NEW QUESTION # 64
A merchant has noticed an error in the checkout. The accessed URL is /checkout.
Where can the developer find the responsible controller in the Magento.Checkout module?
- A. Controller/lndex/lndex.php
- B. Controller/Checkout/lndex.php
- C. Controller/lndex/Checkout.php
Answer: B
Explanation:
The controller responsible for handling the /checkout URL is located in Controller/Checkout/Index.php in the Magento.Checkout module1. This controller extends from \Magento\Checkout\Controller\Index\Index, which implements the execute() method that renders the checkout page1.
In the Magento_Checkout module, the responsible controller for the /checkout URL can be found in Controller/Checkout/Index.php. This controller handles the index action for the checkout process, initiating the checkout page when a customer navigates to /checkout. The organization of controllers in Magento follows a convention where the URL path corresponds to the directory structure within the module, making it easier to locate and understand the functionality associated with specific routes.
NEW QUESTION # 65
An Adobe Commerce developer wants to create a product EAV attribute programmatically which should appear as WYSIWYG in the admin panel. They have made sure that wysiwyg_enabled has been set to true, however, the attribute is not appearing as WYSIWYG in the admin panel.
What would be a possible reason?
- A. The input type is not set to text.
- B. The is_html_allowed_on_front Option iS Set tO false.
- C. The input type is not set to textarea.
Answer: C
Explanation:
Theinput_typeattribute of a product EAV attribute specifies the type of input field that will be used to enter the value of the attribute in the admin panel. Thetextareainput type is used for WYSIWYG fields. If theinput_typeattribute is not set totextarea, then the attribute will not appear as WYSIWYG in the admin panel.
To fix this, the developer should set theinput_typeattribute totextarea.
NEW QUESTION # 66
Which action, if any, should be taken to forbid Adobe Commerce Admin from performing specific actions?
- A. Enable custom roles in the store configuration, and assign admin user ID(s).
- B. This action cannot be taken since all admin users must have full access.
- C. Create a new user role with custom-defined resources, and assign it to the admin user
Answer: C
Explanation:
To forbid Adobe Commerce Admin from performing specific actions, a developer should create a new user role with custom-defined resources, and assign it to the admin user. This can be done by going toSystem > Permissions > Rolesand creating a new role. In theResourcessection, the developer can select the specific resources that they want to restrict the admin user from accessing.
To restrict specific actions within the Adobe Commerce Admin, the recommended approach is to utilize Magento's Access Control List (ACL). This can be done by creating a new user role with custom-defined resources and assigning this role to the admin user. This approach allows for granular control over what actions an admin user can perform by specifying allowed resources within the role. Magento's ACL system is designed to manage permissions effectively, ensuring that users only have access to the necessary functionalities required for their role.
NEW QUESTION # 67
A developer defined a new table in db.schema.xml while creating a new module.
What should be done to allow the removal of columns from the database when deleting them from db.schema.
xml?
- A. The removable columns should be defined in db_schema_whitelist.json.
- B. The removable columns should be defined in db.schema_blacklist.json.
- C. The columns should have "removable" attribute set to "true" in the db.schema.xml.
Answer: A
Explanation:
If a developer wants to allow the removal of columns from the database when deleting them fromdb.schema.
xml, they need to define the removable columns in thedb_schema_whitelist.jsonfile. This file will tell Magento which columns can be removed from the database.
To allow columns to be removed from the database when they are deleted fromdb_schema.xml, they must be listed in thedb_schema_whitelist.jsonfile. This file acts as a reference for which database schema elements are safe to modify or delete, providing a safeguard against unintentional data loss during schema updates.
NEW QUESTION # 68
An Adobe Commerce developer creates a new website using a data patch. Each website will have unique pricing by website. The developer does not have visibility into the production and staging environments so they do not know what the configuration currently is.
How would they ensure the configuration is deployed and consistent across all environments?
- A.
- B.
- C.
Answer: C
Explanation:
The correct answer isOption A. This approach ensures that the configuration is set using the CLI with the -- lock-config flag, which prevents the setting from being overridden by configuration changes in other environments.
* Understanding the Configuration Requirement:
* The developer needs to ensure consistent configuration across all environments without visibility into them. This calls for a method that can enforce configuration at a system level.
* Setting catalog/price/scope to 1 configures pricing to be scoped at the website level, as required.
