Salesforce B2C-COMMERCE-DEVELOPER Online Practice Questions and Exam Preparation

Salesforce B2C-COMMERCE-DEVELOPER Online Questions & Answers

• Question 1:

  A developer is asked to improve the maintainability of a page by reducing its code repetition.

  What are two techniques the developer should implement to achieve this? Choose 2 answers.

  A. Require and render templates with tags
  B. Uselocal template includes
  C. Implement template decorators paired with replace tags
  D. Embed partial files using ISML expressions
  B. Uselocal template includes
  C. Implement template decorators paired with replace tags

  ---

  explanation: To improve the maintainability of a page by reducing code repetition, the developer should: B. Use local template includes - This technique involves creating smaller, reusable templates for common parts of the page, which can then be included as needed across different templates. This reduces redundancy and makes the codebase easier to manage. C. Implement template decorators paired with replace tags - Template decorators allow developers to define common layout or structural elements that can be reused across different parts of the application. Replace tags can be used within these decorators to specify where unique content should be inserted, further reducing the need to duplicate structural code.

• Question 2:

  A Digital Developer has been given a requirement to add fault tolerance to an existing web service integration that uses Service Framework. Administrators at Universal Containers need to be able to configure the timeout and rate limiting.

  Which approach should the Developer use to implement the requirement?

  A. Implement a ServiceUnavailableException exception handler to execute fallback code.
  B. Implement a condition that checks to see if the response was empty and execute fallback code if true.
  C. Create a site preference to store timeout settings and implement an IOException handler to execute fallback code
  D. Use the setTimeout method to execute fallback code if the request has NOT completed
  D. Use the setTimeout method to execute fallback code if the request has NOT completed

  explanation: When cartridges are not executing despite being uploaded, it typically indicates an issue with how the server is configured to recognize and use the uploaded cartridges. Option D, "Set the server connection's target version directory to the active code version," is the correct action because it ensures that the server uses the correct set of cartridges (the ones uploaded) as part of the active code version. This setup is crucial for the proper execution of code on the Salesforce B2C Commerce server. This option resolves the issue by linking the active development work (the uploaded cartridges) with the server's operational environment, ensuring that changes are recognized and executed as part of the active deployment. Other options do not address the issue of ensuring that the uploaded cartridges are recognized and used in the active server environment: Setting the active code version to use the latest compatibility mode (Option A) does not necessarily connect the uploaded cartridges with the server. Removing invalid characters from the code version's name (Option B) or cartridge file and folder names (Option C) addresses different potential issues unrelated to version targeting.

• Question 3:

  Universal Containers wants to associate a region code value with an order to indicate the general area of its destination. This region code must be accessible whenever the order history is displayed.

  What is required toaccomplish this?

  A. Store the region code value in a session variable.
  B. Define a custom attribute on the Order system object type to store the region code value.
  C. Define a custom object type to store the username with the region code.
  D. Store the region code value in the geolocation system attribute of the Order.
  B. Define a custom attribute on the Order system object type to store the region code value.

  ---

  explanation: To associate a region code value with an order in a way that is persistent and accessible whenever the order history is displayed, the best practice within Salesforce B2C Commerce is to use custom attributes on system objects. By defining a custom attribute on the Order system object type, the region code can be stored directly with the order data, ensuring it is available and easily retrievable in any context where order data is accessed. Option B is correct because: Custom attributes are designed specifically for extending the data model of system objects like Order with additional information. This method ensures that the region code is not only saved with the order but is also managed through the platform's standard data handling processes, making it robust and integrated with the order management lifecycle. Other options do not provide a persistent, reliable way to associate data with an order object: A session variable (Option A) is temporary and not suitable for long-term storage of order-related data. Creating a custom object type (Option C) would unnecessarily complicate data retrieval and is not as integrated as using a system object's attribute. Storing the region code in a geolocation system attribute (Option D) is not appropriate since geolocation attributes serve a different purpose.

• Question 4:

  A developer hasa sandbox configured with a service and its profile and credential. Now there is a requirement to allow changes to the service URL manually from the sandbox.

  Which B2C feature should the developer use to achieve the request?

  A. Use the service credentialURL field
  B. Use the service status area, set the override URL checkbox, and then populate the URLfield with the required one.
  C. Use a Sitepreference dedicated for the service URL
  D. Use a Globalpreference dedicated for the service URL
  C. Use a Sitepreference dedicated for the service URL

  ---

  explanation: To enable manual changes to the service URL from a sandbox environment in Salesforce B2C Commerce Cloud, the recommended approach is to use a Site preference dedicated for the service URL. By configuring a Site preference, the developer can easily adjust the service URL directly through the Business Manager without modifying the service profile or credentials. This approach offers flexibility and control, allowing changes to be made dynamically as required by different environments or specific testing needs.

