Salesforce Platform Developer I (PDI) Sample Questions (Q122-Q127):

NEW QUESTION # 122
A developer created a trigger on a custom object. This custom object also has some dependent pick lists.
According to the order of execution rules, which step happens first?

Answer: C

Explanation:
Order of Execution Rules:
Step 1: Original record is loaded from the database.
Step 2: Field-level validations are performed, including maximum field lengths.
Step 3: Old values are overwritten with new record values.
Step 4: JavaScript validation runs in the browser.

NEW QUESTION # 123
While working in a sandbox, an Apex test fails when run in the Test Runner. However, executing the Apex logic in the Execute Anonymous window succeeds with no exceptions or errors. Why did the method fail in the sandbox test framework but succeed in the Developer Console?

Answer: C

Explanation:
The Apex test fails in the Test Runner but succeeds in the Execute Anonymous window because the test method relies on existing data in the sandbox.
Isolation of Test Data: By default, Apex tests do not have access to pre-existing data in the organization. Tests are executed in an isolated context to ensure they are not dependent on external data, promoting reliability and repeatability.
"Apex test methods don't have access to pre-existing data in the organization. The test methods have access to all data that they create and to changes made by other test methods (unless the @IsTest(Isolated=true) annotation is used)."
- Apex Developer Guide: Isolation of Test Data from Organization Data in Unit Tests Execute Anonymous Window: When code is run in the Execute Anonymous window, it executes in the current user's context and has access to all organization data, including existing records.
"All Apex code runs in system mode. The only exception is anonymous blocks, such as code executed using the Execute Anonymous window or the SOAP API."
- Apex Developer Guide: Enforcing Object and Field Permissions
Solution: To fix the failing test, the developer should create the necessary test data within the test method or use the @IsTest(SeeAllData=true) annotation if access to existing data is absolutely necessary (though this is generally discouraged).
"If you specify @IsTest(SeeAllData=true), the test method has access to all data in the organization, but the test can be slower and less reliable because it might depend on data that changes."
- Apex Developer Guide: Using the SeeAllData Annotation
Why Other Options Are Incorrect:
Option A: While calling an @future method requires special handling in tests, it would not cause the method to pass in Execute Anonymous and fail in tests.
Option C: A syntax error would prevent the code from compiling, so it wouldn't run in either context.
Option D: Using System.runAs is only necessary when testing code that behaves differently for users with different profiles or permissions.
Conclusion: The discrepancy arises because the test method is attempting to access data that isn't available in the test context, leading to its failure in the Test Runner but success in the Execute Anonymous window.


NEW QUESTION # 124
The values 'High', 'Medium', and 'Low' are identified as common values for multiple picklists across different objects.
What is an approach a developer can take to streamline maintenance of the picklists and their values, while also restricting the values to the ones mentioned above?

Answer: B

Explanation:
* A Global Picklist Value Set allows the same set of picklist values to be shared across multiple objects, making maintenance easier and ensuring consistency.
Why not other options?
* B: Alphabetical ordering does not ensure consistent value maintenance across objects.
* C: Validation rules do not streamline picklist value maintenance.
* D: Restricting picklist values helps ensure data integrity but does not streamline maintenance across objects.
References:
* Global Picklists Documentation


NEW QUESTION # 125
An Apex method, getAccounts, that returns a List of Accounts given a searchTerm, is available for Lightning Web components to use.
What is the correct definition of a Lightning Web component property that uses the getAccounts method?

Answer: D


NEW QUESTION # 126
A developer needs to create a baseline set of data (Accounts, Contacts, Products, Assets) for an entire suite of Apex tests allowing them to test isolated requirements for various types of Salesforce cases.
Which approach can efficiently generate the required data for each unit test?

Answer: C

Explanation:
Why@TestSetup?
The@TestSetupannotation creates a baseline set of test data once per test class.
Test methods reuse this data, avoiding the need to recreate it repeatedly, which improves efficiency.
Why Not Other Options?
A: HttpCalloutMock is used for mocking callouts, not for creating test data.
C: UsingseeAllData=trueis discouraged because it relies on org data, violating test isolation principles.
D: While creating data inTest.startTest()works, it is less efficient than@TestSetupfor shared data.
