D. Kerberos authentication








 

Suggested Answer: B

You can create a Single-Page Application (SPA) which uses JavaScript to work with Microsoft Dataverse (Common Data Service) data. To provide this, Cross-
Origin Resource Sharing (CORS) is enabled so that your SPAs can bypass browser restrictions that normally prevent requests that cross domain boundaries.
