   A telecommunications company has multiple billing systems that need to share a single customer master record. The MDM hub must push updates back to the billing systems whenever a customer's address changes, and the billing systems must also send updates to the hub. Which MDM implementation style best fits this requirement?

   • AConsolidation style, where the hub stores a merged record but does not write back
   • BCo-existence style, where the MDM hub synchronizes master data with source systems in both directions
   • CTransactional style, where the hub replaces the billing systems entirely
   • DRegistry style, where the hub stores only identifiers and pointers

   A logistics company wants to add geographic coordinates and regional classifications to its customer master data to optimize delivery routes. The company has customer addresses but no geocoding capability internally. Which approach should the data architect take?

   • ADerive coordinates from the customer's order history
   • BManually assign coordinates to each customer record in the MDM
   • CUse an external geocoding service to enrich the customer records with latitude, longitude, and regional classifications
   • DAdd coordinate fields to the canonical model and leave them empty
