An Adobe Commerce developer is developing a custom module. As part of their implementation they have decided that all instances of their Custom\Module\Model\Example class should receive a new instance of Magento\Filesystem\Adapter\Local. How would the developer achieve this using di. xml?
Correct Answer: A
Question 2
An Adobe Commerce developer is writing an integration test. They checked some Integration Tests for Magento core modules for reference and noticed that they use data fixtures initialized by adding annotations to test classes. For example: The developer wants to add their own fixture to test a MyVendor_MyModule they created. Which steps will make this possible?
Correct Answer: A
* Magento Integration Test Fixtures: * Integration tests in Magento often require test data to be set up using fixtures. * Fixtures are typically PHP scripts placed within a _files directory, which Magento looks for based on the module structure and path specified in the annotation. * Directory Structure for Module-Specific Fixtures: * The correct approach is to create the fixture within the module's own directory. The path follows: [module dir]/Test/Integration/_files/. * By placing it within the module directory, the fixture remains encapsulated and portable with the module itself. * Annotation Usage in Option A: * The @magentoDataFixture annotation specifies the path relative to the module directory. * In this case, using MyVendor_MyModule::Test/Integration/_files/my_fixture.php tells Magento to look within the module's integration test folder, ensuring modularity and easier maintenance. * Why Other Options Are Incorrect: * Option B: Storing fixtures in [magento root dir]/dev/tests/integration/testsuite/ is an older approach and does not follow module encapsulation best practices. It is better suited for Magento core modules rather than custom modules. * Option C: This option uses a similar path structure to Option A, but the provided annotation format lacks proper naming convention. It misses the proper path specification that is necessary for Magento to resolve the fixture correctly.
Question 3
An Adobe Commerce developer added a new API method to search and retrieve a list of Posts for a custom Blog functionality. This is the content of the module's etc/webapi.xml file: The new code has been deployed to production and the merchant is using https: //merchant. domain. com /swagger to review the new endpoint, but it is not visible in swagger. What would be a reason for this?
Correct Answer: B
In Adobe Commerce, when defining new API endpoints through the webapi.xml configuration file, the visibility of these endpoints in tools likeSwagger(now OpenAPI) depends on several factors, including authentication settings. According to the provided webapi.xml file: <?xml version="1.0"?> <routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd"> <route url="/V1/myvendor-blog/post/search" method="GET"> <service class="MyVendor\Blog\Api\PostRepositoryInterface" method="getList"/> <resources> <resource ref="MyVendor_Blog::Post_View"/> </resources> </route> </routes> * Option Asuggests moving the file to etc/webapi_rest/webapi.xml. However, this is incorrect because Adobe Commerce does not require separate XML files for REST and SOAP APIs in this context. The webapi.xml is used for defining routes for both. The structure and location provided in the question are correct for defining REST API routes. * Option Bis the correct answer. The resource reference MyVendor_Blog::Post_View indicates that this API endpoint is not anonymous; it requires authentication. In Adobe Commerce, if an API endpoint requires authentication, it won't be visible in Swagger (or the OpenAPI UI) unless you provide valid authentication credentials or tokens. This is part of Magento's security model where protected resources require tokens or OAuth to access. For the merchant to see this endpoint in Swagger, they must provide an integration token or OAuth token which has permissions for MyVendor_Blog::Post_View. This is detailed in the Adobe Commerce Developer Documentation under[Web API Authentication](https://x. com/i/grok?text=Web%20API%20Authentication). * Option Cmentions the @return annotation missing in the interface class. While proper annotations in PHPDoc are important for IDE autocompletion and documentation generation, they are not directly related to the visibility of an endpoint in Swagger. The visibility in Swagger is determined by the configuration in webapi.xml and the authentication settings, not by PHPDoc annotations. Thus, this option is incorrect in the context of the question. For further reading on how to manage and configure API endpoints in Adobe Commerce, including authentication, refer to the official Adobe Commerce Developer Guide: * Web API Configuration * Web API Authentication * Swagger Integrationfor testing and documenting APIs. This explanation covers the necessary aspects of Adobe Commerce API development, focusing on the configuration, authentication requirements, and how these affect the visibility of API endpoints in development tools like Swagger.
Question 4
An Adobe Commerce Cloud merchant has been experiencing significant downtime during production deployment. They have already checked that the application is in ideal state. In addition to the configuration of the SCD.MATRIX variable to reduce amount of unnecessary theme files, what would be the next steps to reduce the downtime?
Correct Answer: A
To minimize downtime during deployment, one of the most effective strategies is to configure static content deployment (SCD) to run during the build phase and optimize the number of threads used during the process. * Configuring SCD in the Build Phase: * Running SCD during the build phase reduces the amount of work required during the deployment phase, which helps in reducing downtime. * Increasing SCD.THREADS: * Increasing the number of threads (SCD.THREADS) speeds up the static content generation by utilizing more parallel processing, which can significantly reduce build time. * Why Option A is Correct: * Configuring SCD in the build phase and increasing SCD.THREADS are both recommended practices to minimize deployment time. * Option B's recommendation to decrease threads would slow down SCD, and Option C does not provide an active approach to adjust thread counts for optimizing the process.
Question 5
Which command should be used to refresh the cache using the command line?
Correct Answer: A
To refresh the cache using the command line in Magento, the commandbin/magento cache:clean <type>is used. This command clears the cache for the specified type, such as configuration, layout, or block HTML. Cleaning the cache is an essential maintenance task that helps to update the store's frontend with the latest changes and ensure that customers see the most current content. This command is particularly useful during development or after making changes to the store's configuration or layout.
