Question 81
You need to configure a solution to enforce device compliance and prevent access from non-compliant devices to critical Azure applications. Which approach should you use?
A) Conditional Access with Intune device compliance policies
B) Assign permanent Global Administrator roles
C) Enable Security Defaults only
D) Require MFA without device checks
Answer: A
Explanation:
A Conditional Access combined with Intune device compliance policies ensures that only devices meeting specific security and configuration requirements can access critical Azure applications. This integration allows administrators to define policies that evaluate device posture, including OS version, encryption status, threat protection, and required security settings. SC-300 candidates must understand how to configure Conditional Access policies, assign device compliance requirements, and test policies to ensure proper enforcement. By leveraging this approach, organizations can maintain a secure environment where sensitive data and critical applications are protected from potential threats posed by unprotected or unmanaged devices. Intune provides detailed reporting on device compliance, allowing administrators to quickly identify non-compliant devices and remediate issues, which is crucial for auditing and regulatory compliance. Additionally, Conditional Access policies can be configured to provide access exceptions for specific scenarios, such as trusted locations or devices, without compromising overall security. The combination of Conditional Access and Intune aligns with zero-trust principles by continuously validating device and user integrity before granting access.
B Assigning permanent Global Administrator roles provides unrestricted access without considering device compliance. This approach is inherently risky and violates the principle of least privilege, exposing the organization to potential threats.
C Security Defaults enforce baseline protections such as MFA and blocking legacy authentication, but they cannot evaluate device compliance or prevent access from non-compliant devices. They are insufficient for scenarios requiring device posture enforcement.
D Requiring MFA strengthens authentication security but does not control device access. Without evaluating device compliance, non-compliant devices could still access critical applications, leaving the environment vulnerable.
Question 82
You need to detect suspicious sign-in activities, such as impossible travel or anonymous IP sign-ins. Which Azure AD feature should you configure?
A) Azure AD Identity Protection
B) Device compliance policies only
C) Security Defaults without monitoring
D) Assign Global Administrator roles for oversight
Answer: A
Explanation:
A Azure AD Identity Protection provides continuous monitoring of user sign-ins and evaluates potential risks using machine learning, threat intelligence, and behavioral analytics. It can detect unusual activities, such as impossible travel between locations, sign-ins from anonymous IP addresses, or atypical login patterns. SC-300 candidates should understand how to configure risk-based policies, define response actions for high-risk sign-ins, and monitor activity through reporting and auditing tools. Integration with Conditional Access allows automated responses, such as blocking access, enforcing MFA, or requiring a password reset for high-risk users. Identity Protection also generates detailed logs and risk reports, enabling organizations to investigate suspicious events and maintain compliance with security standards. By proactively monitoring and responding to suspicious sign-ins, organizations can reduce the likelihood of account compromise while maintaining operational efficiency. This feature aligns with zero-trust principles, which emphasize continuous verification of user identity and risk evaluation before granting access.
B Device compliance policies ensure that endpoints meet organizational security standards but cannot detect or evaluate risky sign-in activities. They are insufficient for monitoring anomalous authentication behaviors.
C Security Defaults provide baseline protections like MFA enforcement but do not perform risk-based sign-in analysis. Without Identity Protection, suspicious activities may go undetected.
D Assigning Global Administrator roles for oversight does not automatically detect risky sign-ins. Manual monitoring is reactive and inefficient, leaving the environment exposed to threats until intervention occurs.
Question 83
You need to grant temporary access to external partners for specific SharePoint sites and revoke it automatically after a set period. Which solution should you implement?
