SALESFORCE-PD1 Process Automation And Logic Practice Test 10 — 15 Questions

Question 1

A developer needs to schedule a class to run nightly at midnight to clean up stale audit records. Which interface must the class implement?

Accepted Answer

System.Schedulable. To use Schedulable Apex, the class must implement the Schedulable interface, which contains the execute(SchedulableContext SC) method.

Answer

Database.AllowsCallouts

Answer

Queueable

Answer

Database.Batchable<SObject>

Question 2

A developer implemented a Queueable Apex class that performs heavy processing. During testing, the developer wants to verify whether the asynchronous job has finished executing before running dependent unit test assertions. What should the developer use?

Accepted Answer

Test.startTest() and Test.stopTest() block around the enqueueJob call. Developers use Test.startTest() and Test.stopTest() in unit tests to force all asynchronous jobs enqueued within the block to execute synchronously before proceeding.

Answer

AsyncApexJob query inside a loop with Thread.sleep()

Answer

A custom countdown latch pattern using platform cache

Answer

System.assertAsyncExecution() method

Question 3

A developer is troubleshooting an Apex trigger recursion issue where an update operation triggers itself infinitely. Which THREE strategies can the developer use to safely prevent this recursion? Choose 3 options.

Accepted Answer

Utilize Custom Settings or Custom Metadata to provide a global toggle to turn off triggers dynamically.. Option B is correct because Custom Settings or Custom Metadata can store a global bypass flag that the trigger checks before executing, allowing developers to disable trigger logic dynamically without deploying code changes, which safely breaks recursive update loops. Option D is correct because comparing Trigger.oldMap and Trigger.newMap lets the trigger verify that the fields it cares about actually changed before performing DML, so an update that does not modify relevant fields will not re-fire the same logic and cause infinite recursion. Option E is correct because a static Boolean variable in a helper class persists for the duration of a single transaction, so setting it to false after the first execution prevents the trigger from running its logic again during the same transaction's recursive DML. Option A is not appropriate because Limits.getQueries() only reports the number of SOQL queries already issued and aborting near governor limits does not logically prevent recursion. Option C is not appropriate because recursion is not an exception that can be caught; wrapping DML in try-catch does not stop the trigger from re-invoking itself.

Answer

Call Limits.getQueries() at the start of every trigger to abort if limits are near.

Answer

Wrap all DML statements in a try-catch block that catches recursion exceptions.

Question 4

A developer is writing a Batch Apex class to update 50,000 records. Which method must be implemented to define the scope of records to be processed?

Accepted Answer

start. The start method in the Database.Batchable interface returns a QueryLocator or Iterable to define the records.

Answer

initialize

Answer

execute

Answer

finish

Question 5

A developer needs to chain asynchronous jobs. Which interface allows for a single job to be queued from within the execution of another?

Accepted Answer

Queueable. Queueable Apex allows for chaining jobs by calling System.enqueueJob within the execute method.

Answer

Batchable

Answer

Schedulable

Answer

Future

Question 6

A developer needs to access the old values of a record in an Apex trigger. Which collection provides this?

Accepted Answer

Trigger.old. Trigger.old contains the list of records before the update or deletion.

Answer

Trigger.oldMap

Answer

Trigger.map

Answer

Trigger.newMap

Answer

Trigger.new

Question 7

What is the primary benefit of using a Flow over an Apex trigger for simple field updates?

Accepted Answer

Declarative configuration. Flows are declarative, easier to maintain, and require no code, making them faster to deploy.

Answer

Higher governor limits

Answer

Access to private methods

Answer

Better performance

Question 8

A developer is building a solution that requires complex branching logic. When should the developer choose Apex over Flow?

Accepted Answer

When complex procedural logic is needed. Apex should be used when complex logic is required that cannot be represented in the Flow canvas, such as complex loops or high-performance algorithms.

Answer

When updating fields

Answer

When using standard objects

Answer

When sending emails

Question 9

A developer wants to schedule an Apex class to run daily. Which interface must the class implement?

Accepted Answer

Schedulable. The Schedulable interface is required for classes that need to be scheduled.

Answer

Batchable

Answer

Callable

Answer

Queueable

Question 10

When a record-triggered flow performs an action that causes a trigger to fire, which order of execution phase is this?

Accepted Answer

The trigger executes immediately in the same transaction. This is part of the re-entrant execution, where Salesforce processes the trigger as part of the flow's transaction.

Answer

The flow fails

Answer

The trigger is queued for later

Answer

The trigger is ignored

Question 11

Which governor limit is associated with the total number of SOQL queries issued in a single synchronous transaction?

Accepted Answer

100. The limit for synchronous SOQL queries is 100.

Answer

10

Answer

50

Answer

200

Question 12

Which of the following describes the behavior of a static variable in Apex?

Accepted Answer

It persists for the duration of the transaction. Static variables are scoped to the transaction and persist across the entire trigger execution.

Answer

It is stored in the database

Answer

It is reset for each trigger event

Answer

It is shared across all users

Question 13

Which tool is best for automating a process that requires UI interaction, such as a wizard screen?

Accepted Answer

Flow Builder. Flow Builder is the only declarative tool among the options that can present screen elements (wizard-style UI) to users, collecting input across multiple steps and then performing logic or DML. Screen Flows are specifically designed for guided UI interaction, making Flow Builder the correct choice for automating a process that requires a wizard screen.

Answer

Future Method

Answer

Batch Apex

Answer

Apex Trigger

Question 14

A developer needs to update a related record. If using Apex, what is the best practice to avoid hitting governor limits?

Accepted Answer

Collect records in a list and perform a single DML statement. Bulkify the code to perform operations on collections rather than individual records.

Answer

Use a future method for each update

Answer

Use a for loop to update records one by one

Answer

Perform DML inside the loop

Question 15

Which TWO of the following statements about Trigger.new and Trigger.old are accurate?

Accepted Answer

Trigger.old is available in update triggers. Trigger.new is always present on insert/update; Trigger.old is always present on update/delete.

Answer

Trigger.old is available in insert triggers

Answer

Trigger.newMap is available in before insert

Answer

Trigger.new is available in delete triggers
