The reason why the new endpoint is not visible in swagger is that since the new endpoint is not

anonymous, the merchant needs to enter a valid integration token in swagger in order to see the

new method. The webapi.xml file specifies that the resource for the new endpoint is

MyVendor_Blog::post, which means that only authorized users with this permission can access it. To

generate an integration token, the merchant needs to create an integration in the admin panel and

activate it. Then they can copy the token and paste it in swagger’s authorization field. Verified

The correct answers are A and C.

The errors in the snippet are:

Column roll_no does not have an index. It is needed since attribute_identity is set to true.

Column student_name does not have an attribute length.

The attribute_identity attribute specifies whether the primary key of the table should be auto-

incremented. If attribute_identity is set to true, then the roll_no column must have an index. The

student_name column does not have an attribute length, which is required for string columns.

The following code shows how to fix the errors:

The command used to upgrade ECE-Tools on an Adobe Commerce Cloud platform is composer

update magento/ece-tools --with-all-dependencies. This command will update the ECE-Tools

package and its dependencies to the latest version available in the composer repository. The

developer then needs to commit and push the changes to the composer.json and composer.lock files

and redeploy the environment. Verified Reference: [Magento 2.4 DevDocs]

To configure the tracking_level parameter in di.xml to have a value of 4 for the Download class and

all classes that extend Download, the developer would use the following code:

The setting element is used to set a configuration value for a specific model. The rewrite element is

used to override the default configuration value for a specific model. In this case, the tracking_level

parameter is set to 4 for all models that extend Download.

The developer can add a custom filter to the virtual type

Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\ProductFilterProce5sor for

supplier_id field. In the custom filter, the developer can apply the needed join and filter to the

passed $collection. This is the recommended way to extend the search criteria for products using

dependency injection and plugins. Verified Reference: [Magento 2.4 DevDocs] [Magento Stack