A) Azure AD B2B collaboration with access expiration
B) Assign permanent guest accounts
C) Share files via email only
D) Grant administrative privileges to external users
Answer: A
Explanation:
A Azure AD B2B collaboration allows organizations to invite external users to resources such as SharePoint sites, Teams channels, or applications. Access expiration policies ensure that external collaborators only have access for a predefined period, automatically revoking permissions after the expiration date. SC-300 candidates should know how to configure B2B invitations, define expiration settings, integrate MFA, and apply conditional access policies to external users. This approach minimizes administrative overhead, ensures compliance, and aligns with the zero-trust model by limiting the access window for external users. B2B collaboration also provides auditing, reporting, and access review capabilities, which help organizations monitor and control external access. Automated expiration prevents lingering accounts, reducing security risks and ensuring that temporary collaborators do not maintain unnecessary access. This method supports operational efficiency while maintaining secure collaboration environments for external partners.
B Assigning permanent guest accounts to external users significantly increases security risks. These accounts may remain active long after the collaboration or project has ended, creating what is often referred to as “lingering access.” Lingering accounts can be exploited by malicious actors, either internally or externally, to gain unauthorized access to sensitive data. This practice directly violates the principle of least privilege, which emphasizes that users should only have the minimum access necessary to complete their work for the shortest required duration. Over time, organizations with permanent guest accounts accumulate a large number of stale accounts, making it difficult to track, audit, and manage access. From a compliance perspective, these stale accounts may also violate regulations that require organizations to maintain strict control over who has access to sensitive resources. SC-300 candidates should understand that using temporary guest accounts with expiration policies is a best practice. Azure AD B2B collaboration allows administrators to set expiration dates for guest accounts, automatically revoking access when no longer needed. This approach reduces administrative overhead, minimizes security risks, and ensures that external users only have access for the intended duration, aligning with zero-trust security principles.
C Sharing files through email is a common but insecure method for collaborating with external users. When files are shared via email, they bypass critical governance controls such as auditing, monitoring, and policy enforcement. This means organizations cannot track who has accessed the files, when they were accessed, or if they were forwarded to unauthorized recipients. Email sharing provides no automated way to enforce access expiration or revoke permissions when a project ends. For temporary collaboration, this creates a significant security gap. Unlike built-in sharing mechanisms in Teams, SharePoint, or OneDrive, email sharing cannot enforce compliance policies, apply multi-factor authentication, or integrate with conditional access rules. SC-300 best practices recommend using secure sharing links with expiration dates, access reviews, and auditing enabled, ensuring that external users have controlled, time-limited access while maintaining visibility and compliance.
D Granting administrative privileges to external users is an extreme security risk. External collaborators should never have elevated privileges, as it exposes critical resources to potential misuse or compromise.
Question 84
You need to enforce multi-factor authentication selectively for high-risk sign-ins while allowing low-risk users to access resources without friction. Which approach should you implement?
A) Conditional Access policies integrated with Azure AD Identity Protection
B) Require MFA for all users
C) Enable Security Defaults without risk evaluation
D) Assign administrative roles for manual MFA enforcement
Answer: A
Explanation:
A Conditional Access policies integrated with Azure AD Identity Protection provide adaptive enforcement of multi-factor authentication. High-risk sign-ins, such as those from unusual locations or devices, trigger MFA requirements, while low-risk sign-ins proceed normally. SC-300 candidates must understand how to configure risk-based Conditional Access policies, define risk levels, and automate response actions. The solution detects anomalies such as impossible travel, unfamiliar devices, or atypical login behavior, triggering appropriate protective actions. By enforcing MFA based on risk, organizations can maintain security without imposing unnecessary barriers on low-risk users, optimizing user experience and productivity. Automated monitoring, logging, and auditing ensure compliance with organizational policies and regulatory frameworks. This approach aligns with zero-trust principles by continuously verifying user identity and adjusting access dynamically based on real-time risk evaluation, reducing the likelihood of account compromise while maintaining operational efficiency.
