What are two mandatory files needed to register a custom module? (Choose two.)

Question

Options

• Aregistration.xml
• Bregister.php
• Cetc/module.xml
• Dregistration.php

• A
  5% (1)
• B
  5% (1)
• C
  90% (19)

Explanation

In Magento 2, every custom module requires etc/module.xml (C) to declare the module's name and sequence/dependencies, and registration.php (D) to register the module with Magento's component registry using \Magento\Framework\Component\ComponentRegistrar::register(). Without both files, Magento will not recognize or load the module.

Why the distractors are wrong:

• A. registration.xml - This file does not exist in Magento 2's module system; it's a fabricated distractor.
• B. register.php - The correct filename is registration.php (with the full word "registration"); register.php is not a valid Magento file.

Memory tip: Think of it as a two-step handshake - registration.php introduces the module to Magento's autoloader, while etc/module.xml describes it (name, version, load order). No introduction + no description = no module.
