B2B-Commerce-Developer Practice Test Questions

Explanation:

In Salesforce B2B Commerce, storefronts can be customized with themes stored in Static Resources. Admins choose themes in the CC Admin console, but not every uploaded resource shows up in the theme section. For a theme to appear, it must follow a specific naming convention so the system can detect and list it properly.

Correct Option:

✅ C. The theme needs to have "theme" in the name of the Static Resource
Salesforce B2B Commerce identifies available themes by scanning Static Resources. Only those with "theme" in their name are recognized and displayed in the Theme dropdown of CC Admin. This rule prevents non-theme resources from showing up and keeps the admin selection clean. Without this naming, your uploaded files won’t be selectable, even if the resource itself is valid.

Incorrect Options:

❌ A. The theme needs to be set as a Custom Setting in Salesforce
Custom Settings are meant for configuration values that developers or admins can reference in code or logic. They don’t control which resources appear as selectable themes. Even if you store a theme name in a Custom Setting, it won’t make it show up in CC Admin’s theme list.

❌ B. The theme needs to be set in the Configuration Settings
Configuration Settings govern storefront behaviors like pricing, ordering, or product display. They don’t dictate which Static Resources get pulled into the theme selection menu. Adding a theme here won’t register it for use in the theme section.

❌ D. The theme needs to be referred to in the head element on the page
Referencing a theme in the head element may help load styling on a page, but it doesn’t influence whether CC Admin detects the theme as an option. Detection happens only via the Static Resource naming convention.

Explanation:

Lightning Web Components (LWCs) are modular, reusable building blocks in Salesforce, designed for modern web development. Each LWC, like myComponent, requires specific files to define its structure, logic, and configuration. These files work together to render the component in Salesforce environments, such as Lightning pages. Understanding the essential files ensures developers can create and deploy components effectively, leveraging standard web technologies and Salesforce’s metadata-driven architecture for seamless integration.

Correct Options:

A. myComponent.html ✅:
The myComponent.html file is the core template for an LWC, defining its visual structure using standard HTML within a template tag. It determines what users see, such as buttons or text, and binds data to the component’s logic. Without this file, the component cannot render its UI, making it a critical piece of the LWC bundle for display and interaction in Salesforce.

C. myComponent.js-meta.xml ✅:
The myComponent.js-meta.xml file configures the component’s metadata, specifying its API version, description, and where it can be used (e.g., Lightning App Builder or Experience Cloud). This file ensures the component is properly recognized and deployed in Salesforce. It’s essential for defining the component’s behavior and visibility, enabling integration with various Salesforce features and ensuring compatibility across environments.

E. myComponent.js ✅:
The myComponent.js file contains the JavaScript logic for the LWC, defining its functionality through a class that extends LightningElement. It handles data, events, and lifecycle methods, making the component dynamic and interactive. This file is vital as it powers the component’s behavior, connecting the UI to Salesforce data and logic, ensuring the component performs as intended in user interactions.

Incorrect Options:

B. myNewComponent.css ❌:
A CSS file, typically named myComponent.css to match the component, is optional in an LWC bundle. It’s used for custom styling but isn’t required, as components can rely on Salesforce’s Lightning Design System (SLDS) for default styles. The mismatch in naming (myNewComponent.css) further indicates it’s not part of the myComponent bundle, making it irrelevant to the essential files needed for the component’s core functionality.

D. myComponent.aura ❌:
The myComponent.aura file is associated with Aura components, not Lightning Web Components. LWCs use a different framework with .html, .js, and .js-meta.xml files, while Aura uses .cmp files. This file is incorrect as it belongs to an entirely different component model, incompatible with the LWC structure, and cannot contribute to the functionality or deployment of myComponent.

Explanation:

In B2B Commerce, product data is managed in the Salesforce backend within catalogs. Changes made to products are staged in the platform's database but are not automatically pushed to the live storefront. A specific publishing action is required to synchronize this data and make the updated product information visible to storefront users, ensuring a controlled deployment process.

✅ Correct Option: D. Publish the catalog
Products are organized within catalogs. Any modification to a product's details, such as price, description, or imagery, is only reflected on the live site after the specific catalog containing that product is published. This action pushes the updated data from the backend database to the active storefront, making the changes publicly visible.

