A Visualforce page loads slowly due to the large amount of data it displays.
Which strategy can a developer use to improve the performance?

A Use Javascript to move data processing to the browser instead of the controller.
B Use the transient keywords for the List variables used in the custom controller.
C Use lazy loading to load the data on demand, instead of the controller's constructor.
D Use an apex:actionPoller in the page to load all of the data asynchronously.

A company's support process dictates that any time a Case is closed with a Status of 'Could not fix', an Engineering Review custom object record should be created and populated with information from the Case, the Contact, and any of the Products associated with the Case.
What is the correct way to automate this using an Apex trigger?

A An after update trigger that creates the Engineering Review record and inserts it
B A before update trigger that creates the Engineering Review record and inserts it
C An after upsert trigger that creates the Engineering Review record and inserts it
D A before upsert trigger that creates the Engineering Review record and inserts it

A developer writes the following Apex trigger so that when a Case is closed, a single Survey record is created for that Case. The issue is that multiple Survey_c records are being created per Case. trigger CaseTrigger on Case (after insert, after update){ List<Survey_c> createSurveys = new List<Survey_c>(); for (Case c : trigger.new){ if (c.IsClosed && (trigger.isInsert II trigger.isUpdate && trigger.oldMap.get(c.Id).IsClosed == false)){ createSurveys.add(new Survey_c(Case_c = c.Id)); } } insert createSurveys; }
What could be the cause of this issue?

A A user is creating the record as Closed
B A workflow rule is firing with a Create Task action
C A workflow rule is firing with a Field Update action
D A user is editing the record multiple times

What is a potential design issue with the following code?
trigger accountTrigger on Account (before update){ Boolean processOpportunity = false; List<opportunity> opptysClosedLost = new List<opportunity>() List<opportunity> IstAllOpp = [select StageName from Opportunity where accountId IN :Trigger.newMap.keySet()]; if(!IstAllOpp.isEmpty()) processOpportunity = true; while(processOpportunity)
{ for(opportunity o : IstAllOpp) if(o.StageName == 'Closed - Lost') opptysClosedLost.add(o); processOpportunity = false; if(!opptysClosedLost.isEmpty()) delete opptysClosedLost;

A SOQL could be avoided by creating a formula field for StageName in Account from the related Opportunity
B The code will result in a System.LimitException : Too many script statements error
C The code will result in a System.DmlException:Entity_is_Deleted error
D The code will result in a System.LimitException: Apex CPU time limit exceeded error

The Contact object has a custom field called "Zone." Its data type is "Text" and field length is 3.
What is the outcome after executing the following code snippet in the org?
List<Contact> contactsToBeInserted=new List<Contact>(); Contact contactInstance= new Contact(LastName='Smith',
Department='Tech', Zone_c='IAD'); contactsToBeInserted.add(contactInstance); contactInstance= new Contact
(LastName='Sm1th', Department='Tech', Zone_c='PITT'); contactsToBeInserted.add(contactInstance); Database.insert
(contactsToBeInserted,true);

A Both inserts succeed and the contact record that has the Zone value of 'PI'I'I' is set to NULL
B A partial insert succeeds and the contact record that has the Zone value 'IAD' is inserted
C Both inserts succeed and the contact record that has the Zone value of 'PITT' is truncated
D An unhandled DML exception is thrown and no contact records are inserted

Which statement is true regarding the use of user input as part of a dynamic SOQL query?

A Free text input should not be allowed, to avoid SOQL injection
B The String.format() method should be used to prevent injection
C Quotes should be escaped to protect against SOQL injection
D The string should be URL encoded by the input form to prevent errors

A developer has written the following method:
static void processList(List<sobject> input){
Which code block can be used to call the method?

D for Account acc : [SELECT Id, Name FROM Account])

C Configure a custom field as external ID

A developer encounters an error that states that the Apex heap size is exceeded.
Which technique may reduce heap size?

A Add the transient keyword to the variable definition
B Move the variable definition inside the scope of the function
C Use static variables instead of instance variables
D Use SOQL for loops instead of standard SOQL queries

A developer has a Debug method within a class, which is invoked hundreds of times.
What is the optimal functionality in the Developer Console to count the number of calls made to the method?

D The "Execution Tree" tab under the Stack Tree Panel

What is a consideration when testing batch Apex? (Choose two.)

A Test methods must execute the batch with a scope size of less than 200 records

A custom field Exec_Count_c of type Number is created on an Account object. An account record with value of "1" for a: Exec_Count_c is saved. A workflow field update is defined on the Exec_Count_c field, to increment its value every time an account record is created or updated. The following trigger is defined on the account: trigger ExecOrderTrigger on Account (before insert, before update, after insert, after update){ for (Account accountInstance: Trigger.New){ if (Trigger . isBefore){ accountInstance Exec_Count_c += 1; } System. debug
(accountInstance.Exec_Count_c); } }
