NEW QUESTION # 29
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.)
- A. $block->getViewHodel()
- B. $block->getData('viewModel)
- C. $block->viewModel()
- D. $block->getData('view_model')
Answer: B,D
Explanation:
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:
<referenceBlock name="blog_posts_list"> <arguments> <argument name="view_model" xsi:type="object">ExampleObjectModel/ExampleObjectModel</argument> </arguments> </referenceBlock> 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:
<referenceBlock name="blog_posts_list"> <arguments> <argument name="viewModel" xsi:type="object">ExampleObjectModel/ExampleObjectModel</argument> </arguments> </referenceBlock> 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.
NEW QUESTION # 30
An Adobe Commerce developer created a module called Orange_Customer. In customer information.
Where would the developer place this file?
- A. app/code/OrangG/customer/viev^/frontend/web/templates/customer-info.phtml
- B. app/code/Orange/Customer/frontend/templates/customer-info.phtml
- C. app/code/OrangG/Custon>Gr/viGw/frontGnd/templates/customGr-info.phtml
Answer: C
Explanation:
Explanation
To place a template file for a custom module, the developer should follow this path pattern:
app/code/<Vendor>/<Module>/view/<Area>/templates/<Template>
In this case, the vendor name is Orange, the module name is Customer, the area is frontend, and the template name is customer-info.phtml. Therefore, the correct path is:
app/code/Orange/Customer/view/frontend/templates/customer-info.phtml
The following paths are not correct and will not work:
app/code/Orange/customer/view/frontend/web/templates/customer-info.phtml: This path is incorrect because it uses web instead of templates, which is used for storing web assets like CSS, JS, and images, not template files.
app/code/Orange/Customer/frontend/templates/customer-info.phtml: This path is incorrect because it misses the view directory, which is required for separating frontend and backend templates.
NEW QUESTION # 31
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.)
- A. {{translations "Lorem Ipsum is simply dummy text of the printing"}}
- B. {{trans "Lorem Ipsum is simply dummy text of the printing"}}
- C. {{translations "%items items" items="numltems"}}
- D. {{trans "%items items" items="numltems"}}
Answer: C,D
Explanation:
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 printing"}}
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="numItems"}}
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.

NEW QUESTION # 32
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.
Answer: C
Explanation:
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 "2s", 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]
NEW QUESTION # 33
An Adobe Commerce developer wants to apply a knockout binding to a <div> to run a function, onClick(), when it's clicked. Which two solutions would the developer use to achieve this? (Choose two.)
- A. <div data-bind="click: onClick()"><x/div>
- B. <div data-bind="click: onClick"></div>
- C. <div click=,,onClick"X/div>
- D. <div><!-- ko click: 'onClick' --> <!-- /ko --></div>
Answer: A,B
Explanation:
Explanation
To apply a knockout binding to a <div> to run a function, onClick(), when it's clicked, the developer can use either of the following solutions:
A: <div data-bind="click: onClick()"></div>: This solution will use the click binding to execute the onClick() function as an expression when the <div> 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: <div data-bind="click: onClick"></div>: This solution will use the click binding to execute the onClick function as a reference when the <div> 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: <div><!-- ko click: 'onClick' --><!-- /ko --></div>: 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: <div click="onClick"></div>: 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.
NEW QUESTION # 34
An Adobe Commerce developer needs to debug an issue, where the path of the block template was invalid and the warning was added to a log file. Which mode are errors only written to a log file and not displayed?
- A. developer only
- B. default and production
- C. developer and default
Answer: B
Explanation:
Explanation
The default and production modes are the modes where errors are only written to a log file and not displayed on the screen. This is done to prevent exposing sensitive information to users and attackers. The default mode is the mode that Adobe Commerce runs in by default if no other mode is specified. The production mode is the mode that Adobe Commerce runs in when it is deployed to a live site. The developer can use the following command to check the current mode:
bin/magento deploy:mode:show
The other two options are incorrect because they display errors on the screen as well as writing them to a log file. The developer mode is the mode that Adobe Commerce runs in when it is under development or testing.
