Logger.warn('The current product is {0} with name {1}').context (myProduct.getID(), myProduct.getName());

A NewsletterSubscription custom object exists that has a key attribute named email of type String and the following script code.

var CustomObject = dw.object.CustomObjectMgr.createCustomObject('NewsletterSubscription', newsletterForm.email.value);

However, the NewsletterSubscription custom object is not persisted.

What is a possible reason?

The code shown is the wrong syntax. The correct syntax is:

var CustomObject = dw.object.CustomObjectMgr.createCustomObject('NewsletterSubscription', 'email', newsletterForm.email.value);

The code shown needs to be wrapped in a try-catch block

The code shown is the wrong syntax. The correct syntax is:

var CustomObject = dw.object.CustomObjectMgr.createCustomObject(newsletterForm.email.value, 'NewsletterSubscription');

The code shown needs to be wrapped in a transaction.

A retailer notices that the Account Addresses page is showing the wrong shopper's address.
Which tool should the developer start with to identify the issue?

Pipeline Profiler

Code Profiler

Reports and Dashboards module

Storefront Toolkit

A developer is implementing new Page Designer content on a merchant's Storefront and adds the line below to the setupContentSearch function in the searchHelpers.js file.

apiContentSearchModel.setFilteredByFolder(false);

What does this achieve?

Filters Page Designer search results into folders

Prevents Page Designer pages from being searchable

Allows Page Designer pages and components to be searchable

Allows filtering Page Designer pages by folder

Consider the following information:

A merchant has this three-tier category structure setup in the Storefront catalog.
- New Arrivals > Women > Clothing
The category named Clothing has all the clothing items for Women and is merchandised.
A Search Refinement named Newness is correctly configured for the Clothing category.

When a merchandiser views the Clothing category, the Search Refinement appears and works as expected. However, the merchandiser does not see the Search Refinement when searching for Clothing via the Storefront search.
What is the reason?

The Search Refinement definition is not set up for the New Arrivals category

There are conflicting Search Refinement definitions for Clothing and one of its parent categories

The Search Refinement definition is not set up for the Women category

The Search Refinement definition is not set up for the Root category

Given the requirement to add caching to an existing page while adhering to SFRA best practices, which code snippet should be used?

server.get('Show', cache.applyDefaultCache, function (req, res, next) { //code });

server.get('Show', function (req, res, next) { //code
}).applyDefaultCache();

Given the SFRA Controller below:

01 var server = require('server');

02 var cache = require('*/cartridge/scripts/middleware/cache');

04 server.get('Show', cache.applyDefaultCache, function (req, res, next) {

05 viewData = {name: 'my string'};

06 res.render('/pages/mypage', viewDate);

07 next();

08 });

10 module.exports = server.exports();

Why would a JavaScript debugger, that is stopped at line 06, fail to show the viewData variable in the inspection tool?

viewData is declared but not assigned

viewData is assigned but not declared

viewData is a B2C Script reserved name

cache.applyDefaultCache is not a valid middleware

Which three configurations does a developer need to ensure to have a new product visible in the Storefront? (Choose three.)

The Storefront catalog that contains the product is assigned to a site

The product has a price

The product has a master product

The product is online and searchable

The search index is built

A developer needs to share their sandbox data with a colleague working on the same realm.

What is the best practice to share data between two environments?

Perform a site export and a local site import

Perform a data replication from one sandbox to the other

Perform a site export using the global export directory

Perform a site export using the remote archive

A developer is given a task to implement a new Page Designer layout component that doesn't accept certain asset components.
How should the developer achieve the above task?

Add layout_type_exclusion in the other asset components json configuration

Add component_type_inclusion in the layout json configuration

Add layout_type_inclusion in the target components json configurations

Add component_type_exclusions in the layout json configuration

Given a file in a plug-in cartridge with the following code:

'use strict';

var base = module.superModule;

function applyCustomCache(req, res, next) {

res.cachePeriod=6; //eslint-disable-line no-param-reassign

res.cachePeriodUnit='hours'; //eslint-disable-line no-param-reassign

next();

}

module.exports = base;

module.exports.applyCustomCache = applyCustomCache;

What does this code extend?

A middleware script

A controller

A decorator

A model

Given the customer basket described below:

A customer has an existing basket that consists of multiple items.
One of the items is identified as a gift item by an attribute at the product line item.

The developer needs to write custom code to fetch the customer basket and then modify the basket based upon the items in the cart. If the basket contains any gift items, modify the basket and create a separate shipment for the gift item.

Four hooks are required to make the modification, beginning with modifyGETResponse and ending with validateBasket.

dw.ocapi.shop.basket.modifyGETResponse
-- missing hook --
-- missing hook --
dw.ocapi.shop.basket.validateBasket

What are the two missing hooks on the middle? (Choose two.)

dw.ocapi.shop.basket.shipment.afterDELETE

dw.ocapi.shop.basket.shipment.beforePOST

dw.ocapi.shop.basket.shipment.beforePATCH

dw.ocapi.shop.basket.shipment.beforeDELETE

A merchant reports that a particular landing page loads slowly. As a result, there is a significantly higher visitor departure rate in the analytics that appears to correlate with this. They anticipate this will impact revenues and want to resolve as soon as possible.

