                                                                          Box 1: Yes

Delta query enables you discover changes to users without having to fetch the entire set of users from Microsoft Graph and compare changes.
                                                                          Box 2: No

                                                                          Tracking user changes is a round of one or more GET requests with the delta function. You make a GET request much like the way you list users, except that you include the following:
                                                                          The delta function.
                                                                          A state token (deltaToken or skipToken) from the previous GET delta function call.
                                                                          Delta tokens are only valid for a specific period before the client application needs to run a full synchronization again. For directory objects (application, administrativeUnit, directoryObject, directoryRole, group, orgContact, oauth2permissiongrant, servicePrincipal, and user), the limit is 7 days.
                                                                          Box 3: No
                                                                          There is limited support for $filter:

                                                                          Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
                                                                          After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
                                                                          A Common Data Service (CDS) environment has two custom entities named Building code and Work item.
                                                                          Building code has a code date custom field and Work item has an elapsed time custom field. Construction workers use a consolidated custom form with data from both entities to fill.in their daily work items.
                                                                          A JavaScript library is used with these custom entities and fields to apply complex logic.
                                                                          You need to ensure that the JavaScript library continues to function as originally designed if other developers expand the environment.
                                                                          Solution: In form properties of the consolidated form, add the JavaScript library in the events tab and add the two custom fields to the dependent fields section of the non-event dependencies tab.
                                                                          Does the solution meet the goal?
