The Sync Type allows switching between PUSH or POLL (default) synchronization types in an application link. PUSH must be enabled when the external application is configured to push record change messages to ConnectALL instead of having ConnectALL poll the application for modifications. See ReST API for more information on PUSH. Depending on the application's capabilities, ConnectALL will do both read and write on the side configured for PUSH, using that application's API. The only difference is the switch from polling to event-driven synchronization.

The Sync Operations represent the configurations of the synchronization direction at the application level. By default, both create & update will be selected in both applications. If any of the create/update events need to be prevented in the application, uncheck the options, this will prevent the event during synchronization to the application.
