Cloud Kicks' (CK) VP of technology wants to start using Salesforce for all the sales team's automation. CK migrated 70 million records from a legacy database to the datawarehouse that will be synced with Salesforce. CK wants to search and cross-reference records with the original source database. What should a consultant recommend meeting this requirement?
Correct Answer: B
Explanation This is the recommended solution for Cloud Kicks if they want to search and cross-reference records with the original source database after migrating 70 million records from a legacy database to the data warehouse that will be synced with Salesforce. Using a custom External ID field and mapping it to the source record ID value will allow Cloud Kicks to uniquely identify each record and match it with its corresponding record in the source database. A custom External ID field is a custom field that has the External ID attribute enabled, which means that it can be used as a unique identifier for data import or integration purposes.
