SALESFORCE-PD1 Practice Test 2 — 30 Questions

Question 1

Which THREE design patterns or tools help ensure secure coding practices regarding CRUD and FLS in Apex? Choose 3 options.

Accepted Answer

Using Security.stripInaccessible() before upserting data.. Security.stripInaccessible, WITH SECURITY_ENFORCED clause, and explicit Schema describe checks are valid methods.

Answer

Declaring every class with 'without sharing'.

Answer

Relying solely on Lightning Web Component HTML rendering tags.

Question 2

An Apex transaction performs a DML operation, followed by a callout to an external REST API, followed by another DML operation. What exception will Salesforce throw?

Accepted Answer

CalloutException. Salesforce throws a CalloutException when a DML operation has occurred before a callout in the same transaction, to prevent database locks.

Answer

AsyncException

Answer

LimitException

Answer

SystemException

Question 3

When deploying via Metadata API, what happens if a test class fails during the deployment?

Accepted Answer

The deployment fails and rolls back all changes.. The entire deployment fails by default unless specified otherwise.

Answer

Only the failing test class is ignored.

Answer

The deployment succeeds but flags a warning.

Answer

The deployment continues but prevents Apex compilation.

Question 4

Which Apex data type is best suited for storing monetary amounts with high precision?

Accepted Answer

Decimal. The Decimal data type is used for currency and precise numerical calculations in Apex.

Answer

Double

Answer

String

Answer

Integer

Question 5

What is the return type of a SOQL query that returns a single aggregate result, such as SELECT COUNT() FROM Account?

Accepted Answer

Integer. A SOQL query using COUNT() without a GROUP BY clause returns an Integer representing the row count.

Answer

AggregateResult

Answer

Decimal

Answer

List<SObject>

Question 6

An Apex trigger executes during a bulk insert of 300 records. To adhere to best practices regarding governor limits and bulkification, how should SOQL queries be written?

Accepted Answer

Query once outside the loop using a collection of IDs from Trigger.new. Queries must be written using bulkified collections, querying once outside of loops using bind variables for all records in Trigger.new.

Answer

Query inside a for-loop iterating over Trigger.new

Answer

Query each record individually using Limits.getQueries() checks

Answer

Use an asynchronous future method for every individual record

Question 7

A developer is writing a test method that performs a callout to an external REST service. Which interface must the developer implement to provide mock responses during the unit test execution?

Accepted Answer

HttpCalloutMock. HttpCalloutMock is the interface implemented to supply a mock HTTP response during test context when callouts are made.

Answer

InstallHandler

Answer

Schedulable

Answer

Database.Batchable

Question 8

Which THREE best practices should a developer follow to avoid governor limits when writing SOQL queries in Apex? Choose 3 options.

Accepted Answer

Query only the specific fields needed rather than using SELECT *.. Best practices include avoiding queries inside loops, using bind variables, and querying only necessary fields.

Answer

Execute a separate SOQL query for every child record individually.

Answer

Always use SELECT FIELDS(ALL) to ensure all data is retrieved.

Question 9

Which TWO statements about SOQL relationship queries are true? Choose 2 options.

Accepted Answer

Child-to-parent queries use dot notation (e.g., Account.Name).. Parent-to-child queries use subqueries in parentheses, and child-to-parent queries use dot notation.

Answer

SOQL supports traversing up to 10 levels of parent relationships.

Answer

Parent-to-child queries use dot notation on the parent object.

Answer

Child-to-parent queries require subqueries.

Question 10

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

Question 11

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 12

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 13

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 14

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 15

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 16

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 17

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 18

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 19

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 20

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);
