Salesforce : PDII Questions & Answers

A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and SP3 (created in order), before the final execution of the process. During the final execution process, the developer has a routine to roll back to SP1 for a given condition. Once the condition is fixed, the code then calls a roll back to SP3 to continue with final execution. However, when the roll back to SP3 is called, a runtime error occurs. Why does the developer receive a runtime error?

• A. The developer should have called SP2 before calling SP3.
• B. The developer has too many DML statements between the savepoints.
• C. The developer used too many savepoints in one trigger session.
• D. SP3 became invalid when SP1 was rolled back.

A developer created a JavaScript library that simplifies the development of repetitive tasks and features and uploaded the library as a static resource called jsUtils in Salesforce.

• A. import {jsUtilities} from '@salesforce/resourceUrl/jsUtils';
• B. <lightning=require scripts="{$Resource.jsUtils}"/>
• C. const jsUtility = $A.get('$Resource.jsUtils');
• D. import jsUtilities from '@salesforce/resourceUrl/jsUtils';

A company wants to run different logic based on an Opportunity's record type. Which code segment handles this request and follows best practices?

• A. Java
  List<RecordType> recTypes = [SELECT Id, Name FROM RecordType WHERE SobjectType =
  'Opportunity' AND IsActive = True];
  Map<String, Id> recTypeMap = new Map<String, Id>();
  for (RecordType rt : recTypes) {
  recTypeMap.put(rt.Name, rt.Id);
  }
  for (Opportunity o : Trigger.new) {
  if (recTypeMap.get('New') != null && o.RecordTypeId == recTypeMap.get('New')) {
  // do some logic Record Type 1
  }
  else if (recTypeMap.get('Renewal') != null && o.RecordTypeId == recTypeMap.get('Renewal')) {
  // do some logic for Record Type 2
  }
  }
• B. Java
  Id newRecordTypeId = Schema.SObjectType.Opportunity.getRecordTypeInfosByName().get('New').
  getRecordTypeId();
  Id renewalRecordTypeId = Schema.SObjectType.Opportunity.getRecordTypeInfosByName().get ('Renewal').getRecordTypeId(); for (Opportunity o : Trigger.new) { if (o.RecordTypeId == newRecordTypeId) {
  // do some logic Record Type 1
  }
  else if (o.RecordTypeId == renewalRecordTypeId) {
  // do some logic for Record Type 2
  }
  }
• C. Java
  List<RecordType> recTypes = [SELECT Id, Name FROM RecordType WHERE SobjectType =
  'Opportunity' AND IsActive = True];
  Map<String, Id> recTypeMap = new Map<String, Id>();
  for (RecordType rt : recTypes) {
  recTypeMap.put(rt.Name, rt.Id);
  }
  for (Opportunity o : Trigger.new) {
  if(o.RecordTypeId == recTypeMap.get('New')) {
  // do some logic Record Type 1
  } else if (o.RecordTypeId == recTypeMap.get('Renewal')) {
  // do some logic for Record Type 2
  }
  }
• D. Java
  for (Opportunity o : Trigger.new) {
  if (o.RecordType.Name == 'New') {
  // do some logic Record Type 1
  }
  else if (o.RecordType.Name == 'Renewal') {
  // do some logic for Record Type 2
  }
  }
