A customer has been using Marketing Cioud with their existing (non-Salesforce) ecommerce site for more than 3 years and is now implementing Service Cloud to help improve the quality of support given to their customers. While Service Cloud will be integrated with the ecommerce site and they want to use many Marketing Cloud Connect features, the customer is insisting on continuing to use the existing integration between the ecommerce site and Marketing Cloud until they move to Salesforce B2C Commerce (planned for the coming 2 years).

Which two concerns should the Solution Architect raise with the customer considering the approach they want to take?

Choose 2 answers

A. Additional Matching rules will need to be implemented in Service Cloud to ensure identities are merged before messaging in Marketing Cloud.

B. Email tracking for messages sent from theecommerce site will not be replicated via Marketing Cloud Connect and therefore will not be visible to the Service Agents.

C. Journey Builder will need to be used to update the Contact Key directly in Marketing Cloud to ensure the existing ecommerce siteintegration can continue to be used.

D. Contacts may be duplicated in Marketing Cloud during the transition phase, and additional work may be required to merge identities at a later date.
