a. The code that is commonly repeated is as follows:

The Architect needs to recommend an optimal solution to avoid redundant dependency and duplicate code among the methods. Which solution should the Architect recommend?

Show Suggested Answer Hide Answer
Suggested Answer: B

The Architect should recommend replacing all VendorPaymentModuleGatewayConfigConfig Classes with virtualType of MagentoPaymentGatewayConfigConfig and setting <user_secret backend_Model=''MagentoConfigModelConfigBackendEncrypted'' /> under config.xml. This will avoid redundant dependency and duplicate code among the methods. The virtualType of MagentoPaymentGatewayConfigConfig will inherit the functionality of the base class and allow the customization of the constructor arguments, such as the pathPattern and valueHandlerPool.The backend_Model attribute of the user_secret field will specify that the value of this field should be encrypted and decrypted by the MagentoConfigModelConfigBackendEncrypted class, which implements the MagentoFrameworkAppConfigValueInterface interface and uses the MagentoFrameworkEncryptionEncryptorInterface internally12.This way, the payment modules do not need to depend on the MagentoFrameworkEncryptionEncryptorInterface or the MagentoFrameworkAppConfigScopeConfigInterface directly, and can use the getValue method of the MagentoPaymentGatewayConfigConfig class to get the decrypted value of the user_secret field3.Reference:
