NEW QUESTION # 11
An Adobe Commerce developer wants to create a sticky widget.
How would the widget be initialized using the data-mage-init attribute?

Answer: C

Explanation:
Explanation
Option B is the correct way to initialize a widget using the data-mage-init attribute. The attribute value should be a JSON object with the widget name as the key and the widget options as the value. Option A is incorrect because it uses a string instead of an object for the attribute value. Option C is incorrect because it uses a colon instead of a comma to separate the widget name and the options.

NEW QUESTION # 12
An Adobe Commerce developer wants to create a new theme Vendor_Orange which extends from MagentoMuma. Which file is responsible for specifying the parent theme?

A. theme.xml
B. view.xml
C. registration.php

Answer: A

Explanation:
Explanation
The theme.xml file is responsible for specifying the parent theme of a custom theme. The file should contain the <parent> element with the value of the parent theme's directory, such as
<parent>MagentoMuma</parent>. The view.xml file is used to configure the theme's images, fonts, and layout. The registration.php file is used to register the theme in the system. References: [Create a theme],
[theme.xml]

NEW QUESTION # 13
An Adobe Commerce Developer is adding a new page layout to the theme directory within a custom theme.
Which file needs to be created to register the new page layout?

A. app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layouts.xnil
B. app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layout/layouts.xml
C. app/design/frontend/<VendorName>/<ThemeName>/layouts. xml

Answer: B

Explanation:
Explanation
To register a new page layout in a custom theme, the developer needs to create a layouts.xml file in the app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layout directory. The layouts.xml file should contain the <layout> element with the id, label, and file attributes. The id attribute is used to reference the layout in other layout files, the label attribute is used to display the layout name in the admin panel, and the file attribute is used to specify the path to the layout file relative to the web directory of the theme. The app/design/frontend/<VendorName>/<ThemeName>/layouts.xml and app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layouts.xml files are not valid and will not work. References: [Create a new page layout], [layouts.xml]

NEW QUESTION # 14
An Adobe Commerce developer wants to remove the default Wishlist and Compare Products blocks on a category page with layered navigation Where would this modification be placed, assuming the developer only wants to make this change?

A. app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/layout/override/catalog_category_view_
B. app/design/frontend/Vendor/Theme/Magento_Catalog/layout/catalog_category_view.xml
C. app/design/frontend/Vendor/Theme/Magento_Layered.Navigation/layout/catalog_category_view_type_lay

Answer: C

Explanation:
Explanation
To remove the default Wishlist and Compare Products blocks on a category page with layered navigation, the developer should place the modification in the app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/layout/catalog_category_view_type_layered.x file. This file is specific to the category pages with layered navigation and will override the default layout file from the Magento_LayeredNavigation module. The modification should use the <referenceBlock> tag with the name attribute specifying the name of the block and the remove attribute set to true. For example:
<referenceBlock name="catalog.compare.sidebar" remove="true"/> <referenceBlock name="wishlist_sidebar" remove="true"/> The app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/layout/override/catalog_category_view_type_ file is not valid and will not work, as it is not a valid override path. The app/design/frontend/Vendor/Theme/Magento_Catalog/layout/catalog_category_view.xml file is not specific to the category pages with layered navigation and will affect all category pages. References: [Layout override],

NEW QUESTION # 15
Which Ul component property is used for cross tracking property changes?

A. exports
B. links
C. listens

Answer: C

Explanation:
Explanation
The listens property is used for cross tracking property changes in the UI component. The listens property defines the dependencies between the properties of different UI components. It allows one UI component to listen to the changes of another UI component's property and react accordingly. For example, the listens property can be used to update the value of a text field based on the selection of a dropdown menu

NEW QUESTION # 16
An Adobe Commerce developer wants to override the template assigned to a block named existing, product, block. This relationship is defined in the catalog_product_view. xml layout in the Magento_Catalog module.
They cannot simply override the file in their theme, as this change is part of a feature that is being released to the marketplace as a module called "Orange_CustomProduct".
The developer has already created the desired template at app/code/Orange/CustomProduct/view/f rontend/templates/custom-product-block.phtml.
What can they add to app/code/Orange/CustomProduct/view/f rontend/layout/catalog_product_view. xml in their module to accomplish this?

