Which Blocks are essential for offline interactions in OutSystems?

The correct answer highlights the importance of specific blocks in enabling offline interactions within OutSystems applications. The NetworkStatusChanged block is essential as it notifies the application when the network status changes, allowing the application to respond accordingly when the device transitions between online and offline states. This capability is vital in ensuring a seamless user experience as it enables the application to manage data synchronization effectively when the network becomes available again.

The OfflineDataSyncCore block is crucial for handling the logic behind data synchronization when the application is back online. This block manages the background sync process, ensuring that any data collected while offline is correctly uploaded to the server, maintaining data integrity and consistency.

Combining these two blocks makes it possible to create a robust offline experience, as they work together to manage the app's behavior in different network scenarios and ensure that user interactions while offline are not lost or overlooked.

Other choices may present blocks that are useful but do not pair the same essential functionalities for handling offline interactions and synchronization effectively. For example, while SyncStatus and other blocks are relevant, they do not encapsulate the necessary functionality as effectively as the correct choice.
