Question 4

A developer is using Salesforce CLI to create a temporary environment for feature development and testing that includes all source code and shape settings. Which CLI command should the developer use to create this temporary environment?

Accepted Answer

sf org create scratch. sf org create scratch creates a scratch org based on a definition file.

Question 5

sf project deploy start. The 'sf project deploy start' command is the current standard for deploying source to an org.

Answer

sf org create

Answer

Answer

sf org login

Question 6

A developer wants to include a custom styling hook to override a standard Lightning Design System component token in a Lightning Web Component. Where should this CSS custom property be defined?

Accepted Answer

In the component's cascading style sheet file (.css). Lightning Web Components use standard CSS custom properties (design tokens) to allow styling overrides, and these must be defined in the component's .css file. The CSS file is where SLDS styling hooks are declared, scoped to the component's shadow DOM, so the override applies only to that component.

Answer

Inside the component controller JavaScript file (.js)

Answer

In a separate Static Resource uploaded to Salesforce

Answer

In the component's configuration file (.js-meta.xml)

Question 7

A developer needs to see how much memory a specific Apex method is consuming. Which log category should be adjusted?

Accepted Answer

Profiling.. The Profiling log category in Salesforce debug logs captures granular performance data, including memory consumption, CPU time, and method-level execution details. Adjusting the Profiling category to the appropriate level (e.g., FINEST) provides the heap and memory usage information needed to analyze a specific Apex method's resource consumption.

Answer

Apex Code.

Answer

Database.

Answer

Workflow.

Question 8

A developer is writing a Visualforce page with custom controller logic and needs to ensure that database operations are executed transactionally. What happens by default when an unhandled exception occurs during a controller action method?

Accepted Answer

The entire transaction is rolled back.. In Visualforce with a custom controller, an unhandled exception during a controller action method causes the entire transaction to roll back by default. Salesforce wraps the request in a database transaction, so any DML performed before the exception is undone, preserving atomicity.

Answer

The user is redirected to the login page.

Answer

Only partial records are saved; successful ones are committed.

Answer

Changes are committed and an email is sent to the admin.

Question 9

A developer is writing a Visualforce page and wants to display messages generated by controllers or validation rules. Which component should be used?

Accepted Answer

. displays all messages queued on the page for the current request.

Answer

<apex:errorMessages />

Answer

<apex:outputPanel type="messages" />

Answer

<apex:messageLog />

Question 10

A developer is implementing a Lightning Web Component with a custom CSS file. How does the component load its associated stylesheet?

Accepted Answer

Automatically by sharing the exact base file name in the same component bundle folder.. In a Lightning Web Component bundle, the CSS file is loaded automatically when it shares the exact base file name with the component and resides in the same bundle folder. For example, `myComponent.css` alongside `myComponent.js`, `myComponent.html`, and `myComponent.js-meta.xml` is applied automatically — no import or link tag is needed.

Answer

By declaring the stylesheet in the component's js-meta.xml configuration file.

Answer

By importing the CSS file explicitly at the top of the JavaScript file using an import statement.

Answer

Using a <link rel="stylesheet"> tag inside the component HTML template.

Question 11

Which TWO of the following are valid deployment tools?

Accepted Answer

Salesforce CLI.. Salesforce CLI (A) is a valid deployment tool because it provides command-line commands such as 'sf project deploy start' (formerly 'sfdx force:source:deploy') that push metadata and source from a local project to an org, supporting both source and metadata formats. Change Sets (B) are a valid deployment tool because they let you bundle metadata components in a source org and deploy them to a target org through the Setup UI, typically between related orgs such as sandbox to production. The other options are not deployment tools: System Log (C) is a monitoring/diagnostic feature for viewing execution logs, Developer Console Debugger (D) is used to inspect and troubleshoot Apex and other code at runtime, and Apex Test Runner (E) is for executing Apex tests to validate code, not for moving metadata between orgs.

Answer

System Log.

Answer

Developer Console Debugger.

Answer

Apex Test Runner.

Question 12

Which collection type stores elements as key-value pairs in Apex?

Accepted Answer

Map. A Map stores key-value pairs where each unique key maps to a single value.

Answer

Set

Answer

Array

Answer

List

Question 13

A developer has an Aura component that needs to communicate with an unrelated Lightning Web Component located on the same Lightning page. Which feature should the developer implement?

Accepted Answer

Lightning Message Service (LMS). The Lightning Message Service (LMS) allows communication between Visualforce pages, Aura components, and Lightning Web Components across the DOM.

Answer

Aura Component Events (app events)

Answer

A shared JavaScript closure via window globals

Answer

Direct DOM traversal using document.querySelector()

Question 14

A developer is building a Lightning Web Component that includes user input fields. To adhere to best practices for accessibility and SLDS form styling, how should form inputs be structured?

Accepted Answer

Use SLDS form element containers with corresponding or HTML input elements paired with explicit labels.. SLDS provides form element containers (slds-form-element, slds-form-element__label, slds-form-element__control) that pair labels with inputs for correct spacing, alignment, and screen-reader association. Using lightning-input (which renders SLDS-compliant markup with built-in label support) or native HTML inputs wrapped in these SLDS containers with explicit associations satisfies both accessibility and styling best practices.

Answer

Use standard HTML inputs without associated label elements.

Answer

Use <table> tags for layout alignment of form fields.

Answer

Apply inline CSS display:flex directly to raw text areas.

Question 15

A developer needs to execute lightweight asynchronous logic that is chainable and allows passing complex objects to the background job. Which asynchronous feature should the developer implement?

Accepted Answer

Queueable Apex. Queueable Apex supports complex member variables including sObjects and custom Apex types, and it can be chained. Future methods only support primitive types and collections of primitive types.

Answer

Schedulable Apex

Answer

Future methods

Answer

Batch Apex