B Enforcing multi-factor authentication (MFA) for all users improves overall security by adding a second layer of protection beyond passwords. However, applying MFA uniformly can disrupt productivity, especially for users who consistently sign in from low-risk devices or trusted locations. A blanket MFA requirement does not differentiate between normal and risky sign-ins, which can lead to unnecessary prompts and frustration for users. Modern security frameworks, including zero-trust principles emphasized in SC-300, recommend adaptive, risk-based MFA enforcement. This approach evaluates factors such as device compliance, user behavior, location, and sign-in anomalies before requiring MFA. By tailoring MFA prompts to risk levels, organizations can maintain strong security while minimizing disruption for low-risk users. SC-300 candidates should understand that while universal MFA is better than none, it lacks the flexibility and intelligence provided by Conditional Access and risk-based policies.
C Security Defaults in Azure AD provide a simple, pre-configured baseline for protecting all users by enforcing MFA and blocking legacy authentication. While useful for small or less complex organizations, Security Defaults lack the ability to evaluate sign-in risk or provide selective enforcement. Users must complete MFA regardless of context, whether they are signing in from a trusted corporate device or an unusual location. Without risk-based assessment, Security Defaults cannot respond dynamically to high-risk sign-ins, location anomalies, or suspicious behavior. This rigid approach may improve baseline security but can create unnecessary friction for users and does not leverage modern identity protection features such as adaptive Conditional Access. SC-300 candidates need to recognize that Security Defaults are a starting point, not a replacement for more sophisticated, risk-aware policies.
D Manually assigning administrative roles to users as a method to enforce MFA is inefficient, reactive, and introduces operational risks. This approach relies on human intervention, which can result in delays, inconsistent enforcement, and temporary security gaps until corrective action is taken. Moreover, granting administrative privileges solely to enforce MFA violates the principle of least privilege, as users gain elevated rights unnecessarily. SC-300 best practices emphasize automated, policy-driven enforcement through Conditional Access and Azure AD Identity Protection. Automated, risk-based MFA ensures timely protection against threats without relying on manual intervention and minimizes the risk of human error.
Question 85
You need to automatically assign users to groups and roles based on department, job title, and geographic location. Which Azure AD feature should you use?
A) Dynamic groups with attribute-based membership rules
B) Manually assign groups after account creation
C) Enable Security Defaults only
D) Require MFA without role assignment
Answer: A
Explanation:
A Dynamic groups in Azure AD allow for automatic membership assignment based on user attributes such as department, job title, and location. This ensures that users immediately receive appropriate permissions and access rights upon account creation. SC-300 candidates should understand how to configure dynamic group rules, evaluate attribute expressions, and assign roles automatically through group membership. This approach minimizes administrative workload, reduces errors, enforces least privilege, and supports scalable identity and access management. Dynamic group assignments integrate with access reviews, compliance monitoring, and auditing, ensuring that permissions are consistently aligned with organizational policies. Automated assignment prevents privilege creep, improves operational efficiency, and supports regulatory compliance requirements. By leveraging dynamic groups, organizations maintain secure, consistent access policies while reducing human error and administrative overhead, aligning with zero-trust principles and modern enterprise governance strategies.
B Manual group assignment is time-consuming, error-prone, and inefficient at scale. It increases the risk of inconsistent permissions and violates least privilege principles.
C Security Defaults enforce baseline protections but do not provide dynamic membership or automated role assignment, making them insufficient for scalable identity management.
D Requiring MFA enhances security but does not assign roles or groups automatically, leaving users without proper access and increasing administrative overhead.
Question 86
You need to automatically assign users to security groups based on their department and revoke access when they leave the company. Which Azure AD feature should you use?
A) Assign permanent administrative roles
B) Dynamic groups with attribute-based membership
C) Security Defaults
D) Require MFA for all users
Answer: B
Explanation:
A Assigning permanent administrative roles manually is not scalable and does not account for changes in employee status. This can lead to privilege creep, where users retain unnecessary access even after leaving a department or organization. It also increases administrative workload and risks non-compliance with organizational policies.