❌ Incorrect Options:

A. Activate the product list.
A product list is a curated collection of products used for merchandising (e.g., "Featured Products"). Activating it only controls the visibility of that specific list on pages, not the underlying product data itself. The core product information remains unchanged and unpublished.

B. Publish the storefront.
This action deploys changes to the storefront's code, metadata, and page compositions (like LWCs or Aura components). It is unrelated to publishing data records such as products, prices, or catalogs to the site.

C. Rebuild the search index.
Rebuilding the index makes newly published product data searchable. However, it is a subsequent step. If the catalog itself hasn't been published first, the search index has no new data to process, so the changes will remain invisible in both browse and search.

Explanation:

A developer is building a custom Lightning Web Component (LWC) for a Salesforce B2B Commerce storefront. This component must display text that needs to be translated into multiple languages to support the different locales of the storefront's users. The challenge is to find the most efficient and standard way to handle these language-specific strings directly within the LWC framework, ensuring the text dynamically changes based on the user's selected language.

Correct Option: C 🏆
Creating custom labels for text values and importing them into the LWC is the standard and most effective method. Custom labels are a powerful Salesforce platform feature designed specifically for this purpose. They are platform-native, translatable, and accessible from various components, including LWCs. By importing the labels directly into the component's JavaScript, the developer can reference them, and Salesforce's localization service will automatically display the correct translation based on the user's language settings. This approach is highly scalable and maintainable.

Incorrect Options

A. ❌ Import static resources for the text values and add them into the LWC.
While static resources can store files like JSON or XML for text, they are not designed for easy, platform-native translation. A developer would have to manually manage multiple files for each language and implement custom logic to detect the user's language and load the correct file. This is a cumbersome, non-standard approach that bypasses Salesforce's built-in localization features, leading to increased development effort and maintenance overhead.

B. ❌ Use a CustomLabel xml file in the LWC to add the text values there.
This option describes a non-existent feature. There is no standard Salesforce mechanism for including a CustomLabel.xml file directly within an LWC bundle to define new labels. Custom Labels are a platform-level feature managed through the Salesforce setup UI or metadata API, not through individual component files. Attempting this would result in a deployment error as the format and placement are incorrect according to the LWC framework rules.

D. ❌ Create a custom Metadata object for the text values and query it in the LWC.
Although custom metadata objects can store configuration data, including text, using them for simple translatable strings is not the best practice. This approach requires a SOQL query to retrieve the data, which adds unnecessary complexity and can impact performance due to an extra server-side call. Custom labels are directly accessible in the LWC's JavaScript without a query, making them a far more performant and straightforward solution for localization.

Explanation:

When building Lightning Web Components (LWC), developers often need object metadata — things like record types, default values, and field accessibility. Salesforce provides specific wire adapters to access this information without manual Apex calls. Choosing the correct adapter ensures efficient metadata retrieval and keeps the component lightweight.

Correct Option

✅ B. getObjectInfo
The getObjectInfo wire adapter in lightning/uiObjectInfoApi retrieves metadata about a given object, including default record type IDs, label information, and field details. This is the official and supported method to pull object-level metadata in LWC. Developers can pass the API name of the object, and the adapter handles everything without needing SOQL queries or Apex code.

Incorrect Options

❌ A. getObjectMetadata
This sounds plausible but doesn’t exist in the Lightning Data Service API. It’s a common trap because the name looks logical, yet the real adapter is getObjectInfo. Using this would result in errors since Salesforce doesn’t provide such a wire adapter.

❌ C. getObject
The getObject option is misleading. It doesn’t exist in the UI API. Developers may confuse it with getRecord (used to fetch record data), but that serves a different purpose — fetching actual record fields, not metadata about the object itself.

❌ D. getObjectDescribe
This mimics the classic Apex Schema.Describe methods but isn’t available as a wire adapter. In Apex, you’d use describe calls for metadata, but in LWC the correct API is getObjectInfo. Mixing the two contexts is a common error when moving from Apex to LWC.

Explanation:

In Lightning Web Components (LWC), decorators enhance JavaScript classes by adding special behaviors to properties or methods, making development more efficient and reactive. They enable public APIs, data tracking, and seamless integration with Salesforce data services. Selecting the right decorators is key for building performant, interactive components that respond to user actions and data changes, ensuring smooth communication between parent-child components and the Salesforce backend.

