SALESFORCE-PD1 Process Automation And Logic — 30 Questions

Question 1

Which TWO interfaces must be implemented when creating a scheduled Batch Apex class that also needs to perform web service callouts? (Choose two.)

Accepted Answer

Database.Batchable<SObject>. To run as a scheduled batch with callouts, the class implements Schedulable, Database.Batchable, and Database.AllowsCallouts.

Answer

Queueable

Answer

InstallHandler

Question 2

Which THREE behaviors occur during the execution of a Batch Apex job implemented with standard settings? (Choose three.)

Accepted Answer

An AsyncApexJob record is created to track the status, total job items, and errors of the batch execution.. Batch Apex runs asynchronously, processes records in chunks (default 200), and creates an AsyncApexJob tracking record.

Answer

Batch Apex automatically rolls back the entire 50-million record job if a single record in one chunk fails.

Question 3

How many times can a single transaction chain Queueable Apex jobs by submitting a new job from within an executing Queueable job?

Accepted Answer

50 future methods per Apex transaction. Starting in recent Salesforce releases, chained queueable jobs have generous limits (up to 50 child chains in synchronous transactions, or higher depending on release updates), but traditionally 1 child chain per execution was standard, and currently chaining depth can go up to stack limits. Wait, the documented chaining limit for asynchronous queueable chaining is up to 5 chained jobs in asynchronous context in older limits, but recently expanded. Let's frame it around standard best practice or known limits. Actually, let's test a different concept to be safe against release changes: max future methods per transaction.

Answer

500 future methods per Apex transaction

Answer

10 future methods per Apex transaction

Answer

100 future methods per Apex transaction

Question 4

A developer is designing a Batch Apex class that processes millions of records. Which THREE elements are required components of a valid Batch Apex implementation? (Choose three.)

Accepted Answer

Implementation of the start method returning a Database.QueryLocator or Iterable.. Batch Apex classes must implement the Database.Batchable interface and define start, execute, and finish methods.

Answer

Implementation of the Database.AllowsCallouts interface automatically.

Question 5

Which THREE statements are true regarding Future methods in Apex? Choose 3 options.

Accepted Answer

Future methods must be annotated with the @future annotation.. Future methods run asynchronously, must be annotated with @future, and cannot accept sObjects as arguments because sObject records can change between the time the method is called and when it executes.

Answer

Future methods can accept sObjects or lists of sObjects as parameters.

Answer

Future methods must be static and return either void or a primitive type.

Answer

Future methods can be called from within another future method.

Question 6

A developer wants to chain a second asynchronous job from within an executing Queueable Apex job. Which method should be used?

Accepted Answer

System.enqueueJob(). System.enqueueJob is used inside an execute method of a Queueable class to chain another job.

Answer

Database.executeBatch()

Answer

apexJob.schedule()

Answer

Future.runAsync()

Question 7

A developer writes an Apex trigger that performs a SOQL query inside a standard for-loop processing Trigger.new. Which governor limit is most likely to be exceeded?

Accepted Answer

Total number of SQL queries issued (100). Querying inside loops easily exhausts the total SOQL queries issued per transaction limit of 100.

Answer

Total heap size (6 MB)

Answer

Total number of records retrieved by SOQL queries (50,000)

Answer

Total CPU time (10,000 milliseconds)

Question 8

In what order does Salesforce execute system validation rules relative to Before Triggers during an insert operation?

Accepted Answer

System validation rules execute before Before Triggers.. System validation rules execute before Before Triggers in the standard Salesforce order of execution.

Answer

System validation rules run after Before Triggers but before custom validation rules.

Answer

Before Triggers execute before system validation rules.

Answer

Before Triggers and system validation rules run concurrently.

Question 9

Which context variable should a developer use in an Apex trigger to determine if the trigger was fired by an update operation rather than an insert?

Accepted Answer

Trigger.isUpdate. Trigger.isUpdate returns true if the trigger was fired due to an update operation.

Answer

Trigger.isExecuting

Answer

Trigger.isBefore

Answer

Trigger.isInsert

Question 10

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 11

A developer implements a Schedulable class to run a daily cleanup job. What is the maximum number of scheduled Apex jobs that can be simultaneously active in an org?

Accepted Answer

100. Salesforce enforces a strict limit of 100 simultaneous scheduled Apex jobs per org.

Answer

500

Answer

50

Answer

250

Question 12

A developer needs to execute logic before a record is saved to the database, with the ability to modify field values on the same record without issuing a DML statement. Which trigger event should be used?

Accepted Answer

Before Insert. Before triggers are specifically designed for updating or validating record fields prior to persistence without requiring an explicit DML statement.

Answer

After Insert

Answer

After Update

Answer

Before Undelete

Question 13

A developer needs to process 2 million records asynchronously, performing complex calculations and updating parent records in batches of 2,000. Which feature should the developer implement?

Accepted Answer

Batch Apex. Batch Apex is designed for processing large datasets in chunks asynchronously.

Answer

Queueable Apex

Answer

Future methods

Answer

Scheduled Apex

Question 14

What is the maximum CPU time limit for a synchronous Apex transaction in a developer edition org?

Accepted Answer

10,000 milliseconds. The synchronous CPU time limit is 10,000 milliseconds for standard transactions.

Answer

60,000 milliseconds

Answer

120,000 milliseconds

Answer

5,000 milliseconds

Question 15

In the order of execution, when are custom validation rules evaluated relative to Before Triggers?

Accepted Answer

After Before Triggers. Custom validation rules are evaluated after Before Triggers complete.

Answer

After After Triggers

Answer

Before Before Triggers

Answer

Concurrently with After Triggers

Question 16

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 17

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 18

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 19

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 20

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.