B Dynamic groups with attribute-based membership in Azure AD provide automation for assigning users to security groups based on attributes like department, job title, or location. When a user joins a department, the dynamic membership rules automatically add them to the relevant group. Conversely, when they leave the company or change departments, the system removes them automatically. SC-300 candidates should understand how to construct membership rules using logical operators and user attributes, ensuring accurate and real-time access provisioning. This approach supports least privilege access, reduces administrative errors, and enforces zero-trust principles. Dynamic groups integrate seamlessly with role-based access control (RBAC) and Access Reviews, which help validate that only authorized users maintain access to sensitive resources. Furthermore, organizations can apply Conditional Access policies to these groups, enforcing MFA, device compliance, or location restrictions. Using dynamic groups enhances operational efficiency, supports compliance with regulations like GDPR or HIPAA, and ensures that access to applications and cloud resources aligns with user roles and responsibilities. Automated auditing and reporting capabilities provide visibility into group membership changes, enabling better security governance and accountability. In large enterprises with frequent personnel changes, dynamic groups ensure security policies are consistently enforced while minimizing manual intervention and reducing errors.
C Security Defaults enforce baseline security protections such as MFA and blocking legacy authentication. However, they do not provide automated group membership or dynamic access revocation based on user attributes or departmental changes.
D Requiring MFA for all users enhances security for authentication but does not address dynamic access management, group membership, or automatic revocation of privileges for employees leaving the organization.
Question 87
You need to enforce MFA for employees accessing HR systems only when they sign in from untrusted locations. Which method should you implement?
A) Require MFA for all users
B) Conditional Access policies with location-based rules
C) Assign Global Administrator roles to enforce MFA
D) Enable Security Defaults only
Answer: B
Explanation:
A Requiring MFA for all users increases security but creates unnecessary friction, especially for trusted locations or devices. It does not differentiate access scenarios or risk levels, which can frustrate employees and reduce productivity.
B Conditional Access policies in Azure AD allow organizations to enforce MFA adaptively based on context, such as user location, device compliance, or risk level. For HR systems, sensitive employee information must be protected, but requiring MFA for every login may be inefficient. SC-300 candidates should understand how to configure location-based rules, trusted IP ranges, and exceptions for corporate devices. By combining Conditional Access with Azure AD Identity Protection, sign-ins from untrusted or high-risk locations trigger MFA automatically, whereas trusted locations bypass the challenge, enhancing usability. This approach implements a zero-trust model, verifying identity continuously before granting access. Reporting and monitoring features provide visibility into user sign-ins, MFA enforcement, and risk patterns, supporting compliance and security audits. Location-based Conditional Access ensures both strong protection for sensitive resources and a smooth user experience, aligning security policies with organizational needs.
C Assigning Global Administrator roles to enforce MFA is not practical. Admin roles do not inherently enable conditional enforcement and require manual application, which does not scale efficiently for multiple users.
D Security Defaults enforce baseline protections for all users but lack flexibility for location-specific conditional MFA enforcement, making them unsuitable for this scenario.
Question 88
You need to provide temporary access to external consultants for Teams and SharePoint, with automatic expiration. Which solution should you implement?
A) Assign permanent guest accounts
B) Share resources via email
C) Azure AD B2B collaboration with expiration policies
D) Grant administrative privileges to external users
Answer: C
Explanation:
A Permanent guest accounts pose a security risk because external users retain access indefinitely. Without expiration, it becomes difficult to manage permissions and enforce least privilege, increasing the likelihood of data leakage.
B Sharing resources via email does not provide controlled access, audit logs, or automated expiration. It exposes sensitive documents to unauthorized sharing and lacks the governance required for corporate security policies.
C Azure AD B2B collaboration enables secure access for external users while leveraging their existing credentials. Expiration policies allow access to automatically terminate after a defined period, such as the duration of a project. SC-300 candidates should understand how to configure B2B invitations, set expiration dates, and enforce MFA and device compliance through Conditional Access. Combining B2B collaboration with Access Reviews allows organizations to validate ongoing necessity of access and maintain strong governance. This approach aligns with zero-trust principles, reducing administrative overhead and ensuring external collaboration does not compromise internal security. Audit logs provide visibility into external user activity, supporting compliance with organizational and regulatory requirements. Automated access revocation ensures that once the project ends or the consultant leaves, their access is removed without manual intervention, maintaining operational efficiency and security.
