AD0-E717 Adobe Commerce Developer Professional Questions and Answers

According to the Adobe Commerce Developer Documentation, one way a developer can upgrade the ECE-Tools package on an Adobe Commerce Cloud project is by using Composer, which is a dependency management tool for PHP projects. The ECE-Tools package contains scripts and tools that help manage and deploy Adobe Commerce Cloud projects on the cloud infrastructure. To upgrade the ECE-Tools package using Composer, the developer needs to run the following command in the project root directory:

composer update magento/ece-tools --with-dependencies

On an Adobe Commerce Cloud project, the recommended way to upgrade the ECE-Tools package is through Composer, a dependency manager for PHP. Composer is used to managethe dependencies of the project, including ECE-Tools, and it provides the necessary commands to update packages to their latest versions or to specific versions as required.

The read-only core file system on Adobe Commerce Cloud ensures that all changes to the production environment are tracked. This is because any changes to the code must go through version control, and the deployment pipeline, which includes stages like build, staging, and production. This approach helps maintain consistency across environments, ensures deployment best practices, and reduces human error by preventing direct changes on production servers.

The two attribute input types that Adobe Commerce already has by default are Multiple Select and Text Field. Multiple Select allows the user to select multiple values from a list of options. Text Field allows the user to enter text in a single line.

The Geographic coordinate and Numeric Field input types do not exist in Adobe Commerce.

Magento, by default, provides various attribute input types to accommodate different data entry needs for product and customer attributes. The "Text Field" input type allows for single-line text input, suitable for short, textual data such as names, titles, or any other brief information. The "Multiple Select" input type enables the selection of multiple options from a predefined list, useful for attributes with multiple applicable values like colors, sizes, or features. These input types are part of Magento's flexible attribute system, allowing for customizable data entry fields that cater to diverse product and customer data requirements.

The Discard Subsequent Rules option is only applied if the pricing rules have different priorities. If two pricing rules have the same priority, the discount from both rules will be applied.

For the "Discard Subsequent Rules" option set to "Yes" to work effectively, each pricing rule must have a defined priority. When multiple discount rules can apply to the same product, Magento evaluates them in the order of their priority values. If a rule with "Discard Subsequent Rules" set to "Yes" is applied, any subsequent rules with lower priority (higher priority number) will not be applied to that product.

To access RabbitMQ data on an Adobe Commerce Cloud Production environment, you can use local port forwarding. This allows you to forward a port on your local machine to a port on the Production environment. This way, you can connect to RabbitMQ from your local machine.

A developer would access RabbitMQ data on an Adobe Commerce Cloud Production environment using local port forwarding. This is done via an SSH tunnel that securely forwards a port from the local machine to the RabbitMQ service on the cloud environment. RabbitMyAdmin (an option that does not exist) and the Project Web Interface do not provide direct access to RabbitMQ data.

When renaming a table in Magento, to prevent data loss, the developer must define the table and its columns mapping in thedb_schema_whitelist.jsonfile. This declarative schema approach ensures that the data migration tool knows about the changes and can migrate data from the old table to the newly named table without losing any data.

Thewebdirectory contains the static files that can be loaded directly. This directory includes files such as CSS, JavaScript, and images.

In Adobe Commerce themes, thewebdirectory is used to store static files such as CSS, JavaScript, images, and fonts. These files can be loaded directly by the browser. Thepreprocessedandassetsdirectories do not exist as standard directories in the theme structure for containing directly loadable static files.

This file provides the shipping address of the current quote by using the getShippingAddress() method. For example, the following code snippet gets the shipping address from the quote object and logs it to the console:

define([

'Magento_Checkout/js/model/quote'

],function(quote) {

'use strict';

varshippingAddress = quote.getShippingAddress();

console.log(shippingAddress);

});

The file Magento_Quote/js/model/model does not exist in Magento 2, and the file Magento_Checkout/js/model/quote-shipping-address is not a valid way to access the shipping address of the current quote. You can read more about the quote object and its methods in the Magento 2 developer documentation.

In Adobe Commerce, the shipping address of the current quote is accessed through the JavaScript fileMagento_Checkout/js/model/quote. This file includes various quote-related data, including shipping and billing addresses, items in the cart, and totals. There is noMagento_Checkout/js/model/quote-shipping-addressfile, andMagento_Quote/js/model/modelis not a valid path, making option A the correct choice.

To display a custom attribute on the category edit page in the Magento admin panel, a developer should use the UI component approach. This involves creating acategory_form.xmlfile within theview/adminhtml/ui_componentdirectory of the module. This XML file defines the form fields (including any custom attributes) that should appear on the category edit page. The UI component system in Magento provides a flexible way to manage form elements and their interactions on the admin side, ensuring a consistent user interface and experience​​.

On the Adobe Commerce Cloud Project Web Interface, clicking on the "Delete" button of an integration environment will completely delete the environment, including the associated git branch and database. This action is irreversible and is used to remove an environment that is no longer needed. The environment, once deleted, frees up resources for the project and cannot be restored.