Answer: D

Explanation:
Explanation
To override the template assigned to a block in a module, the developer needs to use the <referenceBlock> layout instruction with the name attribute specifying the name of the block and the template attribute specifying the path to the new template file. In this case, the code would be:
<referenceBlock name="existing.product.block"
template="Orange_CustomProduct::custom-product-block.phtml"/>
Option A is not valid because it uses <block> instead of <referenceBlock>, which would create a new block instead of referencing an existing one. Option C is not valid because it uses <argument> instead of
<template>, which would not change the template of the block. Option D is not valid because it uses an incorrect syntax for the template attribute, which should use two colons instead of a slash. References: [Layout instructions], [Override templates and layout files]

NEW QUESTION # 17
Adobe commerce fronted developer needs to speed up the cloud environment deployment process with predefined theme languages for reducing the number of unnecessary themes files.
Which place developer should add language codes?

A. relationships property in .magento.app.yaral file
B. SCD_matrix deploy variable in .magento.env.yaml file
C. scopes section in config.php file

Answer: B

Explanation:
Explanation
The SCD_matrix deploy variable in the .magento.env.yaml file is used to speed up the cloud environment deployment process by specifying the theme languages for each theme. This reduces the number of unnecessary theme files that are generated during the static content deployment. The developer can add the language codes for each theme in the following format:
SCD_MATRIX: <theme>: <languages>
For example, to specify English and French languages for the Vendor/Orange theme, the developer can use:
SCD_MATRIX: Vendor/Orange: en_US,fr_FR
The other two options are incorrect because they are not related to the theme languages or the static content deployment. The relationships property in the .magento.app.yaml file is used to define how services are connected to the application. The scopes section in the config.php file is used to specify the configuration scope of each module. References: Adobe Commerce Developer Documentation, Adobe Inc.

NEW QUESTION # 18
An Adobe Commerce developer wants to add a custom widget that extends the default Calendar Widget. What would the contents of this file look like?

Answer: C

Explanation:
Explanation
To add a custom widget that extends the default Calendar Widget, the contents of the file would look like option B. This is because option B follows the correct syntax and structure for defining a jQuery widget in Magento. The code does the following steps:
Defines a module with the name "Vendor_Module/js/calendar-widget" that depends on the "jquery/ui" and "Magento_Ui/js/lib/knockout/bindings/datepicker" modules.
Returns a function that creates a new widget with the name "vendor.calendarWidget" that extends the base calendar widget class.
Overrides the init function of the base calendar widget class to add custom logic or functionality to the widget.
Option A is not correct because it does not use the correct syntax for defining a jQuery widget. It uses a script tag instead of a define function, which is not valid for creating a module. It also uses an incorrect name for the widget, which should use a dot instead of a slash. Option C is not correct because it does not use the correct syntax for extending a widget. It uses an extend function instead of a widget function, which is not valid for creating a new widget. It also does not return anything from the module, which will cause an error.
References: [jQuery widgets], [Calendar Widget]

NEW QUESTION # 19
An Adobe Commerce developer is working on a custom knockout Ul component and they need to add the text Happy Birthday. to be translated inside an .html template.
How would the developer add the text?

A.
B. <span data-bind=Mil8n: 'Happy Birthday.'"></span>
C. <span data-bind="il8n: Happy Birthday."></span>

Answer: C

Explanation:
Explanation
To add the text Happy Birthday. to be translated inside an .html template, the developer should use the i18n binding. This binding allows the developer to specify the text as a string literal and translate it using the Magento translation mechanism. For example:
<span data-bind="i18n: 'Happy Birthday.'"></span>
This will render the text as it is, or translate it if a translation file is available for the current locale. The i18n binding can also accept variables or expressions as arguments. For example:
<span data-bind="i18n: name + ' Happy Birthday.'"></span>
This will render the text with the value of name variable, or translate it if a translation file is available for the current locale. The Mil8n and il8n bindings are not valid and will not work, as they are misspelled and do not match the knockout binding syntax. References: [Knockout bindings], [i18n binding]

NEW QUESTION # 20
An Adobe Commerce developer wants to apply a knockout binding to a <div> to run a function, onClick(), when it's clicked. Which two solutions would the developer use to achieve this? (Choose two.)

