Answer 1

For SQL Server you can use Merge Replication for this. Or you code your application to handle the synchronization, writing to a local database, detecting when you have connectivity, and copying data back and forth to the central database.

The choice really comes down to how many tables need to be synced, whether you have bi-directional tables, and whether you need automatic conflict detection and resolution.

So, if you have only a few tables to replicate, and they are all either download-only, or upload-only then just write this as part of your application.
