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

Question 1

A developer has written a trigger on the Account object that performs a SOQL query inside a for-loop. The developer notices that when a data load of 200 records occurs, governor limits are exceeded. What is the most efficient way to refactor this trigger?

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

Accepted Answer

Collect IDs into a Set and execute a single SOQL query outside the loop.. To avoid SOQL query limits, queries should be moved outside of loops and leverage collections (lists or sets) to retrieve all required data in a single query.

Answer

Use a static variable to cache the query results inside the loop.

Answer

Move the query into a helper method that is called recursively for each record.

Answer

Wrap the query in a try-catch block to handle governor limit exceptions.

Question 2

A developer creates an Apex trigger that updates related Contact records whenever an Account record is updated. The trigger performs a DML operation on the Contacts. During testing, updating an Account causes the trigger to fire infinitely and throw a System.LimitException: Maximum trigger depth exceeded. Which design pattern should the developer implement to prevent this recursion?

Accepted Answer

Use a static boolean flag in a helper class to ensure the trigger block executes only once per transaction.. Using a static boolean flag in a helper class is the standard Salesforce pattern to prevent recursive trigger execution by tracking whether the trigger logic has already run in the current transaction.

Answer

Use a Database.setSavepoint() before the DML operation to rollback if recursion occurs.

Answer

Convert the trigger logic into a Queueable Apex job to defer execution to a separate transaction.

Answer

Check Trigger.isExecuting to determine if the trigger is running in a recursive context.

Question 3

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

Accepted Answer

Validation rules are evaluated after all before triggers have completed execution.. Validation rules execute after the 'before' triggers have completed and modified the records, ensuring that the validated state reflects any programmatic field updates.

Answer

Validation rules execute only after after triggers complete successfully.

Answer

Validation rules are evaluated concurrently with before triggers.

Answer

Validation rules are evaluated before any before triggers execute.

Question 4

A developer needs to process 500,000 records daily and update a custom field based on complex business logic. Which asynchronous Apex feature is specifically designed to handle large batch data processing with flexible scope sizes and built-in transaction monitoring?

Accepted Answer

Batch Apex. Batch Apex is designed for processing large numbers of records (millions) by breaking them down into manageable batches and running them asynchronously.

Answer

Future Methods

Answer

Queueable Apex

Answer

Schedulable Apex

Question 5

A developer has a requirement to pass a complex SObject list containing parent and child records into an asynchronous method for further processing. Which asynchronous feature supports passing non-primitive data types such as Lists of SObjects?

Accepted Answer

Queueable Apex. Queueable Apex supports the execution of jobs asynchronously and allows passing non-primitive data types such as lists of SObjects through class member variables.

Answer

Email Services

Future Methods

Question 6

A developer needs to ensure that a specific Apex method runs asynchronously because it makes a callout to an external REST API from a standard user interface controller. Which annotation must be added to the method?

Accepted Answer

@future(callout=true). The @future(callout=true) annotation allows an Apex method to run asynchronously and enables it to perform HTTP callouts.

Answer

@ReadOnly

Answer

@InvocableMethod

Answer

@AuraEnabled(callout=true)

Question 7

When evaluating whether to use Flow Builder or an Apex trigger for record automation, which scenario best justifies choosing an Apex trigger over a Record-Triggered Flow?

Accepted Answer

Executing custom callouts and complex recursive logic across multiple related parent and child objects in bulk.. Apex triggers are recommended over flows when handling complex multi-object transactional logic, callouts, or heavy bulk operations where performance and fine-grained control are paramount.

Answer

Sending a simple email alert when a Case status changes.

Answer

Displaying a custom validation error message on a field.

Answer

Updating a field on the same record before it is saved.

Question 8

Which trigger context variable should a developer use to access the map of old record versions prior to the update operation?

Accepted Answer

Trigger.oldMap. Trigger.oldMap provides a map of IDs to the old versions of the SObject records for update and delete triggers.

Answer

Trigger.old

Answer

Trigger.newMap

Answer

Trigger.new

Question 9

When should a developer choose a Record-Triggered Flow over an Apex trigger for automating record updates before save?

Accepted Answer

When updating fields on the same record being saved for better performance and maintainability.. Before-save record-triggered flows execute faster than Apex before-triggers and are fully declarative, making them the preferred choice for same-record field updates.

Answer

When the automation requires complex external web service callouts.

Answer

When handling recursive trigger execution across multiple custom objects.

Answer

When performing complex DML operations on up to five related child objects.

Question 10

A developer is writing an Apex trigger and needs to ensure proper bulkification. Which TWO practices should the developer follow to avoid governor limits? (Choose two.)

Accepted Answer

Perform SOQL queries and DML operations outside of loops.. Bulkification requires processing data in collections (lists/sets) and placing all DML and SOQL operations outside of loops.

Answer

Use single record DML statements inside a standard for-loop.

Answer

Hardcode record IDs to query specific test records.

Answer

Annotate the trigger with @future to ensure asynchronous bulk processing.

Question 11

Which TWO statements are true regarding Queueable Apex compared to future methods? (Choose two.)

Accepted Answer

Queueable Apex returns an AsyncApexJob ID that can be used to monitor job progress.. Queueable Apex offers job IDs for tracking and supports complex data types, unlike future methods.

Answer

Future methods support chaining multiple jobs sequentially.

Answer

Queueable Apex cannot perform HTTP callouts.

Answer

Queueable Apex methods must be annotated with @future.

Question 12

When should a developer choose to implement Schedulable Apex? (Choose two.)

Accepted Answer

To execute long-running batch processing or maintenance tasks periodically.. Schedulable Apex is used to run Apex classes at scheduled times or intervals, such as nightly batch jobs or periodic maintenance tasks.

Answer

To respond instantly to record inserts or updates.

Answer

To handle immediate real-time user interface validation.

Answer

To perform synchronous HTTP callouts directly from a Lightning Component button.

Question 13

A developer needs to execute long-running computations that require complex chaining and the ability to pass non-primitive data types to the job. Which asynchronous feature should the developer implement?

Accepted Answer

Queueable Apex. Queueable Apex supports the Database.AllowsCallouts interface, allows chaining of jobs, and accepts member variables of non-primitive types such as custom objects.

Answer

Schedulable Apex

Answer

Future methods

Answer

Batch Apex

Question 14

An Apex trigger needs to update fields on the same record that is currently being inserted in a Before Insert trigger context. How should the developer implement this update?

Accepted Answer

Assign values directly to the fields on the records in Trigger.new.. In a before insert trigger, records are already in memory and have not yet been saved to the database. Developers can modify fields directly on the Trigger.new records without calling an explicit DML operation.

Answer

Use an immediate DML statement update Trigger.new; inside the trigger.

Answer

Instantiate a separate list of the same records and call database.insert().

Answer

Utilize an after insert trigger to perform an update DML operation.

Question 15

A developer has written a Batch Apex class to process millions of records. During execution, some transactions fail due to temporary external web service timeouts. What is the standard behavior of Batch Apex when an unhandled exception occurs in a batch execution?

Accepted Answer

The specific batch scope fails, but the job continues processing subsequent scopes.. By default, if an unhandled exception occurs in the execute method of a batch class, that specific batch of records fails, and the batch job continues processing the remaining batches, logging the failure.

Answer

The entire job pauses indefinitely until an administrator manually resumes it via Setup.

Answer

The batch framework automatically retries the failed scope up to five times before moving on.

Answer

The entire batch job immediately aborts and rolls back all previously processed scopes.
