NEW QUESTION # 15
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. US6 <referenceBlock name="test.block" remove="true"/>
- B. Use<referenceBlock name="test.block" delete="true'7>
- C. Use <remove name="Custom_Module:test.block"/>
Answer: A
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]
NEW QUESTION # 16
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.

NEW QUESTION # 17
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/layout/layouts.xml
- B. app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layouts.xnil
- C. app/design/frontend/<VendorName>/<ThemeName>/layouts. xml
Answer: A
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 # 18
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. <move element="country-element"destination="content-element"/>
- B. <move element="country" destination="content" after="last-child"/>
- C. <moveelement = "country"destination="content" after="-"/>
Answer: C
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],

NEW QUESTION # 19
By creating a Custom_Module, an Adobe Commerce Developer has implemented a new Page Builder viewport for tablet devices but the viewport's tablet selector button is missing.
The button .svg has been properly added to the path: CustomJ^odule/web/css/images/switcher/switcher-tablet
.svg. How the developer would implement the viewport button icon?
A)
By setting the node icon in the theme's etc/view.xml file for the respective viewport configuration data.
B)
By setting the node button-image in the theme's etc/view.xml file for the respective viewport configuration data.
C)By adding the node image in the theme's etc/viewport.xml file for the respective viewport configuration data.
D)
By adding the node image in the theme's etc/viewport.xml file for the respective viewport configuration data.
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Answer: C
Explanation:
Explanation
Option C is the correct way to implement the viewport button icon. The image node specifies the path to the
.svg file relative to the web/css directory of the module. Option A is incorrect because there is no icon node in the viewport configuration data. Option B is incorrect because there is no button-image node in the viewport configuration data. Option D is incorrect because the image node value should not include the web/css part of the path.https://api.flutter.dev/flutter/widgets/PageView-class.html
NEW QUESTION # 20
An Adobe Commerce developer needs to improve the time of first render of the pages. How would the developer achieve this?
- A. Enable CSS critical path
- B. Enable JavaScript minification
- C. Enable CSS file merging
- D. Use the quick static files deployment strategy
Answer: A
Explanation:
Explanation
CSS critical path is a feature that improves the time of first render of the pages by inlining the CSS rules that are required to render the above-the-fold content of the page. This reduces the number of requests and bytes that need to be downloaded before the page is rendered. CSS critical path can be enabled in the Admin Panel by navigating to Stores > Configuration > Advanced > Developer > CSS Settings and setting Enable CSS Critical Path to Yes. References: Adobe Commerce Developer Documentation, Adobe Inc.
NEW QUESTION # 21
An Adobe Commerce developer needs to add CMS content above products on a specific category page via the Admin Panel. Where would the developer need to put the content in order to use Display Modes functionality and display it on the category?
- A. CMS Page
- B. CMS Block
- C. Widget
Answer: B
Explanation:
Explanation
CMS Blocks are the best option to add CMS content above products on a specific category page via the Admin Panel. CMS Blocks are reusable pieces of content that can be inserted into any page or layout using widgets or layout XML. CMS Blocks can be assigned to specific categories using the Display Settings tab in the category edit page. The developer can choose the Display Mode for the category, which determines how the CMS Block and the products are displayed on the category page. For example, the developer can choose Static block and products to show both the CMS Block and the products, or Static block only to show only the CMS Block and no products.

NEW QUESTION # 22
An Adobe Commerce developer wants to completely overwrite _module. less of Orange_Checkout module, in their theme. Where would the developer place the file?
- A. Custom/theme/Orange_Checkout/web/css/source/_module.less
- B. Custom/theme/web/css/source/Orange_Checkout/_module.less
- C. Custom/theme/Orange_Checkout/frontend/web/css/_module.less
Answer: A
Explanation:
Explanation
To completely overwrite _module.less of Orange_Checkout module in a custom theme, the developer should place the file in the Custom/theme/Orange_Checkout/web/css/source directory. This will override the default
_module.less file from the Orange_Checkout module and apply the custom styles to the theme. The Custom/theme/Orange_Checkout/frontend/web/css/_module.less and Custom/theme/web/css/source/Orange_Checkout/_module.less paths are not valid and will not work, as they do not follow the theme structure or the module naming convention. References: [Theme structure], [Module naming convention]
NEW QUESTION # 23
Which Ul component property is used for cross tracking property changes?
- A. links
- B. listens
- C. exports
Answer: B
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 # 24
An Adobe Commerce developer created a new CMS page and set the page title as "My Custom Page". The page must be accessible at the URL /custom_page.
Which CMS page configuration do they set to make the page accessible at /custom_page?
- A. Under "Page in Websites", they set the "URL" field as "custom.page".
- B. Under 'Content", they set the "Path" field as "custom_page".
- C. Under 'Search Engine Optimization", they set the "URL Key" field as "custom_page''.
Answer: C
Explanation:
Explanation
The URL Key field under the Search Engine Optimization section is used to specify the URL suffix for the CMS page. The developer can set it as "custom_page" to make the page accessible at /custom_page. The Path field under the Content section is used to specify the path to the template file that renders the CMS page content. The URL field under the Page in Websites section does not exist as a valid configuration option for CMS pages. References: [Adobe Commerce Developer Documentation], [Adobe Inc.]
NEW QUESTION # 25
An Adobe Commerce developer created a module called Orange_Customer. In customer information.
Where would the developer place this file?
- A. app/code/Orange/Customer/frontend/templates/customer-info.phtml
- B. app/code/OrangG/Custon>Gr/viGw/frontGnd/templates/customGr-info.phtml
- C. app/code/OrangG/customer/viev^/frontend/web/templates/customer-info.phtml
Answer: B
Explanation:
Explanation
To place a template file for a custom module, the developer should follow this path pattern:
app/code/<Vendor>/<Module>/view/<Area>/templates/<Template>
In this case, the vendor name is Orange, the module name is Customer, the area is frontend, and the template name is customer-info.phtml. Therefore, the correct path is:
app/code/Orange/Customer/view/frontend/templates/customer-info.phtml
The following paths are not correct and will not work:
app/code/Orange/customer/view/frontend/web/templates/customer-info.phtml: This path is incorrect because it uses web instead of templates, which is used for storing web assets like CSS, JS, and images, not template files.
app/code/Orange/Customer/frontend/templates/customer-info.phtml: This path is incorrect because it misses the view directory, which is required for separating frontend and backend templates.
NEW QUESTION # 26
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. SCD_matrix deploy variable in .magento.env.yaml file
- B. scopes section in config.php file
- C. relationships property in .magento.app.yaral file
Answer: A
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.

- A.
- B.
- C.
Answer: A
Explanation:
Explanation
Option C is the correct way to initialize a jQuery widget in a JavaScript file. The widget name should be prefixed with "mage" and the options should be passed as an object literal. Option A is incorrect because it uses a dot notation instead of a colon to separate the widget name and the options. Option B is incorrect because it uses a string instead of an object literal to pass the options.

- A. view.xml
- B. registration.php
- C. theme.xml
Answer: C
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],

NEW QUESTION # 30
An Adobe Commerce developer has found following code:
After compiling the .less file into a .ess file, what will be the results of the code above?
- A.
- B.
- C.
Answer: B
Explanation:
Explanation
After compiling the .less file into a .css file, the result of the code above will be option B. This is because the
.less file uses a mixin called .animation() that takes two parameters: the name of the animation and the duration. The mixin defines a set of vendor-prefixed properties for the animation and assigns them the values of the parameters. For example:
animation(@name; @duration) { -webkit-animation-name: @name; -webkit-animation-duration: @duration;
-moz-animation-name: @name; -moz-animation-duration: @duration; animation-name: @name; animation-duration: @duration; } When the mixin is called with the values "fade" and "2s", it will generate the following CSS code:
-webkit-animation-name: fade; -webkit-animation-duration: 2s; -moz-animation-name: fade;
-moz-animation-duration: 2s; animation-name: fade; animation-duration: 2s; Option A is not correct because it does not use the vendor prefixes for the animation properties. Option C is not correct because it uses the wrong values for the animation name and duration. References: [LESS Mixins],

NEW QUESTION # 31
An Adobe Commerce developer wants to override the following Layout XML file in the theme ExampleCorp/orange.
app/design/frontend/ExampleCorp/blank/Vendor_Module/layout/catalog_product_view.xml What path would the developer use inside the layout directory of the theme to override the file?
- A. /override/theme/ExampleCorp/blank/catalog_product_view.xml
- B. /override/ExampleCorp/blank/catalog_product_view.xml
- C. /catalog_product_view.xml
Answer: C
Explanation:
Explanation
To override a layout XML file from a parent theme, the developer just needs to place the modified file in the same path relative to the layout directory of the child theme. In this case, the file would be app/design/frontend/ExampleCorp/orange/Vendor_Module/layout/catalog_product_view.xml. The override directory is not used for overriding layout files, but for overriding templates and web assets. References:
[Layout instructions], [Override templates and layout files]
NEW QUESTION # 32
What is the difference between styles-l.less and styles-m.less ?
- A. styles-i.less is used to generate desktop-specific styles and stytes-m.less is used to generate only mobile-specific styles.
- B. styles-i.less is used to generate desktop-specific styles and stytes-m.less is used to generate basic and mobile-specific styles.
- C. styles-i.less is used to generate basic and mobile-specific styles and stytes-m.less is used to generate desktop-specific styles.
Answer: B
Explanation:
Explanation
The styles-l.less and styles-m.less files are two main LESS files that are used to generate CSS files for different devices and screen sizes. The styles-l.less file is used to generate styles-l.css, which contains desktop-specific styles that are applied only when the screen width is greater than 768px. The styles-m.less file is used to generate styles-m.css, which contains basic and mobile-specific styles that are applied for all devices and screen sizes. The other options are not correct and do not reflect the purpose of these files. References:
[Stylesheets], [Responsive web design]
NEW QUESTION # 33
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/_extend.less
- B. web/css/source/_extends.less
- C. web/css/source/_theme. less
Answer: A
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 # 34
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?
- A.
- B.
- C.
Answer: A
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.
