Exam PL-400 topic 7 question 23 discussion

Correct Options: Microsoft Authentication Library (MSAL): MSAL is the recommended library for modern authentication in web applications, supporting OAuth2 and the Microsoft identity platform. It will handle authentication using Azure AD and OAuth, meeting the requirement for "OAuth without additional verification." Microsoft Azure Active Directory Authentication Libraries (ADAL): ADAL is the previous authentication library, but it still supports OAuth authentication for web applications. However, MSAL is the preferred solution now, as ADAL is being deprecated in favor of MSAL.

C, D Although ADAL has been deprecated and Microsoft recommends migrating the MSAL https://learn.microsoft.com/en-us/entra/identity-platform/msal-migration

Both ADAL and MSAL are libraries provided by Microsoft for enabling OAuth authentication in applications. ADAL (Azure Active Directory Authentication Libraries) and MSAL (Microsoft Authentication Library) are used for implementing OAuth authentication flows with Azure Active Directory (Azure AD). They provide capabilities for securely obtaining tokens from Azure AD to authenticate users and enable access to protected resources like the Web API provided by the model-driven app.

ADAL has been decommissioned as of June 2023

Looks correct to me.