Correct Options:

A. @api ✅:
The @api decorator exposes a class field as a public property, forming part of the component's API. This lets parent components pass data or call methods on child components via dot notation. It's essential for inter-component communication, ensuring values are reactive and trigger rerenders when updated. Without @api, properties stay private, limiting reusability and integration in larger Salesforce apps.

B. @track ✅:
@track makes a field reactive, especially for objects or arrays, by tracking deep changes to their internal structure. Though most fields are reactive by default since Spring '20, @track is still needed for nested mutations in primitives or complex data. It helps components update efficiently without full reloads, keeping the UI in sync with dynamic data flows in Salesforce environments.

C. @wire ✅:
The @wire decorator connects components to Salesforce data via wire adapters or Apex methods, providing reactive streams of information. It automatically rerenders the component on data updates, handling loading states and errors gracefully. This simplifies data fetching from Lightning Data Service or custom controllers, making it a go-to for building data-driven UIs without manual polling.

Incorrect Options:

D. @class ❌:
@class isn't a recognized decorator in LWC; JavaScript's class syntax handles component definitions natively by extending LightningElement. Attempting to use it would cause errors, as LWC relies on standard ES6 classes without needing extra decoration for the class itself. Stick to built-in decorators for properties and methods to avoid compatibility issues in Salesforce deployments.

E. @import ❌:
@import doesn't exist as a decorator in LWC—imports use standard JavaScript 'import' statements for modules like wire adapters. Decorators target class members, not imports, so this would break code compilation. Confusing it with CSS @import or JS modules is common, but LWC enforces clean ES modules for better modularity and tree-shaking.

Explanation:

In Salesforce B2B Commerce, data is retrieved via APIs. When querying custom relationships, the platform's transformation engine automatically converts the complex Salesforce API relationship names into a more standardized, predictable, and JavaScript-friendly JSON object notation for easier use within scripts and components.

✅ Correct Option: C. myRelationshipNameR=>(myName: value)
B2B Commerce employs a specific transformation logic. It converts the __r relationship suffix to a capital 'R' and uses the => operator to denote the relationship traversal. The custom field __c is changed to camelCase. This structured format allows for clear, nested object navigation in the resulting JSON data model, such as product.myRelationshipNameR.myName.

❌ Incorrect Options:

A. myrelationshipname.myname: value
This format is incorrect because it uses all lowercase and removes the significant 'R' denoting a relationship. The transformation does not simply lower-case everything; it follows a specific camelCase convention and retains the relationship identifier.

B. myRelationshipName.myName: value
This is close but incorrect as it misses the crucial relationship indicator. The API suffix __r is explicitly transformed into a capital 'R' (e.g., relationshipNameR), not just removed. This 'R' is a key signal for developers that this is a related object.

D. My_Relationship_Name__r.My_Name__c: value
This option is the raw API name, not the transformed JSON structure. B2B Commerce does not return the data with the original underscores and suffixes; it processes it into a cleaner, more developer-friendly format for use in the storefront logic.

Explanation:

When a transaction, such as saving a record or executing a custom process, occurs in Salesforce, the platform generates a debug log to provide a detailed, step-by-step account of what happened. These logs break down the entire process into smaller, manageable pieces called "code units" or "discrete units of work." These units represent specific, trackable events within the transaction's lifecycle, allowing developers to trace the exact flow of execution and identify where issues might be occurring.

Correct Options:

C. Web service invocation ⚙️
A web service invocation is a distinct and measurable unit of work because it involves a callout to an external system. The Salesforce debug log tracks this specific operation from start to finish. It logs details about the request sent to the external service and the response received. This is critical for debugging integrations, as it clearly isolates the time and resources spent on communicating outside the Salesforce platform, separate from any other internal code execution.

D. Apex class 🧩
The execution of an Apex class is a primary example of a discrete unit of work. When a method within an Apex class is called—for instance, from a trigger or a web service—the debug log records the beginning and end of this execution using the CODE_UNIT_STARTED and CODE_UNIT_FINISHED events. This encapsulates all the custom business logic, SOQL queries, and DML operations performed by that specific class, making it a perfectly contained and trackable unit of code execution within the larger transaction.

