SALESFORCE-PD1 Practice Test 5 — 10 Questions

Question 1

Which THREE collections are available in Apex? (Choose three.)

Accepted Answer

Set. Apex provides three built-in collection types: List, Set, and Map.

Answer

Queue

Answer

Table

Question 2

A developer has written a test method that requires a large volume of test data to be set up. To avoid writing duplicate data setup code across multiple test methods in the same class, which annotation should the developer use?

Accepted Answer

@TestSetup. The @TestVisible annotation is incorrect for data setup. The @TestSetup annotation executes once per test class and creates data for all test methods in that class.

Answer

@isTest(SeeAllData=true)

Answer

@TestVisible

Answer

@Future

Question 3

A developer wants to test an asynchronous future method. Where must the developer place the asynchronous code execution so that it runs synchronously and within the test context?

Accepted Answer

Between Test.startTest() and Test.stopTest(). Test.startTest() and Test.stopTest() bracket the code block where asynchronous processes like future methods, batch jobs, and queueables are forced to execute synchronously.

Answer

Inside a System.runAs() block

Answer

Within a try-catch block

Answer

Inside a Database.executeBatch block

Question 4

Which THREE operations can cause an automatic roll back of an entire Apex transaction? Choose 3 options.

Accepted Answer

Exceeding a governor limit such as SOQL query count.. Unhandled exceptions, unhandled DML errors with allOrNone=true, and governor limit violations roll back the transaction.

Answer

Catching a DmlException inside a try-catch block.

Answer

Executing Database.insert(records, false) with partial failure.

Question 5

Which TWO best practices should a developer follow when writing bulkified Apex triggers? (Choose TWO.)

Accepted Answer

Perform DML statements and SOQL queries outside of loops by utilizing collections.. Bulkified triggers must operate on collections (Trigger.new) and avoid SOQL/DML inside loops.

Answer

Hardcode record IDs in trigger logic to route specific test accounts.

Answer

Use synchronous callouts directly inside before insert triggers.

Answer

Place SOQL queries inside loops to ensure every record gets fresh data.

Question 6

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 7

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 8

Which TWO statements are true regarding the Salesforce security model and Apex execution context? Choose 2 answers.

Accepted Answer

Apex code runs in system mode by default, ignoring object and field-level permissions.. Apex runs in system mode by default (ignoring FLS and CRUD), and sharing rules are only enforced if 'with sharing' is declared.

Answer

System mode ignores record-level sharing rules and user permissions entirely.

Answer

Apex code automatically enforces sharing rules unless declared 'without sharing'.

Answer

Profile permissions always override Apex system mode execution.

Question 9

Where can a developer view the generated debug logs for an Apex execution in the Salesforce UI?

Accepted Answer

Setup > Monitor > Debug Logs. Debug logs are accessible via the Setup menu under 'Debug Logs' or within the Developer Console.

Answer

Setup > Deployment > Logs

Answer

Setup > Security > Audit Trail

Answer

Setup > Custom Code > Apex Settings

Question 10

A developer needs to convert a string variable containing an alphanumeric Salesforce ID into an ID primitive data type. Which approach is valid in Apex?

Accepted Answer

Id myId = myString;. Passing a string to the Id constructor (Id myId = (Id)myString; or Id myId = myString;) automatically casts or converts valid string IDs to the Id type.

Answer

Id myId = String.toId(myString);

Answer

Id myId = Id.valueOf(myString);

Answer

Id myId = Integer.valueOf(myString);