A. <div data-bind="click: onClick()"><x/div>
B. <div> </div>
C. <div click=,,onClick"X/div>
D. <div data-bind="click: onClick"></div>

Answer: A,D

Explanation:
Explanation
To apply a knockout binding to a <div> to run a function, onClick(), when it's clicked, the developer can use either of the following solutions:
A: <div data-bind="click: onClick()"></div>: This solution will use the click binding to execute the onClick() function as an expression when the <div> is clicked. The function will be called with the current binding context as the first parameter and the event object as the second parameter.
C: <div data-bind="click: onClick"></div>: This solution will use the click binding to execute the onClick function as a reference when the <div> is clicked. The function will be called with the current binding context as the first parameter and the event object as the second parameter.
The following solutions are not valid and will not work:
B: <div></div>: This solution will use the virtual element syntax to apply the click binding, but it will pass a string literal instead of a function expression or reference.
This will cause an error, as the click binding expects a function value.
D: <div click="onClick"></div>: This solution will use a custom attribute instead of a data-bind attribute to apply the click binding. This is not supported by knockout and will not have any effect.

NEW QUESTION # 21
An Adobe Commerce developer needs to display a URL in the template. How would the variable $ur1be securely output in the template?

A. <?php echo $escaper->escapeHtml($url) ?>
B. <?php echo $escaper->escapeUrl($url) ?>
C. <?php echo $escaper->escapeLink($url) ?>

Answer: B

Explanation:
Explanation
To display a URL in a template securely, the developer should use the escapeUrl method of the escaper object.
This method will encode any special characters in the URL that can be used for XSS attacks, such as &, <, >,
", ', etc. For example:
<?php echo $escaper->escapeUrl($url) ?>
The following methods are not suitable for displaying URLs and should not be used:
<?php echo $escaper->escapeLink($url) ?>: This method is used for escaping link attributes, not URLs.
It will encode any characters that are valid in URLs but invalid in HTML attributes, such as spaces, quotes, etc. For example:
<?php echo $escaper->escapeLink('https://example.com/?q=hello world') ?> // Output:
https://example.com/?q=hello%20world
<?php echo $escaper->escapeHtml($url) ?>: This method is used for escaping HTML content, not URLs. It will encode any characters that are valid in URLs but invalid in HTML content, such as &, <,
>, etc. For example:
<?php echo $escaper->escapeHtml('https://example.com/?q=<script>alert("XSS")</script>') ?> // Output:
https://example.com/?q=<script>alert("XSS")</script>

NEW QUESTION # 22
An Adobe Commerce developer is customizing buttons for a custom theme that inherits Magento/blank theme and needs to override the default values. Where would the default values for the buttons be located?

A. lib/web/css/source/lib/_buttons.less
B. lib/web/css/source/lib/_button.less
C. lib/web/less/source/lib/_buttons.less

Answer: A

Explanation:
Explanation
To find the default values for the buttons, the developer needs to look at the lib/web/css/source/lib/_buttons.less file. This file contains various variables, mixins, and styles for defining and customizing buttons. The developer can override these values in their custom theme by using the
.lib-button() mixin or by creating their own mixins or classes. For example:
lib-button( @_button-selector, @_button-type, @_button-shape, @_button-color, @_button-background,
@_button-border, @_button-text-transform, @_button-box-shadow, @_button-hover-color,
@_button-hover-background, @_button-hover-border, @_button-hover-box-shadow ); The lib/web/less/source/lib/_buttons.less and lib/web/css/source/lib/_button.less files are not valid and do not exist. References: [Buttons], [Magento UI library]

NEW QUESTION # 23
An Adobe Commerce developer needs to pass JSON data to a JavaScript component while keeping XSS prevention strategies in mind.
Which two options would the developer use? (Choose two.)

Answer: A,B

Explanation:
Explanation
To pass JSON data to a JavaScript component while keeping XSS prevention strategies in mind, the developer should use the following options:
Option A: Use the x-magento-init script tag with the data-mage-init attribute and the JSON.parse function to initialize the component with the JSON data. This option is secure because it does not use any HTML tags or attributes that can be exploited by XSS attacks.
Option C: Use the text/x-magento-init script tag with the type attribute and the JSON.parse function to initialize the component with the JSON data. This option is secure because it does not use any HTML tags or attributes that can be exploited by XSS attacks.
The following options are not secure and should not be used:
Option B: Use the script tag with the type attribute and the escapeHtmlAttr function to initialize the component with the JSON data. This option is not secure because it uses the escapeHtmlAttr function, which is meant for escaping HTML attributes, not JSON data. This function can introduce double quotes in the JSON data, which can break the JSON syntax and cause errors.
Option D: Use the script tag with the type attribute and the escapeJsQuote function to initialize the component with the JSON data. This option is not secure because it uses the escapeJsQuote function, which is meant for escaping JavaScript strings, not JSON data. This function can introduce backslashes in the JSON data, which can break the JSON syntax and cause errors.

NEW QUESTION # 24
An Adobe Commerce developer is using a view model within an existing block:

What are two ways to access the view model class in the template? (Choose two.)

A. $block->getViewHodel()
B. $block->getData('view_model')
C. $block->getData('viewModel)
D. $block->viewModel()

Answer: B,C

Explanation:
Explanation
To access a view model within an existing block, the developer can use either of the following ways:
$block->getData('view_model'): This method will return the view model object that is assigned to the argument name "view_model" in the layout XML file. For example:
<referenceBlock name="blog_posts_list"> <arguments> <argument name="view_model" xsi:type="object">ExampleObjectModel/ExampleObjectModel</argument> </arguments> </referenceBlock> In the template file, the developer can access the view model object by using:
$block->getData('view_model')
$block->getData('viewModel'): This method will return the view model object that is assigned to the argument name "viewModel" in the layout XML file. For example:
<referenceBlock name="blog_posts_list"> <arguments> <argument name="viewModel" xsi:type="object">ExampleObjectModel/ExampleObjectModel</argument> </arguments> </referenceBlock> In the template file, the developer can access the view model object by using:
$block->getData('viewModel')
The following methods are not valid and will not work:
$block->viewModel(): This method does not exist and will cause an error.
$block->getViewHodel(): This method is misspelled and will cause an error.

NEW QUESTION # 25
The merchant needs to create a new website, and is need modify a template the third party vendor's, because the customer is different. The file is found in a module here: app/code/Vendor/Module Keep it simple in your mind!

A. Create another layout for the new website and configure new file.phtml.
app/code/Vendor/Module/view/frontend/templates/file.phtml
B. Create a new module for extends layout.xml and include new file.phtml.
app/code/Vendor/Module_Two/view/frontend/templates/file.phtml
C. Create a new theme, define a new website and customize in app/design.
app/design/frontend/Custom/Theme/Vendor_Module/templates/file.phtml

Answer: C

Explanation:
Explanation
The best way to customize a template file from a third-party module is to create a new theme that inherits from the parent theme and override the template file in the app/design/frontend/Custom/Theme/Vendor_Module/templates directory. This way, the customization is isolated from the original module and can be applied to a specific website or store view. Creating another layout file or a new module would not be as simple or flexible as creating a new theme. References: Frontend development guide, [Create a theme], [Theme inheritance]

NEW QUESTION # 26
An Adobe Commerce developer needs to alias URLs and third party libraries inside a require js-config.js file.
Which configuration would the developer use?

