A casino is implementing Salesforce and is planning to build a customer 360 degree view for a customer who visits its resorts. The casino currently…

Exploring external data sources in Salesforce to build a 360 degree view of the customer (option A) is

the best strategy to satisfy this requirement, as it allows customer service agents to view the

activities from all four systems in real time without storing or replicating the data in Salesforce. Using

a customer data mart to create the 360 degree view of the customer (option B) is not a good

strategy, as it may introduce additional complexity and cost, and it does not leverage the native

Salesforce features. Periodically uploading summary information in Salesforce to build a 360 degree

view (option C) is also not a good strategy, as it may cause data latency and inconsistency, and it does

not provide real-time information. Migrating customer activities from all four systems into Salesforce

(option D) is also not a good strategy, as it may cause data redundancy and conflicts, and it does not

scale well with large volumes of data.