In order to diagnose and remedy this, the merchant asks their developer to investigate caching settings on the page in an attempt to determine the root cause.

How can the developer quickly inspect the page components to understand the caching?

Open the request logs to inspect the caching information

Utilize the debugger to inspect the caching information

Use the Storefront Toolkit cache info tool to inspect page components

Inspect the caching properties of the page component in an IDE

A client sells its product in single-brand stores as well as in multi-brand stores. When shown in the store locator list, the client wants the single-brand stores to have a particular background color to highlight them.

Which Business Manager action should be completed to allow the developer to apply different styling to the single-brand stores?

Add a Boolean custom attribute to the Store system object

Configure the existing Store custom object type definition

Adjust the relevant Site Preference in the Stores group

Create a new SingleBrandStore custom object configuration

Given a template rendered by a controller with caching and a remote include without caching, which situation applies?

The remote include portion is not cached, but the rest of the page is cached

Both the remote include portion and the rest of the page are cached

The page is cached only for returning customers because of the remote include

The page is not cached because the remote include introduces an uncached portion

A client that sells to multiple countries in Europe needs to disable Apple Pay for Denmark.

Which Business Manager module is used to achieve this requirement?

Locale Payments

Apple Pay

Payment Processors

Payment Methods

A developer uses the call() instance method of dw.svc.Service to invoke a web service and implemented the callback methods defined by the dw.svc.ServiceCallback class.

Which callback method is required only when invoking a SOAP service?

initServiceClient

parseResponse

mockCall

createRequest

The following code performs poorly in the storefront.

var productHits = dw.catalog.ProductSearchModel.getProductSearchHits().getRepresentedProducts();

var results = null;

for (var I = 0; I < productHits.length; i++) {

var variations = null;

if (productHits[i].isMaster()) {

variations = productHits[i].getVariationModel().getVariants();

for (var j=0; variations.length; i++) {

if (variations[j].getAvailabilityModel().isOrderable()) {

results.add(variations[j]);

}

} else {

results.add(productHits[i];

}

Considering best practices, what is the main problem with this code?

The code performs post-query processing in an inefficient manner. The nested for-loops should be changed to more efficient code.

The code uses ProductSearchModel, which performs a database search.

The code invokes dw.catalog.ProductSearchModel directly. It is more efficient to use the following code and then invoke the method.

var ProductSearchModel = require('dw.catalog.ProductSearchModel');

The code performs post-query processing, which is inefficient and should be avoided

Given the requirements:

To integrate with an external web service using HTTP requests.
To create a service for this purpose with the Service framework using the LocalServiceRegistry class.
To test the service before the external service provider makes the API available.

Which solution allows the developer to satisfy the requirements?

Create a service and a Sitepreference that induce the service to respond with a mock response using a conditional.

Create a service and implement the mockFull callback and set the service mode to mock.

Create a service and implement the mockFull callback and a sitepreference to enable or disable the mock response.

Create two services, one mock and the real one, and a Sitepreference that enable the mock or the real one.

A merchant has a new requirement to accept American Express credit cards on its Storefront. A credit card payment method already exists.

Which step must a developer take in Business Manager to achieve this?

Add American Express as a Payment Preference in Site Preferences

Add American Express into the Order settings in Site Preferences

In Payment Methods, enable American Express as a credit card type

Payment Processor, create American Express as a payment type

A developer wants to embed a link to a content page from within the body of another content asset.

The target content asset ID is: about-us

Which option represents the correct format to use?

$url('Content-Page', 'cid', 'about-us')$

$url('Content-Show', 'about-us')$

$url('Page-Show', 'about-us')$

$url('Page-Show', 'cid', 'about-us')$

The Home-Show route uses this middleware chain:
server.get('Show', consentTracking.consent, cache.applyDefaultCache, function (req, res, next) {

//based code here

});
The developer added Home.js in another cartridge, which is before the original cartridge in the cartridge path, to extend that route but it does not have the middleware chain:

server.append('Show', function (req, res, next) {
//custom code here
});

Assuming the code is correct on both functions, what is the expected result?

The custom code executes and then the base code executes

A RunTime error is thrown, "Error: Params do not match route"

The base code executes, but the custom code is ignored because the signature lines do not match

The base code executes and then the custom code executes

Business Manager has the configuration:

Active Log category is "root"
Log level of INFO

The code below executes.

var log = Logger.getLogger("products", "export"); log.info("This is important information");

Using this information, what is the beginning of the filename in which the log will be written?

Custom-products

Products

Custom-export

Info-export

A developer adds a file named ControllerA.js in the cartridge named app_custom_new project.

The design calls for this new file to extend functionality from ControllerA.js in app_custom_brand_project.

The app_custom_brand_project and app_storefront_base cartridges include additional functionality that is required.

Which cartridge path meets the project requirements?

app_custom_new_project:app_storefront_base:app_custom_brand_project

app_custom_new_project:app_custom_brand_project:app_storefront_base

app_storefront_base:app_custom_brand_project:app_custom_new_project

app_custom_brand_project:app_custom_new_project:app_storefront_base

A developer needs to display a products list of their "Women Dresses" category in a new web application, independent of their main B2C Commerce site. This custom listing page needs to be styled differently from the existing one, as per marketing requirements.

Which B2C Commerce tool should the developer use to collect the necessary information?

The existing category’s endpoint to perform a REST call

The ProductSearch resource of the Shop OCAPI

The iframe of the existing category page

The Search-Show Controller URL to perform a web crawl

An instance has custom logging enabled. The log reaches the file size limit.

What happens in this situation?

The current log file is archived and a new log file is created

The log file is deleted and a new log file is created

Logging is suspended for the day

The log file rolls over and the oldest log messages are overwritten

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?

Use a client-side cookie to store the information for the session duration

Use the Session class, and its additional class references and attributes, in the B2C Commerce API

Use a non-replicable Custom Object to store the information temporarily

Use an SFRA controller. Because it runs server-side, the state is automatically maintained

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 two.)

Implement template decorators paired with replace tags

Embed partial files using ISML expressions

Require and render templates with tags

Use local template includes

When exporting a site catalog from an external system, which file format or formats should a developer use so it can be imported into a B2C Commerce site?

XML only

CSV only

XML and JSON

JSON only

Refer to the screen shot below:

Given a site called RefArch that has the settings shown, what must be done for RefArch to use the same customer list as RefArchGlobal?

Select RefArchGlobal in the dropdown for Customer List

Import the RefArchGlobal customer list into the RefArch site

Enable "Customer List Sharing" in Site Preferences

Enable "Customer List Sharing" in Global Preferences

A client uses tax tables in Business Manager to calculate tax. They recently started shipping to a new country, Italy, and the tax is not being calculated correctly on the Storefront.

What is the likely problem?

Tax Region is configured wrong

Tax Country is missing

Tax Jurisdiction is missing

Tax Locale is configured wrong

Given a B2C Commerce client with these specifics:

Sells in two different countries: US and IN
Uses only the English language

A developer has a requirement to add a new field to the IN registration form that must not appear in the US one.

Which path should be created to accomplish this requirement?

cartridge/forms/profile_en_IN.xml

cartridge/forms/profile_in.xml

cartridge/forms/in/profile.xml

cartridge/forms/en_IN/profile.xml

A Newsletter controller contains the following route:

server.post('Subscribe', function (req, res, next) {

var newsletterForm = server.forms.getForm('newsletter');

var CustomObjMgr = require('dw/object/CustomObjectMgr');

if (newsletterForm.valid) {

try {

var CustomObject = CustomObjectMgr.createCustomObject('NewsletterSubscription', newsletterForm.email.value);

CustomObject.custom.firstName = newsletterForm.fname.value;

CustomObject.custom.lastName = newsletterForm.lname.value;

res.render('/newsletter/newslettersuccess');

} catch (e) {

// Catch error here

}

next();

});

Assuming the Custom Object metadata exists, why does this route fail to persist the data submitted in the form beyond the template render lifecycle?

Custom Objects can only be created by Job scripts

The Custom Object creation is not wrapped in a Transaction

The CustomObjectMgr variable should be declared outside of the route

The Subscribe route is missing the server.middleware.http middleware

A developer working on a multi-country site is asked to store country-specific data that drives the creation of a country selector.

Examples of the data stored are:

Pricebook to be used
Image URL for country flag

The data used in staging also applies in production, but only for this site.

Which approach should the developer take to implement these requirements?

Extend the Locale System Object to contain the custom data for each country

Create a replicable, site-specific Custom Object with the custom data for each country

Create a replicable, organization scope Custom Object with the custom data for each country

Create site-specific content assets to store the data for each country

A Storefront is designed so that multiple pages share a common header and footer layout.

Which ISML tag should a developer use on the templates for these pages to avoid code repetition in the most effective way?

Below is a form definition snippet from the newsletter.xml file.

<?xml version="1.0"?>

</form>

Which line of code creates a JSON object to contain the form data?

server.form.getForm('dwfrm_newsletter')

server.forms.getForm('newsletter')

server.form.getForm('newsletter')

server.forms.getForm('dwfrm_newsletter')

Which method is efficient and scalable because it uses the product search index rather than searching the database?

ProductAvailabilityModel.isOrderable()

ProductVariationModel.getVariants()

ProductIndexModel.getOrderableProductsOnly()

ProductSearchModel().getProductSearchHits()

A merchant has a requirement to render personalized content on a category page via a Content Slot that targets VIP high-spending customers during a specific promotional period.
