Customer 360 Data Manager is a platform service that enables companies to connect customer data

across Salesforce apps and create a unified customer profile. It uses advanced matching algorithms to

identify and link customer records from different systems based on common attributes such as

name, email, phone, address, etc. It also assigns a consistent Global Party ID to each customer

record, which serves as a unique identifier across systems. Customer 360 Data Manager can be used

across multiple brands within a single merchant environment by creating separate data spaces for

each brand. Option B is incorrect because Customer 360 Data Manager can relate the IDs between

systems without additional custom development. Option C is incorrect because Customer 360 Data

Manager supports multiple brands within a single merchant environment. Option D is incorrect

because B2C Commerce, Service Cloud, and Marketing Cloud do not automatically use a common

core Customer Profile managed by Customer 360 Data Manager; they need to be connected and

configured via Customer 360 Data Manager. Reference:
