An Adobe Commerce developer has been asked to add text to an email template that supports translations. Which two options would they use during their implementation? (Choose two.)
{{translations "Lorem Ipsum is simply dummy text of the printing"}}
{{translations "%items items" items="numltems"}}
{{trans "Lorem Ipsum is simply dummy text of the printing"}}
{{trans "%items items" items="numltems"}}
Answer:
Explanation:
To add text to an email template that supports translations, the developer should use the {{trans}} directive with the text enclosed in double quotes. For example:
{{trans “Lorem Ipsum is simply dummy text of the printingâ€}}
This will render the text as it is, or translate it if a translation file is available for the current locale. If the text contains a variable, the developer should use a placeholder with a percent sign and pass the variable name as an argument. For example:
{{trans “%items items†items=“numItemsâ€}}
This will render the text with the value of numItems replacing the %items placeholder, or translate it if a translation file is available for the current locale. The {{translations}}directive is not valid and will not work. References: [Translate email templates], [Email template syntax]
Which Ul component property is used for cross tracking property changes?
exports
listens
links
Answer:
Explanation:
 The listens property is used for cross tracking property changes in the UI component. The listens property defines the dependencies between the properties of different UI components. It allows one UI component to listen to the changes of another UI component’s property and react accordingly. For example, the listens property can be used to update the value of a text field based on the selection of a dropdown menu
An Adobe Commerce developer is using a view model within an existing block:
What are two ways to access the view model class in the template? (Choose two.)
$block->getData('view_model')
$block->viewModel()
$block->getViewHodel()
$block->getData('viewModel)
Answer:
Explanation:
To access a view model within an existing block, the developer can use either of the following ways:
- $block->getData(‘view_model’): This method will return the view model object that is assigned to the argument name “view_model†in the layout XML file. For example:
In the template file, the developer can access the view model object by using:
$block->getData(‘view_model’)
- $block->getData(‘viewModel’): This method will return the view model object that is assigned to the argument name “viewModel†in the layout XML file. For example:
In the template file, the developer can access the view model object by using:
$block->getData(‘viewModel’)
The following methods are not valid and will not work:
- $block->viewModel(): This method does not exist and will cause an error.
- $block->getViewHodel(): This method is misspelled and will cause an error.
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.
B)
By setting the node button-image in the theme's etc/view.xml file for the respective viewport configuration data.
C)By adding the node image in the theme's etc/viewport.xml file for the respective viewport configuration data.
D)
By adding the node image in the theme's etc/viewport.xml file for the respective viewport configuration data.
Option A
Option B
Option C
Option D
Answer:
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
An Adobe Commerce developer wants to apply a knockout binding to a
Answer:
Explanation:
To apply a knockout binding to a
- 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.
- C. : This solution will use the click binding to execute the onClick function as a reference when the
An Adobe Commerce developer needs to display a URL in the template. How would the variable $ur1be securely output in the template?
escapeUrl($url) ?>
escapeLink($url) ?>
escapeHtml($url) ?>
Answer:
Explanation:
To display a URL in a template securely, the developer should use the escapeUrl method of the escaper object. This method will encode any special characters in the URL that can be used for XSS attacks, such as &, <, >, ", ', etc. For example:
escapeUrl($url) ?>
The following methods are not suitable for displaying URLs and should not be used:
- escapeLink($url) ?>: This method is used for escaping link attributes, not URLs. It will encode any characters that are valid in URLs but invalid in HTML attributes, such as spaces, quotes, etc. For example:
escapeLink(‘https://example.com/?q=hello world’) ? > // Output: https://example.com/?q=hello%20world
- escapeHtml($url) ?>: This method is used for escaping HTML content, not URLs. It will encode any characters that are valid in URLs but invalid in HTML content, such as &, <, >, etc. For example:
escapeHtml(‘https://example.com/?q= ’) ?> // Output: https://example.com/?q=
An Adobe Commerce developer has been asked to implement a custom font specifically for emails. The Adobe Commerce developer has already added their font into the file system.
Keeping best practice in mind, which two files would need to be implemented to show the custom font in the email?
/Vendor/Theme/web/css/source/_extend.less
Use the ^import font function with the url of the custom font from the theme.
