SALESFORCE-PD1 Process Automation And Logic Practice Test 3 — 15 Questions

Question 1

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 2

A batch Apex class processes 50,000 records. During the execute method, a custom governor limit is approached. Which method can the developer call to check the remaining CPU time dynamically?

Accepted Answer

Limits.getCpuTime(). Limits.getLimitCpuTime() and Limits.getCpuTime() allow developers to monitor resource usage dynamically.

Answer

System.getCPU()

Answer

AsyncApexJob.getCpuTime()

Answer

BatchContext.getCpuTime()

Question 3

What is the maximum number of batch Apex jobs that can be queued or active concurrently in the Apex flex queue?

Accepted Answer

100. The Apex flex queue holds up to 100 batch jobs waiting to be processed.

Answer

50

Answer

5

Answer

500

Question 4

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 5

An enterprise application requires real-time integration where outgoing callouts must be triggered from an Apex trigger. What architectural pattern must the developer use?

Accepted Answer

Future method annotated with @future(callout=true) invoked from an after trigger.. Triggers cannot make direct synchronous callouts, so they must invoke an asynchronous mechanism like a future method with callout=true.

Answer

Batch Apex execute method without queueing.

Answer

Direct synchronous HTTP callout inside the before insert trigger.

Answer

Validation rule containing an endpoint URL.

Question 6

A developer has a trigger that updates related child records. To prevent recursive trigger execution when updates ripple through child triggers, what is a standard best practice design pattern?

Accepted Answer

Using a static boolean flag in a utility class to track execution state.. Using a static boolean flag in a helper class is the classic pattern to prevent recursive trigger execution in Salesforce.

Answer

Using Flow Builder instead of Apex triggers for all child records.

Answer

Disabling all triggers via Custom Settings permanently.

Answer

Wrapping every DML statement in a try-catch block.

Question 7

Which feature allows administrators to invoke an Apex method from a Flow?

Accepted Answer

@InvocableMethod. The @InvocableMethod annotation exposes Apex methods to flows and process builder.

Answer

@RemoteAction

Answer

@future

Answer

@AuraEnabled

Question 8

A developer needs to write a test class for a Batch Apex job. Which method must be called to verify that the batch job executes correctly?

Accepted Answer

Database.executeBatch() enclosed by Test.startTest() and Test.stopTest(). Database.executeBatch inside Test.startTest() and Test.stopTest() executes the batch job in test context.

Answer

Test.runBatch()

Answer

Test.enqueueJob()

Answer

System.runAs()

Question 9

A developer needs to ensure that a custom logging operation runs asynchronously and can be monitored using job IDs. Which interface is best suited?

Accepted Answer

Queueable. Queueable Apex provides job IDs upon enqueueing, allowing for tracking and monitoring.

Answer

Schedulable

Answer

Database.AllowsCallouts

Answer

Database.Batchable

Question 10

What is a key advantage of using Queueable Apex over future methods?

Accepted Answer

Queueable Apex allows passing sObjects and custom Apex types as member variables.. Queueable Apex supports non-primitive data types and job chaining.

Answer

Queueable Apex executes synchronously on the user thread.

Answer

Queueable Apex has no governor limits.

Answer

Queueable Apex cannot make callouts.

Question 11

Which context variable should be used in an after update trigger to compare old field values with new field values?

Accepted Answer

Trigger.newMap and Trigger.oldMap. Trigger.oldMap combined with Trigger.newMap allows comparing old and new values by record ID.

Answer

Trigger.operationType

Answer

Trigger.size

Question 12

In the Salesforce order of execution, when are assignment rules evaluated relative to Apex triggers?

Accepted Answer

After Before Triggers and before After Triggers.. Assignment rules run after the insert or update before triggers and standard validations, but before after triggers.

Answer

Concurrently with workflow rules.

Answer

After all triggers have completely finished.

Answer

Before any triggers execute.

Question 13

A developer writes a Queueable Apex job that queries 50,000 records, performs calculations, and updates them. During testing, the job hits a heap size limit. What is the standard asynchronous heap size limit in Apex?

Accepted Answer

12 MB. The asynchronous transaction heap size limit is 12 MB, compared to 6 MB for synchronous transactions.

Answer

50 MB

Answer

36 MB

Answer

6 MB

Question 14

A developer needs to abort a scheduled Apex job programmatically from within a test class or maintenance script. Which method should be used?

Accepted Answer

System.abortJob(). System.abortJob(jobId) cancels a scheduled or flex-queued asynchronous job.

Answer

System.cancelJob()

Answer

apexJob.terminate()

Answer

Database.stopBatch()

Question 15

Which TWO actions can be performed inside a before insert Apex trigger without causing a runtime exception? (Choose two.)

Accepted Answer

Modifying field values on records in Trigger.new directly without a DML statement.. Before insert triggers allow modifying field values on Trigger.new directly and adding errors via addError(). DML statements and sending emails require after context or incur exceptions/limit issues.

Answer

Accessing Trigger.oldMap to compare previous values.

Answer

Performing an immediate synchronous HTTP callout to an external REST service.

Answer

Executing an explicit update DML statement on records in Trigger.new.
