An Architect is investigating a merchant's Adobe Commerce production environment where all customer session data is randomly being lost. Customer session data has been configured to be persisted using Redis, as are all caches (except full page cache, which is handled via Varnish).
After an initial review, the Architect is able to replicate the loss of customer session data by flushing the Magento cache storage, either via the Adobe Commerce Admin Panel or running bin/magento cache: flush on the command line. Refreshing all the caches in the Adobe Commerce Admin Panel or running bin/magento cache: clean on the command line does not cause session data to be lost.
What should be the next step?
A representative of a small business needs an Adobe Commerce Architect to design a custom integration of a third-party payment solution. They want to reduce the list of controls identified in their Self-Assessment Questionnaire as much as possible to achieve PCI compliance for their existing Magento application.
Which approach meets the business needs?
An Adobe Commerce Architect creates a stopword for the Italian locale named stopwordsjtJT.csv and changes the stopword directory to the following:
What is the correct approach to change the stopwords directory inside the custom module?
According to the Adobe Commerce documentation, the correct approach to change the stopwords directory inside a custom module is to use dependency injection to override the default values of the stopwordsDirectory and stopwordsModule parameters of the \Magento\Elasticsearch\SearchAdapter\Query\Preprocessor\Stopwords class. The stopwordsDirectory parameter specifies the relative path of the stopwords directory from the module directory, while the stopwordsModule parameter specifies the name of the module that contains the stopwords directory. By adding these parameters to the di.xml file of the custom module, the Architect can change the location of the stopwords files without modifying the core code or database.
While developing a new functionality for a website in developer mode with all cache types enabled, an Adobe Commerce Developer needs to add \Magento\Sales\Model\Service\InvoiceService SinvoiceService as a new dependency to an existing page action controller in Vendor\CustomModule\Controller\Index\Index . This is accomplished as follows:
After cleaning the f ull_page cache and reloading the page, the developer encounters the following exception:
Recoverable Error: Argument 2 passed to Vendor\CustomModule\Controller\Index\Index::__construct() must be an instance of
\Magento\Sales\Model\Service\InvoiceService [...]
Which action should the Architect recommend to the developer to fix this error?
The error is caused by the generated child class not being updated with the new dependency. Removing the generated child class will allow the system to generate a new child class with the correct dependency. The generated child class is a proxy class that extends the original controller class and overrides the constructor to inject the dependencies using the object manager. The generated child class is created when the system runs in developer mode with cache enabled, to avoid performance issues. However, when a new dependency is added to the original controller class, the generated child class does not reflect the change and causes a mismatch in the constructor arguments. Therefore, deleting the generated child class from the generated/code directory will solve the problem.

A merchant notices that product price changes do not update on the storefront.
The index management page in the Adobe Commerce Admin Panel shows the following:
* All indexes are set to 'update by schedule'
* Their status is 'ready'
* There are no items in the backlog
* The indexes were last updated 1 minute ago
A developer verifies that updating and saving product prices adds the relevant product IDs into the catalog_product_price_cl changelog table. Which two steps should the Architect recommend to the developer to resolve this issue? (Choose two.)
