Salesforce Certified Data Architect — Question 68

Universal Containers (UC) has the following systems:
1. Billing system
2. Customer support system
3. CRM system
UC has been having trouble with business intelligence across the different systems. Recently UC implemented a master data management (MDM) solution that will be the system of truth for the customer records.
Which MDM data element is needed to allow reporting across these systems?

Answer options

• A. Phone number
• B. Email address
• C. Full name
• D. Globally Unique Identifier

Correct answer: D

Explanation

The correct answer is D, the Globally Unique Identifier, because it provides a unique reference for each customer across all systems, enabling accurate reporting and data integration. The other options, while useful, do not guarantee uniqueness across different records in various systems, which is crucial for effective business intelligence.