Answer: B

Explanation:
Explanation
To alias URLs and third party libraries inside a requirejs-config.js file, the developer should use the paths configuration option. This option allows the developer to map module names to URLs or paths relative to the baseUrl. For example:
var config = { paths: { 'jquery': 'https://code.jquery.com/jquery-3.6.0.min', 'custom':
'Vendor_Module/js/custom' } };
This will map the module name 'jquery' to the URL of the jQuery library and the module name 'custom' to the path of the custom module. The developer can then use these module names in other modules or files without specifying the full URL or path.
Option A is not correct because it uses the shim configuration option, which is used to define dependencies and exports for non-AMD modules, not to alias URLs or paths. Option C is not correct because it uses the map configuration option, which is used to map module names to other module names for specific contexts, not to alias URLs or paths. References: [RequireJS configuration], [RequireJS paths]

NEW QUESTION # 27
An Adobe Commerce developer has been asked to move a block called country from the container sidebar to the container content, the block has to be the last child on the content container.
Which layout instruction would be used to move the block?

A. <moveelement = "country"destination="content" after="-"/>
B. <move element="country" destination="content" after="last-child"/>
C. <move element="country-element"destination="content-element"/>

Answer: A

Explanation:
Explanation
To move a block from one container to another, the developer needs to use the <move> layout instruction with the element attribute specifying the name of the block and the destination attribute specifying the name of the container. The after attribute can be used to position the block relative to other blocks in the same container.
The value "-" means that the block will be placed after all other blocks, i.e., as the last child. The value
"last-child" is not valid for the after attribute and will not work. The element and destination attributes should use the names of the blocks and containers, not their aliases or classes. References: [Layout instructions],
[Move an element]

NEW QUESTION # 28
An Adobe Commerce developer is extending a theme from Magento\blank and wants to override parent styles.
Which file does the developer need to change to override the parent theme styles?

A. web/css/source/_extends.less
B. web/css/source/_theme. less
C. web/css/source/_extend.less

Answer: C

Explanation:
Explanation
To override the parent theme styles, the developer needs to change the web/css/source/_extend.less file in the child theme. This file is used to import and extend the parent theme styles without modifying the original files.
The developer can use the @import directive to import the parent theme styles and then use the .lib-css() mixin to override the CSS properties. For example:
@import 'source/_extend.less'; // Import parent theme styles .lib-css(color, red); // Override color property The web/css/source/_extends.less and web/css/source/_theme.less files are not valid and will not work, as they do not follow the theme structure or the naming convention. References: [Theme inheritance], [Extend parent theme styles]

NEW QUESTION # 29
An Adobe Commerce developer is building a theme Vendor/Orange and needs to customize the header of email templates. Where in the theme does the developer need to place the new template for this customization?

A. /Magento_Theme/html/header.html
B. /Magento_Email/templates/override/html/header.html
C. /Magento_Email/email/header.html

Answer: C

Explanation:
Explanation
To customize the header of email templates, the developer needs to place the new template in the
/Magento_Email/email/header.html path of the theme. This will override the default header template from the Magento_Email module. The /Magento_Email/templates/override/html/header.html path is not valid and will not work. The /Magento_Theme/html/header.html path is used for customizing the header of web pages, not emails. References: [Customize email templates], [Email templates overview]

NEW QUESTION # 30
An Adobe Commerce developer is trying to remove a block using the <remove name="test.block'/> tag in a layout XML file but it shows an error and doesn't work.
Which tag would be applied to fix the error?

A. Use <remove name="Custom_Module:test.block"/>
B. US6 <referenceBlock name="test.block" remove="true"/>
C. Use<referenceBlock name="test.block" delete="true'7>

Answer: B

Explanation:
Explanation
To remove a block using layout XML, the developer should use the <referenceBlock> tag with the name attribute specifying the name of the block and the remove attribute set to true. For example:
<referenceBlock name="test.block" remove="true"/>
This will remove the block from the layout and prevent it from rendering. The <remove> tag is not valid and will cause an error. The name attribute should not include the module name, as it is not part of the block name.
The delete attribute is not valid and will not work. References: [Layout instructions], [Remove an element]
