SALESFORCE-PD1 Practice Test 3 — 10 Questions

Question 1

When testing asynchronous Apex, how do you ensure that the scheduled job has finished before asserting results?

Accepted Answer

Use Test.stopTest(). Test.stopTest() forces any asynchronous processes, such as @future or Schedulables, to execute before the code execution continues.

Answer

Query the AsyncApexJob object

Answer

Use System.runAs()

Answer

Use Thread.sleep()

Question 2

How can a developer identify the most time-consuming SOQL query in a transaction?

Accepted Answer

By reviewing the debug log for query execution times.. By checking the 'Executed Units' or 'SOQL' section of the debug log for duration.

Answer

By inspecting the trigger size.

Answer

By checking the number of records returned.

Answer

By counting the number of lines in the code.

Question 3

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 4

Which of the following describes the behavior of Test.stopTest()?

Accepted Answer

It forces all queued asynchronous jobs to complete.. Test.stopTest() forces all asynchronous jobs queued during the test — future methods, batch jobs, and queueable jobs — to execute synchronously before the method returns. This allows the test to make assertions on the results of asynchronous processing within the same test method.

Answer

It clears all variables created in the test.

Answer

It resets the debug logs.

Answer

It stops all further execution of the test class.

Question 5

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 6

Which THREE pieces of information are displayed in the Apex Test Execution page?

Accepted Answer

Execution Status.. The page shows class name, status, and duration.

Answer

Code Coverage Percentage.

Answer

User who initiated the test.

Question 7

A developer is troubleshooting a transaction that exceeds governor limits due to SOQL queries. Which THREE techniques help prevent hitting SOQL query limits in Apex? (Choose THREE.)

Accepted Answer

Using maps and collections to store query results and perform in-memory lookups instead of querying inside loops.. Avoiding queries in loops, using aggregate queries, and caching results in maps/collections help avoid SOQL query limit issues.

Answer

Executing SOQL queries inside a for loop iterating over all child records.

Answer

Calling Database.query() for every single record processed in a trigger.

Question 8

An Apex trigger executes a query inside a for-loop to fetch related child records for every parent Account in Trigger.new. The developer notices that when a data load of 200 accounts occurs, the governor limit for total SOQL queries issued is exceeded. How should the developer refactor the code?

Accepted Answer

Collect the Account IDs in a Set and execute a single SOQL query outside the loop using the IN operator.. To avoid hitting the governor limit of 100 SOQL queries per transaction, queries must be moved outside of loops and bulkified using collections.

Answer

Annotate the trigger with @ReadOnly to increase the query limit.

Answer

Wrap the query in a try-catch block and catch the QueryException.

Answer

Use the Database.executeBatch method to process each account in a separate transaction.

Question 9

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 10

Which log level displays the most information?

Accepted Answer

FINEST.. In Salesforce debug logs, the log levels from lowest to highest verbosity are NONE, ERROR, WARN, INFO, DEBUG, FINE, FINER, and FINEST. FINEST displays the most detailed information, including internal execution details, making it the most verbose level.

Answer

WARN.

Answer

DEBUG.

Answer

INFO.
