Microsoft Azure Architect Design (AZ-301) Practice Exam

What should you implement to authenticate users at Contoso for cloud-based services while using Azure AD?

1. Pass-through Authentication

2. Federation with AD FS

3. Password Synchronization

4. Security Assertion Markup Language (SAML) Authentication

The correct answer is: Pass-through Authentication

Implementing Pass-through Authentication is an effective method for authenticating users for cloud-based services in an environment such as Contoso using Azure Active Directory (Azure AD). This approach allows users to access both on-premises and cloud resources using the same passwords they utilize for their on-premises Active Directory accounts without needing to store passwords in the cloud. The authentication process operates smoothly by validating the credentials against the on-premises Active Directory during login attempts, ensuring that the security and compliance requirements are upheld while providing a seamless user experience. Pass-through Authentication also allows for a less complex setup compared to other methods, as there is less configuration involved in terms of maintaining additional servers or services. In contrast, Federation with AD FS involves a more extensive implementation and means setting up an Active Directory Federation Services server, requiring additional maintenance and resources. Password Synchronization is another reliable option but introduces the need for storing passwords in the cloud, which may raise security concerns depending on the organization's policies. SAML Authentication, while a widely used standard for authenticating users across different applications, is not as directly relevant for establishing authentication with Azure AD in the same way as Pass-through Authentication. Overall, choosing Pass-through Authentication aligns well with requirements for ease of use, security, and
