NEW QUESTION # 74
Which statement should be used to allow some of the records in a list of records to be inserted if others fail to be inserted?
- A. Insert (records, false)
- B. insert records
- C. Database.insert(records, true)
- D. Database.insert (records, false)
Answer: D
Explanation:
To allow partial success when inserting a list of records, the developer should use the Database class methods with the allOrNone parameter set to false.
Option B: Database.insert(records, false)
Correct Answer.
The Database.insert() method allows for partial processing.
By setting the second parameter (allOrNone) to false, the operation will attempt to insert all records.
If some records fail, the successful ones will be committed, and the errors can be examined from the result.
Usage:
Database.SaveResult[] results = Database.insert(records, false);
for (Database.SaveResult sr : results) {
if (sr.isSuccess()) {
// Record inserted successfully
} else {
// Handle errors
for (Database.Error err : sr.getErrors()) {
System.debug(err.getMessage());
}
}
}
The insert statement does not allow partial success; it operates with allOrNone set to true by default.
If any record fails, the entire operation is rolled back.
Option C: Insert(records, false)
Incorrect Syntax.
The insert keyword cannot take parameters.
The correct method with parameters is Database.insert().
Option D: Database.insert(records, true)
Incorrect.
Setting allOrNone to true (default behavior) means that if any record fails, the entire transaction is rolled back.
Conclusion:
To allow partial inserts when some records fail, use Database.insert(records, false), which is Option B.
Reference:
Database Methods for DML
Incorrect Options:
Option A: insert records
Incorrect.

When importing an Apex method into a Lightning Web Component (LWC), the correct syntax is:
import methodName from '@salesforce/apex/ClassName.methodName';
Option D: import updateAccounts from '@salesforce/apex/AccountController.updateaccounts'; Correct Syntax.
import updateAccounts:
Specifies the JavaScript function name to reference in the LWC.
from '@salesforce/apex/AccountController.updateaccounts';:
Indicates that we are importing from an Apex class named AccountController, and the method is updateaccounts.
Case Sensitivity:
The class and method names are case-sensitive and should match the Apex code.
Reference:
Importing Apex Methods
Apex Methods in Lightning Web Components
Incorrect Options:
Option A: import updateaccounts from '@salesforce/apeax/AccountController'; Incorrect Module Path:
Misspelling in the module path (apeax instead of apex).
Missing Method Reference:
Does not specify the method to import.
Option B: import updateaccounts from 'AccountController';
Incorrect Module Path:
Missing the @salesforce/apex/ prefix.
Reference to Class Only:
Does not specify the method to import.
Option C: import updateaccounts from 'c/AccountController.updateaccounts'; Incorrect Namespace:
'c/' is used for importing custom JavaScript modules, not Apex methods.
Incorrect Module Path:
Should use @salesforce/apex/ for Apex methods.
Conclusion:
The correct code statement is Option D, which follows the proper syntax for importing an Apex method into an LWC.

NEW QUESTION # 80
Universal Containers (UC) processes orders in Salesforce in a custom object, Order__c. They also allow sales reps to upload CSV files with thousands of orders at a time.
A developer is tasked with integrating orders placed in Salesforce with UC's enterprise resource planning (ERP) system.
After the status for an Order__c is first set to 'Placed', the order information must be sent to a REST endpoint in the ERP system that can process one order at a time.
What should the developer implement to accomplish this?
- A. Flow with a callout from an invocable method
- B. Callout from a Queueable class called from a trigger
- C. Callout from a Batchable class called from a scheduled job
- D. Callout from an @future method called from a trigger
Answer: B
Explanation:
* Why Queueable Class?
* Queueable Apex supports callouts and allows chaining to process one record at a time efficiently.
* The trigger detects when theOrder__cstatus changes to "Placed" and enqueues the Queueable class to perform the callout.
* Why Not Other Options?
* B. Batchable class: Batch jobs are ideal for bulk processing but not suited for single REST callouts.
* C. Flow with invocable method: Flows are less efficient and limited in handling callouts for large- scale operations.
* D. @future method: While it supports asynchronous callouts, it does not allow chaining, making Queueable more suitable.
