NEW QUESTION # 19
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 # 20
Which two steps are required to delete a manually installed theme? (Choose two.)
- A. Remove the directory app/design/frontend/<VendorNAME/<ThemeName>
- B. Remove the theme using the theme:uninstall CLI command
- C. Remove the theme record from the theme database table
- D. Disable the theme from the backend admin configuration
Answer: A,C
Explanation:
Explanation
To delete a manually installed theme, the developer needs to remove the theme directory from the app/design/frontend directory and also delete the corresponding record from the theme table in the database.
The theme:uninstall CLI command is only used for deleting themes thatare installed as Composer packages.
Disabling the theme from the backend admin configuration does not delete the theme files or records, but only makes it unavailable for use. References: [Delete a theme], [theme:uninstall]
NEW QUESTION # 21
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?
- A.
- B.
- C.
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 # 22
An Adobe Commerce developer needs to improve the time of first render of the pages. How would the developer achieve this?
- A. Enable JavaScript minification
- B. Use the quick static files deployment strategy
- C. Enable CSS critical path
- D. Enable CSS file merging
Answer: C
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.

NEW QUESTION # 23
What is the difference between styles-l.less and styles-m.less ?
- A. styles-i.less is used to generate basic and mobile-specific styles and stytes-m.less is used to generate desktop-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 desktop-specific styles and stytes-m.less is used to generate only mobile-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:

NEW QUESTION # 24
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_Catalog/layout/catalog_category_view.xml
- B. app/design/frontend/Vendor/Theme/Magento_Layered.Navigation/layout/catalog_category_view_type_lay
- C. app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/layout/override/catalog_category_view_
Answer: B
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 # 25
an Adobe commerce developer wants to override the core Magento Ul library dropdowns in your theme.
Which is the correct way to achieve this?
- A. lib/web/css/source/.dropdowns.less
- B. /web/css/source/lib/.dropdowns.less
- C. /web/css/source/_dropdowns.less
Answer: C
Explanation:
Explanation
To override the core Magento UI library dropdowns in a custom theme, the developer needs to create a file named _dropdowns.less in the /web/css/source directory of the theme. This file will override the default
_dropdowns.less file from the lib/web/css/source/lib directory and apply the custom styles to the dropdown elements. The lib/web/css/source/_dropdowns.less and /web/css/source/lib/_dropdowns.less files are not valid and will not work, as they do not follow the theme structure or the naming convention. References:
[Dropdowns], [Theme structure]
NEW QUESTION # 26
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->viewModel()
- B. $block->getData('viewModel)
- C. $block->getViewHodel()
- D. $block->getData('view_model')
Answer: B,D
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 # 27
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>/layouts. xml
- B. app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layout/layouts.xml
- C. app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layouts.xnil
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 # 28
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: 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.

NEW QUESTION # 29
An Adobe Commerce developer wants to create symlinks for the frontend theme named Vendor/Orange using a CSS file: <magento_root>/pub/static/frontend/Vendor/Orange/en_US/css/styles-l.css during development.
Which CLI command would the developer use to create symlinks for the en_US locale?
- A. bin/magento dev:theme:deploy --locale="en__US" --theme="Vendor/Orange" css/styles-1
- B. bin/magento deploy:mode:set theme --locale="en_US" --area="frontend" css/styles-1
- C. bin/magento dev:source-theme:deploy --type=Mless" --locale="en_US" --theme="Vendor/Orange" css/styles-1
Answer: C
Explanation:
Explanation
The bin/magento dev:source-theme:deploy command is used to create symlinks for frontend theme files during development. This command allows the developer to modify source files without running static content deployment every time. The developer can use parameters to specify the type, locale, theme, and file names for creating symlinks. For example, to create symlinks for a CSS file named styles-l.css for the Vendor/Orange theme and the en_US locale, the developer can use:
bin/magento dev:source-theme:deploy --type=less --locale=en_US --theme=Vendor/Orange css/styles-l The other two options are incorrect because they do not create symlinks for frontend theme files. The bin/magento dev:theme:deploy command is used to register themes with Magento and clear caches. The bin/magento deploy:mode:set command is used to change the application mode.

NEW QUESTION # 30
An Adobe Commerce developer wants to initialize a JS component via Layout XML in custom reference block test. component. Which Layout XML instruction would be used to initialize this JS component?
- A.
- B.
- C.
Answer: C
Explanation:
Explanation
Option A is the correct way to initialize a JS component via Layout XML in a custom reference block. The x-magento-init tag is used to specify the component name and the options. Option B is incorrect because it uses the data-mage-init attribute, which is only valid for HTML elements. Option C is incorrect because it uses the x-magento-component tag, which is deprecated and should not be used.

Explanation
Template hints are a useful tool for frontend developers to determine which template is rendering a specific element on the storefront. Template hints can be turned on using either of these two methods:
In the Admin Panel, navigate to Stores > Configuration > Advanced > Developer > Debug. Set Enabled Template Path Hints for Storefront to Yes On the command line, run the command; php bin/magento dev:template-hints:enable The other two options are incorrect because they do not exist as valid methods to turn on template hints.

NEW QUESTION # 32
An Adobe Commerce developer has created a system configuration field:
Using Layout XML, how can the visibility of a block be controlled by a system configuration?
- A. <block name="block.name" template=''Vendor_Module:
:template.phtml"ifconfig="module/general/enable" /> - B. <block name="block.name" template="Vendor_Module::template.phtml="
ifconfig="vendor/general/enable" /> - C. <block name="block.name" template="Vendor_Module::template.phtml"
ifconfig="general/module/enable" />
Answer: B
Explanation:
Explanation
To control the visibility of a block using a system configuration, the developer should use the ifconfig attribute in the <block> tag. The ifconfig attribute should specify the path to the system configuration field that determines whether the block is visible or not. For example:
<block name="block.name" template="Vendor_Module::template.phtml" ifconfig="vendor/general/enable" /> This will render the block only if the vendor/general/enable system configuration field is set to true. The module/general/enable and general/module/enable paths are not valid and will not work, as they do not match the system configuration field defined in the image. References: [Layout instructions], [System configuration]
NEW QUESTION # 33
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. /catalog_product_view.xml
- B. /override/ExampleCorp/blank/catalog_product_view.xml
- C. /override/theme/ExampleCorp/blank/catalog_product_view.xml
Answer: A
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 # 34
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.)
- A.
- B.
- C.
- D.
Answer: A,D
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 # 35
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_Email/email/header.html
- B. /Magento_Email/templates/override/html/header.html
- C. /Magento_Theme/html/header.html
Answer: A
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 # 36
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. <moveelement = "country"destination="content" after="-"/>
- C. <move element="country" destination="content" after="last-child"/>
Answer: B
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 # 37
In which mode would the stylesheet customizations display immediately after you reload a page in a browser?
- A. less-side compilation mode
- B. client-side compilation mode
- C. server- side compilation mode
Answer: B
Explanation:
Explanation
In client-side compilation mode, the stylesheet customizations will display immediately after reloading a page in a browser. This is because in this mode, the LESS files are compiled into CSS files by the browser using JavaScript. This mode is useful for development and debugging purposes, as it allows quick changes and previews of the styles. However, this mode is not recommended for production, as it can affect the performance and compatibility of the site. The other modes, server-side compilation and LESS compilation, require running commands or tools to compile the LESS files into CSS files on the server side, which can take some time and delay the display of the customizations. References: [Compilation modes], [Compile LESS]
NEW QUESTION # 38
An Adobe commerce developer wants to initialize a JavaScript component using a data attribute. Which option would initialize the JavaScript component?
- A. <nav data-init='{"<component_name>": {...}}'></nav>
- B. <nav data-bind='{"<component_name>": {...}}'></nav>
- C. <nav data-mage-init='{"<component_name>": {...}}'></nav>
Answer: C
Explanation:
Explanation
To initialize a JavaScript component using a data attribute, the developer should use the data-mage-init attribute. This attribute allows the developer to specify the name and configuration of the component in a JSON format. For example:
<nav data-mage-init='{"Vendor_Module/js/nav": {"option1": "value1", "option2": "value2"}}'></nav> This will initialize the nav component from the Vendor_Module/js/nav file with the given options. The data-bind and data-init attributes are not valid and will not work, as they are not supported by Magento.