• Question 5:

  A developer is asked to create a controller endpoint that will be used in a client-side AJAX request. Its purposes is to displayupdated information to the user when the request is completed, without otherwise modifying the appearance of the current page.

  According to SFRA practices, which method best supports this objective?

  A. res.json()
  B. res.render()
  C. res.print()
  A. res.json()

  ---

  explanation: In SFRA (Salesforce Reference Architecture), when creating controller endpoints for client-side AJAX requests where updated information needs to be displayed without refreshing or changing the current page layout, the best method to use is res.json() . This method allows the controller to send JSON-formatted response data back to the client, which can be easily handled via JavaScript on the client side. This approach is optimal for asynchronous requests where data needs to be updated dynamically on the page as it does not involve re-rendering the entire page but rather just the relevant data components. This practice is consistent with modern web development standards that focus on enhancing user experience and reducing server load.

• Question 6:

  A Digital Developer extends a system object, Product, andadds a Boolean attribute, "sellable," to it.

  Assuming "prod" is the variable name handling the product, what code can the Developer use to access it?

  A. prod.extended.sellable
  B. prod.sellable
  C. prod.persistable.sellable
  D. prod.custom.sellable
  D. prod.custom.sellable

  ---

  explanation: When extending a system object in Salesforce B2C Commerce, such as adding a new attribute to the Product object, custom attributes are accessed through the custom namespace. Therefore, if a Boolean attribute named "sellable" is added to the Product object, it should be accessed as prod.custom.sellable. This approach is part of the platform's data customization framework, where custom provides a namespace for all user-defined extensions to system objects, ensuring that they do not conflict with existing system properties. Detailed usage and examples of accessing custom attributes can be found in the Salesforce Commerce Cloud Script API documentation under "System Object Types".

• Question 7:

  A retailer notices that the Account Addresses page is showing the wrong shopper's address.

  Which tool should the developerstart with to identify the issue?

  A. Pipeline profiler
  B. Code Profiler
  C. Storefront Toolkit
  D. Reports and Dashboards Module
  C. Storefront Toolkit

  ---

  explanation: To diagnose an issue where the Account Addresses page is showing the wrong shopper's address, the best tool to start with is the C. Storefront Toolkit. This tool allows developers to inspect the storefront's behavior in real-time, providing insights into the rendered content, application state, and session data, which can help identify issues related to shopper context mismanagement or session data errors. It offers a direct view into how data is being presented to the user, making it a first-line tool for diagnosing user-facing issues.

• Question 8:

  Which line of code creates a content slot that can be included on homepage.isml to display on the home page?

  B

  ---

  explanation: To create a content slot that is included on the homepage and displayed correctly, the code should specify the context appropriate to the homepage. The correct line of code, , indicates that the slot is a global type and the context is set to "homepage". This means the content slot 'my_banner' is designed to be used across various pages of the site but specifically renders in the homepage context, aligning with common ISML template practices.

• Question 9:

  A developer uses hooks for an extension point. Which n true for running multiple hooks for an extension point?

  A. It is possible to register multiple modules to call for an extension point in a singlehooks.json file
  B. It is possible to control the order in which registered modules are called.
  C. If you call multiple modules, only the first hook called returns a value
  A. It is possible to register multiple modules to call for an extension point in a singlehooks.json file

  ---

  explanation: In Salesforce B2C Commerce, particularly when using the hooks framework, it is possible to register multiple hooks for a single extension point within a single hooks.json file. This feature allows developers to extend or modify the behavior of the base application by specifying different modules that can be called when a particular event or operation occurs. By defining multiple hooks in the hooks.json file, developers can effectively modularize their customizations, making the system more flexible and easier to maintain. Each registered module can be triggered in sequence based on the configuration, providing extensive control over the application's flow and functionalities.

• Question 10:

  A client has a requirement to render different content on the homepage based on if the customer is logged in or guest user.

  What should a developer implement to achieve this requirement?

  A. Write specific custom code in the Content Asset for a customer that is a registered, versus unregistered, user.
  B. Set the Content Slot configuration so it is based on the system customer group registered, versus unregistered.
  C. Set the Content Asset configuration for a customer that is a registered, versus unregistered, user.
  D. Add specific custom messages in Page Designer for a customer that is a registered, versus unregistered, user.
  B. Set the Content Slot configuration so it is based on the system customer group registered, versus unregistered.

  ---

  explanation: To display different content on the homepage based on whether the customer is logged in (registered) or is a guest (unregistered), the recommended approach is to use Content Slots configured for different customer groups. Salesforce B2C Commerce Cloud allows the configuration of Content Slots to display specific content based on various criteria, including customer groups. By setting up these slots to differentiate between registered and unregistered users, the site can dynamically display tailored content to users based on their logged-in status. This method leverages the platform's built-in capabilities for personalizing user experience without the need for extensive custom coding.