/Vendor/Theme/web/css/source/_email.less file
Add in the styles to target the elements that require being changed.
/vendor/Theme/web/css/source/_typography.less
Add in a lib-font-face mixin with the custom font name into the newly created file.
Add the font-family into the
of the email within the email template.Answer:
Explanation:
To implement a custom font specifically for emails, the developer needs to do the following steps:
- Add the custom font file to the web/fonts directory of the custom theme.
- Use the @import font function with the url of the custom font from the theme in the /Vendor/Theme/web/css/source/_extend.less file. This will import the custom font and make it available for use in other LESS files. For example:
@import font(‘custom-font’, ‘@{baseDir}fonts/custom-font.ttf’, ‘truetype’);
- Add in the styles to target the elements that require being changed in the /Vendor/Theme/web/css/source/_email.less file. This file is used to define the styles for email templates. The developer can use the .lib-font-face() mixin to apply the custom font to specific selectors. For example:
lib-font-face( @family-name: @custom-font, @font-path: ‘@{baseDir}fonts/custom-font’, @font-weight: normal, @font-style: normal );
h1 { .lib-font-face( @family-name: @custom-font, @font-path: ‘@{baseDir}fonts/custom-font’, @font-weight: normal, @font-style: normal ); }
The /vendor/Theme/web/css/source/_typography.less file is not suitable for implementing a custom font for emails, as it is used for defining global typography styles for web pages. The
tag is not used for adding fonts in email templates, as it is not supported by most email clients. References: [Custom fonts], [Email templates overview]An Adobe Commerce developer created a new CMS page and set the page title as "My Custom Page". The page must be accessible at the URL /custom_page.
Which CMS page configuration do they set to make the page accessible at /custom_page?
Under 'Content", they set the "Path" field as "custom_page".
Under 'Search Engine Optimization", they set the "URL Key" field as "custom_page’’.
Under "Page in Websites", they set the "URL" field as "custom.page".
Answer:
Explanation:
The URL Key field under the Search Engine Optimization section is used to specify the URL suffix for the CMS page. The developer can set it as “custom_page†to make the page accessible at /custom_page. The Path field under the Content section is used to specify the path to the template file that renders the CMS page content. The URL field under the Page in Websites section does not exist as a valid configuration option for CMS pages. References: [Adobe Commerce Developer Documentation], [Adobe Inc.]
An Adobe Commerce developer wants to override the template assigned to a block named existing, product, block. This relationship is defined in the catalog_product_view. xml layout in the Magento_Catalog module. They cannot simply override the file in their theme, as this change is part of a feature that is being released to the marketplace as a module called "Orange_CustomProduct".
The developer has already created the desired template at app/code/Orange/CustomProduct/view/f rontend/templates/custom-product-block.phtml.
What can they add to app/code/Orange/CustomProduct/view/f rontend/layout/catalog_product_view. xml in their module to accomplish this?
A)
B)
C)
D)
Option A
Option B
Option C
Option D

An Adobe Commerce developer has just installed an extension via composer. When running, bin/magento module: status Vendor_Module, the status is returned as Module is disabled.
Which two CLI commands need to be run to make the extension work properly? (Choose two.)
composer install
bin/magento setup:upgrade
composer update vendor/module
bin/magento module:enable Vendor_Module --clear-static-content
Answer:
Explanation:
The developer needs to run these two CLI commands to make the extension work properly:
- bin/magento module:enable Vendor_Module --clear-static-content This command enables the extension and clears any outdated static files that might interfere with its functionality.
- bin/magento setup:upgrade This command updates the database schema and data according to the extension’s requirements. The other two options are incorrect because they are not necessary to make the extension work properly. The composer install command installs all dependencies specified in the composer.json file, but it does not enable or update any extensions. The composer update vendor/module command updates an existing extension to its latest version, but it does not enable or upgrade it.
An Adobe Commerce developer has found following code:
After compiling the .less file into a .ess file, what will be the results of the code above?
A)
B)
C)
Option A
Option B
Option C
Answer:
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 “2sâ€, 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. References: [LESS Mixins], [CSS Animations]
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)
B)
C)
Option A
Option B
Option C
Answer:
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.
