AD0-E722 Practice Test

Explanation:

Developer mode is the best option for setting up a development environment for testing functionality, not performance, before being passed to the testing team. In developer mode:

Errors are logged and hidden from the user. This ensures that the user does not see any uncaught exceptions or debugging information, but the developers can still access them from the log files.

Cache mode can only be changed from command line. This prevents any accidental or unauthorized changes to the cache settings from the admin panel or other sources. Static files are created dynamically and then cached. This allows the developers to see the latest changes to the static files without having to run the static content deployment command every time. The static files are also cached for faster loading.

Explanation:

To add a product type with custom pricing, the Architect needs to do the following steps:

Create a content of the etc/product_types.xml file that defines the new product type, its label, model, index priority, and price model. This file is used to register the new product type and its associated classes in Magento1.

Create a new price model that extends \Magento\Catalog\Model\Product\Type\Price and implements the custom pricing logic for the new product type. The price model is responsible for calculating the final price of the product based on various factors, such as special price, tier price, catalog price rules, etc2.

Create a custom type model that extends from the abstract Product Type model (\Magento\Catalog\Model\Product\Type\AbstractType) and overrides the methods related to the product type behavior, such as prepareForCart, getAssociatedProducts, etc. The type model defines how the product type interacts with other components, such as quote, order, cart, etc3.

Explanation:

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.
