   A multinational bank operates a three-site ECS federation with asynchronous geo-replication. They are experiencing data conflicts when the same object is updated at two sites simultaneously. The bank wants to minimize data loss and ensure that the most recent update is preserved. What is the best approach to handle these conflicts?

   • AManually resolve conflicts by comparing object versions at each site
   • BRely on ECS's default last-writer-wins conflict resolution based on timestamps
   • CConfigure the federation to use synchronous replication between all sites
   • DDisable geo-replication to prevent conflicts from occurring