Incorrect Options:

A. ❌ Validation rule
While a validation rule's evaluation is indeed logged as an event within a transaction, it is not considered a top-level "discrete unit of work" in the same way a custom Apex class or callout is. Its execution is a standard part of the DML save order, and while the log shows if a rule fired (VALIDATION_RULE), it's a smaller, more granular event that's nested within the overall DML process, rather than a standalone, developer-defined code block.

B. ❌ Lightning component load
A Lightning component load is a client-side event that happens in the user's browser, not on the Salesforce server where debug logs are generated. While a component's load might trigger server-side calls (e.g., to an Apex controller), the act of the component itself loading is not a server-side "discrete unit of work" that would appear in a debug log. The log would instead show the Apex method calls that were initiated by the component, not the component's front-end rendering.

Salesforce Developer Documentation: Debug Log Details

Explanation:

Salesforce B2B Commerce (CloudCraze) storefronts are built on a managed package that leverages a mix of front-end frameworks for templating, styling, and client-side logic. Knowing which frameworks are in play is important for developers extending or customizing storefront experiences since it dictates which conventions and tools are available out of the box.

Correct Option

✅ B. Bootstrap, Backbone.js, and Handlebars.js
CloudCraze relies on Bootstrap for responsive CSS design and layout, Backbone.js for structuring JavaScript code with models and views, and Handlebars.js for dynamic templating. This trio provides a clean separation of responsibilities: styling, client-side logic, and templating. Developers extending CloudCraze themes or storefronts are expected to understand these frameworks to build consistent and maintainable features.

Incorrect Options

❌ A. AngularJS, Backbone.js, and Handlebars.js
AngularJS is not part of the CloudCraze package. While it is a popular JavaScript framework, CloudCraze instead uses Bootstrap for styling and responsiveness. Including AngularJS here is a distractor because it overlaps in purpose with Backbone.js.

❌ C. Bootstrap, AngularJS, and Backbone.js
This mix leaves out Handlebars.js, which is central to the templating system CloudCraze uses. AngularJS again doesn’t belong in the architecture, and without Handlebars, the option misses the framework that handles the dynamic rendering of HTML.

❌ D. AngularJS, React.js, and Handlebars.js
Neither AngularJS nor React.js is included in the managed package. CloudCraze predates React adoption and never relied on it. This option might trick someone familiar with modern frontend stacks, but it doesn’t match the CloudCraze reality.

Explanation:

In Salesforce B2B Commerce, Order Summary records represent completed orders from the storefront, linked to underlying Order records for fulfillment. Exporting these via Data Loader relies on SOQL queries that respect user permissions and record visibility. Missing records during export often stem from access restrictions in multi-account B2B setups, where sharing rules limit what the exporting user can query, ensuring data security while allowing bulk operations for analysis or migration.

Correct Options:

C. The user does not have rights to some of the records ✅:
In B2B Commerce, Order Summary records are shared based on account-specific rules, often controlled by criteria or role hierarchies to protect sensitive buyer data. If the developer lacks "Read" access to certain records—due to ownership by other accounts or insufficient profile permissions—Data Loader's SOQL query won't retrieve them, leading to incomplete exports. This is common in orgs with multiple buyer accounts, emphasizing the need for elevated permissions or explicit sharing for full visibility.

Incorrect Options:

A. The export job did not fully complete ❌:
Data Loader provides clear status indicators, logs, and success/failure counts after each export run. If the job didn't complete, the developer would see partial results or error messages, not just "some" records missing without alerts. In B2B Commerce, exports of Order Summaries typically process quickly for unmanaged types, so incomplete jobs are less likely without obvious signs like network interruptions or batch size issues.

B. Order Life Cycle Type was Managed ❌:
B2B Commerce primarily uses unmanaged Order Summaries (Life Cycle Type 'UNMANAGED') for storefront orders, which are exportable via Data Loader with proper SOQL filters. Managed types are for external order management systems like Salesforce Order Management, but even then, records aren't inherently missing—exports would include them unless filtered out. The scenario implies standard B2B orders, so this type mismatch isn't the primary cause of omissions.

D. The Status was still set to Draft ❌:
Draft Order Summaries represent unconfirmed carts or incomplete checkouts, but in B2B Commerce, exports via Data Loader target completed orders by default, often filtering for statuses like 'Order Confirmed' or 'Fulfillment In Progress'. Draft records are visible and queryable if access allows, so missing ones would more likely tie to permissions rather than status alone, as the dev noticed "orders" (implying placed ones) were absent.
