Question 1

An Adobe Commerce developer is trying to remove a block using the tag in a layout XML file but it shows an error and doesn't work. Which tag would be applied to fix the error?

Accepted Answer

A

Explanation: To remove a block using layout XML, the developer should use the tag with the name attribute specifying the name of the block and the remove attribute set to true. For example: This will remove the block from the layout and prevent it from rendering. The 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. Reference: [Layout instructions], [Remove an element]

Question 2

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. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_39_img_1.jpg B) By setting the node button-image in the theme's etc/view.xml file for the respective viewport configuration data. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_39_img_2.jpg C) By adding the node image in the theme's etc/viewport.xml file for the respective viewport configuration data. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_39_img_3.jpg D) By adding the node image in the theme's etc/viewport.xml file for the respective viewport configuration data. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_39_img_4.jpg

Accepted Answer

C

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

Question 3

An Adobe Commerce developer wants to completely overwrite _module. less of Orange_Checkout module, in their theme. Where would the developer place the file?

Accepted Answer

C

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. Reference: [Theme structure], [Module naming convention]

Question 4

An Adobe Commerce developer has found following code: https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_19_img_1.jpg After compiling the .less file into a .ess file, what will be the results of the code above? A) https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_19_img_2.jpg B) https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_20_img_1.jpg C) https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_20_img_2.jpg

Accepted Answer

B

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. Reference: [LESS Mixins], [CSS Animations]

Question 5

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

Accepted Answer

AC

Explanation: To apply a knockout binding to a to run a function, onClick(), when it’s clicked, the developer can use either of the following solutions: A. : This solution will use the click binding to execute the onClick() function as an expression when the 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. : This solution will use the click binding to execute the onClick function as a reference when the 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. : 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. : 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.

Question 6

An Adobe Commerce developer needs to modify the width and height of all product images inside the theme Vendor/theme. What file inside the theme is responsible for these changes?

Accepted Answer

B

Explanation: To modify the width and height of all product images inside a theme, the developer needs to edit the view.xml file inside the etc directory of the theme. The view.xml file contains the configuration for the theme’s images, fonts, and layout. The images.xml file does not exist by default and is not used for configuring images. The theme.xml file is used for specifying the parent theme and other metadata of the theme. Reference: [view.xml], [theme.xml]

Question 7

An Adobe Commerce developer is implementing a sticky sidebar using a jQuery widget. How would the developer initialize the block in a JavaScript file? A) https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_33_img_1.jpg B) https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_34_img_1.jpg C) https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Adobe_AD0-E720/page_34_img_2.jpg

Accepted Answer

C

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. https://experienceleague.adobe.com/docs/certification/program/technical-certifications/ac/acexpert/ac-e-fedeveloper0623.html?lang=en https://developer.adobe.com/commerce/docs/

Question 8

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?

Accepted Answer

B

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_t ype_layered.xml 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 tag with the name attribute specifying the name of the block and the remove attribute set to true. For example: The app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/layout/override/catalog_categor y_view_type_layered.xml 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. Reference: [Layout override], [Remove an element]

Question 9

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?

Accepted Answer

A

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. Reference: [Buttons], [Magento UI library]

Question 10

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?

Accepted Answer

C

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. Reference: [Layout instructions], [Override templates and layout files]
