Salesforce Certified Platform Developer I

Salesforce · advanced · 105 minutes

Update in progressSalesforce now publishes this exam as Platform Developer, four sections, questions aligned to Summer 25; our bank was written for PD I as two broad domains with the release-version excuse, checked on 21 September 2026. The questions still teach the subject, but the split per domain has moved.

Programmatic development on the platform: Apex with the sharing keywords that govern records but not fields, SOQL relationship queries and partial-success DML, the governor limits that follow from multitenancy and the bulkification they demand, and triggers with one per object delegating to a handler; then the four asynchronous mechanisms and when each applies, Lightning Web Components with reactivity and the wire service, testing that creates its own data and asserts rather than merely executes, and deployment where all tests run.