A URL Rewrite in Magento changes the way a URL appears in the browser. This is particularly useful for improving the readability and SEO of a URL. For example, a URL rewrite can be used to transform a long and complex URL into a shorter and more user-friendly version. It's important to note that while a URL rewrite changes the URL's appearance in the browser, it doesn't change the actual location of the resource on the server. This distinction is crucial for understanding how Magento handles URL rewrites and redirects, facilitating a more intuitive navigation structure within the store without altering the underlying server resources​​.

The Adobe Commerce table that stores all cron job data iscron_schedule. This table maintains records of all scheduled cron tasks, including their statuses, execution times, and any messages related to their execution. It plays a central role in Magento's scheduling system, allowing for the management and monitoring of background tasks that are essential for various system functions and integrations​​.

Theview/{area}/web/css/source/main.lessfile is the default less file that is included by default. This file contains the main styles for the module.

In a custom module in Adobe Commerce, the default location for including custom LESS styles is typicallyview/{area}/web/css/source/_module.less. However, the most commonly used file for adding global styles isview/{area}/web/css/source/_extend.less. Theview/{area}/web/css/style.lessfile is not standard, and themain.lessfile is used as an entry point for compilation but typically does not contain custom styles directly.

The way a developer would access RabbitMQ data on an Adobe Commerce Cloud Production environment is by using local port forwarding. This method allows the developer to connect to the RabbitMQ service instance through an SSH tunnel and access the RabbitMQ Management UI from a web browser. The developer needs to use the magento-cloud ssh command to establish the SSH connection and the $MAGENTO_CLOUD_RELATIONSHIPS variable to retrieve the RabbitMQ connection details and login credentials. 

To set a custom CMS Page as a store home page, the developer or merchant should follow these steps:

• In the Admin panel, go to Content > Pages and create or edit a CMS Page that will be used as a home page.
• In the Admin panel, go to Stores > Configuration > General > Web > Default Pages.
• In the CMS Home Page field, select the CMS Page that was created or edited in step 1.
• Save the configuration.

There is no “Home Page” column in the CMS Page admin grid or “Default Home Page” value in the CMS Page admin form.

In Adobe Commerce, to set a custom CMS page as the store's homepage, you need to go to the store configuration. Specifically, navigate to Content > Design > Configuration, select therelevant store view, and then under the "Default Pages" tab, set the "CMS Home Page" option to your custom CMS page. Options A and B do not exist in the Adobe Commerce admin panel for setting a home page.

For an Adobe Commerce Cloud project, the only writeable folders in the application root on a remote environment are essential for the application to run correctly and store temporary and dynamic data. Among the options given, Option B lists directories that are typically writable:m2-hotfixes,var,pub/static, andapp/etc. Them2-hotfixesdirectory is specifically for Magento Commerce Cloud and is used for applying hotfixes that are executed during the build phase. Thevardirectory contains various logs, sessions, and reports. Thepub/staticdirectory holds the compiled static view files, andapp/etccontains configuration files that can be modified by the application at runtime.

Informing the Adobe Support team about a planned traffic surge allows them to monitor the website during that time. With prior notice, the support team can ensure that they are prepared to quickly respond to any issues that arise due to the surge. While extra server resources or an upgraded Fastly plan may be possible outcomes, the primary advantage of advance notice is proactive monitoring and support during expected high traffic events.

Multiple EAV attributes belonging to the same entity are grouped in the database based on their data types, such as datetime, decimal, int, text, or varchar. For example, all attributes with datetime values are stored in one table, while all attributes with text values are stored in another table.

The sizes or numeric/text values of attributes do not determine how they are grouped in the database.

Magento's EAV (Entity-Attribute-Value) model organizes attributes based on their data types to optimize storage and retrieval. Attributes are grouped into different tables based on whether they store values of types such as integer, varchar (text), decimal, datetime, etc. This organization allows Magento to efficiently manage the diverse data types associated with products, customers, and other entities, ensuring data integrity and optimizing database performance by using appropriate indexing and storage mechanisms for each data type.

If a developer wants to allow the removal of columns from the database when deleting them fromdb.schema.xml, they need to define the removable columns in thedb_schema_whitelist.jsonfile. This file will tell Magento which columns can be removed from the database.

To allow columns to be removed from the database when they are deleted fromdb_schema.xml, they must be listed in thedb_schema_whitelist.jsonfile. This file acts as a reference for which database schema elements are safe to modify or delete, providing a safeguard against unintentional data loss during schema updates.

To enable filtering by attribute in a category's layered navigation, you should set the category's "Is Anchor" setting to "Yes". This setting is found in the category's display settings within the admin panel. When a category is set as "Anchor", Magento will automatically include filtering options in the layered navigation block for all attributes that are configured to be used in layered navigation.
