B2C-Solution-Architect - Salesforce Certified B2C Solution Architect(SP23)

• Option A is correct because running load testing in B2C Commerce pre-launch against the production instance connected to a full copy sandbox in Service Cloud is a recommended practice to ensure that the multi-cloud solution can handle the expected traffic and transactions without compromising performance or functionality.
• Option C is correct because using a single Marketing Cloud instance to connect to multiple Service Cloud environments using Marketing Cloud Connect for each business unit is a recommended practice to enable data synchronization and integration between the clouds without duplicating data or creating conflicts.
• Option B is incorrect because using Marketing Cloud business units as testing environments is not a recommended practice, as it may cause data quality issues, security risks, and configuration challenges. Marketing Cloud business units should be used for segmentation and personalization purposes, not for testing or development.
• Option D is incorrect because using a Service Cloud partial copy sandbox to provide better performance than a developer pro sandbox as well as a normal sandbox is not a valid statement, as partial copy sandboxes have the same performance characteristics as developer pro sandboxes and normal sandboxes. The main difference between partial copy sandboxes and other types of sandboxes is the amount of data they can store.

The Secondary Instance Group is used for sandboxes in B2C Commerce. Adding new sandboxes to this group does not require creating a new realm or adding instances to the Primary Instance Group, which is used for production and staging instances.
