Important Adobe AD0-E720 Exam Questions

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]

Answer: A

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.

Answer: B

Explanation:

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 <block> instead of <referenceBlock>, which would create a new block instead of referencing an existing one. Option C is not valid because it uses 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. Reference: [Layout instructions], [Override templates and layout files]

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

Answer: A, D

Explanation:

Template hints are a useful tool for frontend developers to determine which template is rendering a specific element on the storefront. Template hints can be turned on using either of these two methods:

In the Admin Panel, navigate to Stores > Configuration > Advanced > Developer > Debug. Set Enabled Template Path Hints for Storefront to Yes

On the command line, run the command; php bin/magento dev:template-hints:enable The other two options are incorrect because they do not exist as valid methods to turn on template hints. Reference:Adobe Commerce Developer Documentation,Adobe Inc.
