Salesforce Platform Developer PDI & PDII: Practice Tests

Pass PDI & PDII Exams | Apex, Triggers, SOQL, LWC, Governor Limits, Flows, REST APIs & 300+ Mock Questions

Salesforce is the world's number one CRM platform — used by over 150,000 companies globally, from lean startups to the Fortune 500. Salesforce-certified developers are among the highest-paid professionals in the tech industry, with Platform Developer certification holders consistently commanding salaries and contract rates that outpace most comparable credentials. In a Salesforce ecosystem where companies spend millions on implementations, employers and clients cannot afford to hire developers who cannot prove their platform expertise.

The Salesforce Certified Platform Developer credential is your proof. This practice test course is built to get you there. It contains 300 exam-style questions organized into four full-length timed tests of 75 questions each — precisely engineered to match the difficulty, format, and topic weighting of the official Salesforce Platform Developer certification exam.

Every question includes a detailed explanation of the correct answer and each wrong option — because the Salesforce exam is known for scenario-based questions where multiple answers appear correct until you apply the right governor limit, best practice, or platform constraint. Topics cover the full certification blueprint: Apex fundamentals and governor limits, SOQL and SOSL queries, triggers and trigger frameworks, asynchronous Apex (Batch, Queueable, Future, Scheduled), Lightning Web Components, Visualforce, platform events, declarative vs programmatic solutions, testing with Apex test classes, deployment with change sets and Salesforce DX, and security model best practices.

The timed format trains the exam-day decision speed and scenario reasoning that Salesforce's multi-layered questions demand. Four complete practice tests generate a precise, topic-by-topic diagnostic profile so you allocate your final study time exactly where it converts to marks.

Whether you are a first-time candidate or closing the gap after a previous attempt, this course is the sharpest, most targeted Salesforce Platform Developer preparation available. Enroll today, take your first test, and find out exactly where you stand.

  • Working experience with Salesforce development — you should have built Apex classes, triggers, or LWC components in a Salesforce org, sandbox, or developer edition
  • Familiarity with SOQL query syntax and Salesforce's standard and custom object model — including relationships, lookups, and master-detail structures
  • Basic understanding of Salesforce declarative tools — Flow, Process Builder, validation rules, and when to choose declarative over programmatic solutions
  • Ideally, completion of Salesforce Administrator certification or Trailhead Superbadges related to Apex and LWC — though motivated candidates with hands-on experience can succeed without them
  • Write and optimize Apex code within Salesforce governor limits — understanding SOQL in loops violations, heap size management, CPU time limits, and bulkificatio
  • Design and implement Apex triggers using best-practice trigger frameworks — one trigger per object, handler classes, recursion prevention, and context variable
  • Build and deploy asynchronous Apex solutions — Batch Apex, Queueable Apex, Future methods, Scheduled Apex, and Platform Events — selecting the right pattern for
  • Develop Lightning Web Components (LWC) — component lifecycle, wire service, imperative Apex calls, component communication, and event handling in Salesforce's m
  • Apply Salesforce security model and sharing rules — object and field-level security, record sharing, with sharing / without sharing keywords, and how security i
  • Evaluate personal exam readiness through four timed, full-length practice tests with per-topic diagnostic feedback to direct final preparation with precision
  • Salesforce developers and admins preparing for the official Platform Developer I or II certification who want realistic, scenario-based practice before sitting the real exam
  • Salesforce Administrators pursuing a developer path who already hold the Admin cert and are ready to move into programmatic development with a formal credential to match
  • Java, JavaScript, or Python developers joining Salesforce projects who need to validate their Apex and LWC skills with an official Salesforce credential recognized by implementation partners and clients
  • Salesforce consultants and implementation partners at firms like Accenture, Deloitte, Cognizant, or boutique ISVs who need the Platform Developer cert to maintain partner tier status or qualify for client engagements
  • Candidates who previously attempted the Platform Developer exam and need precise diagnostics to identify and close the specific gaps — particularly governor limits, async patterns, and security model — that caused the miss
