AD0-E722 Exam Dumps : Adobe Commerce Architect Master

• Option A is correct because enabling the config flag under deployment/blue_green/enabled is one of the steps to ensure zero downtime during the deployment process of Magento 2 on-premises. This flag enables the blue-green deployment feature, which allows deploying a new version of the Magento application to a separate environment (blue) without affecting the current live environment (green). Once the new version is ready, the traffic can be switched from green to blue with minimal or no downtime1.
• Option C is correct because running bin/magento setup:upgrade --keep-generated is another step to ensure zero downtime during the deployment process of Magento 2 on-premises. This command updates the database schema and data without deleting the generated code and static view files. This way, the Magento application can still serve requests from the cache while the database is being upgraded2.
• Option B is incorrect because running bin/magento setup:upgrade --dry-run=true does not upgrade the database, but only checks if there are any errors or conflicts in the database schema or data. This command can be used for testing purposes, but it does not affect the deployment process or the downtime3.
• Option D is incorrect because there is no such option as --convert-old-scripts-true for the bin/magento setup:upgrade command. This option does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.
• Option E is incorrect because there is no such config flag as developer/zero_down_time/enabled in Magento 2. This flag does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.

The product price index can be optimized by using parallel mode and customer group merging. Parallel mode allows the indexer to run multiple threads simultaneously, which can speed up the indexing process. Customer group merging reduces the number of rows in the price index table by merging customer groups that have the same product prices. This can improve the performance of the price index queries and reduce the index size. References: Indexing optimization, Price index customer group merging

Option C is the correct solution because declaring a capture command with type Magento\Payment\Gateway\Command\NullCommand for the payment method command pool in di.xml will prevent the default capture logic from being executed. The NullCommand class is a dummy implementation of the CommandInterface that does nothing. This way, the payment capture will be handled by the PSP webhook, and the invoice will be created accordingly12

Option A is not a correct solution because adding a plugin before the $invoice->capture() and changing its input to prevent the call of the $payment->capture() will require modifying the core Magento code, which is not recommended. Moreover, this solution will affect all payment methods that use the invoice capture logic, not just the monthly installments payment extension3

Option B is not a correct solution because changing the can_capture attribute for the payment method under config.xml to be 0 will disable the capture functionality for the payment method entirely. This means that the invoice cannot be created or captured, even by the PSP webhook4