D Granting administrative privileges to external users is unnecessary and creates significant security risks. It violates least privilege principles and can expose critical organizational.
Question 89
You need to enforce MFA only for users signing in from high-risk IP addresses. Which solution is most effective?
A) Conditional Access with risk-based IP evaluation
B) Require MFA for all users
C) Assign Global Administrator roles for MFA enforcement
D) Enable Security Defaults only
Answer: A
Explanation:
A Conditional Access with risk-based IP evaluation allows MFA to be enforced dynamically based on the context of the sign-in, including IP reputation, location, and device compliance. SC-300 candidates should understand how to create policies that trigger MFA only for high-risk scenarios, minimizing user friction while maintaining strong security. Integrating this feature with Azure AD Identity Protection enables real-time analysis of risky sign-ins, adaptive authentication challenges, and automatic remediation. This solution supports zero-trust principles, continuously validating identity before granting access to sensitive resources. Detailed reporting and auditing provide visibility into access patterns and policy effectiveness, which is essential for regulatory compliance and internal governance. Organizations can combine this with Access Reviews to ensure ongoing validation of access and reduce potential attack surfaces.
B Requiring MFA for all users improves overall security but is less user-friendly, applying the challenge even in low-risk scenarios, which can reduce efficiency.
C Assigning Global Administrator roles to enforce MFA manually is inefficient, does not scale, and cannot dynamically respond to risk levels, making it unsuitable for targeted protection.
D Security Defaults provide basic protection but cannot evaluate risk or contextual information, preventing adaptive enforcement and granular policy application.
Question 90
You need to automatically assign Azure AD roles and group memberships based on user attributes without manual intervention. Which feature should you use?
A) Dynamic groups with attribute-based membership rules
B) Manual role assignment
C) Enable Security Defaults only
D) Require MFA without role assignment
Answer: A
Explanation:
A Dynamic groups in Azure AD automatically manage user memberships based on attributes such as department, job title, or location. SC-300 candidates should know how to define membership rules using logical operators and attributes to ensure users are assigned the correct roles and group memberships. This reduces manual errors, supports least privilege principles, and ensures compliance with governance standards. Combining dynamic groups with Access Reviews allows organizations to periodically validate user access, maintaining a secure environment. Additionally, integration with Conditional Access policies ensures that access to critical resources is enforced according to real-time contextual signals. By leveraging dynamic groups, administrators can automate access management, adapt to role changes, and quickly remove access when employees leave, which is crucial in large organizations with frequent personnel changes.
B Manual role assignment is time-consuming, error-prone, and does not scale effectively. Users may retain access unnecessarily, increasing the risk of privilege creep.
C Security Defaults enforce baseline protections but do not provide automatic role or group assignments based on user attributes, limiting operational efficiency.
D Requiring MFA improves authentication security but does not automate role or group assignment, leaving access management inconsistent and prone to errors.
Question 91
You need to require multi-factor authentication for users accessing financial applications only if they are signing in from unmanaged devices. Which method should you implement?
A) Assign permanent administrative roles
B) Security Defaults
C) Conditional Access policies with device compliance rules
D) Require MFA for all users
Answer: C
Explanation:
A Assigning permanent administrative roles does not enforce authentication requirements for end-users. Roles manage permissions but do not provide context-aware MFA enforcement. Using this approach could create security gaps because it does not differentiate between managed and unmanaged devices or evaluate user risk.
B Security Defaults enable baseline protections, such as requiring MFA for all users, but they are rigid and lack the flexibility to evaluate device compliance. They cannot enforce MFA selectively based on device type or compliance status, making them unsuitable for scenarios requiring granular control.
