SALESFORCE-PD1 Practice Test 21 — 15 Questions

Question 1

Which THREE items are best practices when setting up test data using @TestSetup methods? (Choose three.)

Accepted Answer

Perform time-consuming operations or bulk data generation once to avoid hitting governor limits in separate test methods.. Test setup methods create shared records efficiently and roll back per method.

Answer

Hardcode specific record IDs assigned during @TestSetup into downstream test assertions.

Answer

Call external REST callouts inside the @TestSetup method to fetch live seed data.

Question 2

In an after insert trigger on the Account object, a developer attempts to modify a field on Trigger.new[0] and performs an update DML statement. What happens?

Accepted Answer

A System.SObjectException is thrown because Trigger records are read-only in after triggers.. Modifying Trigger.new records in an after trigger and running DML causes a read-only exception or recursive trigger loop.

Answer

The transaction is rolled back due to governor limits.

Answer

The trigger fires infinitely without stopping.

Answer

The record updates successfully without issues.

Question 3

When should a developer use a record-triggered flow instead of a scheduled path in a flow?

Accepted Answer

When actions need to occur instantly upon record creation.. Record-triggered flows execute immediately upon record creation or update, whereas scheduled paths run at a specific time offset.

Answer

When processing millions of historical records nightly.

Answer

When making external web service callouts synchronously.

Answer

When actions need to execute 30 days after a contract is signed.

Question 4

A developer is analyzing the Salesforce order of execution for a record update. Which TWO events occur AFTER custom validation rules are evaluated? (Choose TWO.)

Accepted Answer

Execution of Assignment Rules and Escalation Rules.. After triggers and assignment rules occur after custom validation rules in the save order of execution.

Answer

Execution of Before Triggers.

Answer

Execution of custom validation rules

Answer

Execution of initial system validation (such as required field checks).

Question 5

A developer needs to schedule an Apex class to run weekly. Which THREE elements are required to implement Schedulable Apex? (Choose THREE.)

Accepted Answer

The public class must implement the Schedulable interface.. Schedulable Apex requires implementing the Schedulable interface, defining the execute method, and scheduling via System.schedule with a Cron expression.

Answer

The class must extend the Controller class.

Answer

The class must implement Database.Batchable<SObject>.

Question 6

A developer needs to execute long-running computations that require complex chaining and the ability to pass non-primitive data types to the job. Which asynchronous feature should the developer implement?

Accepted Answer

Queueable Apex. Queueable Apex supports the Database.AllowsCallouts interface, allows chaining of jobs, and accepts member variables of non-primitive types such as custom objects.

Answer

Schedulable Apex

Answer

Future methods

Answer

Batch Apex

Question 7

An asynchronous method needs to be invoked from a standard trigger to perform callouts to an external web service. Which annotation is required for this asynchronous method?

Accepted Answer

@future(callout=true). Future methods annotated with @future(callout=true) are used to perform asynchronous callouts from triggers.

Answer

@TestSetup

Answer

@InvocableMethod

Answer

@ReadOnly

Question 8

When should a developer choose Flow Builder over an Apex Trigger for business automation?

Accepted Answer

When implementing straightforward record-triggered field updates declaratively.. Flow Builder is declarative and preferred for standard point-and-click record updates and screen interactions when complex custom code is unnecessary.

Answer

When performing complex callouts to external REST APIs.

Answer

When writing custom web service classes for external clients.

Answer

When processing millions of records nightly in batches.

Question 9

Which trigger event handles the restoration of records from the Recycle Bin?

Accepted Answer

Before Undelete and After Undelete. Undelete triggers handle records restored from the recycle bin.

Answer

Before Insert and After Insert

Answer

Before Update

Answer

Before Delete and After Delete

Question 10

Which TWO best practices should developers follow when implementing Queueable Apex chaining? (Choose two.)

Accepted Answer

Ensure that chained jobs handle governor limits and bulk data efficiently in each execution context.. Chaining queueable jobs should be conditional to avoid infinite loops and should monitor flex queue limits.

Answer

Chain multiple queueable jobs simultaneously within a single synchronous transaction without limits.

Answer

Use future methods inside queueable execute methods instead of chaining queueable jobs.

Answer

Hardcode all job IDs to ensure static binding between jobs.

Question 11

A developer has written a Before Insert trigger on the Contact object that needs to validate user input and potentially prevent the record from saving. Which method on the Trigger context or record instance should the developer use to flag an error?

Accepted Answer

Record.addError(). To prevent a record from saving in a before trigger, the developer must use the addError() method on the sObject record instance.

Answer

ApexPages.addMessage()

Answer

Trigger.addError()

Answer

System.assert()

Question 12

A developer needs to ensure that an Apex trigger fires only during the after insert context. Which check should be placed at the beginning of the trigger body?

Accepted Answer

if (Trigger.isAfter && Trigger.isInsert). Checking Trigger.isAfter and Trigger.isInsert ensures the code runs only during the desired trigger event.

Answer

if (Trigger.size > 0)

Answer

if (Trigger.isExecuting)

Answer

if (Trigger.isBefore && Trigger.isUpdate)

Question 13

A developer needs to run a batch job that queries records and updates them. What is the default batch size if no optional batch size parameter is specified in Database.executeBatch()?

Accepted Answer

200. The default batch size for Database.executeBatch() is 200 records if not specified.

Answer

50

Answer

2000

Answer

500

Question 14

A developer needs to execute logic before a record is inserted into the Database to validate field values and prevent invalid records from saving. Which trigger event should the developer use?

Accepted Answer

before insert. Before insert triggers are used to perform validation, update field values, and prevent records from saving by using the addError() method on the records.

Answer

after update

Answer

after insert

Answer

before update

Question 15

Which context variable in an Apex trigger contains the old map of records for update operations?

Accepted Answer

Trigger.oldMap. Trigger.oldMap provides a map of ID to the old version of records during update and delete triggers.

Answer

Trigger.old

Answer

Trigger.new

Answer

Trigger.newMap
