign-in is flagged with a risk level of 'High' because of an anonymous IP address. The administrator wants to automatically block the sign-in while allowing the user to self-remediate. Which should be configured?

Accepted Answer

A sign-in risk policy configured to block access. A sign-in risk policy in Microsoft Entra ID Protection can be configured to automatically block access when a sign-in is detected as high risk (e.g., from an anonymous IP address). This policy operates at the sign-in level, allowing the administrator to block the sign-in while still enabling the user to self-remediate (e.g., by signing in again after the risk is mitigated). Option C directly matches this requirement.

Answer

A Conditional Access policy requiring MFA for high-risk sign-ins

Answer

A user risk policy configured to require a password change

Answer

An MFA registration policy for all users

Question 3

A company manages Azure resources for multiple departments. The security team needs to grant IT administrators temporary, just-in-time access to high-privilege roles (e.g., Contributor, Owner) only when needed, with approval workflows. Which Microsoft Entra ID capability should they configure?

Accepted Answer

Privileged Identity Management (PIM). Privileged Identity Management (PIM) is the correct Microsoft Entra ID capability because it provides just-in-time (JIT) activation of high-privilege roles like Contributor and Owner, with time-bound approvals and approval workflows. PIM allows administrators to request temporary elevation to a role, which must be approved by designated approvers, and the access automatically expires after the specified duration. This directly addresses the requirement for temporary, approval-based access to privileged roles.

Entitlement Management (Identity Governance)

Question 4

A company uses Microsoft Entra ID and needs to regularly review membership of a group that grants access to a sensitive HR application. The identity team wants to automate quarterly reviews and automatically remove users who fail to respond or are denied by the reviewer. Which Microsoft Entra ID feature should they use?

Accepted Answer

Access Reviews. Option D is correct because Microsoft Entra Access Reviews are specifically designed to automate periodic attestation of group memberships, including the ability to automatically remove users who do not respond or are denied by the reviewer. This feature supports quarterly recurring reviews and integrates directly with Entra ID groups to enforce access governance for sensitive applications.

Question 5

A company uses Microsoft Entra ID and wants to enforce multi-factor authentication (MFA) only for external guest users, while allowing internal employees to sign in without MFA. Which Conditional Access setting should be configured?

Accepted Answer

Target the 'Guest or external users' identity type. Option C is correct because Conditional Access allows targeting the 'Guest or external users' identity type, which enables MFA enforcement exclusively for external guest users without affecting internal employees. This setting leverages the user type attribute in Microsoft Entra ID to differentiate between internal and external identities, providing granular control over authentication requirements.

Answer

Require MFA for all users

Answer

Exclude internal users by group

Answer

Use Identity Protection's user risk policy

Question 6

A company wants to block all sign-ins using legacy authentication protocols because these protocols do not support multi-factor authentication (MFA). Which component of a Microsoft Entra ID Conditional Access policy should be configured to achieve this?

Accepted Answer

Conditions (Client apps). To block legacy authentication protocols, you configure the 'Client apps' condition in a Conditional Access policy. This setting allows you to target specific authentication clients, such as Exchange ActiveSync, POP3, IMAP, and SMTP, which do not support MFA. By selecting 'Exchange ActiveSync clients' and 'Other clients' under the Client apps condition, you can enforce a block on all sign-ins using these legacy protocols.

Question 7

An organization uses Microsoft Intune to manage devices. They want to ensure that only devices marked as compliant can access corporate email in Exchange Online. Which Conditional Access component should they configure?

Accepted Answer

Grant controls -> Require device to be marked as compliant. Option B is correct because the 'Require device to be marked as compliant' grant control in Conditional Access enforces that only Intune-compliant devices can access Exchange Online. This integrates with Microsoft Entra ID to check the device compliance status reported by Intune before granting access to corporate email.

Answer

Conditions -> Device state

Answer

Sign-in risk policy

Answer

Session controls -> Use Conditional Access App Control

Question 8

A company uses Microsoft Entra ID. The IT department wants to automatically assign a Microsoft 365 E5 license to all users in the Sales department based on their department attribute. Which Microsoft Entra ID feature should they use?

Accepted Answer

Dynamic Groups. Dynamic Groups in Microsoft Entra ID allow automatic user membership based on user attributes, such as the department attribute. By creating a dynamic group rule like `user.department -eq "Sales"`, the system automatically assigns the group membership and can then apply a Microsoft 365 E5 license via group-based licensing.

Question 9

A security team is using Microsoft Entra ID Protection. They want to automatically block sign-ins from known malicious IP addresses, but if a user's account is compromised (e.g., leaked credentials), they want to force the user to change their password upon next sign-in. Which two risk policies should they configure? (Select all that apply.)

Accepted Answer

Sign-in risk policy set to 'Block access' for High risk. Option A is correct because the sign-in risk policy in Microsoft Entra ID Protection can be configured to automatically block access when a sign-in is detected as high risk, such as from a known malicious IP address. This policy evaluates real-time risk signals during authentication and enforces the specified action (e.g., 'Block access') without requiring additional Conditional Access policies.

