What should you do?

You are developing an application that will track changes to the UserPrincipalName attribute of Microsoft 365 accounts.

You need to use a REST request to retrieve the information by using Microsoft Graph. The solution must minimize the amount of data retrieved.

What should you do?
A . Use GET https://graph.microsoft.com/v1.0/users/delta for the first call. Use the state token in subsequent calls.
B . Use GET https://graph.microsoft.com/v1.0/users/delta?$select=UserPrincipalName for the first call. Use the state token in subsequent calls.
C . Use GET https://graph.microsoft.com/v1.0/users$select=UserPrincipalName for the calls and track the changes.
D . Use GET https://graph.microsoft.com/v1.0/users for the calls and track the changes.

Answer: B

Explanation:

Use delta query to track changes in a resource collection

The typical call pattern is as follows: application begins by calling a GET request with the delta function on the desired resource.

✑ The Graph sends a response containing the requested resource and a state token.

Example: Selecting three properties

The next example shows the initial request selecting three properties for change tracking, with default response behavior.

Note: Delta query enables applications to discover newly created, updated, or deleted entities without performing a full read of the target resource with every request.
