Adobe AD0-E716 Adobe Commerce Developer with Cloud Add-on Exam Practice Test

 The steps necessary prior to redeploying in order to upgrade to Enhanced Integration Environments are to limit the number of integration branches to two and to submit a support ticket requesting the upgrade. Enhanced Integration Environments are an improved version of integration environments that offer better performance, stability, and security. They have a limit of four active branches at a time, but only two branches can be migrated from standard integration environments. The developer needs to delete or deactivate any extra branches before requesting the upgrade from Adobe support. Verified References: [Magento 2.4 DevDocs]

Some of the features provided by ECE-Tools are building application, applying custom patches, and dumping configuration for static content deployment. ECE-Tools is a set of scripts and tools designed to manage and deploy Adobe Commerce Cloud projects. It provides commands for building application code, applying patches for Magento core issues or custom modules, and dumping configuration settings for static content deployment optimization.

The developer can test the new feature under the integration environment by deactivating one of the active integration environment branches, creating a new active branch from integration and installing the module, and pushing the changes. This is because Enhanced Integration Environments have a limit of four active branches at a time, and each branch has its own dedicated database and services. The developer can use the Cloud CLI for Commerce tool to manage the branches and deploy the code changes.

The developer can fix this issue by increasing the disk space of the database service. The database service is one of the services that run on the Adobe Commerce Cloud platform and provide functionality for the application. The database service uses MySQL as the database engine and stores data for products, customers, orders, etc. The disk space of the database service determines how much data can be stored and processed by the database. If the disk space is insufficient, the database import can fail with a disk space error. The developer can increase the disk space of the database service by modifying the .magento/services.yaml file and redeploying the environment. Verified References: [Magento 2.4 DevDocs]

According to the How to use the Magento command-line interface (CLI) guide, to configure and run the Magento CLI, the developer needs to make the bin/magento file executable and then use it to run commands. To create a custom command, the developer needs to create a class that implements \Symfony\Component\Console\Command\Command and define its name, description, arguments, options, and logic. The developer also needs to register the command in the di.xml file of their module using the Magento\Framework\Console\CommandList argument. Therefore, option C is the correct answer, as it shows the correct class and di.xml code to configure the custom command.

To store a block in the system cache, the developer needs to set values for both thecache_lifetimeandcache_keydata properties of the block. Thecache_lifetimeproperty specifies how long the block should be cached, and thecache_keyproperty specifies a unique identifier for the block.

The following code shows how to set thecache_lifetimeandcache_keydata properties of a block:

PHP

$block->setData('cache_lifetime', 600);

$block->setData('cache_key', 'my_custom_block');

Once thecache_lifetimeandcache_keydata properties have been set, the block will be stored in the system cache and will not be regenerated on each page load.

According to the Develop data and schema patches guide for Magento 2 developers, data patches can also implement PatchRevertabieinterface to provide rollback functionality for their changes. The revert() method contains the instructions to undo the data modifications made by the patch. To ensure that the product attribute is removed when the module is uninstalled, the developer should make the data patch implement PatchRevertabieinterface and implement the revert method to remove the product attribute using EavSetupFactory or AttributeRepositoryInterface.

To ensure the developer has access to push code in an Adobe Commerce Cloud project, the developer’s email must be added under Users in the Cloud Project Web UI and the developer needs to add SSH public key in the Cloud Account dashboard settings. The Cloud Project Web UI is a web interface that allows managing and configuring Adobe Commerce Cloud projects and environments. The developer’s email must be added under Users to grant them access to the project and assign them a role and permissions. The Cloud Account dashboard settings is a web interface that allows managing and configuring Adobe Commerce Cloud accounts and SSH keys. The developer needs to add SSH public key in the settings to enable secure connection to the project and environments via SSH. Verified References: [Magento 2.4 DevDocs]

Decreasing the batch size value improves performance by reducing the memory usage for the temporary table. The batch size value determines how many rows of data are processed at a time by the indexer. A large batch size value can cause the allocated memory size for the temporary table to exceed 20% of innodb_buffer_pool_size, which can result in errors and slow down the indexing process. By lowering the batch size value, the indexer can process the data more efficiently and avoid memory issues. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange]

