AD0-E717 Practice Exam Questions with Answers Adobe Commerce Developer Professional Certification

Tier prices are used to provide discounts for products based on quantity. For example, you could set a tier price that allows customers to buy two products for X amount each.

The tier price is used when a developer wants to offer a discount based on the quantity purchased. For example, buying two or more units of a product at a reduced price per unit. Tier pricing allows setting different prices for different quantities, encouraging customers to buy more. Special price is a flat discounted price regardless of quantity, and group price is used to set special prices for specific customer groups, not for quantity-based discounts.

After a thorough search of the provided documents, I couldn't find a direct reference to the specific CLI command for determining if static content signing is enabled in Magento. However, the typical command for checking configuration settings in Magento isbin/magento config:show <path>, where<path>is the configuration path for the setting you wish to view. Based on Magento's configuration path patterns and the options provided, the most logical choice would beB. bin/magento config:show dev/static/sign, although this cannot be confirmed without further context or documentation.

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 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 add a custom router class to the list of routers in Magento, theroutes.xmlfile is used. This file should be located in theetcdirectory of the module, under the appropriate area (eitherfrontendoradminhtml). Within theroutes.xmlfile, you define a router with an ID, a route with an ID and frontName, and specify the module that the route corresponds to. This setup allows Magento to recognize and utilize the custom router when processing URLs, directing requests to the appropriate controllers based on the custom routing logic defined??.

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.

If a developer fails to mention the start date in the "From" field when creating a price rule, the price rule will be saved. However, the price rule will not go into effect until the start date is added.

If a developer fails to mention the start date in the "From" field when creating a price rule in Adobe Commerce, the system will default to the current date, and the price rule will go into effect as soon as it is saved. The absence of a start date means there is no delay in the activation of the rule, and it becomes effective immediately upon saving.

In Magento, plugins (Interceptors) can only intercept public methods. This is because the plugin system relies on Magento's object manager to dynamically create proxy classes that can intercept method calls. Since private and final methods are not accessible from outside the class they are defined in, and static methods are not called on an object instance, these method types cannot be intercepted. This mechanism allows for the extension and customization of Magento's core behavior in a transparent and non-intrusive manner??.

On an Adobe Commerce Cloud project, a custom patch should be placed in them2-hotfixes/directory to have it automatically applied during the build phase. The patches in this directory are applied in alphabetical order and can be used to apply quick fixes to the code that will be included in the build artifact.

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??.

To add an image icon in front of the telephone field in the shipping address form on the checkout page, the correct way is to modify the UI component by setting a custom template file for the field. The snippet in option B is the correct one because it uses the<block>element and sets theelementTmplto the custom template path within theargumentsnode under theconfignode. This modification will instruct Magento to use the specified custom template file for rendering the telephone field, allowing for the addition of an image icon in front of it.

The customer data JS library is used to store private customer data in local storage. This data can be used to improve the customer's experience on the store, such as by remembering their shipping address or their preferred payment method.

The customer data JS library in Adobe Commerce is used for managing customer data on the client side, such as the shopping cart, comparison list, and wishlist. It does not store sensitive information like credit card details or usernames and passwords. Instead, it utilizes local storage to keep a private data section where customer-specific data is stored securely and accessed via JavaScript, making option B correct.

A developer can prioritize the execution of a plugin by using thesortOrderproperty within the plugin's declaration in thedi.xmlfile. Specifying a lower value for thesortOrderproperty gives the plugin higher priority, meaning it will be executed before other plugins with a higher sortOrder value. This allows developers to control the order of plugin execution, which can be critical for ensuring the desired outcome when multiple plugins are affecting the same method??.

In Magento, the default store ID for the admin panel is 0. This is used as a fallback mechanism where, if the current store view's ID is not 0, Magento automatically adds 0 as a fallback. This ensures that the admin panel has a unique identifier, differentiating it from the frontend store views, which typically start with IDs higher than 0. This setup is crucial for Magento's multi-store architecture, allowing for distinct configurations and behaviors between the admin and frontend contexts??.

• A quote is a temporary object that represents the customer’s shopping cart before it is converted into an order1. A quote can be created by a guest or a registered customer, and it can be active or inactive depending on whether the customer has completed the checkout process or not2.
• The quote table stores the basic information about the quote, such as the customer ID, email, currency, subtotal, grand total, shipping method, payment method, and so on2. Each row in the quote table corresponds to one quote object, identified by a unique entity ID2.
• The quote item table stores the details of each product added to the quote, such as the product ID, SKU, name, price, quantity, discount amount, tax amount, and so on2. Each row in the quote item table corresponds to one quote item object, identified by a unique item ID2. A quote item object is associated with a quote object by the quote ID column in the quote item table2.
• When a customer adds a product to the cart, Magento creates or updates a quote object and a quote item object for that product. The quote object is initialized by the Magento\Quote\Model\Quote class, which implements the Magento\Quote\Api\Data\CartInterface interface3. The quote item object is initialized by the Magento\Quote\Model\Quote\Item class, which implements the Magento\Quote\Api\Data\CartItemInterface interface3.
• Magento uses various classes and interfaces to manipulate the quote and quote item objects, such as the Magento\Quote\Model\QuoteRepository class, which implements the Magento\Quote\Api\CartRepositoryInterface interface for saving and retrieving quotes from the database3, and the Magento\Quote\Model\QuoteManagement class, which implements the Magento\Quote\Api\CartManagementInterface interface for creating and submitting quotes to orders3.
• Magento also uses various events and observers to perform additional actions on the quote and quote item objects, such as applying discounts, calculating taxes, validating stock availability, and so on. Some of these events are: sales_quote_add_item, sales_quote_collect_totals_before, sales_quote_collect_totals_after, sales_quote_save_before, sales_quote_save_after, sales_model_service_quote_submit_before, sales_model_service_quote_submit_after.
• Magento provides various APIs for interacting with the quote and quote item objects, such as the Magento\Quote\Api\CartManagementInterface API for creating empty carts and placing orders from carts, the Magento\Quote\Api\CartItemRepositoryInterface API for adding, updating, and removing items from carts, and the Magento\Quote\Api\CouponManagementInterface API for managing coupons for carts.

The two attribute input types that can be used for a date are Date and Time and Date. These input types allow the user to select a date or a date and time from a calendar widget.

The Timezone and Schedule input types do not exist in Adobe Commerce.

In Magento, attribute input types define the type of data an attribute can hold and how it should be inputted or displayed in the UI. For dates, Magento provides specific input types to handle date-related data efficiently. The "Date" input type is used for attributes that require only a date, without a time component, suitable for birthdays, anniversaries, or any date-specific information. The "Date and Time" input type, on the other hand, includes both date and time components, ideal for events, promotions, or any scenario where the time of day is relevant. These input types ensure data consistency and provide a user-friendly interface for selecting dates and times.

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.

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.
