Salesforce Platform Developer II 認定 PDII 試験問題 (Q13-Q18):

質問 # 13
Universal Containers is implementing a new approval process for expense reimbursements. The process requires complex logic to determine the appropriate approver based on factors such as expense amount, employee role, and project type. The solution should allow for flexibility and future changes in the approval rules.
Which approach would be the most suitable for implementing this logic?

A. Use the Salesforce Approval Process feature and define multiple approval steps with entry criteria and approval assignments.
B. Implement a custom formula field to calculate and determine the appropriate approver based on the given criteria.
C. Develop a custom Lightning component to handle the approval logic and integrate it into the expense reimbursement record page.
D. Create a custom Apex class with a method to determine the appropriate approver based on the given criteria.

正解：D

解説：
Creating a custom Apex class with methods to determine the appropriate approver is the most suitable approach when dealing with complex logic and the need for flexibility. This approach allows for centralized logic that can be easily maintained and updated as business requirements change.References: Apex Developer Guide - Apex Classes

質問 # 14
A company notices that their unit tests in a test class with many methods to create many records for prerequisite reference data are slow.
What can a developer to do address the issue?

A. Move the prerequisite reference data setup to the constructor for the test class.
B. Move the prerequisite reference data setup to a @testSetup method in the test class.
C. Move the prerequisite reference data setup to a TestDataFactory and call that from each test method.
D. Move the prerequisite reference data setup to a static method in the test class and call that from each test method.

正解：C

質問 # 15
Consider the controller code below that is called from an Aura component and returns data wrapped in a class.

The developer verified that the queries return a single record each and there is error handling in the Aura component, but the component is not getting anything back when calling the controller getSemeData.
'What is wrong?

A. The member's Kame and option of the class MyDataWrapper should be annotated with @AuraEnabled also.
B. Instances of Apex classes, such as MyDatsWrapper, cannot be returned to a Lightning component.
C. The member's Name and option should not be declared public.
D. The member's Name and option should not have getter and setter.

正解：A

質問 # 16
A user receives the generic "An internal server error has occurred" while interacting with a custom Lightning component.
What should the developer do to ensure a more meaningful message?

A. Add an onerror event handler to the tag.
B. Use platform events to process the error
C. Use an AuraHandledexception in a try-catch block.
D. Add an error-view component to the markup.

正解：C

解説：
An AuraHandledexception is a custom exception class that can be used to handle errors in Lightning components. By using an AuraHandledexception in a try-catch block, the developer can catch any exceptions that occur in the Apex controller and return a meaningful message to the component. The component can then display the message to the user using a toast or an alert. This way, the user does not see the generic "An internal server error has occurred" message, which is not helpful for debugging or troubleshooting. Reference: [Handle Server Errors in Lightning Components], [AuraHandledException Class]

質問 # 17
Refer to the following code snippet:
Java
public class LeadController {
public static List<Lead> getFetchLeadList(String searchTerm, Decimal aRevenue) { String safeTerm = '%'+searchTerm.escapeSingleQuotes()+ '%'; return [ SELECT Name, Company, AnnualRevenue FROM Lead WHERE AnnualRevenue >= :aRevenue AND Company LIKE :safeTerm LIMIT 20
];
}
}
A developer created a JavaScript function as part of a Lightning web component (LWC) that surfaces information about Leads by wire calling getFetchLeadList when certain criteria are met. Which three changes should the developer implement in the Apex class above to ensure the LWC can display data efficiently while preserving security?1

A. Use the WITH SECURITY_ENFORCED clause within the SOQL query.
B. Annotate 8the Apex method with @AuraEnabled(Cacheable=true).
C. Annotate the Apex method with @AuraEnabled.
D. Implement the with sharing keyword in the class declaration.567
E. Implement the without sharing keyword in the class declaration.

正解：A、B、D

解説：
Compreh17ensive and Detailed 11850 to 250 words of Explanation:
To make an Apex method compatible with a Lightning Web Component's @wire service and ensure it follows security best practices, three specific modifications are required:
* @AuraEnabled(Cacheable=true) (Option C): The @wire service in LWC requires the Apex method to be marked as cacheable. This enables client-side caching via the Lightning Data Service, which significantly improves UI performance by reducing redundant server calls. Note that Cacheable=true is mandatory for @wire but optional for imperative calls.
* with sharing (Option B): In Apex, classes do not enforce sharing rules by default. To ensure the user only sees Leads they have access to according to the organization-wide defaults and sharing model, the class must explicitly use the with sharing keyword.
* WITH SECURITY_ENFORCED (Option A): While with sharing handles record-level access, it does not automatically enforce field-level security (FLS) or object-level security (CRUD). Adding the WITH SECURITY_ENFORCED clause to the SOQL query ensures that if a user does not have permission to view the AnnualRevenue field, the query will throw an exception rather than exposing protected data.
Options D and E are incorrect because without sharing bypasses security, and a simple @AuraEnabled without cacheable=true is insufficient for the LWC @wire service.
