QuestionQ1

Adobe Experience Manager Sites

An Adobe Commerce developer is extending a theme from Magento\blank and needs to override the parent theme’s styles.

Which file must the developer change to override the parent theme styles?

  • A web/css/source/_extends.less
  • B web/css/source/_extend.less
  • C web/css/source/_theme.less
Explanation

In an Adobe Commerce theme that inherits from Magento/blank, web/css/source/_theme.less overrides the parent theme’s _theme.less variables. The _extend.less file is used to add or extend styles rather than replace the parent theme’s variable definitions.

QuestionQ2

Adobe Experience Manager Sites

An Adobe Commerce developer needs to override the template assigned to a block named existing.product.block. This relationship is defined in the catalog_product_view.xml layout of the Magento_Catalog module. They cannot merely override the file in their theme because the change belongs to a feature being released to the marketplace as a module named Orange_CustomProduct.

The developer has already created the required template at app/code/Orange/CustomProduct/view/frontend/templates/custom-product-block.phtml.

What can they add to app/code/Orange/CustomProduct/view/frontend/layout/catalog_product_view.xml in their module to achieve this?

  • A
  • B
  • C
  • D
Explanation

A referenceBlock targets the existing block, and an arguments node containing a string argument named template assigns its template declaratively. The identifier Orange_CustomProduct::custom-product-block.phtml resolves to the module’s view/frontend/templates/custom-product-block.phtml file. Adobe Commerce documents the template argument as a supported way to set a block template and recommends arguments over an <action> call when the block API permits it.

  • A <your_theme_dir>/web/
  • B <your_theme_dir>/Magento_Theme/web/

QuestionQ4

Adobe Experience Manager Sites

An Adobe Commerce developer is creating the Vendor/Orange theme and must customize the header used by email templates.

Where in the theme must the developer place the new template for this customization?

  • A /Magento_Email/templates/override/html/header.html
  • B /Magento_Email/email/header.html
  • C /Magento_Theme/html/header.html
Explanation

Theme-based email-template overrides are placed in <theme_dir>/<ModuleVendorName>_<ModuleName>/email. The default header template belongs to Magento_Email and is view/frontend/email/header.html, so its theme override is Magento_Email/email/header.html.

QuestionQ5

Adobe Experience Manager Sites

Which two actions are necessary to delete a manually installed theme?

Choose two
  • A Remove the theme using the theme:uninstall CLI command
  • B Remove the directory app/design/frontend/<VendorName>/<ThemeName>
  • C Disable the theme from the backend admin configuration
  • D Remove the theme record from the theme database table
Explanation

A manually installed, non-Composer theme must have its code removed from app/design/frontend/<VendorName>/<ThemeName> and its corresponding registration removed from the theme database table. The theme:uninstall command is for Composer-packaged themes, while disabling a theme does not remove its code or database record.
