AD0-E720 is a 50-question, 100-minute proctored exam with a 33/50 (66%) passing score and a US$225 fee. The blueprint splits weight across six domains: Theme Management (16%), Layout XML and Templates (22%), Styles (18%), JavaScript (22%), Admin Configuration and Page Builder (12%), and Tools (10%). Layout XML and JavaScript (Knockout, RequireJS, mage widgets, customer-data) tie as the heaviest sections at 22% each, so most study time should focus on layout merging rules, UI component scopes, and customer-data sections.

Sample Adobe Commerce Front-End Dev Expert Practice Questions

Try these sample questions to test your Adobe Commerce Front-End Dev Expert exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which Adobe Commerce file is the minimum required to register a new front-end theme?

A.registration.php only

B.theme.xml only

C.theme.xml and registration.php

D.composer.json and theme.xml

Explanation: A theme requires both theme.xml (declares the theme title, parent, and optional preview image) and registration.php (registers the component with ComponentRegistrar). composer.json is optional and only needed for distribution.

2In which directory must a custom front-end theme called Acme/luxury be placed?

A.app/code/Acme/Luxury

B.app/design/frontend/Acme/luxury

C.app/design/adminhtml/Acme/luxury

D.vendor/acme/luxury

Explanation: Front-end themes live under app/design/frontend/<Vendor>/<theme>. The vendor name is capitalized, the theme name is lowercase. app/code is for modules. adminhtml is for admin themes. vendor/ is for Composer-installed packages.

3How does a child theme inherit from a parent theme such as Magento/luma?

A.Adding extends="Magento/luma" to registration.php

B.Setting <parent>Magento/luma</parent> inside theme.xml

C.Copying every parent file into the child theme directory

D.Adding inherit_from="Magento/luma" to composer.json

Explanation: Theme inheritance is declared with the <parent> element inside theme.xml. Magento then resolves layout, templates, and static assets through the fallback chain ending at the parent. registration.php only registers the component path.

4Which file controls the available product image roles, dimensions, and aspect-ratio behavior for a theme?

A.etc/view.xml

B.etc/config.xml

C.Magento_Catalog/layout/catalog_product_view.xml

D.etc/di.xml

Explanation: etc/view.xml inside the theme defines media image types (small_image, image, thumbnail, swatch_image), their width, height, aspect-ratio, frame, and watermark settings, plus Page Builder breakpoints.

5Where must transactional-email template overrides be placed in a custom theme?

A.<theme>/email/

B.<theme>/Magento_Email/email/

C.<theme>/Magento_Email/templates/

D.<theme>/etc/email/

Explanation: Transactional emails are owned by Magento_Email. The theme override path is <theme>/Magento_Email/email/<template>.html. The module name folder mirrors the source module the template originally lives in.

6A merchant wants every word "Cart" replaced with "Bag" in the storefront. Which approach is the preferred theme-level method?

A.Override every phtml that contains the word Cart

B.Add a translation entry to the theme's i18n/<locale>.csv file

C.Edit the en_US locale CSV inside vendor/magento

D.Add a translation map to requirejs-config.js

Explanation: Theme-level translations are stored in <theme>/i18n/<locale>.csv with the format "original","translation". Magento merges theme CSVs after module CSVs, so the theme can override any wording without forking templates or core modules.

7Which CLI command extracts translatable phrases from a theme so they can be added to a CSV?

A.bin/magento i18n:export

B.bin/magento i18n:collect-phrases

C.bin/magento setup:static-content:deploy --translation

D.bin/magento dev:i18n:scan

Explanation: bin/magento i18n:collect-phrases scans PHP, phtml, and JavaScript files for translatable strings (__('...') and $t('...')) and writes them to a CSV you specify. It is the standard tool for building a translation dictionary for a theme or module.

8A theme inherits from Magento/blank but a layout file referenced only in Magento/luma is missing. What is the most likely cause?

A.Static content has not been deployed

B.The theme.xml parent points to Magento/blank, not Magento/luma

C.Layout caching is disabled

D.Magento_Theme module is disabled

Explanation: The fallback chain follows the <parent> declared in theme.xml. If the theme inherits from Magento/blank, Luma-only layout files are not part of the lookup. Changing the parent to Magento/luma would expose Luma's layout overrides.

9Which tag inside theme.xml controls the preview image displayed in Content > Design > Themes in the admin?

A.<preview>

B.<media><preview_image></preview_image></media>

C.<image><preview/></image>

D.<thumbnail>

Explanation: theme.xml uses <media><preview_image>media/preview.jpg</preview_image></media>. The path is relative to the theme root. The image is shown in the admin theme list and inside the theme details page.

10A new theme is registered but does not appear in the admin theme list. What command typically resolves this?

A.bin/magento cache:flush only

B.bin/magento setup:upgrade

C.bin/magento setup:di:compile

D.bin/magento maintenance:enable

Explanation: setup:upgrade scans registered components, populates the theme table, and runs schema updates. Without it, the new theme never gets a row in the theme table and remains invisible in the admin theme list.

Adobe Commerce Front-End Dev Expert Study Tips from Top Performers

1Spend the most study hours on Layout XML and JavaScript, because together they are 44% of the exam and most candidates lose points on layout merging order and Knockout viewModel wiring.

2Build a child theme of Luma end to end on a local 2.4.x install: register theme.xml, override a phtml, add a styles override, and deploy static content to make the workflow procedural rather than theoretical.

3Memorize the precedence rules for layout XML (module, parent theme, child theme) and the difference between referenceBlock, referenceContainer, move, and remove, because the exam loves layout-merge edge cases.

4Practice writing requirejs-config.js entries: shim, paths, map, and mixins. Know how to add a JavaScript mixin to an existing core component without forking the source.

5Understand customer-data sections: when sections invalidate, how Magento posts to /customer/section/load, and how to register a private section in sections.xml.

6Drill the Magento CLI commands and modes: setup:upgrade, setup:di:compile, setup:static-content:deploy, cache:clean vs cache:flush, and the difference between developer, default, and production modes.

7Review Page Builder: how content types are registered (view.xml, content type config XML, master and preview templates) and how to add a custom content type.

8Know the LESS entry points (styles-m.less for mobile-first, styles-l.less for desktop, print.less) and the _module.less plus _extend.less override pattern.