The developer mode enables enhanced debugging and error reporting features. References: Adobe Commerce Developer Documentation, Adobe Inc.
NEW QUESTION # 35
An Adobe Commerce developer wants to add a custom widget that extends the default Calendar Widget. What would the contents of this file look like?
- A.
- B.
- C.
Answer: C
Explanation:
Explanation
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.

NEW QUESTION # 36
Which two steps are required to delete a manually installed theme? (Choose two.)
- A. Disable the theme from the backend admin configuration
- B. Remove the directory app/design/frontend/<VendorNAME/<ThemeName>
- C. Remove the theme using the theme:uninstall CLI command
- D. Remove the theme record from the theme database table
Answer: B,D
Explanation:
Explanation
To delete a manually installed theme, the developer needs to remove the theme directory from the app/design/frontend directory and also delete the corresponding record from the theme table in the database.
The theme:uninstall CLI command is only used for deleting themes thatare installed as Composer packages.
Disabling the theme from the backend admin configuration does not delete the theme files or records, but only makes it unavailable for use. References: [Delete a theme], [theme:uninstall]
NEW QUESTION # 37
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?
- A. Under 'Search Engine Optimization", they set the "URL Key" field as "custom_page''.
- B. Under "Page in Websites", they set the "URL" field as "custom.page".
- C. Under 'Content", they set the "Path" field as "custom_page".
Answer: A
Explanation:
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.]
NEW QUESTION # 38
An Adobe Commerce developer is customizing buttons for a custom theme that inherits Magento/blank theme and needs to override the default values. Where would the default values for the buttons be located?
- A. lib/web/css/source/lib/_buttons.less
- B. lib/web/css/source/lib/_button.less
- C. lib/web/less/source/lib/_buttons.less
Answer: A
Explanation:
Explanation
To find the default values for the buttons, the developer needs to look at the lib/web/css/source/lib/_buttons.less file. This file contains various variables, mixins, and styles for defining and customizing buttons. The developer can override these values in their custom theme by using the
.lib-button() mixin or by creating their own mixins or classes. For example:
lib-button( @_button-selector, @_button-type, @_button-shape, @_button-color, @_button-background,
@_button-border, @_button-text-transform, @_button-box-shadow, @_button-hover-color,
@_button-hover-background, @_button-hover-border, @_button-hover-box-shadow ); The lib/web/less/source/lib/_buttons.less and lib/web/css/source/lib/_button.less files are not valid and do not exist. References: [Buttons], [Magento UI library]
NEW QUESTION # 39
An Adobe Commerce developer needs to improve the time of first render of the pages. How would the developer achieve this?
- A. Enable CSS critical path
- B. Enable CSS file merging
- C. Enable JavaScript minification
- D. Use the quick static files deployment strategy
Answer: A
Explanation:
Explanation
CSS critical path is a feature that improves the time of first render of the pages by inlining the CSS rules that are required to render the above-the-fold content of the page. This reduces the number of requests and bytes that need to be downloaded before the page is rendered. CSS critical path can be enabled in the Admin Panel by navigating to Stores > Configuration > Advanced > Developer > CSS Settings and setting Enable CSS Critical Path to Yes. References: Adobe Commerce Developer Documentation, Adobe Inc.
NEW QUESTION # 40
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?
- A. Add in the styles to target the elements that require being changed.
/vendor/Theme/web/css/source/_typography.less - B. Add the font-family into the <head></head> of the email within the email template.
- C. /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 - D. Add in a lib-font-face mixin with the custom font name into the newly created file.
Answer: A,C
Explanation:
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 <head></head> 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]
NEW QUESTION # 41
An Adobe Commerce developer is extending a theme from Magento\blank and wants to override parent styles.
