Salesforce Platform Developer I (PDI) PDI Prüfungsfragen mit Lösungen (Q112-Q117):

112. Frage
A custom picklist field, Food _Preference_ c, exists on a custom object. The picklist contains the following options: 'Vegan', 'Kosher', 'No Preference'. The developer must ensure a value is populated every time a record is created or updated.
What is the optimal way to ensure a value is selected every time a record is saved?

A. Mark the field as Required on the object's page layout.
B. Write an Apex trigger to ensure a value is selected.
C. Set "Use the first value in the list as the default value" to True.
D. Mark the field as Required on the field definition.

Antwort: D

Begründung:
To ensure that the Food_Preference__c picklist field has a value every time a record is created or updated, marking the field as Required on the field definition is the optimal solution.
Option C: Mark the field as Required on the field definition
Universal Enforcement: Setting the field as required at the field level ensures that it must have a value regardless of how the record is created or updated (UI, API, data import).
Data Integrity: Prevents records from being saved without a value in the picklist field, maintaining data consistency.
No Additional Code: Achieves the requirement declaratively without the need for Apex code.
Reference:
Making a Custom Field Required
Why Other Options are Less Optimal or Incorrect:
Option A: Mark the field as Required on the object's page layout
UI Only: This setting only enforces the requirement when users interact with the record via the specific page layout.
Not Universal: Does not prevent records from being saved without a value through the API, data import, or other page layouts.
Option B: Set "Use the first value in the list as the default value" to True Default Value: Automatically populates the field on new records but does not prevent users from clearing the value.
No Enforcement on Updates: Does not enforce a value on record updates if the field is cleared.
Option D: Write an Apex trigger to ensure a value is selected
Unnecessary Complexity: Writing code for a requirement that can be met declaratively adds unnecessary complexity.
Maintenance Overhead: Triggers require testing and ongoing maintenance.
Best Practices: Prefer declarative solutions over programmatic ones when possible.
Conclusion:
Marking the Food_Preference__c field as Required on the field definition ensures that a value is always selected when a record is saved, across all contexts.
It is the most efficient and maintainable solution.

113. Frage
How does the Lightning Component framework help developers implement solutions faster?

A. By providing code review standards and processes
B. By providing change history and version control
C. By providing an Agile process with default steps
D. By providing device-awareness for mobile and desktops

Antwort: D

Begründung:
Answer A is 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: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer 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.

114. Frage

B. Match an auto-generated Number field to a column in the imported file.
C. Match the Id field to a column in the imported file.
D. Match the Name field to a column in the imported file.

Antwort: A,C

115. Frage
Which statement would a developer use when creating test data for products and pricebooks?

A. Id pricebookId = Test.getStandardPricebookId();
B. List objList = Test.loadData(Account.sObjectType, 'myResource');
C. Pricebook pb = new Pricebook();
D. IsTest(SeeAllData = false);

Antwort: A

116. Frage
Consider the following code snippet:

Given the multi-tenant architecture of the Salesforce platform, what Is a best practice a developer should Implement and ensure successful execution of the method?

A. Avoid executing queries without a limit clause.
B. Avoid returning an empty List of records.
C. Avoid using variables as query filters.
D. Avoid performing queries inside for loops.

Antwort: D
