A large enterprise customer has decided to implement Salesforce as their CRM.

Option C is correct because Salesforce should be the system of record for their customers and prospects, as it is the CRM solution that the sales and service associates use to view and log their interactions with them. Salesforce can also integrate with the Marketing and ERP solutions to display relevant information from those systems, such as campaign history, invoices, and orders12

Option A is incorrect because ERP is not a suitable system of record for customers and prospects, as it is mainly focused on invoicing and order fulfillment. ERP may not have all the data that the sales and service associates need to interactwith them, such as contact details, preferences, activities, and opportunities. ERP may also have different datamodels and definitions than Salesforce and Marketing, which can cause data quality and consistency issues3

Option B is incorrect because Marketing is not a suitable system of record for customers and prospects, as it is mainly focused on email campaigns. Marketing may not have all the data that the sales and service associates need to interact with them, such as account information, service cases, contracts, and quotes. Marketing may also have different data models and definitions than Salesforce and ERP, which can cause data quality and consistency issues.

Option D is incorrect because creating a new custom database for customers and prospects is not a feasible orefficient solution, as it would require additional development, maintenance, and integration costs. It would also create another layer of complexity and potential data duplication in the system landscape. Salesforce already provides a robust and flexibleplatform for managing customer and prospect data, which can be easily customized and integrated with other systems.
