Question 1

When implementing a trigger framework for the Contact object, which two practices should a developer follow to ensure the solution is scalable and maintainable? (Select Two)

Accepted Answer

Create a single, well-structured trigger for the Contact object., Place all business logic directly within the trigger file., Move business logic into a separate Apex handler class., Create multiple triggers on the Contact object, one for each major business process., Use future methods to handle all DML operations to avoid governor limits.

Question 2

What is the correct Apex method signature for an invocable action that accepts a list of Contact IDs from a Flow, processes them, and returns a corresponding list of custom `ContactResult` wrapper objects?

Accepted Answer

@InvocableMethod public static Map processContacts(List contactIds) {}, @InvocableMethod public static List processContacts(List contactIds) {}, @InvocableMethod public static void processContacts(List contacts) {}, @InvocableMethod public static ContactResult processContacts(Id contactId) {}

Question 3

A developer is tasked with creating a wizard-style interface on an Account page to guide sales reps through a complex qualification process. The interface must present different questions and data entry fields based on the rep's previous answers. Which declarative feature should be used to meet this requirement?

Accepted Answer

Dynamic Forms, Record-Triggered Flow, Approval Process, Screen Flow

Question 4

A developer has implemented a trigger that sends an email notification. To avoid sending actual emails during test execution, this functionality must be bypassed. Which Apex system method should be used within the trigger's helper class to conditionally prevent the email send logic from executing during a test run?

Accepted Answer

System.isBatch(), System.isFuture(), Test.isExecuting(), Test.isRunningTest()

Question 5

An Apex trigger on the Opportunity object performs a DML update on a custom field of its parent Account in an 'after update' context. The Account object also has an 'after update' trigger that updates a summary field on all its child Opportunity records. What is the most significant risk a developer must mitigate in this design?

Accepted Answer

Uncontrolled trigger recursion leading to a 'Maximum trigger depth exceeded' error., The transaction will fail due to mixed DML operations., A deadlock will occur as both objects attempt to lock each other for updates., Cross-object DML operations are not permitted between parent and child records in the same transaction.

Question 6

A developer is designing a data model for a manufacturing application where child `Equipment__c` records must inherit ownership from a parent `Maintenance_Cycle__c` record and be automatically deleted if the parent is deleted. Which relationship type should be created on the `Equipment__c` object?

Accepted Answer

Hierarchy, Master-Detail, Lookup, Junction

Question 7

A developer has created a nested structure of Lightning Web Components. A child component, `c-action-button`, is nested inside a parent component, `c-action-panel`, which is itself placed within a top-level component, `c-page-container`. To notify the top-level component of a user action, a custom event must be dispatched from `c-action-button` and handled by an event listener on `c-page-container`. Which event configuration is required to ensure the event can be handled by the ancestor component across the Shadow DOM boundaries?

Accepted Answer

bubbles: true, composed: true, bubbles: true, composed: false, bubbles: false, composed: true, detail: { data }, cancellable: true

Question 8

An elusive bug within an Apex trigger is reproducible only by a single user. To analyze the execution path and variable values during that user's specific transaction, which tool should be used to capture a targeted, real-time debug log?

Accepted Answer

VS Code with the Salesforce Extension Pack by replaying a debug log, Salesforce CLI by running an Apex test with the user's context, The 'Debug Logs' page in Setup to define a global trace flag, Developer Console using the Logs tab and setting a trace flag for the user

Question 9

When implementing a call to an Agentforce action from an Apex class, how should a developer handle the response to ensure the solution is robust?

Accepted Answer

Hardcode the expected response structure into the Apex class for consistency., Use a future method to guarantee the response is received within governor limits., Assume the response will always be valid JSON and directly deserialize it., Wrap the call in a try-catch block and check for null or error states in the response before processing.

Question 10

Two Lightning Web Components exist on the same page but in different DOM branches, preventing direct event bubbling. What is the standard, loosely coupled communication pattern for one component to notify the other of a state change?

Accepted Answer

Dispatch a custom event with the `bubbles: true` and `composed: true` properties., Call an Apex method imperatively from the source component to publish a Platform Event, which the target component subscribes to via the `empApi` module., Implement the legacy `pubsub` utility to publish an event from the source and subscribe to it in the target., Utilize the Lightning Message Service (LMS) to send a message on a message channel that the target component subscribes to.

