BEST Verified Adobe AD0-E716 Exam Questions (2026) [Q26-Q45]

NO.26 An Adobe Commerce developer wants to generate a list of products using ProductRepositorylnterf ace and search for products using a supplier_id filter for data that is stored in a standalone table (i.e., not in an EAV attribute).
Keeping maintainability in mind, how can the developer add the supplier ID to the search?

Write a before plugin on HagentocatalogVtodelProductRepository: :geti_ist() and register the search criteria passed. Write an event observer to 0 listen for the event cataiog_product_coiiection_ioad_before. Iterate through the registered search criteria, and if found, apply the needed join and filter to the events scollection.

Add a CUStOm filter to the Virtual type
“agentoCatalogModelApiSearchCriteriaCollectionProcessorProductFilterProce5sor for supplier_id field. In the custom filter, apply the needed join and filter to the passed $collection.

Write a before plugin On MagentoFrameworkApiSearchCriteriaCollectionProcessorInterface: :
process(). Iterate through the $searchCriteria
provided for supplier_id, and if found, apply the needed join and filter to the passed scollection.

The developer can add a custom filter to the virtual type
Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\ProductFilterProce5sor for supplier_id field.
In the custom filter, the developer can apply the needed join and filter to the passed $collection. This is the recommended way to extend the search criteria for products using dependency injection and plugins. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange] In Adobe Commerce, when you need to add a custom filter for a non-EAV attribute stored in a standalone table, the most maintainable approach is to create a custom filter for ProductFilterProcessor. This processor allows for customized search criteria handling, which can be extended to include custom joins and filters without altering core functionality or relying on plugins and observers.
* Why Custom Filter in ProductFilterProcessor is Preferred:
* The ProductFilterProcessor within SearchCriteria\CollectionProcessor is specifically designed to handle filtering of product collections. By extending this with a custom filter, the developer can implement joins and filters on standalone tables.
* This approach is modular and reusable, allowing any code that utilizes ProductRepositoryInterface to apply the supplier_id filter seamlessly.
* Implementation of Custom Filter:
* Define a custom filter class that implements the required logic to join the standalone table and apply the supplier_id filter.
* Register this custom filter with a virtual type in di.xml for ProductFilterProcessor, so it can process the supplier_id as part of the search criteria.
* Why Options A and C are Less Suitable:
* Option A relies on an event observer, which is less modular and may have performance implications since it requires listening to every product collection load event.
* Option C, while functional, involves modifying CollectionProcessorInterface::process(), which is more generic and not specifically tailored for product collection filtering.
* References:
* Magento Developer Documentation on Using Custom Filters in CollectionProcessor
* Magento DevDocs on Dependency Injection and Virtual Types

NO.28 An Adobe Commerce developer is asked to implement a 15% surcharge for all users from a ‘Wholesale’ customer group. Keeping best practices in mind, what is a correct to accomplish this?

Declare a new total collector class to calculate the modified total if the current user is in the group, register it in the module’s etc/sales .xml file, modify the checkout_cart_index.xml and checkout_index_index.xml layouts to include a new child in the totals block.

Create a Cart Price Rule that applies only to the ‘Wholesale’ group. Specify no conditions for the rule, and in the Actions section, specify for the rule to apply a “Percent of product price discount”, with the ‘Discount Amount” field set to -15.

Create an Observer to the cataiog_product_get_final_price event. Check if the current customer is in the ‘Wholesale’ group, and if so, retrieve the

NO.29 An Adobe Commerce developer has installed a module from a third-party vendor. This module fires a custom event named third_party_event_after and also defines an observer named third_party_event_after_observer that listens to that event. The developer wants to listen to this custom event in their own module but wants to execute their observer’s logic after the third_party_event_after_observer observer has finished executing.
What would the developer do to ensure their observer runs after the observer defined by the third-party module?

Ensure the third-party module is listed in the <sequence> node of the developer’s module.xmi file.

Set the sort order of the new observer to be less than that of the third-party vendor’s observer.

This is not possible as observers listening to the same event may be invoked in any order.

NO.44 An Adobe Commerce developer is working on a custom gallery extension.
The module uses the MagentocatalogModeliinageUploader class for image uploading. The admin controller for custom image uploads is VendorCustomGalleryControllerAdminhtmlImageUpload.
The images need to be stored in different basePath and baseTmpPath than the default ones.
How can the default imageuploader class be extended and used without affecting the other modules that are already using it?

To extend the Magento\Catalog\Model\ImageUploader class and configure it with custom basePath and baseTmpPath without affecting other modules that utilize this class, the best approach is to use a Virtual Type
. Virtual types allow you to create a customized version of a class for a specific context without altering the original class or its usage elsewhere.
Option A is correct for the following reasons:
* Creating a Virtual Type:By defining a virtual type (Vendor\CustomGallery\GalleryImageUpload) in the di.xml, you create a custom version of the ImageUploader class. This virtual type can have unique configurations for basePath and baseTmpPath, which are specific to the custom gallery module.
* Explanation: Virtual types are particularly useful in Magento when you need to use a slightly modified version of an existing class in a specific context. In this case, the virtual type allows you to define custom paths without altering the base ImageUploader class, ensuring that other modules using ImageUploader are unaffected.
* References: Magento’s developer documentation on dependency injection and virtual types highlights this pattern for customizing class behavior in a contained and non-intrusive manner.
* Injecting the Virtual Type into the Admin Controller:The custom virtual type is then injected into the Vendor\CustomGallery\Controller\Adminhtml\Image\Upload controller. This ensures that only this controller uses the modified version with the custom paths, leaving other instances of ImageUploader to function with their default settings.
* Explanation: By explicitly injecting the virtual type into the controller, you localize the configuration changes to only the desired functionality. This approach is efficient and maintains module independence, a key principle in Magento development.
Options B and C are incorrect for the following reasons:
* Option B directly modifies Magento\Catalog\Model\ImageUploader with the new paths. This change will affect all usages of the ImageUploader class across the site, which contradicts the requirement to avoid impacting other modules.
* Option C involves creating a virtual type and then setting it as a preference. However, using a preference would replace all instances of ImageUploader across the entire Magento application, leading to the same issue as Option B.

NO.45 An Adobe Commerce developer is asked to change the tracking level on a custom module for free downloading of pdf and images.
The module contains following models:
Download class has a parameter for tracking_level.
How will the developer configure the tracking_level parameter, in di.xml.to have a value of 4 for Download class and all classes that extend Download?