C Conditional Access policies with device compliance rules are ideal for enforcing MFA selectively. SC-300 candidates should understand how to configure policies to evaluate whether a device is managed and compliant with organizational standards, such as Intune enrollment, endpoint protection, or encryption policies. When a user attempts to access financial applications from an unmanaged device, the Conditional Access policy triggers MFA or blocks access based on configured rules. This approach aligns with zero-trust principles, ensuring that sensitive resources are only accessed under secure conditions. Additionally, policies can integrate with Azure AD Identity Protection to evaluate risk scores and enforce adaptive authentication. Reporting and auditing provide insights into user access patterns, device compliance levels, and policy enforcement, which are critical for regulatory compliance and governance. Using device-compliant Conditional Access reduces administrative overhead, improves security posture, and enhances user experience by avoiding unnecessary MFA prompts on trusted devices.
D Requiring MFA for all users enforces strong authentication but lacks context awareness, forcing unnecessary challenges for trusted, compliant devices, and reducing user convenience.
Question 92
You need to ensure external contractors have temporary access to SharePoint and Teams for a project with automatic expiration. Which solution should you implement?
A) Assign permanent guest accounts
B) Share resources via email links
C) Azure AD B2B collaboration with access expiration policies
D) Assign administrative roles to external users
Answer: C
Explanation:
A Permanent guest accounts pose a significant security risk because contractors maintain access indefinitely. This increases exposure to sensitive data and violates least privilege principles. Manual revocation is error-prone and may be delayed, creating potential compliance issues.
B Sharing resources via email links is insecure because it lacks granular control, auditing, and automated expiration. Recipients can forward links, creating uncontrolled access to confidential documents. This method does not comply with enterprise security governance.
C Azure AD B2B collaboration with access expiration policies allows secure temporary access for external users. SC-300 candidates should understand how to configure invitations, define expiration dates, and enforce MFA or device compliance via Conditional Access policies. When the project ends, access is automatically revoked, maintaining security and compliance. Additionally, Access Reviews can periodically validate ongoing access needs. B2B collaboration also integrates with auditing and reporting capabilities to provide visibility into external user activity. This solution adheres to zero-trust principles, reduces administrative overhead, and prevents potential data breaches by limiting access duration.

A) Security Defaults
B) Conditional Access policies with location-based rules
C) Require MFA for all users
D) Assign Global Administrator roles
Answer: B
Explanation:
A Security Defaults enforce baseline security measures but cannot differentiate sign-ins based on geographic location. They lack the flexibility required to block or allow specific countries.
B Conditional Access policies with location-based rules provide granular control over sign-ins based on IP ranges or countries. SC-300 candidates should know how to define trusted IP ranges and configure policies that block access from untrusted locations. Integration with Azure AD Identity Protection enables evaluation of user risk and contextual access control. This approach enhances security by preventing unauthorized sign-ins from regions where the organization has no operations. Reporting and auditing provide insights into blocked attempts, aiding compliance with security standards. Location-based Conditional Access supports zero-trust principles by continuously evaluating context before granting access, ensuring that only legitimate users from trusted locations can access resources. It reduces risk while maintaining usability for users in allowed regions.

A) Require MFA for all users
B) Security Defaults
C) Conditional Access policies with risk-based sign-in detection
D) Assign permanent administrative roles
Answer: C
Explanation:
A Requiring MFA for all users enforces strong authentication but does not differentiate between low-risk and high-risk sign-ins, causing unnecessary friction and inefficiency.
B Security Defaults enforce basic MFA for all users but cannot respond dynamically to sign-in risk levels or contextual threats, making them unsuitable for adaptive security.
