Salesforce Updated Comm-Dev-101 Exam Questions and Answers by alys

American Express is acredit-card type used under the existingCREDIT_CARDpayment method, rather than a new payment processor or Site Preference. Therefore, the appropriate Business Manager action is to manage the supported Credit/Debit Cards associated with the credit-card payment method.

Salesforce documents that merchants manage payment methods underMerchant Tools > Site Ordering > Payment Methodsand that the Credit/Debit Cards page manages card types specifically in the context of the defaultCREDIT_CARDpayment method.

A payment processor represents the integration that processes transactions; American Express itself is not created as a payment processor simply because that card network should be accepted. Likewise, Site Preferences are not the mechanism used to enable supported card brands.

The underlying payment processor must, of course, support American Express transactions, but storefront card eligibility is configured through the credit/debit card configuration associated with the credit-card payment method. Card configuration can additionally restrict cards according to countries, currencies, customer groups, or payment ranges.

Logger.getLogger( " contact " )returns a logger associated with the custom categorycontact. Invoking.debug()on that logger writes the message at DEBUG severity under the specified category, assuming the corresponding category configuration permits DEBUG logging.

Salesforce ' sdw.system.LoggerAPI documents the one-argumentgetLogger(String)method as returning the logger for the supplied category. It also exposes DEBUG, INFO, WARN, ERROR, and other severity operations on the resulting logging object.

Option B uses the static root-style debug call and therefore does not explicitly bind the entry to the requested custom category. Option A is invalid becauseLogger.customLogger()is not a supported Script API method.

Category-based logging is useful for service integrations because Business Manager administrators can selectively increase diagnostic verbosity for a specific subsystem such ascontactwithout globally enabling excessive DEBUG output. Category rules can also be hierarchical, allowing narrower categories such ascontact.submitorcontact.response.

For a client-side AJAX endpoint whose response will be consumed by JavaScript,res.json()is the standard SFRA response method. It serializes the supplied data into a JSON response, allowing the client-side callback to update only the necessary part of the existing page without performing full server-side page rendering.

Salesforce ' s SFRA documentation explicitly states thatres.json(data)outputs a JSON object and ishelpful for creating AJAX service endpoints executed from client-side scripts. In contrast,res.render(templateName, data)renders an ISML template and produces markup intended for page or fragment rendering.

res.print()is a low-level text-output operation and does not provide the structured response contract that JSON gives client-side application logic.

An AJAX controller commonly returns information such as success status, validation errors, updated totals, URLs, messages, or calculated values as JSON. JavaScript then selectively updates the DOM based on those fields, preserving the rest of the page.

SFRA uses thePage-Showendpoint to render a content asset as a full storefront page. The endpoint accepts the query-string parametercid, which identifies the content asset to display. Consequently, the content-link expression must generate the equivalent of:

Page-Show?cid=about-us

and option A provides the correct syntax.

Salesforce ' s current SFRAPage.jsdocumentation identifiesPage-Showas the endpoint that renders a content asset in a full storefront page and explicitly documentscidas the content asset ID parameter. Salesforce also documents special content-link functions for links embedded inside content assets, allowing merchant-managed rich content to reference storefront resources without hard-coding complete URLs.

Content-ShowandContent-Pageare not the SFRA full-page content endpoints shown in these choices. Additionally, B does not passcidas the required parameter name.

Using the URL generation function rather than a literal storefront URL preserves correct host, locale, URL-rule, and deployment behavior.
