An Adobe Commerce developer wants to create a sticky widget.
How would the widget be initialized using the data-mage-init attribute?
A)
B)
C)
Answer : B
Option B is the correct way to initialize a widget using the data-mage-init attribute. The attribute value should be a JSON object with the widget name as the key and the widget options as the value. Option A is incorrect because it uses a string instead of an object for the attribute value. Option C is incorrect because it uses a colon instead of a comma to separate the widget name and the options.
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, C
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.

An Adobe Commerce developer created a module called Orange_Customer. In customer information.
Where would the developer place this file?
Answer : C
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.
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 : B
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. Reference: [LESS Mixins], [CSS Animations]
An Adobe Commerce developer wants to initialize a JS component via Layout XML in custom reference block test. component. Which Layout XML instruction would be used to initialize this JS component?
A)
B)
C)
Answer : A
Option A is the correct way to initialize a JS component via Layout XML in a custom reference block. The x-magento-init tag is used to specify the component name and the options. Option B is incorrect because it uses the data-mage-init attribute, which is only valid for HTML elements. Option C is incorrect because it uses the x-magento-component tag, which is deprecated and should not be used.