The developer can enable the magnification of CSS files on an Adobe Commerce Cloud Staging environment by locally running the command bin/magento config:set --lock-config dev/css/minify_files 1 from the command line. This will set the configuration value in the app/etc/config.php file and lock it from being changed in the Admin Panel. The developer then needs to commit the app/etc/config.php file and redeploy the environment. Verified References: [Magento 2.4 DevDocs] 2

The developer can deal with this issue by modifying the admin path timeout value in seconds in the Fastly Configuration section > Advanced Configuration in the Admin Panel. Fastly is a cloud-based caching service that improves site performance and security for Adobe Commerce Cloud projects. Fastly has a default timeout value of 180 seconds for admin requests, which means that any request that takes longer than 180 seconds will be terminated and result in a timeout error. The developer can increase this value to allow longer processing time for admin requests without causing errors. The developer also needs to save the configuration and upload VCL to Fastly to apply the changes. Verified References: [Magento 2.4 DevDocs]

According to the Develop data and schema patches guide for Magento 2 developers, data patches are classes that contain data modification instructions. They are defined in a //Setup/Patch/Data/.php file and implement MagentoFrameworkSetupPatchDataPatchInterface. Data patches can also implement Patchversioninterface to specify the module version that the patch is associated with. The getVersion() method returns the module version as a string. To skip changes that were already applied via old format (install/upgrade scripts), the developer should implement Patchversioninterface and return 1.5.4 on the getVersion() method. This way, the data patch will only be applied if the module version is greater than or equal to 1.5.4.

The variable env: composer_auth is located in the Project variables section in the Project Web Interface. This variable is used to store the authentication credentials for Composer repositories that require access keys or tokens. The developer can set this variable at the project level to apply it to all environments, or override it at the environment level if needed.

The following XML will allow the new content type to be a child of slider content types:

slider

improved_slide

Use code with caution. 

This XML will tell Magento that theslidercontent type can haveimproved_slidecontent types as children.

The developer can use the canInvoice method of the order object to check if the order can be invoiced or not. This method returns true if the order has a state of new, processing, or payment review and has not been fully invoiced yet. The developer can use this method in a conditional statement to send the order ID to the ERP system only if the order can be invoiced.

The shipping method would display $10 and customers would pay $10 for using the new shipping method. This is because the collectRates method sets the price and cost of the shipping method to 10 in the result object. The price is what is shown to the customer on thefrontend and the cost is what is charged to the customer when they place the order. The handling fee is not used in this case because it is set to zero in the config.xml file. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange]

Two ways to access the PHP error logs on Adobe Commerce Cloud are to use the dedicated command from Cloud CLI for Commerce and to connect to the servers via SSH and localize the log files. The Cloud CLI for Commerce is a command-line tool that allows developers to interact with their Adobe Commerce Cloud projects and environments. The developer can use the command magento-cloud log php to view or download the PHP error logs from any environment. Alternatively, the developer can connect to the servers via SSH and navigate to the var/log directory where the PHP error logs are stored.

The CLI command that the developer would use to update the admin url is magento-cloud variable:set ADMIN_URL. This command sets an environment variable called ADMIN_URL with a custom value for the admin url on a specific environment. Environment variables are configuration settings that affect the behavior of the Adobe Commerce Cloud application and services. By setting an environment variable for ADMIN_URL, the developer can change the default admin url to a unique url for every branch/environment of their Adobe Commerce Cloud project.

The reason why there are records remaining in the inventory_reservation table is that only reservations no longer needed are removed by the cron job. The inventory_reservation table tracks the quantity of each product in each order and creates a reservation for each product when an order is placed, shipped, cancelled or refunded. The initial reservation has a negative quantity value and the subsequent reservations have positive values. When the order is complete, the sum of all reservations for the product is zero. The cron job removes only those reservations that have a zero sum from the table, leaving behind any reservations that are still needed for incomplete orders.