Question 11

When designing a complex application with over ten new interrelated custom objects, a developer needs a visual tool to lay out the objects, view their relationships, and create new fields and relationships directly from the diagram. Which standard Salesforce tool is best suited for this purpose?

Accepted Answer

Object Manager, Schema Builder, App Builder, Developer Console

Question 12

Upon a button click within a Lightning Web Component form, multiple input fields must be validated collectively in JavaScript before any data is sent to the server. What is the most direct approach to access all of these fields for validation?

Accepted Answer

Query all input elements using `this.template.querySelectorAll('lightning-input')` in the button's click handler., Dispatch a custom event from each input field that bubbles up to a single handler., Bind each input field to a property decorated with `@track` and access the properties directly., Use two-way data binding with the `onchange` event to update properties for every keystroke.

Question 13

What is the standard way to make a Lightning Web Component aware of the current record's ID when it is placed on a Lightning record page?

Accepted Answer

Hardcode the record ID in the component's JavaScript file for testing purposes., Expose a public property with the `@api` decorator and rely on the Lightning App Builder to pass the `recordId`., Use an imperative Apex call in the `connectedCallback` to query the record data using the `recordId`., Use the Lightning Message Service to subscribe to a channel that broadcasts the current record's data.

Question 14

Review the following Apex trigger snippet that runs after an Asset is inserted. What are the two primary best practice violations in this code?

trigger AssetTrigger on Asset (after insert) {
    for (Asset a : Trigger.new) {
        Account parentAccount = [SELECT Id, Name FROM Account WHERE Id = :a.AccountId];
        parentAccount.Last_Asset_Added_Date__c = Date.today();
        update parentAccount;
    }
}
(Select Two)

Accepted Answer

A SOQL query is executed inside a for loop., A DML statement (update) is executed inside a for loop., The trigger logic is in the 'after insert' context instead of 'before insert'., The code does not use Trigger.newMap., The variable 'parentAccount' is not declared outside the loop.

Question 15

Closing a Case record with a specific Reason must initiate a callout to an external ERP system's non-bulk API. Which automation solution performs this action for each Case while respecting platform constraints?

Accepted Answer

A before-save record-triggered Flow that makes the callout directly using an HTTP Callout action., A record-triggered Flow that calls an invocable Apex method with a @future(callout=true) annotation., A screen Flow launched from a custom action on the Case layout., An Apex trigger that directly performs a synchronous callout.

Question 16

To accelerate the development of a new feature, a team decides to use Agentforce for Developers to generate Apex unit tests for their service classes. What are two critical limitations the developers must account for when using the generated tests? (Select Two)

Accepted Answer

The generated tests will always fail to meet the 75% code coverage requirement., The generated tests may not cover all relevant business edge cases or negative scenarios., Agentforce is unable to create mock responses for callouts within a test context., The generated tests require manual validation to ensure they correctly assert the intended business logic., Agentforce cannot generate test data using Test.loadData().

Question 17

In order to adhere to a strict change management policy, a deployment must be pre-validated against the production environment two days before the go-live date. Which deployment mechanism directly facilitates this requirement and allows for a faster deployment later?

Accepted Answer

Creating an outbound change set without uploading it., Refreshing a Full sandbox from production before deployment., Using the 'Validate' option on an inbound change set., Performing a sandbox-only deployment for review.

Question 18

When implementing a complex calculation method in an Apex class, what are the primary effects of using the `return` statement? (Select Two)

Accepted Answer

It passes a value back to the calling scope if the method has a non-void return type., It transfers control to the `finally` block of a `try-catch` statement if present., It commits all pending DML operations before exiting the method., It exits only the innermost loop, similar to a `break` statement., It immediately terminates the execution of the current method.

Question 19

In which of the following scenarios would a `do-while` loop be a more appropriate choice than a `while` loop or a `for` loop? (Select Two)

Accepted Answer

Generating a unique random number for a record and ensuring the generated number does not already exist in a set of used numbers., Traversing a complex trigger handler framework where the execution order is predetermined., Querying for child records in batches of 200 until all child records for a parent have been processed., Calling an external web service repeatedly until a success message is received, ensuring the first call is always made., Iterating through a known list of Account records to update a field.

Question 20

When working within a Salesforce DX project, a developer uses the org browser in VS Code to make a metadata change directly in their connected scratch org. To incorporate this change into their local project source, what is the standard Salesforce CLI command that must be run?

Accepted Answer

sf project generate manifest, sf config set target-dev-hub, sf project deploy start, sf project retrieve start