* Using the CLI with --lock-config:
* The command bin/magento config:set catalog/price/scope 1 --lock-config not only sets the configuration but also locks it. This lock ensures that the setting will not be inadvertently changed by system configuration settings in other environments.
* By locking the configuration, the value becomes consistent across all environments and is stored in app/etc/config.php, which can be committed to version control and deployed across environments.
* Why Other Options Are Incorrect:
* Option B: While this option sets the configuration, it lacks the --lock-config flag. Without locking, the setting can still be overridden or altered in other environments, which does not guarantee consistency.
* Option C: Modifying the config.xml for setting catalog/price/scope could be an approach, but this method is not environment-proof. It also doesn't provide the same guarantee as using --lock- config, which explicitly prevents environment-specific changes from altering the configuration.
NEW QUESTION # 69
A developer wants to deploy a new release to the Adobe Commerce Cloud Staging environment, but first they need the latest code from Production.
What would the developer do to update the Staging environment?
- A. 1. Log in to the Project Web Interface.
2. Choose the Staging environment, and click Merge - B. 1, Log in to the Project Web Interface.
2. Choose the Staging environment, and click Sync - C. 1. Checkout to Production environment
2. Use the magento-cloud synchronize <environment-ID> Commerce CLI Command
Answer: B
Explanation:
To update the Staging environment with the latest code from the Production environment on an Adobe Commerce Cloud project, the developer would log in to the Project Web Interface, choose the Staging environment, and then click Sync. This action synchronizes the environments, bringing the latest changes from Production into Staging.
NEW QUESTION # 70
An Adobe Commerce Cloud developer wants to be sure that, even after transferring database from Production to Staging, the payment configurations are still valid on the Staging environment.
What does the developer need to add to be sure that the configurations are always properly set?
- A. Environment level environment variables.
- B. Project level environment variables.
- C. Lines in the dedicated core_conf ig_data_stg table.
Answer: A
Explanation:
The developer needs to add environment level environment variables to be sure that the payment configurations are always properly set on the Staging environment. Environment variables are configuration settings that affect the behavior of the Adobe Commerce Cloud application and services. Environment variables can be set at the project level or the environment level. Project level variables apply to all environments, while environment level variables override the project level variables for a specific environment. The developer can use environment level variables to customize the payment configurations for the Staging environment without affecting other environments. Verified References: [Magento 2.4 DevDocs]
NEW QUESTION # 71
How should a grid or form be included in an admin page layout using the Ul Component?
- A. <referenceContainername='content"> q <uiComponentname="example_listing.xml7> <
/referenceContainer> - B. <referenceContainername='content">
<uiComponentname="Vendor_Module::ul_component/example_listing.xml7> </referenceContainer> - C. <referenceContainername='contenf> q <uiComponent name="example_listing7> </referenceContainer>
Answer: C
Explanation:
To include a grid or form in an admin page layout using the UI Component, the correct approach is to use the< uiComponent name="example_listing"/>within a<referenceContainer name='content'>block of the layout XML file. This method directly references the UI component's configuration file (e.g.,example_listing.
xml) which defines the structure andfunctionality of the UI component, such as grids or forms. This configuration file is located under theview/adminhtml/ui_componentdirectory of the corresponding module.
NEW QUESTION # 72
An Adobe Commerce developer is tasked with adding an new export option for the order grid, they have added the following code for the export button within sales_order_grid.xml:
Upon testing, they are getting redirected, what would be a cause for this error?
- A. The developer has to add a formkey for the new export option.
- B. The layout cache needs to be refreshed.
- C. The option's uri attribute is not valid.
Answer: A
Explanation:
The developer has to add a formkey for the new export option because the formkey is required for security reasons. Without the formkey, the request will be rejected and redirected to the dashboard page. Verified References: [Magento 2.4 User Guide] [Magento 2.4 DevDocs] When adding custom export options to grids in Magento, it's crucial to include a form key for actions that involve form submission. Magento relies on form keys for CSRF (Cross-Site Request Forgery) protection, so omitting the form key can lead to redirects or failed operations.
* Form Key Requirement:
* In Magento, the form key is a hidden token included in forms to ensure that the request is valid.
This is particularly important for actions that change the state or export data, as it helps prevent unauthorized actions.
* Adding a custom export button triggers a form submission, which requires a valid form key.