C Conditional Access policies with risk-based sign-in detection integrate with Azure AD Identity Protection to evaluate sign-ins in real time. SC-300 candidates should understand how to create policies that require MFA only when a sign-in is considered high-risk based on signals such as atypical location, unfamiliar device, or sign-in behavior anomalies. This approach implements adaptive security, aligning with zero-trust principles, and ensures a balance between user experience and protection. Audit logs provide visibility into risky sign-ins, policy triggers, and mitigation actions, supporting compliance and security governance. Access Reviews can periodically validate ongoing access for high-risk users, enhancing operational efficiency and security posture. This approach allows organizations to enforce conditional MFA dynamically, protecting sensitive resources while minimizing disruption for low-risk scenarios.
D Assigning permanent administrative roles does not address risk-based authentication and cannot automate adaptive MFA enforcement.
Question 95

A) Assign permanent guest accounts manually
B) Azure AD B2B collaboration with access expiration policies
C) Share files via unsecured email links
D) Grant administrative privileges to external users
Answer: B
Explanation:
A Assigning permanent guest accounts manually introduces significant security risks. External users retain access indefinitely unless manually removed, which is error-prone and time-consuming. It violates least privilege principles and creates potential for unauthorized access to sensitive resources. Administrators would need to track expiration dates manually, increasing operational complexity and the risk of human error. This method is unsuitable for large-scale projects with multiple external collaborators.
B Azure AD B2B collaboration with access expiration policies provides a secure and automated way to manage external access. By configuring access expiration policies, organizations can ensure that vendors automatically lose access after a set period, such as 90 days. SC-300 candidates should understand how to create B2B invitations, enforce Conditional Access policies for security, and integrate Access Reviews to periodically validate external user access. This approach minimizes administrative overhead while ensuring compliance with organizational security standards. Using B2B collaboration, external vendors authenticate with their own identity providers, reducing password management issues, while administrators maintain visibility into their activities. Reports and audit logs track access events, supporting regulatory compliance and internal governance. Additionally, Conditional Access policies can enforce multi-factor authentication (MFA) and device compliance, further enhancing security. This solution aligns with zero-trust principles by ensuring that external users have access only as long as needed and only under secure conditions.

C Sharing files via unsecured email links lacks control, auditing, and expiration capabilities. Users can forward links outside the intended audience, creating significant security vulnerabilities. This method does not support enterprise governance standards.
D Granting administrative privileges to external users is highly risky and unnecessary. It exposes sensitive administrative capabilities, violating least privilege principles and increasing the potential for accidental or malicious changes to the environment.
Question 97
You need to block all legacy authentication attempts while allowing modern authentication for users. Which Azure AD feature should you use?
A) Conditional Access policies with legacy authentication exclusion
B) Security Defaults only
C) Require MFA for all users
D) Assign permanent administrative roles
Answer: A
Explanation:
A Conditional Access policies allow administrators to block legacy authentication protocols while permitting modern authentication. SC-300 candidates should know how to configure policies to target legacy protocols, such as POP, IMAP, or SMTP, while allowing secure, modern authentication methods like OAuth 2.0 or SAML. Blocking legacy authentication reduces the attack surface because these older protocols cannot enforce MFA or conditional access, making them prime targets for password-based attacks. Policies can also be configured to exclude certain accounts, such as service accounts that require legacy authentication, balancing security and operational needs. Combining Conditional Access with Azure AD reporting ensures administrators can monitor blocked legacy sign-ins, track policy effectiveness, and adjust rules as needed. By implementing this approach, organizations enforce security without interrupting legitimate workflows, improving compliance with enterprise and regulatory security standards. This strategy is particularly important in large organizations where older protocols might still be in use by legacy systems, as it mitigates the risk of unauthorized access while supporting a smooth transition to modern authentication.
B Security Defaults block some legacy protocols and enforce baseline MFA but cannot be tailored for selective enforcement or exclusions, making them less flexible for enterprise scenarios.
C Requiring MFA for all users strengthens authentication but does not specifically block legacy authentication attempts, leaving vulnerabilities unaddressed.
D Assigning administrative roles does not block authentication protocols; it only governs permissions and access rights.
