When using multiple backend servers behind a load balancer, the session data must be stored in a shared location that is accessible by all servers. Otherwise, the session data will be inconsistent and users may experience issues such as being logged out unexpectedly. Redis is a recommended option for storing session data in a distributed architecture, as it provides fast and reliable access to the data. The session host value in the env.php file must point to the Redis instance that is used for session storage. References:

Based on web searches, it seems that Magento uses different classes and interfaces to interact with configuration files, such as Data, Reader, and Converter12.

According to the documentation1, Data is a class that provides access to configuration data using a scope. Reader is an interface that reads configuration data from XML files. Converter is an interface that converts XML data into an array representation.

Based on these definitions, I would say that two possible steps that the Architect should make to meet the requirement are:

• C. Create a Data class that implements “\Magento\Framework\Config\Data”
• E. Make a Reader class that implements “\Magento\Framework\Config\Reader\Filesystem”

These steps would allow the custom module to read all the XML configuration files declared in the system, merge them together, and use their values in PHP class.

The Architect should make two steps to meet this requirement: C) Create a Data class that implements “\Magento\Framework\Config\Data”. This class will be responsible for reading and merging the custom xml configuration files and providing access to their values. The Data class should extend \Magento\Framework\Config\Data and use the constructor to inject the Reader class and the cache type. E) Make a Reader class that implements “\Magento\Framework\Config\Reader\Filesystem”. This class will be responsible for loading and validating the custom xml configuration files from different modules. The Reader class should extend \Magento\Framework\Config\Reader\Filesystem and use the constructor to specify the file name, schema file, and validation state of the custom xml configuration files. Option A is incorrect because writing a plugin for \Magento\Framework\Config\Data::get() will not define a new xml configuration file, but rather modify the existing one. Option B is incorrect because appending the custom xml file name in “Magento\Config\Model\Config\Structure\Reader” in di.xml will not define a new xml configuration file, but rather add it to the system configuration structure. Option D is incorrect because injecting a “reader” dependency for “Magento\Framework\Config\Data” in di.xml will not define a new xml configuration file, but rather use an existing one. References:

The Architect should utilize the payment provider iframe system to isolate content of the embedded frame from the parent web page. This approach will reduce the list of controls identified in their Self-Assessment Questionnaire as much as possible to achieve PCI compliance for their existing Magento application. By using an iframe, the payment provider handles all customer-sensitive data and Magento does not store or process any cardholder data. This reduces the PCI scope and simplifies the compliance process. Option B is incorrect because utilizing the Advanced Encryption Standard (AES-256) algorithm to encrypt all customer-sensitive data from the payment module will not reduce the PCI scope, but rather increase it. Magento will still store and process cardholder data, which requires more controls and validation. Option C is incorrect because utilizing a trusted signed certificate issued by a Certification Authority (CA) to secure each connection made by the payment solution protocol via HTTPS will not reduce the PCI scope, but rather ensure the security of data transmission. Magento will still store and process cardholder data, which requires more controls and validation. References:
