NEW QUESTION # 31
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 basic and mobile-specific styles.
- B. styles-i.less is used to generate desktop-specific styles and stytes-m.less is used to generate only 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: A
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 # 32
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. <span data-bind=Mil8n: 'Happy Birthday.'"></span>
- B. <!-- ko il8n = 'Happy Birthday.' --><!-- /ko -->
- 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 # 33
An Adobe Commerce developer was asked to customize a JavaScript component which is written as a function. How would the developer extend the native JavaScript function?
- A.
- B.
- C.
Answer: A
Explanation:
Explanation
To customize a JavaScript component that is written as a function, the developer can use option A. This option will use the prototype property of the function to extend its functionality and add new methods or properties.
For example:
function Component() { // Component logic }
Component.prototype.customMethod = function() { // Custom method logic }; This will create a new method called customMethod on the prototype of the Component function, which can be accessed by any instance of the Component object. The developer can also override existing methods or properties on the prototype by reassigning them with new values.
Option B is not correct because it will not extend the native JavaScript function, but create a new function that wraps the original function. This will not allow the developer to access or modify the properties or methods of the original function. Option C is not correct because it will not extend the native JavaScript function, but create a new object that inherits from the original function. This will not allow the developer to customize the original function itself, but only its instances.
NEW QUESTION # 34
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 # 35
An Adobe commerce developer wants to initialize a JavaScript component using a data attribute. Which option would initialize the JavaScript component?
- A. <nav data-mage-init='{"<component_name>": {...}}'></nav>
- B. <nav data-init='{"<component_name>": {...}}'></nav>
- C. <nav data-bind='{"<component_name>": {...}}'></nav>
Answer: A
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.

NEW QUESTION # 36
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/frontend/web/css/_module.less
- B. Custom/theme/Orange_Checkout/web/css/source/_module.less
- C. Custom/theme/web/css/source/Orange_Checkout/_module.less
Answer: B
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 # 37
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/less/source/lib/_buttons.less
- C. lib/web/css/source/lib/_button.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 # 38
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 $escaper->escapeUrl($url) ?>
- B. <?php echo $escaper->escapeHtml($url) ?>
- C. <?php echo $escaper->escapeLink($url) ?>
Answer: A
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 # 39
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.

NEW QUESTION # 40
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. scopes section in config.php file
- B. SCD_matrix deploy variable in .magento.env.yaml file
- C. relationships property in .magento.app.yaral 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 # 41
Which Ul component property is used for cross tracking property changes?
- A. listens
- B. links
- C. exports
Answer: A
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 # 42
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" destination="content" after="last-child"/>
- B. <moveelement = "country"destination="content" after="-"/>
- C. <move element="country-element"destination="content-element"/>
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],
[Move an element]

NEW QUESTION # 44
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 file merging
- D. Enable CSS critical path
Answer: D
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 # 45
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 D
- C. Option C
- D. Option B
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 # 46
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 # 47
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 a new theme, define a new website and customize in app/design.
app/design/frontend/Custom/Theme/Vendor_Module/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 another layout for the new website and configure new file.phtml.
app/code/Vendor/Module/view/frontend/templates/file.phtml
Answer: A
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 # 48
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. References: Adobe Commerce Developer Documentation, Adobe Inc.
NEW QUESTION # 49
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. /web/css/source/lib/.dropdowns.less
- B. /web/css/source/_dropdowns.less
- C. lib/web/css/source/.dropdowns.less
Answer: B
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 # 50
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 'Content", they set the "Path" field as "custom_page".
- B. Under 'Search Engine Optimization", they set the "URL Key" field as "custom_page''.
- C. Under "Page in Websites", they set the "URL" field as "custom.page".
Answer: B
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.]
