Exam PDI Topic 1 Question 150 Discussion

Answers B, C are correct. The Salesforce Platform favors metadata-driven design where possible and Apex or custom UI when requirements exceed declarative capability. Correct design means selecting the lowest- maintenance platform feature that satisfies security, data integrity, scalability, and user experience requirements while remaining compatible with Salesforce's multi-tenant runtime model. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Salesforce Apex Developer Guide, SOQL and SOSL Reference, Flow Builder Help, and Apex Reference Guide. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points. This matters on the Salesforce platform because the same logic can run from the user interface, API operations, imports, and background automation.
