Salesforce Platform Developer II 認定 PDII 試験問題 (Q123-Q128):

質問 # 123
A company has an Apex process that makes multiple extensive database operations and web service callouts.
The database processes and web services can take a long time to run and must be run sequentially. How should the developer write this Apex code without running into governor limits and system limitations?123

A. Use Queueable Apex to chain the jobs to run sequentially.
B. Use multip9le @future methods for each process and callout.
C. Use Apex Scheduler to schedul4e each process.56
D. Use Limits class to stop entire pr7ocess once governor limits are reached.8

正解：A

解説：
This requirement specifies two critical constraints: the operations take a long time (likely exceeding synchronous CPU and timeout limits) and they must be performed sequentially.
Queueable Apex (Option D) is the optimal solution because it supports job chaining. Chaining allows one Queueable job to enqueue another Queueable job from its execute() method. This effectively creates a sequence where Job B only starts after Job A has successfully finished. Each job in the chain starts with a fresh set of governor limits, which is essential for "extensive database operations" and long-running callouts.
Option C (@future) is unsuitable because future methods cannot be chained; you cannot call one future method from another. Furthermore, the order in which multiple future methods execute is not guaranteed by the platform, violating the "sequential" requirement. Option A (Apex Scheduler) is intended for delayed or recurring tasks and is not designed for managing immediate sequential dependencies. Option B is a defensive coding practice but does not solve the underlying need to complete the work. Queueable Apex provides the programmatic control needed to manage complex, multi-step asynchronous workflows safely.

質問 # 124
Line 1 public class AttributeTypes Line 2 { Line 3 private final String[] arrayItems; Line 4 Line 5 @AuraEnabled Line 6 public List<String> getStringArray() { Line 7 Strings+ arrayItems = new String*+, 'red', 'green', 'blue' -; Line 8 return arrayItems; Line 9 } Line 10 } Consider the Apex controller above that is called from a Lightning Aura Component. What is wrong with it?

A. Line 8: method must first serialize the list to JSON before returning
B. Lines 1 and 6: class and method must be global
C. Line 1: class must be global
D. Line 6: method must be static

正解：D

質問 # 125
How should a developer assert that a trigger with an asynchronous process has successfully run?

A. Create at test data in the test class, use System.runAs() to invoke the trigger, then perform assertions.
B. Create all test data, use @future In the test class, then perform assertions.
C. Insert records into Salesforce, use seeAllData-true, then perform assertions.
D. Create all test data in the test class, invoke Test.startTest() and Test.stopTest() and then perform assertions,

正解：D

質問 # 126
When the sales team views an individual customer record, they need to see recent interactions for the customer. These interactions can be sales orders, phone calls, or Cases. The date range for recent interactions will be different for every customer record type.
How can this be accomplished?

A. Use a Lightning component to query and display interactions based on record type that is passed in using a design:attribute from the Lightning page.
B. Use batch Apex to query for the most recent interactions when the customer view screen is loaded.
C. Use Lightning Flow to read the customer's record type, and then do a dynamic query for recent interactions and display on the View page.
D. Use a dynamic form on the customer record page to display recent interactions.

正解：A

解説：
A Lightning component can dynamically query and display interactions based on the customer's record type.
The component can receive the record type as a parameter and adjust the query accordingly, providing the required functionality without batch processing or additional configurations.References: Lightning Web Components Developer Guide - Communicating with Events

質問 # 127
A company has a custom object Sales_Help_Request__c that has a Lookup relationship to Opportunity. The Sales_Help_Request__c has a number field, Number_of_Hours__c, that represents the amount of time spent on the Sales_Help_Request__c.
A developer is tasked with creating a field, Total_Hours__c, on Opportunity that should be the sum of all of the Number_of_Hours__c values for the Sales_Help_Request__c records related to that Opportunity.
What should the developer use to implement this?

A. A trigger on Sales_Help_Request__c
B. A trigger on the Opportunity object
C. A workflow rule on the Sales_Help_Request__c object
D. A roll-up summary field on the Opportunity object

正解：B
