Salesforce Certified B2B Solution Architect (Arch-301) Exam - Topic 2 Question 69 Discussion

Posted by Dorthy on May 06, 2026 at 06:57 AM

Universal Containers (UC) is undergoing a multi-year digital transformation across its Sales, Marketing, Fulfillment, and Accounting channels. Based on UC's initial success using MuleSoft's API-led approach as its integration strategy, UC chose Salesforce for its transformation. The Solution Architect assigned to the project has just begun pre-planning for the first phase with UC's Implementation team.

Which document should the Solution Architect ask for to get an overview of the customer's current infrastructure so they can begin the first phase of the digital transformation?

Suggested Answer: C

a reference architecture diagram is a document that shows the high-level view of the customer's current infrastructure, including the systems, applications, data sources, integrations, and security layers. A reference architecture diagram also indicates which system is the system of record for each data entity and how data flows between systems.

A reference architecture diagram is useful for a Solution Architect to get an overview of the customer's current infrastructure so they can begin the first phase of the digital transformation. A reference architecture diagram can help identify gaps, risks, dependencies, and opportunities for improvement in the existing landscape. It can also serve as a baseline for designing future state solutions that leverage Salesforce products and features.
