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.)
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''>
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''>
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.
An Adobe Commerce developer wants to create symlinks for the frontend theme named Vendor/Orange using a CSS file:
Which CLI command would the developer use to create symlinks for the en_US locale?
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
An Adobe Commerce developer wants to remove the default Wishlist and Compare Products blocks on a category page with layered navigation Where would this modification be placed, assuming the developer only wants to make this change?
To remove the default Wishlist and Compare Products blocks on a category page with layered navigation, the developer should place the modification in the app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/layout/catalog_category_view_type_layered.xml file. This file is specific to the category pages with layered navigation and will override the default layout file from the Magento_LayeredNavigation module. The modification should use the <referenceBlock> tag with the name attribute specifying the name of the block and the remove attribute set to true. For example:
<referenceBlock name=''catalog.compare.sidebar'' remove=''true''/> <referenceBlock name=''wishlist_sidebar'' remove=''true''/>
The app/design/frontend/Vendor/Theme/Magento_LayeredNavigation/layout/override/catalog_category_view_type_layered.xml file is not valid and will not work, as it is not a valid override path. The app/design/frontend/Vendor/Theme/Magento_Catalog/layout/catalog_category_view.xml file is not specific to the category pages with layered navigation and will affect all category pages.

An Adobe Commerce developer needs to pass JSON data to a JavaScript component while keeping XSS prevention strategies in mind.
Which two options would the developer use? (Choose two.)
A)
C)
D)
To pass JSON data to a JavaScript component while keeping XSS prevention strategies in mind, the developer should use the following options:
Option A: Use the x-magento-init script tag with the data-mage-init attribute and the JSON.parse function to initialize the component with the JSON data. This option is secure because it does not use any HTML tags or attributes that can be exploited by XSS attacks.
Option C: Use the text/x-magento-init script tag with the type attribute and the JSON.parse function to initialize the component with the JSON data. This option is secure because it does not use any HTML tags or attributes that can be exploited by XSS attacks.
The following options are not secure and should not be used:
Option B: Use the script tag with the type attribute and the escapeHtmlAttr function to initialize the component with the JSON data. This option is not secure because it uses the escapeHtmlAttr function, which is meant for escaping HTML attributes, not JSON data. This function can introduce double quotes in the JSON data, which can break the JSON syntax and cause errors.
Option D: Use the script tag with the type attribute and the escapeJsQuote function to initialize the component with the JSON data. This option is not secure because it uses the escapeJsQuote function, which is meant for escaping JavaScript strings, not JSON data. This function can introduce backslashes in the JSON data, which can break the JSON syntax and cause errors.
An Adobe Commerce developer needs to alias URLs and third party libraries inside a require js-config.js file. Which configuration would the developer use?
A)
B)
C)
To alias URLs and third party libraries inside a requirejs-config.js file, the developer should use the paths configuration option. This option allows the developer to map module names to URLs or paths relative to the baseUrl. For example:
var config = { paths: { 'jquery': 'https://code.jquery.com/jquery-3.6.0.min', 'custom': 'Vendor_Module/js/custom' } };
This will map the module name 'jquery' to the URL of the jQuery library and the module name 'custom' to the path of the custom module. The developer can then use these module names in other modules or files without specifying the full URL or path.
Option A is not correct because it uses the shim configuration option, which is used to define dependencies and exports for non-AMD modules, not to alias URLs or paths. Option C is not correct because it uses the map configuration option, which is used to map module names to other module names for specific contexts, not to alias URLs or paths.
