Question #1

An Adobe Commerce developer wants to create symlinks for the frontend theme named Vendor/Orange using a CSS file: /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?

Reveal Solution Hide Solution
Correct Answer: B

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. Reference:Adobe Commerce Developer Documentation,Adobe Inc.


Question #2

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)

Reveal Solution Hide Solution
Correct Answer: B

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.

to run a function, onClick(), when it's clicked. Which two solutions would the developer use to achieve this? (Choose two.)
