AD0-E720 Dumps with Practice Exam Questions Answers

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]

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]

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]

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]

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 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.
