Question 1
Q1A system architect is explaining how custom applications can be built on the Salesforce Platform. They describe a layered architecture where the core services are shared, but each application has its own declarative and programmatic components. Which layer in this model is primarily responsible for defining the structure of custom objects, fields, and relationships?

Show answer & explanation
Correct answer: C
The power of the Salesforce platform lies in its metadata-driven architecture. The Metadata Layer defines the structure of the data model (objects, fields, relationships) and the security model. Platform Services use this metadata to render the UI and execute logic, while the Core Infrastructure hosts everything in a multitenant environment.
