Answer

Future Methods

Answer

Queueable Apex

Answer

Schedulable Apex

Question 2

A developer is deploying metadata from a sandbox to a production org using Salesforce CLI. Which command should the developer use to validate the deployment without actually saving components to the target organization?

Accepted Answer

sf project deploy start --dry-run. The sf project deploy start command includes a dry-run or check-only validation flag. In modern Salesforce CLI (sf), it is --dry-run.

Answer

sf project retrieve start --validate

Answer

sf project deploy validate

Answer

sf org check deploy

Question 3

A developer needs to write a unit test to verify that a trigger correctly inserts related Task records when a custom object record is created. Which annotation should the developer place on the test class method to ensure it runs correctly and can access existing org data if needed?

Accepted Answer

@isTest. The @isTest annotation identifies a method or class as containing unit tests. Using @isTest(SeeAllData=true) is sometimes required when legacy data must be accessed, though best practice is to create test data locally.

Answer

@ReadOnly

Answer

@TestVisible

Answer

@TestSetup

Question 4

A batch Apex class processes 50,000 records. During the execute method, a custom governor limit is approached. Which method can the developer call to check the remaining CPU time dynamically?

Accepted Answer

Limits.getCpuTime(). Limits.getLimitCpuTime() and Limits.getCpuTime() allow developers to monitor resource usage dynamically.

Answer

System.getCPU()

Answer

AsyncApexJob.getCpuTime()

Answer

BatchContext.getCpuTime()

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.

Future Methods

Question 6

A developer is writing a unit test and needs to assert that a specific custom exception was thrown during invalid input processing. Which pattern should the developer use?

Accepted Answer

Wrap the target code in a try block, add Assert.fail('Expected exception') after the target code, and catch the exception.. Using try-catch blocks with System.assert or Assert.fail inside the try block ensures that if the exception is not thrown, the test fails.

Answer

Use Test.expectException() before calling the method.

Answer

Check Limits.getScriptStatements() after the method call.

Answer

Use System.assert(false, e.getMessage()) inside the catch block.

Question 7

Which THREE statements are true regarding asynchronous Apex governor limits and execution behavior? (Choose three.)

Accepted Answer

Asynchronous Apex jobs execute in their own separate transaction with independent governor limits.. Asynchronous jobs have higher limits (heap, CPU time), run in separate transactions, and can be monitored via AsyncApexJob.

Answer

Future methods can be chained indefinitely without any depth limitations.

Answer

Batch Apex jobs cannot make external web service callouts.

Question 8

Which TWO of the following are valid ways to execute Apex unit tests in Salesforce?

Accepted Answer

Developer Console. Tests can be run via the Developer Console or the Apex Test Execution page in Setup.

Answer

Object Manager settings

Answer

User Management settings

Answer

Change Sets menu

Question 9

Which feature allows administrators to invoke an Apex method from a Flow?

Accepted Answer

@InvocableMethod. The @InvocableMethod annotation exposes Apex methods to flows and process builder.

Answer

@RemoteAction

Answer

@future

Answer

@AuraEnabled

Question 10

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 11

Which TWO features are characteristic of Flow Builder compared to Apex triggers? (Choose two.)

Accepted Answer

Flows provide a visual canvas for building automation logic without writing code.. Flow Builder is declarative, provides visual debugging, and allows point-and-click creation.

Answer

Flows execute entirely on client-side browsers.

Answer

Flows require compilation into bytecode and deployment via metadata APIs or developer toolchains.

Answer

Flows cannot interact with custom objects or custom fields.

Question 12

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 13

A developer is analyzing a debug log and notices that it is truncated because it exceeded the maximum file size limit. Which action should the developer take to capture only the relevant Apex code execution details without exceeding the limit?

Accepted Answer

Adjust the Trace Flag log levels to reduce verbosity for unnecessary categories like Database and Workflow.. Refining log categories and levels ensures only necessary debug statements are recorded, preventing truncation.

Answer

Increase the maximum log file size in company profile settings.

Answer

Disable all validation rules in the org temporarily.

Answer

Switch the debug log perspective to 'Development Harvester'.

Question 14

Which governor limit applies specifically to the total number of asynchronous Apex executions (such as future methods and queueable jobs) enqueued in a 24-hour period for an Enterprise Edition org?

Accepted Answer

10,000 or 2.5 times the number of user licenses, whichever is greater. The asynchronous Apex execution limit restricts the total number of future calls, queueable jobs, and scheduled jobs that can be enqueued per 24 hours.

Answer

100 SOQL queries per transaction

Answer

6MB heap size limit

Answer

50 DML statements per transaction

Question 15

A developer has an Apex trigger that fires on Account update. Inside the trigger, it calls a future method to update related Contact records. During testing with 150 Account records modified simultaneously, the developer receives a System.LimitException: Too many future calls. What is the cause of this exception?

Accepted Answer

The trigger exceeded the maximum limit of 50 future method calls per Apex transaction.. Future methods cannot be called from within other asynchronous contexts or inside triggers when the trigger processes more records than the future call limit allows per transaction (e.g. max 50 future calls per transaction).

Answer

The total daily asynchronous limit was reached.

Answer

Future methods cannot be invoked from inside an Apex trigger context.

Answer

The future method tried to execute a SOQL query exceeding the limit.

Question 16

A developer needs to display a toast notification in a Lightning Web Component when a record is successfully saved. Which module should the developer import?

Accepted Answer

import { ShowToastEvent } from 'lightning/platformShowToastEvent';. Lightning Toast notifications are triggered by importing ShowToastEvent from 'lightning/platformShowToastEvent'.

Answer

import { Toast } from 'lightning/toast';

Answer

import ShowToast from 'force:showToast';

Answer

import { showNotification } from 'lightning/notificationsLibrary';

Question 17

Which TWO tools or APIs can a developer use to deploy metadata between Salesforce organizations? (Choose two.)

Accepted Answer

Outbound and Inbound Change Sets. Change Sets and the Metadata API (via CLI or IDEs) are primary tools for metadata deployment.

Answer

Data Loader

Answer

Apex Anonymous Windows

Answer

Process Builder

Question 18

If a developer uses 'SeeAllData=true' in a test class, what are the primary risks?

Accepted Answer

It makes tests dependent on the state of the organization's existing data.. It relies on existing organization data, making tests brittle and dependent on external state.

Answer

It prevents the use of Test.startTest().

Answer

It causes the Apex compiler to error.

Answer

It increases the test execution time significantly.

Question 19

A developer receives a System.LimitException: Too many SOQL queries: 101 when running a complex unit test. The test class inserts a large volume of test records that inadvertently cause a trigger to execute multiple queries inside a loop. What is the most effective way to reset the governor limits specifically for the code being tested?

Accepted Answer

Wrap the test assertion code between Test.startTest() and Test.stopTest().. Test.startTest() resets all governor limits for the code executed immediately following it, up until Test.stopTest().

Answer

Mark the test method with @isTest(SeeAllData=true).

Answer

Wrap the trigger logic in a Database.setSavepoint() block.

Answer

Use Limits.getLimitQueries() inside the test method.

Question 20

A developer needs to write a test class for a Batch Apex job. Which method must be called to verify that the batch job executes correctly?

Accepted Answer

Database.executeBatch() enclosed by Test.startTest() and Test.stopTest(). Database.executeBatch inside Test.startTest() and Test.stopTest() executes the batch job in test context.

Answer

Test.runBatch()

Answer

Test.enqueueJob()

Answer

System.runAs()
