Salesforce Platform Developer I (PDI) 認定 PDI 試験問題 (Q110-Q115):

質問 # 110
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?

A. The original record is loaded from the database.
B. Old values are overwritten with the new record values.
C. JavaScript validation is run in the browser,
D. System validation is run for maximum field lengths.

正解：A

解説：
* 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.

質問 # 111
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 field definition.
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 object's page layout.

正解：A

解説：
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.

質問 # 112
A developer created a Lightning web component called statuscomponent to be Inserted into the Account record page.
Which two things should the developer do to make this component available?
Choose 2 answers

A. Set is Exposes to true In the statuscomponent.js-meta.xml file.
B. Add <target>lightning RecordPage</target> to the statusComp .js-meta.xml file.
C. Add <targer>lightning_Recordpage</target> to the statuscomponent. js file,
D. Add <mastertabel>Account </masterLabel> to the statusComponent. js-meta.xm1 file.

正解：A、B

解説：
To make an LWC available for use on a record page:
* Target Configuration:
* Add <target>lightning__RecordPage</target> in the component's .js-meta.xml file to specify where the component can be used.
* Expose the Component:
* Set isExposed to true in the .js-meta.xml file to make the component available for use.
Example .js-meta.xml File:<?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata">
<apiVersion>57.0</apiVersion>
<isExposed>true</isExposed>
<targets>
<target>lightning__RecordPage</target>
</targets>
</LightningComponentBundle>
* A: Incorrect placement. The <target> tag must be in the .js-meta.xml file, not the JavaScript file.
* D: The <masterLabel> tag is used for metadata labeling, not for exposing or targeting a component.
* LWC Metadata Configuration: https://developer.salesforce.com/docs/component-library/documentation

質問 # 113
A software company uses the following objects and relationships:
* Case: to handle customer support issues
* Defect__c: a custom object to represent known issues with the company's software
* Case_Defect__c: a junction object between Case and Defect__c to represent that a defect is a cause of a customer issue Case and Defect__c have Private organization-wide defaults.
What should be done to share a specific Case_Defect__c record with a user?

A. Share the Case_Defect_c record.
B. Share the parent Case record.
C. share the parent Defect__c record.
D. Share the parent Case and Defect_c records.

正解：D

解説：
Since Case and Defect__c have Private organization-wide defaults (OWD), users need explicit access to the parent records to access the child records in a master-detail or junction object relationship.
The Case_Defect__c is a junction object between Case and Defect__c.
Option C: Share the parent Case and Defect__c records.
Correct Answer.
To access a record on a junction object (Case_Defect__c), a user must have access to both parent records.
Sharing both the Case and Defect__c records with the user will grant them access to the Case_Defect__c record.
Sharing only the Defect__c record is not enough; access to the Case is also required.
Option B: Share the parent Case record.
Insufficient.
Option D: Share the Case_Defect__c record.
*Not Possible Directly.
Sharing rules cannot be applied directly to junction object records in a master-detail relationship.
Access is controlled through the parent records.
Conclusion:
To share a specific Case_Defect__c record with a user, you need to share both the parent Case and Defect__c records, which is Option C.
Reference:
Sharing Considerations for Junction Objects
Sharing Behavior
Incorrect Options:
Option A: Share the parent Defect__c record.
Insufficient.

質問 # 114
When creating unit tests in Apex, which statement is accurate?Choose 2

B. Unit tests with multiple methods result in all methods failing every time one method fails.
C. Increased test coverage requires large test classes with many lines of code in one method.
D. System Assert statements that do not Increase code coverage contribute important feedback in unit tests

正解：C、D
