SALESFORCE-PD1 Process Automation And Logic Practice Test 9 — 15 Questions

Question 1

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?

Choose an answer to begin — your selection is scored in the full session.

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 2

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.. Trigger recursion can be prevented using static boolean flags in a helper class, utilizing trigger context maps to check if specific fields actually changed, or leveraging custom metadata/settings to disable triggers dynamically.

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 3

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 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

When using a @future method, what data type is allowed as a parameter?

Accepted Answer

String. Future methods only accept primitive data types or collections of primitive data types.

Answer

SObject

Answer

Apex Class instance

Answer

List of SObjects

Question 6

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 7

A developer needs to execute logic after a record is inserted into the database but before the database commits the transaction. Which trigger event is most appropriate?

Accepted Answer

after insert. The after insert trigger event executes after the record is saved to the database but before the final commit.

Answer

before insert

Answer

before update

Answer

after update

Question 8

Which trigger context variable should be used to check if a trigger is running in a before-insert context?

Accepted Answer

Trigger.isBefore && Trigger.isInsert. Trigger.isBefore and Trigger.isInsert are standard context variables.

Answer

Trigger.isBeforeInsert

Answer

Trigger.context == 'beforeInsert'

Answer

Trigger.beforeInsert

Question 9

A developer needs to call an external web service from an Apex trigger. Why must this be done asynchronously?

Accepted Answer

To prevent callouts from blocking the transaction. DML operations and external callouts cannot be mixed in the same transaction; callouts require asynchronous processing.

Answer

To increase governor limits for DML

Answer

Because triggers are limited to 10 callouts

Answer

To allow the trigger to run faster

Question 10

In the order of execution, when do record-triggered flows that are configured to run 'before' the record is saved execute?

Accepted Answer

After the before-save Apex triggers. Record-triggered flows configured to run before the record is saved execute after the before-save triggers.

Answer

After the after-save Apex triggers

Answer

Before the before-save Apex triggers

Answer

After the commit to the database

Question 11

What is the result of using a recursive trigger without a proper exit condition?

Accepted Answer

The trigger executes until the governor limit is hit. Recursive triggers without exit conditions hit the Apex governor limit, causing the transaction to fail.

Answer

The trigger stops after 100 iterations

Answer

The trigger is automatically disabled

Answer

Infinite loop until memory runs out

Question 12

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 13

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 14

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 15

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