Answer

MFA registration policy

Answer

Conditional Access policy with a custom block rule

Question 10

A company uses Microsoft Entra ID and wants to allow external business partners to request access to a specific application through an approval process. The access should be time-limited and automatically expired. Which Microsoft Entra ID feature should be configured?

Accepted Answer

Entitlement management. Microsoft Entra entitlement management (part of Identity Governance) allows organizations to manage access for internal and external users through access packages, which include policies for requesting, approving, and automatically expiring access. Conditional Access is for enforcing policies during sign-in, PIM manages privileged roles, and self-service group management allows users to manage group membership but does not provide approval workflows or time-limited access for external users out-of-the-box.

Question 14

A company wants to allow external business partners to access its internal applications using their own corporate credentials (e.g., their Microsoft Entra ID or Google account), without creating separate user accounts in the company's directory. Which Microsoft Entra ID feature should they use?

Accepted Answer

B2B collaboration. B2B collaboration allows the company to grant external business partners access to its internal applications using their own corporate identities (such as Microsoft Entra ID or Google accounts) without creating separate user accounts in the company's directory. It leverages federation trust and cross-tenant authentication, enabling partners to authenticate with their home organizations while accessing resources in the host tenant.

Question 15

A company needs to grant IT administrators temporary and time-limited access to privileged roles in Microsoft Entra ID (Azure AD). The access must require approval from a manager and be automatically revoked after the task is completed. Which Microsoft Entra ID feature should be used?

Accepted Answer

Privileged Identity Management (PIM). Privileged Identity Management (PIM) in Microsoft Entra ID provides just-in-time (JIT) privileged access by allowing administrators to activate eligible role assignments for a limited duration. It supports approval workflows (e.g., manager approval) and automatically deactivates the role when the activation time expires or the task is completed, meeting the requirement for temporary, time-limited, approved, and auto-revoked access.

Question 16

A company requires that all users accessing a financial application from outside the corporate network must complete multi-factor authentication (MFA). The IT team is configuring a Microsoft Entra ID Conditional Access policy to enforce this requirement. Which component of the policy should be configured to apply the MFA requirement?

Accepted Answer

Grant controls. Grant controls are the component of a Conditional Access policy that enforce the actual access requirements, such as requiring multi-factor authentication (MFA). By configuring the 'Require multi-factor authentication' checkbox under Grant controls, the policy ensures that users must complete MFA before accessing the financial application. This is the correct setting to apply the MFA requirement.

Question 17

A company uses Microsoft Entra ID. The IT team wants to provide remote employees with secure, single sign-on (SSO) access to a critical on-premises web application that uses password-based authentication, without requiring a VPN connection. Which Microsoft Entra ID feature should they use?

Accepted Answer

Microsoft Entra Application Proxy. Microsoft Entra Application Proxy enables secure remote access to on-premises web applications by publishing them through an external endpoint, without requiring a VPN. It supports password-based SSO by securely storing and replaying credentials to the legacy application, allowing users to authenticate once via Entra ID. This makes it the correct choice for providing SSO to a password-based on-premises app without a VPN.

Question 18

A multinational corporation uses Microsoft Entra ID. The IT department wants to allow regional IT administrators in Europe to manage users and groups only for their own region, without granting them permissions to manage users in other regions. Which Microsoft Entra ID feature should they use?

Accepted Answer

B. Administrative Units. Administrative Units (AUs) in Microsoft Entra ID allow you to delegate administrative permissions scoped to a subset of users, groups, or devices. By creating an AU for the Europe region and assigning regional IT administrators to it, you restrict their management scope to only those objects within that AU, preventing them from managing users in other regions.

A. Conditional Access

Answer

C. Privileged Identity Management

Answer

D. Identity Governance

Question 19

A company uses Microsoft Entra ID. The security team wants to configure a policy so that when a user signs in from an unfamiliar location (not on the company's trusted IP ranges) or from an unfamiliar device, they are prompted for additional verification (e.g., MFA). However, if the sign-in is from a trusted location (e.g., office IP range) and a known device, no additional verification is required. Which Microsoft Entra ID feature should they configure?

Accepted Answer

Microsoft Entra Conditional Access. Microsoft Entra Conditional Access is the correct feature because it allows administrators to define policies that evaluate sign-in context—such as user location (via named locations with trusted IP ranges) and device state (compliant or hybrid Azure AD joined)—and then enforce actions like requiring MFA only when conditions are not met. This directly matches the requirement to prompt for additional verification from unfamiliar locations or devices while skipping it for trusted ones.

Question 20

A security administrator at an organization using Microsoft Entra ID needs to automatically detect user sign-ins that exhibit risky behavior, such as signing in from a suspicious IP address or using leaked credentials. The administrator also wants the system to automatically calculate a risk level for each user and take actions like requiring a password reset when risk is high. Which Microsoft Entra ID feature should the administrator use?

Accepted Answer

Identity Protection. Microsoft Entra ID Protection is the correct feature because it automatically detects risky sign-in behaviors—such as sign-ins from suspicious IP addresses, anonymous IP addresses, or leaked credentials—and calculates a user risk level. It can then automatically trigger remediation actions like requiring a password reset when the risk level is high, directly matching the administrator's requirements.
