To configure multi-factor authentication (MFA) for an Azure Virtual Desktop infrastructure, what is the best approach?

Creating a Conditional Access policy in Azure Active Directory (Azure AD) is indeed the best approach to configure multi-factor authentication (MFA) for an Azure Virtual Desktop infrastructure. Conditional Access policies allow administrators to enforce specific access controls based on user, device, location, and application context.

With Conditional Access, you can require MFA when certain conditions are met, such as when users attempt to access the Azure Virtual Desktop environment. This method is highly adaptable and can be tailored to various scenarios, providing a secure and user-friendly means to enhance authentication security.

This approach not only centralizes the authentication management within Azure AD but also ensures that MFA is consistently applied across the digital workspace, safeguarding sensitive data and resources.

In contrast, other options provided do not effectively facilitate MFA:

• Enabling Credential Security Support Provider (CredSSP) primarily enhances secure remote desktop protocol (RDP) connections but does not directly enable or manage multi-factor authentication.

• Configuring just-in-time (JIT) VM access on session hosts focuses on optimizing resource management and improving security by restricting access to virtual machines, but it does not implement MFA for user authentication.

• Setting up Pool1 as a Validation environment relates to testing configurations and settings rather than securing access through multi-factor authentication
