A developer has created the backend models for a new payment method. To make this method appear as an option on the checkout page, it must be declared to the system. Which XML file is specifically use

Question

Options

• A'etc/frontend/di.xml'
• B'etc/payment.xml'
• C'etc/sales.xml'
• D'etc/config.xml'

• A
  5% (1)
• B
  84% (16)
• C
  11% (2)

Explanation

In Magento 2, etc/payment.xml is the dedicated configuration file for declaring payment methods - it registers the method with the payment system, making it available as a checkout option and associating it with the corresponding models.

Why the distractors are wrong:

• A (etc/frontend/di.xml) - di.xml handles dependency injection and class preferences/plugins, not payment method registration; frontend/ scoping just limits it to the frontend area.
• C (etc/sales.xml) - sales.xml configures sales-related settings like order statuses and totals, not payment method declarations.
• D (etc/config.xml) - config.xml provides default configuration values (like default store settings), but it doesn't register payment methods with the system.

Memory tip: Think of payment.xml as the "menu registration" file - just like a new item must be added to a restaurant menu before customers can order it, a new payment method must be declared in payment.xml before shoppers can select it at checkout.
