A company actively uses CI/CO processes for their Service Cloud implementation and is adding Marketing Cloud and Marketing Cloud Connect to their architecture. Under the current setup each developer has their own developer sandbox for development.
Developers merge their changes into a sandbox for QA regularly, then once every week changes are movedto staging, and from staging to production instances.
Which set up should a Solution Architect propose to support this development approach considering costs and data segregation?
A. Set up one Marketing Cloud instance with a business unit for productionand one business unit for testing that is connected to all Developer sandboxes
B. Set up one Marketing Cloud instance for testing and one for production, where the testing instance is connected to the staging sandbox
C. Set up one Marketing Cloud instancefor each sandbox in Service Cloud
D. Set up one Marketing Cloud instance for production and create a Marketing Cloud sandbox to connect to each of the Service Cloud sandboxes
D. Set up one Marketing Cloud instance for production and create a Marketing Cloud sandbox to connect to each of the Service Cloud sandboxes
Explanation: A Marketing Cloud sandbox is a separate instance of Marketing Cloud that can be used for development, testing, and training purposes. A Marketing Cloud sandbox can be connected to a Service Cloud sandbox using Marketing Cloud Connect, which allows data synchronization and cross-cloud functionality. This option supports the CI/CO processes and data segregation for each Service Cloud sandbox. The other options are either not feasible or not cost-effective.