Which file does the developer need to change to override the parent theme styles?
- A. web/css/source/_theme. less
- B. web/css/source/_extends.less
- C. web/css/source/_extend.less
Answer: C
Explanation:
Explanation
To override the parent theme styles, the developer needs to change the web/css/source/_extend.less file in the child theme. This file is used to import and extend the parent theme styles without modifying the original files.
The developer can use the @import directive to import the parent theme styles and then use the .lib-css() mixin to override the CSS properties. For example:
@import 'source/_extend.less'; // Import parent theme styles .lib-css(color, red); // Override color property The web/css/source/_extends.less and web/css/source/_theme.less files are not valid and will not work, as they do not follow the theme structure or the naming convention. References: [Theme inheritance], [Extend parent theme styles]
NEW QUESTION # 42
An Adobe Commerce developer needs to add a conditional static note depending on whether the order type is virtual or not. Which option would the developer use to add the conditional text in the email template?
- A.
- B.
- C.
Answer: C
Explanation:
Explanation
Option B is the correct way to add a conditional static note depending on whether the order type is virtual or not in the email template. Option B uses the {{trans}} directive to translate the text and the {{depend}} directive to check the value of the order.is_virtual variable. If the order is virtual, the text "Shipping not required." will be displayed. Option A and Option C are incorrect because they use the wrong syntax for the
{{trans}} and {{depend}} directives. Option A uses curly braces instead of parentheses for the {{trans}} directive and does not use quotes for the text. Option C uses parentheses instead of curly braces for the
{{depend}} directive and does not use a dot to access the order.is_virtual variable.
NEW QUESTION # 43
An Adobe Commerce developer wants to create symlinks for the frontend theme named Vendor/Orange using a CSS file: <magento_root>/pub/static/frontend/Vendor/Orange/en_US/css/styles-l.css during development.
Which CLI command would the developer use to create symlinks for the en_US locale?
- A. bin/magento deploy:mode:set theme --locale="en_US" --area="frontend" css/styles-1
- B. bin/magento dev:source-theme:deploy --type=Mless" --locale="en_US" --theme="Vendor/Orange" css/styles-1
- C. bin/magento dev:theme:deploy --locale="en__US" --theme="Vendor/Orange" css/styles-1
Answer: B
Explanation:
Explanation
The bin/magento dev:source-theme:deploy command is used to create symlinks for frontend theme files during development. This command allows the developer to modify source files without running static content deployment every time. The developer can use parameters to specify the type, locale, theme, and file names for creating symlinks. For example, to create symlinks for a CSS file named styles-l.css for the Vendor/Orange theme and the en_US locale, the developer can use:
bin/magento dev:source-theme:deploy --type=less --locale=en_US --theme=Vendor/Orange css/styles-l The other two options are incorrect because they do not create symlinks for frontend theme files. The bin/magento dev:theme:deploy command is used to register themes with Magento and clear caches. The bin/magento deploy:mode:set command is used to change the application mode. References: Adobe Commerce Developer Documentation, Adobe Inc.
NEW QUESTION # 44
An Adobe Commerce developer needs to apply a Knockout binding to show content under certain conditions.
Which two syntaxes would achieve this? (Choose two.)
- A.
- B.
- C.
- D.
Answer: A,D
Explanation:
Explanation
Option A and Option C are both valid ways to apply a Knockout binding to show content under certain conditions. Option A uses the visible binding, which sets the display style of the element to none if the value is false. Option C uses the if binding, which removes or inserts the element from the DOM based on the value.
Option B and Option D are incorrect because they use invalid syntax for Knockout bindings. Option B uses a colon instead of an equal sign to assign the value, and Option D uses a single quote instead of a double quote to enclose the value.

NEW QUESTION # 45
An Adobe Commerce developer was asked to customize a JavaScript component which is written as a function. How would the developer extend the native JavaScript function?
- A.
- B.
- C.
Answer: A
Explanation:
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.
