Question 1

An Adobe Commerce Architect gets a request to change existing payment gateway functionality by allowing voided transactions only for a certain range of paid amounts.

In the vendor module file etc/config.xml, payment method has an option can,_void set to 1.

How should this customization be done?



Answer : C

The Architect should add a new handler with name can_void to virtualType based on type Magento\Payment\Gateway\Config\ValueHandlerPool in payment method facade configuration. This handler will be responsible for determining whether the payment method can void transactions or not, based on the custom logic of the paid amount range. The handler should implement \Magento\Payment\Gateway\Config\ValueHandlerInterface and override the handle() method to return true or false depending on the payment amount. Option A is incorrect because extending Magento\Payment\Model\Method\Adapter and reimplementing method void will not change the can_void option, but rather the logic of voiding transactions. Option B is incorrect because declaring a new plugin for class Magento\Payment\Gateway\Config\ConfigValueHandler and using the afterHandle method will affect all payment methods that use this class, not just the specific one that needs customization.

Question 2

An Architect working on a headless Adobe Commerce project creates a new customer attribute named my_attribure. Based on the attribute value of the customer, the results of GraphQI queries are modified using a plugin. The frontend application is communicating with Adobe Commerce through Varnish by Fastly, which is already caching the queries that will be modified. The Adobe Commerce Fastly extension is installed, and no other modifications are made to the application.

Which steps should the Architect take to make sure the vcl_hash function of Varnish also considers the newly created attribute?

A)

B)

C)



Answer : B

Option B is the correct way to make sure the vcl_hash function of Varnish also considers the newly created attribute. The Architect should create a new module that depends on Magento_Fastly and declare a plugin for \Magento\Fastly\Model\Config::getVclSnippets() method. The plugin should add a new snippet to the result array with the type 'recv' and the content 'set req.http.my_attribute = req.http.X-Magento-Vary;'. This will append the value of the customer attribute to the hash key used by Varnish for caching. Option A is incorrect because it modifies the core file of Magento_Fastly module, which is not recommended and can cause issues during upgrades. Option C is incorrect because it uses the wrong type and content for the snippet, which will not affect the vcl_hash function. Reference: https://devdocs.magento.com/cloud/cdn/fastly-vcl-bypass-to-origin.html

According to the Adobe Commerce Developer Guide2, to make sure the vcl_hash function of Varnish also considers the newly created attribute, the Architect should use a plugin for Magento\Customer\Model\Context::getVaryString method and add the attribute value to the vary string. This will ensure that Varnish caches different versions of GraphQL queries based on the attribute value of the customer. Therefore, option B is correct. Option A is not correct because it does not affect the vcl_hash function. Option C is not correct because it does not use a plugin for the getVaryString method.


Question 3

A company has an Adobe Commerce store. An attribute named "my.attribute" (type "text") is created to save each product's global ID that is shared between multiple systems.

Several months after going live, the values of "my.attribute" are all integer. This causes a problem for the other systems when those systems receive this data.

An Adobe Commerce Architect needs to recommend a solution to change the type of "my.attribute" from textXo int

Which two steps should the Architect take to achieve this? (Choose two.)



Answer : A, D

Option A is correct because it will migrate data from one table to another based on the attribute id, which is required when changing the attribute type14.Option D is correct because it will create a data patch that will update 'my.attribute' type from ''text'' to ''int'', which is a recommended way of changing the attribute type programmatically4.

To change the type of ''my.attribute'' from text to int, the Architect should take two steps: A) Migrate data from table ''catalog_product_entity_text'' to ''catalog_product_entity_int'' for the attribute_id. This step will move the existing values of the attribute from the text table to the int table, which corresponds to the new type. D) Create a Data Patch and update 'my.attribute' type from ''text'' to ''int''. This step will update the attribute metadata in the database and reflect the new type. Option B is incorrect because the Admin panel does not allow changing the type of an existing attribute. Option C is incorrect because writing a plugin for \Magento\Eav\Model\Entity\Attribute\Backend\AbstractBackend::afterLoad() will not change the type of the attribute, but only load data from a different table. Option E is incorrect because running the command bin/magento indexer:reset catalog_product_attribute will not change the type of the attribute, but only reset the indexer status.

Question 4

An Adobe Commerce Architect designs a data flow that contains a new product type with its own custom pricing logic to meet a merchant requirement.

Which three developments are valid when reviewing the implementation? (Choose three.)



Answer : A, C, F

To create a new product type with its own custom pricing logic, you need to consider the following developments:

Content of the etc/product_types.xml file. This file will define the name, label, modelInstance, and priceModel of the new product type. The modelInstance will specify the custom type model that extends from the abstract Product Type model. The priceModel will specify the new price model that extends \Magento\Catalog\Model\Product\Type\Price.

Custom type model extended from the abstract Product Type model. This model will implement the logic and behavior of the new product type, such as how to prepare product for cart, how to process buy request, how to check product options, etc.

New price model extended \Magento\Catalog\Model\Product\Type\Price. This model will implement the custom pricing logic for the new product type, such as how to calculate final price, tier price, minimal price, etc.

Question 5

An Architect is reviewing a custom module that is logging customer activity data on storefront using observers. The client reports that logs were recorded while the client was previewing storefront catalog pages from Admin Panel for a future scheduled campaign, using Adobe Commerce staging preview functionality.

What should the Architect check first to address this issue9



Answer : C

It will allow you to exclude logging observers from being executed during staging preview functionality by adding them to bannedObservers parameter of \Magento\staging\Model\Event\Manager type in di.xml file. This will prevent customer activity data from being logged while previewing storefront catalog pages from Admin Panel for a future scheduled campaign.

The Architect should check the list of logging observers in bannedObservers parameter of \Magento\Staging\Model\Event\Manager type in di.xml. This parameter defines the list of observers that should not be executed during staging preview. The Architect should add the logging observers to this list to prevent them from recording customer activity data while previewing the storefront catalog pages from Admin Panel.

Question 6

A third-party company needs to create an application that will integrate the Adobe Commerce system to get orders data for reporting. The integration needs access to the get /vi/orders endpoint. It will call this endpoint automatically every hour around the clock. The merchant wants the ability to restrict or extend access to resources as well as to revoke the access using Admin Panel.

Which type of authentication available in Adobe Commerce should be used and implemented in a third-party system for this integration?



Answer : B

To create an application that will integrate the Adobe Commerce system to get orders data for reporting using the get /v1/orders endpoint, you should use OAuth-based authentication to provide access to system resources. OAuth is a token-passing mechanism that allows a system to control which third-party applications have access to internal data without revealing or storing any user IDs or passwords. The integration will be registered by the merchant in the admin panel and will perform an OAuth handshake during activation. The third-party system should follow OAuth protocol to authorize.The merchant will have the ability to restrict or extend access to resources as well as to revoke the access using Admin Panel.

Question 7

An Adobe Commerce Architect needs to log the result of a ServiceClass : : ge-Dara method execution after all plugins have executed. The method is public, and there are a few plugins declared for this method. Among those plugins are after and around types, and all have sortOrder specified.

Which solution should be used to meet this requirement?



Answer : C, C

thesortOrderproperty from the plugin node declared in di.xml determines the plugin's prioritization when more than one plugin is observing the same method. The Magento\Framework\Interception\PluginListInterface which is implemented by Magento\Framework\Interception\PluginList\PluginList is responsible to define when to call the before, after, and around methods for each plugin.

Therefore, to log the result of a ServiceClass::getData method execution after all plugins have executed, the solution should be:
