SALESFORCE-PD1 Process Automation And Logic Practice Test 2 — 15 Questions

Question 1

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

Question 2

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 3

A developer needs to pass a custom SObject record with related child lists into an asynchronous execution context. Which asynchronous Apex feature supports passing non-primitive types such as custom Apex objects or sObject collections?

Accepted Answer

Queueable Apex. Queueable Apex supports member variables of non-primitive types, including sObjects and custom classes.

Answer

Scheduled Apex

Answer

Future methods

Answer

Trigger asynchronous execution blocks

Question 4

A developer wrote a batch job that encounters unhandled exceptions on specific records. To ensure that processing of other records continues despite errors in a chunk, what parameter should be configured in the start method or execution?

Accepted Answer

Database.upsert with allOrNone set to false. Using Database.executeBatch with the default scope or handling exceptions within the execute method using try/catch ensures successful records are committed while failed ones can be logged.

Answer

Database.allowsCallouts

Answer

System.abortJob()

Answer

Database.rollback()

Question 5

Which best practice should be followed when writing Apex triggers to ensure bulkification?

Accepted Answer

Design triggers to process collections of records in bulk using collections and bulk SOQL queries.. Triggers must be written to handle collections of records (Trigger.new / Trigger.old) rather than single records.

Answer

Always query inside a for loop for every record.

Answer

Use future methods for every trigger execution.

Answer

Hardcode record IDs in trigger logic for performance.

Question 6

Which tool provides a declarative alternative to Apex triggers for creating records when another record is created?

Accepted Answer

Record-Triggered Flow. Record-triggered flows in Flow Builder allow declarative creation of related records.

Answer

Validation Rules

Answer

Assignment Rules

Answer

Approval Processes

Question 7

A developer needs to execute a batch job every Sunday at midnight. Which interface must the scheduling class implement?

Accepted Answer

Schedulable. Scheduled Apex requires implementing the Schedulable interface.

Answer

Queueable

Answer

Database.Batchable<SObject>

Answer

Database.AllowsCallouts

Question 8

An Apex trigger needs to prevent deletion of Account records that have related active Contacts. When should this check occur?

Accepted Answer

Before Delete. Before delete triggers are used to validate and prevent the deletion of records based on related criteria.

Answer

After Insert

Answer

After Update

Answer

Before Insert

Question 9

A Queueable Apex job implements Database.AllowsCallouts and chains another Queueable job. What is the maximum number of jobs that can be chained in a single transaction chain?

Accepted Answer

5. Queueable jobs can be chained, but only one child job can be spawned per execution, up to a maximum depth limit of 5 in a synchronous transaction chain (or more depending on async chains, but standard chaining depth is limited).

Answer

Unlimited

Answer

1

Answer

50

Question 10

What is the primary benefit of using Flow Builder over Apex triggers when implementing simple field validations?

Accepted Answer

Flows can be managed and updated declaratively without code deployment.. Flow Builder allows administrators and developers to build validations declaratively without writing and maintaining code.

Answer

Flows bypass all system validation rules automatically.

Answer

Flows do not count against governor limits.

Answer

Flows execute faster than compiled Apex triggers.

Question 11

Which method is used in an Apex trigger to display a custom error message on a specific record during a before insert event?

Accepted Answer

addError(). The addError() method on an sObject instance prevents the DML operation and displays an error message.

Answer

throw new TriggerException()

Answer

ApexPages.addMessage()

Answer

rejectRecord()

Question 12

A developer encounters a 'System.AsyncException: Maximum queueable jobs added to the queue' error. What caused this exception?

Accepted Answer

Exceeding the maximum number of 50 queued jobs in a single transaction.. Exceeding the limit of 50 queued jobs added to the flex queue in a single transaction triggers this AsyncException.

Answer

Running more than 500 batch jobs simultaneously.

Answer

Exceeding the daily asynchronous Apex limit of 250,000.

Answer

Making more than 100 callouts in a future method.

Question 13

A developer needs to execute a lightweight background task that does not require complex chaining or monitoring. Which asynchronous feature is easiest to implement for a single method call?

Accepted Answer

Future Method. Future methods are the simplest way to run asynchronous code when no complex state or chaining is needed.

Answer

Batch Apex

Answer

Schedulable Apex

Answer

Custom Invocable Action

Question 14

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 15

A developer implements a Queueable class that makes callouts and needs to test it using Test.startTest() and Test.stopTest(). When does the asynchronous queueable job execute during a unit test?

Accepted Answer

When Test.stopTest() is executed.. Asynchronous code executed inside Test.startTest() and Test.stopTest() runs synchronously when Test.stopTest() is called.

Answer

At the end of the test method automatically without stopTest.

Answer

Immediately when enqueued.

Answer

Only when explicitly mocked via HttpCalloutMock.
