SALESFORCE-PD1 Process Automation And Logic Practice Test 4 — 15 Questions

Question 1

Which TWO tools or features should a developer consider when choosing between Flow Builder and Apex for business logic automation? (Choose two.)

Accepted Answer

Apex is better suited for complex algorithmic logic, advanced error handling, and reusable utility classes.. Flow Builder is declarative and reduces maintenance, while Apex handles complex algorithms, batching, and high-volume triggers.

Answer

Flows cannot trigger subflows or call invocable actions.

Answer

Apex triggers execute significantly slower than record-triggered flows in all scenarios.

Answer

Flow Builder is required when processing millions of records nightly in asynchronous batches.

Question 2

Which THREE statements are true regarding asynchronous Apex governor limits and execution behavior? (Choose three.)

Accepted Answer

Asynchronous Apex jobs execute in their own separate transaction with independent governor limits.. Asynchronous jobs have higher limits (heap, CPU time), run in separate transactions, and can be monitored via AsyncApexJob.

Answer

Future methods can be chained indefinitely without any depth limitations.

Answer

Batch Apex jobs cannot make external web service callouts.

Question 3

Which THREE limitations apply when writing Future methods in Apex? (Choose three.)

Accepted Answer

Future methods cannot accept sObjects or custom non-primitive data types as parameters.. Future methods cannot accept sObjects, cannot be tracked easily with job IDs, and cannot be called from other future methods.

Answer

Future methods return an AsyncApexJob ID immediately upon invocation.

Answer

Future methods can be called synchronously from within another future method.

Question 4

Which TWO features are characteristic of Flow Builder compared to Apex triggers? (Choose two.)

Accepted Answer

Flows provide a visual canvas for building automation logic without writing code.. Flow Builder is declarative, provides visual debugging, and allows point-and-click creation.

Answer

Flows execute entirely on client-side browsers.

Answer

Flows require compilation into bytecode and deployment via metadata APIs or developer toolchains.

Answer

Flows cannot interact with custom objects or custom fields.

Question 5

Which THREE actions can cause a governor limit exception during a poorly optimized trigger execution? (Choose three.)

Accepted Answer

Exceeding the maximum synchronous heap size of 6 MB by loading massive attachments into collections.. Queries in loops, too many DML statements, and excessive heap size allocation trigger governor limit exceptions.

Answer

Invoking a future method directly from a scheduled Apex class execute method.

Answer

Accessing Trigger.old in an insert trigger.

Question 6

Which TWO triggers are executed during a record merge operation in Salesforce? (Choose two.)

Accepted Answer

Before Delete and After Delete triggers on the losing record.. Merging records deletes the loser record (firing delete triggers) and updates the winner record (firing update triggers).

Answer

Before Insert and After Insert triggers on the losing record.

Answer

Undelete triggers on both records.

Answer

Lead conversion triggers instead of merge triggers.

Question 7

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 8

A developer needs to execute lightweight asynchronous logic that is chainable and allows passing complex objects to the background job. Which asynchronous feature should the developer implement?

Accepted Answer

Queueable Apex. Queueable Apex supports complex member variables including sObjects and custom Apex types, and it can be chained. Future methods only support primitive types and collections of primitive types.

Answer

Schedulable Apex

Answer

Future methods

Answer

Batch Apex

Question 9

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 10

During the Salesforce save order of execution, when are before triggers executed relative to custom validation rules?

Accepted Answer

Before triggers execute before custom validation rules.. Before triggers execute before custom validation rules are evaluated, allowing developers to modify field values before validation checks run.

Answer

Before triggers execute after custom validation rules.

Answer

Before triggers execute after the record is committed to the database.

Answer

Before triggers execute concurrently with custom validation rules.

Question 11

An enterprise application requires nightly execution of an Apex class that processes records across multiple objects. Which interface must the Apex class implement?

Accepted Answer

Schedulable. To schedule an Apex job, the class must implement the Schedulable interface, specifically the execute(SchedulableContext sc) method.

Answer

Database.AllowsCallouts

Answer

Batchable

Question 12

A developer is implementing a Batch Apex class to process 500,000 Contact records. Which method defines the starting point and retrieves the records to be processed?

Accepted Answer

Database.QueryLocator start(Database.BatchableContext BC). The start method of a Database.Batchable class returns either a Database.QueryLocator or an Iterable that defines the records to be processed.

Answer

void execute(Database.BatchableContext BC, List<SObject> scope)

Answer

void finish(Database.BatchableContext BC)

Answer

Database.BatchableContext start(Database.BatchableContext BC)

Question 13

A developer creates a Trigger on the Account object that performs a SOQL query inside a for loop. While testing with bulk data operations, the developer encounters a governor limit exception. Which limit is most likely exceeded?

Accepted Answer

Total number of SOQL queries issued (100). Executing SOQL queries inside a loop without bulkification easily causes the total number of SOQL queries issued per transaction (100) to be exceeded.

Answer

Maximum CPU time on a Salesforce server (10,000 milliseconds)

Answer

Total heap size allocated (6 MB)

Answer

Total number of DML statements issued (150)

Question 14

A developer has a requirement to update child Case records whenever a parent Account's status changes. The logic requires complex looping, exception handling, and handling up to 10,000 related records. Which tool should the developer choose according to Salesforce best practices?

Accepted Answer

Apex Trigger. Apex Triggers combined with Batch Apex or bulkified code are ideal for complex business logic involving high-volume child record updates that exceed declarative flow limits.

Answer

Workflow Rule

Answer

Record-Triggered Flow

Answer

Process Builder

Question 15

A developer needs to invoke an asynchronous method from a standard synchronous Apex trigger. The asynchronous method must be annotated with which keyword?

Accepted Answer

@future. Methods intended to run asynchronously outside the current request must be annotated with @future.

Answer

@AuraEnabled

Answer

@InvocableMethod

Answer

@testVisible
