What is the function of the Configure action in synchronization?

The function of the Configure action in synchronization is to set up the synchronization configuration. This action is crucial because it allows developers to define how data synchronization will occur, including options such as which data to sync, how often to sync, and other settings that dictate the behavior and performance of the synchronization process. By establishing these configurations, developers ensure that the application behaves as expected during data exchanges between the client and the server.

Choosing this option highlights the importance of configuration in the synchronization process, setting the groundwork for efficient data management and improving user experience in the mobile application. The other choices deal with starting synchronization, deleting data, or modifying settings without focusing on the critical setup aspect, which is foundational for proper synchronization to occur.
