Salesforce Platform Developer II Sample Questions (Q71-Q76):

NEW QUESTION # 71
Universal Containers (UC) has enabled the translation workbench and has translated picklist values. UC has a custom multi-select picklist field, Product__c, on the Account object that allows sales reps to specify which of UC's products an Account already has. A developer is tasked with writing an Apex method that retrieves Account records, including the Product_c field.
What should the developer do to ensure the value of Products__c is in the current user's language?

A. Call the translate method on each record in the SOQL result list.
B. Set the locale on each record in the SOQL result list.
C. Use tolabel ducts__c) in the fields list of the SOQL query.
D. Use the Locale clause in the SOQL query.

Answer: C

NEW QUESTION # 72
Which code snippet processes records in the most memory efficient manner, avoiding governor limits such as
"Apex heap size too large"?

A. Java
for(Opportunity opp: [SELECT Id, Amount from Opportunity]){
// perform operation here
}
B. Java
List<Opportunity> opportunities = [SELECT Id, Amount from Opportunity]; for(Opportunity opp: opportunities){
// perform operation here
}
C. Java
List<Opportunity> opportunities = Database.query('SELECT Id, Amount from Opportunity'); for(Opportunity opp: opportunities){
// perform operation here
}
D. Java
Map<Id, Opportunity> opportunities = new Map<Id, Opportunity>([SELECT Id, Amount from Opportunity]); for(Id oppId: opportunities.keySet()){
// perform operation here
}

Answer: A

Explanation:
When processing large data volumes in Apex, the "Heap Size" limit (6MB for synchronous, 12MB for asynchronous) is a common bottleneck. This limit tracks the amount of memory consumed by objects and variables currently in scope.
Option B utilizes the SOQL For Loop pattern. This is the most memory-efficient approach because it processes records in "chunks" of 200 at a time using internal query locators. Instead of loading the entire result set (potentially thousands of records) into a single collection in memory, the SOQL For Loop iterates through the records without ever holding the full set in the heap. This prevents the "Apex heap size too large" error when dealing with high-volume queries.
In contrast, Options A, C, and D all involve assigning the entire query result to a collection (a Map or List) before the loop begins. This immediately consumes heap space proportional to the number of records and fields retrieved. If the query returns a large number of records, these collections will quickly exceed the heap limit before the first line of the loop even executes. Therefore, for bulk data processing where memory efficiency is the priority, the inline SOQL For Loop (Option B) is the standard best practice.

NEW QUESTION # 73
Consider the below trigger intended to assign the Account to the manager of the Account's region:

Which two changes should a developer make in this trigger to adhere to best practices?
Choose 2 answers

Answer: B,D

Explanation:
The best practices for writing triggers in Salesforce include bulkifying your code to handle multiple records efficiently and reducing the number of SOQL queries, especially within loops, to avoid hitting governor limits.
* Option B is correct because moving the SOQL query outside of the for loop is essential to bulkify the trigger. Performing a query within a loop can cause a SOQL governor limit to be reached if the trigger is processing many records. The best practice is to collect all necessary data before the loop starts and then process it within the loop.
* Option C is correct as well, because using a Map to cache the results of a SOQL query by Id is another way to bulkify the code. This allows you to query all the necessary data once and then access it efficiently in memory, avoiding repeated queries.
* Option A is incorrect because adding isExecuting before the update doesn't address any best practices related to bulkification or SOQL query optimization.
* Option D is incorrect because the last line should not be removed if the developer intends to perform DML on the accountList. However, this line should be outside of the loop and is unnecessary if the trigger context is 'before insert' or 'before update', since in those contexts, changes to records in Trigger.
new are implicitly saved without the need for explicit DML.

NEW QUESTION # 74
A developer created a class that implements the Queueable Interface, as follows:
Java
public class without sharing OrderQueueableJob implements Queueable {
public void execute(QueueableContext context) {
// implementation logic
System.enqueueJob(new FollowUpJob());
}
}
As part of the deployment process, the developer is asked to create a corresponding test class. Which two actions should the developer take to successfully execute the test class?1

A. Ensure the running user of the test class has, at least, the View All permission on the Order object.
B. Enclose System.enqueueJob(new OrderQueueableJob()) within Test.startTest and Test.stopTest().
C. Implement Te3st.isRunningTest() to prevent chaining jobs during test execution.
D. Implement seeAllData=true to ensure the Queueable job is able to run in bulk mode.2

Answer: B,C

Explanation:
Testing asynchronous Apex, such as the Queueable interface, requires specific handling to ensure the job actually executes during the test run and adheres to platform limits.
First, Salesforce enforces a strict limit on chaining Queueable jobs during unit tests. Specifically, you cannot chain jobs (enqueue a job from another job) within a test. Since the OrderQueueableJob attempts to enqueue FollowUpJob, the test will throw an error. To resolve this, the developer should use Test.isRunningTest() (Option B) within the execute method to conditionally bypass the System.enqueueJob call during test runs.
Second, asynchronous jobs are queued by the system and do not run immediately. To force the execution of a Queueable job so that results can be asserted, the System.enqueueJob call must be wrapped within Test.
startTest() and Test.stopTest() (Option D). When Test.stopTest() is called, the execution pauses until all queued asynchronous jobs in that block finish running.
Option A is incorrect because seeAllData does not affect asynchronous processing modes. Option C is incorrect because the class is defined as without sharing, meaning it bypasses sharing rules regardless of the running user's permissions. By combining recursion/chaining guards and the startTest/stopTest block, the developer can reliably test the logic within the execute method.

NEW QUESTION # 75
What is the transaction limit on the number of "sendEmail" method calls?

A. 0
B. 1
C. 2
D. 3
E. There is no limit

Answer: D

Explanation:
The reserveEmailCapacity methods let you declare how many emails you want to send prior to actually sending, allowing you to handle limit errors prematurely
