NEW QUESTION # 70
Which line of code should a developer add for custom category debug logging?
Answer: A
Explanation:
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.

Given the SFRA Controller below:
Why would a JavaScript debugger, that is stopped at line 06, fall to show the viewdata variable in the inspection tool?
Answer: D
NEW QUESTION # 72
A developer is writing a server side script that needs to maintain state across calls. The persistent information needed includes these items:
* The current customer
* Whether or not the customer is authenticated
* The privacy attributes (such as tracking consent or cookie policy)
Which technique should the developer use to maintain state in an efficient and scalable manner that follows best practice?
Answer: B
Explanation:
Server-side script variables do not persist between independent request executions. B2C Commerce therefore provides theSessionobject as the appropriate request-session mechanism for maintaining shopper-specific state across calls.
Salesforce specifically identifies the Session API as providing access to thecurrent customer, whether that customer isauthenticated, session custom attributes, andcustom privacy attributes. These capabilities map directly to every requirement in the question.
A client-side cookie is inappropriate for reproducing server-maintained authentication and customer state. It would also expose application-controlled values to client modification and duplicate information already securely managed by the Commerce session. An SFRA controller does not automatically preserve its own JavaScript variables across requests; each request executes within a separate script context.
Session data should nevertheless remain lightweight. Long-lived or business-critical information that must survive beyond the shopper ' s browser session belongs in persistent business objects rather than session attributes. Privacy attributes have specific lifecycle semantics and are particularly appropriate for tracking consent and related shopper preferences during the active session.
Study Guide reference:Application Development - Session API, shopper state, authentication state, privacy attributes, server-side JavaScript execution lifecycle, and scalable state management.
NEW QUESTION # 73
Given the file structure below, which ISML method call renders the customLandingPage template?
Answer: B
NEW QUESTION # 74
The developer needs to add custom category debug logging into the " contact " script, to ensure that a third- party service call responds as expected.
Assuming that the logging configurations for the contact category are correctly in place, which line of code should the developer add in the 06 placeholder to meet this requirement?
01varLogger=require( ' dw/system/Logger ' );
02varservice=dw.svc.LocalServiceRegistry.createService( ' contact.http.submit ' ,options);
03varserviceResponse=service.call(requestJSON);
04
05if(serviceResponse.ok) {
06// Insert logging code here
07}
Answer: B
Explanation:
Logger.getLogger( ' contact ' )creates or retrieves a logger associated with thecontactcategory. Calling.debug() on that logger writes the message at DEBUG severity, subject to the configured category and log-target rules.
B2C Commerce custom logging uses hierarchical category names patterned after log4j. Categories can be activated at particular severity levels inAdministration > Operations > Custom Log Settings. Salesforce explains that child categories inherit applicable settings from their parent categories unless they have more specific configuration.
Option B uses the generic staticLogger.debug()call and does not explicitly associate the statement with the required customcontactcategory. Option C refers to a nonexistentcustomLogger()API.
The category-specific approach is operationally superior when troubleshooting a third-party integration because administrators can selectively enable DEBUG logging forcontactwithout enabling extensive debugging across unrelated application code. Once the issue is diagnosed, that category ' s verbosity can be reduced again.
Study Guide reference:Application Development -dw.system.Logger, custom categories, DEBUG logging, Service Framework diagnostics, and hierarchical logging configuration.
