How should a developer display a custom attribute on the category edit page in the admin panel when a new module Vendor.Category is created?
Correct Answer:C
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 a category_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

Which two attribute input types can be used for a date? (Choose two.)
Correct Answer:CD
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. Verified References: [Adobe Commerce User Guide - Create a product attribute]
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.
An international merchant is complaining that changes are taking too long to be reflected on the frontend after a full product import.
Thinking it may be database issues, the Adobe Commerce developer collects the following entity counts:
• Categories: 900
• Products: 300k
• Customers: 700k
• Customer groups : 106
• Orders: 1600k
• Invoices: 500k
• Creditmemos: 50k
• Websites : 15
• Stores : 45
What is a probable cause for this?
Correct Answer:A
The combination of a large number of products, categories, and stores directly affects the flat catalog indexing process. Each product needs to be indexed across all categories and stores, which exponentially increases the data size of the index tables. This can significantly slow down the frontend updates after a full product import due to the high volume of data that needs to be processed.
Impact on Flat Catalog and Indexing:
In Magento, flat catalog tables are used to optimize product data retrieval, especially in stores with a large catalog. However, with high numbers of products, categories, and stores, the flat catalog tables become massive, making them slower to update.
In this scenario, the system must create and maintain an entry for each product in each store across every category, leading to a substantial volume of data.
Why Option A is Correct:
This combination (products, categories, stores) is known to cause performance issues in indexing and data storage. It impacts the catalog indexes, which are critical for reflecting updates on the frontend.
Options B and C do not directly relate to the delay after product imports. Option B involves customer-related data, and Option C is related to price indexing, which affects a different area.
Optimization Recommendations:
Consider disabling the flat catalog and leveraging Elasticsearch for product and category search and filtering. Additionally, increasing server resources or partitioning the data could help optimize performance.

An Adobe Commerce developer has been tasked with applying a pricing adjustment to products on the website. The adjustments come from a database table. In this case, catalog price rules do not work. They created a plugin for getPrice on the price model, but the layered navigation is still displaying the old price.
How can this be resolved?
Correct Answer:C
The developer can resolve this issue by creating a plugin for theMagento\Catalog\Model\Indexer\Product\Price::executeRow()method. This method is responsible for updating the product price index.
The plugin can be used to add the pricing adjustment from the database to the product price index. Once the product price index is updated, the layered navigation will display the correct price.
Here is an example of a plugin for theexecuteRow()method: PHP
class MyPlugin
{
public function executeRow(
\Magento\Catalog\Model\Indexer\Product\Price $subject,
\Magento\Catalog\Model\Product $product, array $data
) {
$adjustment = $this->getAdjustment($product);
$product->setPrice($product->getPrice() + $adjustment);
}
private function getAdjustment(Product $product)
{
$adjustment = $product->getData('adjustment');
if (!is_numeric($adjustment)) { return 0;
}
return $adjustment;
}
}
This plugin will add theadjustmentdata from the product to the product price index. Once the product price index is updated, the layered navigation will display the correct price.
Which attribute option restricts Catalog EAV attributes to only certain product types?
Correct Answer:B
Theapply_toattribute option in Magento's Catalog EAV model restricts the use of certain attributes to specific product types. By specifying product types in the
apply_tofield, developers can control which attributes are applicable to which types of products, ensuring that attributes are only available where they are relevant and meaningful.
