📝 Sample Platform App Builder Questions
💡 Scenario-Based & Clicks-Not-Code Focus
The exam uses realistic business scenarios. Pay attention to keywords like “Admin wants to avoid code”, “future scalability”, “different page layouts per profile”, or “different lifecycle per region”.
Question 1: Data Model
A company needs to track projects and the many employees who work on each project. Each employee can work on multiple projects. The Admin must capture each employee’s role and allocation % per project. How should the data model be designed?
A) Add a multi-select picklist “Employees” on Project.
B) Create a junction object between Project and Employee.
C) Create a text field “Projects” on User to list all projects.
D) Use a hierarchical relationship on Project.
✓ Correct Answer: B) Create a junction object between Project and Employee.
Explanation: A many-to-many relationship with extra fields (role, allocation %) requires a junction object that has two master-detail relationships: one to Project and one to Employee.
Question 2: Validation vs Automation
Sales reps must enter a discount reason when the Opportunity Discount % is greater than 30%. What is the best declarative solution?
A) Workflow rule to send an email when the discount is high.
B) Validation rule requiring Discount Reason when Discount % > 30.
C) Approval process when Discount % > 30.
D) Checkbox field “High Discount” updated by a scheduled flow.
✓ Correct Answer: B) Validation rule requiring Discount Reason.
Explanation: Validation rules enforce data quality at save time. When a field must be filled based on another field’s value, a validation rule is the simplest and most maintainable solution.
Question 3: Flow Choice
When an Opportunity is closed won, the system must automatically:
• Create a custom “Implementation Project” record
• Create Tasks for the project team
• Send a Slack notification to the implementation channel (via an existing outbound integration)
What is the recommended automation tool?
A) Record-triggered Flow on Opportunity.
B) Workflow Rule with field update and email alert.
C) Scheduled Flow that runs nightly.
D) Manual quick action for the sales team.
✓ Correct Answer: A) Record-triggered Flow on Opportunity.
Explanation: Record-triggered flows are the recommended tool for automating related record creation and integrations when a record meets criteria (like Stage = Closed Won).
Question 4: UI Design
Support agents complain that the Case page is cluttered and scroll-heavy. They only need certain fields while working on open cases. What should the App Builder do to improve the experience using Lightning App Builder?
A) Remove fields from the page layout for all profiles.
B) Create a new Lightning record page with tabs and conditional visibility.
C) Ask users to create custom list views instead.
D) Enable in-app guidance for Case.
✓ Correct Answer: B) New Lightning record page with tabs & conditional visibility.
Explanation: Lightning record pages allow you to group fields into tabs/sections and show or hide components based on record criteria or user details, improving usability without removing fields from the underlying layout.
Question 5: Deployment
An App Builder has created a new custom object with record types, page layouts, validation rules, and flows in a sandbox. They now want to deploy the configuration to production. Which approach is recommended?
A) Recreate all configuration manually in production.
B) Use an outbound change set from sandbox to production.
C) Export all metadata via Data Loader and import to production.
D) Use a scheduled flow to replicate metadata.
✓ Correct Answer: B) Use an outbound change set.
Explanation: For declarative configuration between related orgs, change sets are the standard way to move metadata from sandbox → production without rebuilding everything.
💡 Exam Tip: Many questions offer both a “works” option and a best-practice option. Always prefer solutions that are scalable, declarative, and easy to maintain (Flows, proper data models, change sets) over quick hacks.
📚 Study Plan for Platform App Builder (3–6 Weeks)
🎯 Suggested Roadmap
Review Salesforce basics, licenses, and navigation. Build or refactor a data model with custom objects, relationships, record types, and fields in a Developer Edition org.
Implement several record-triggered flows, validation rules, and approval processes for real scenarios (lead qualification, opportunity approvals, case escalations).
Build custom Lightning record pages, dynamic forms, and actions. Practice moving changes between sandboxes using change sets.
Take full-length practice exams in timed conditions. For every wrong answer, find the concept in docs/Trailhead, then rebuild a small example in your org.
💡 Exam Day Tips (Platform App Builder)
60 questions in 105 minutes ≈ ~1.75 minutes per question. Don’t spend more than 2–2.5 minutes on any single question. Use the mark for review feature.
Prefer solutions that are scalable, secure, and maintainable. If code is an option, but a clean declarative solution exists, the exam usually favors the declarative one.
Terms like “must be required”, “without code”, “multiple processes”, or “different user groups” often point to specific tools (validation rules, flows, record types, or page layouts).
❓ Platform App Builder – Frequently Asked Questions (FAQ)
Is Platform App Builder the same as the Administrator certification?
No. The Administrator cert focuses on managing an org (users, security, standard features). Platform App Builder focuses on designing & building custom apps using declarative tools: data model, automation, and UI. Many people do Admin first, then App Builder as the next step.
Do I need coding (Apex) experience to pass this exam?
No. The exam is focused on clicks, not code. You may see questions that mention Apex or APIs at a high level, but you are not expected to write code. You should, however, know when a requirement cannot be met declaratively and might need programmatic solutions.
How much experience do I need before attempting Platform App Builder?
Salesforce recommends around 6–12 months of hands-on experience building apps on the platform: creating custom objects, fields, record types, flows, and Lightning pages. The more real projects you’ve worked on, the easier the scenario questions will feel.
How does Platform App Builder compare to Platform Developer I?
Platform App Builder = deep on declarative tools and solution design. Platform Developer I = focuses on Apex, triggers, and Lightning Web Components. Many candidates use App Builder as a bridge: first learn to solve problems with clicks, then fill gaps with code in PD1.
How do I keep my Platform App Builder certification active?
Salesforce periodically releases maintenance modules on Trailhead. You’ll get an email when a maintenance is due. Complete the short quiz by the deadline to keep your certification in good standing.