Without it, Magento may redirect to a default page or the admin dashboard as a security measure.
* Why Option C is Correct:
* Option C correctly identifies the lack of a form key as the issue. When Magento detects a missing form key in sensitive operations, it defaults to a redirect to maintain security.
* Option A, concerning the URI, is less likely to cause a redirection. Similarly, Option B regarding layout cache would not directly impact CSRF validation, which is the cause of the redirection here.
* Solution:
* Modify the button or form submission logic to include a form key, typically by adding form_key=
{{formKey}} in the URL parameters or within the form data.
NEW QUESTION # 73
A developer found a bug inside a private method of a third party module class. How can the developer override the method?
- A. Create a custom class with the corrected logic, and define the class as a preference for original one in the di xml.
- B. Create a custom class with corrected logic, and define the class as preference in the preferences.xml.
- C. Create a plugin, implement correct logic in the after" method, and then define the plugin in the di.xml.
Answer: A
Explanation:
To override a private method in a third-party module class, the most effective approach is to use a preference.
This involves creating a custom class with the corrected logic and then defining this class as a preference for the original one in thedi.xmlfile. Plugins cannot be used to override private methods, final methods, final classes, or classes created without dependency injection. Therefore, the preference mechanism, which allows for the substitution of the entire class, becomes the viable method to override a private method and modify its behavior.
NEW QUESTION # 74
In a new release of a module, a developer decides to rename a table that was defined in the earlier versions.
Which action, if any, allows the developer to prevent data loss?
- A. Define onCreate="migrateDataFromAnotherTable(old_table_name)" attribute in the table tag.
- B. Declarative schema supports RENAME TABLE', so the data will be migrated to the new table automatically.
- C. Define the table and columns mapping in the db.schema_whitelist.json
Answer: C
Explanation:
When renaming a table in Magento, to prevent data loss, the developer must define the table and its columns mapping in thedb_schema_whitelist.jsonfile. This declarative schema approach ensures that the data migration tool knows about the changes and can migrate data from the old table to the newly named table without losing any data.
NEW QUESTION # 75
An Adobe Commerce developer has been tasked with applying a pricing adjustment to products on the website. The adjustments come from a database table. In this case, catalog price rules do not work. They created a plugin for getPrice on the price model, but the layered navigation is still displaying the old price.
How can this be resolved?
- A. Create a plugin for\Magento\Catalog\Model\Indexer\Product\Price::executeRow.
- B. Create an after plugin On \Magento\Catalog\Api\Data\BasePriceInterface:: getPrice.
- C. Create an implementation for \Magento\Catalog\Hodel\Product\PriceModifierlnterf ace.
Answer: A
Explanation:
The developer can resolve this issue by creating a plugin for
theMagento\Catalog\Model\Indexer\Product\Price::executeRow()method. This method is responsible for updating the product price index.
The plugin can be used to add the pricing adjustment from the database to the product price index. Once the product price index is updated, the layered navigation will display the correct price.
Here is an example of a plugin for theexecuteRow()method:
PHP
class MyPlugin
{
public function executeRow(
\Magento\Catalog\Model\Indexer\Product\Price $subject,
\Magento\Catalog\Model\Product $product,
array $data
) {
$adjustment = $this->getAdjustment($product);
$product->setPrice($product->getPrice() + $adjustment);
}
private function getAdjustment(Product $product)
{
$adjustment = $product->getData('adjustment');
if (!is_numeric($adjustment)) {
return 0;
}
return $adjustment;
}
}
This plugin will add theadjustmentdata from the product to the product price index. Once the product price index is updated, the layered navigation will display the correct price.
NEW QUESTION # 76
An Adobe Commerce developer wants to generate a list of products using ProductRepositorylnterf ace and search for products using a supplier_id filter for data that is stored in a standalone table (i.e., not in an EAV attribute).
Keeping maintainability in mind, how can the developer add the supplier ID to the search?
- A. Add a CUStOm filter to the Virtual type
"agento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\ProductFilterProce5sor for supplier_id field. In the custom filter, apply the needed join and filter to the passed $collection. - B. Write a before plugin On \Magento\Framework\Api\SearchCriteria\CollectionProcessorInterface: :
process(). Iterate through the $searchCriteria
provided for supplier_id, and if found, apply the needed join and filter to the passed scollection. - C. Write a before plugin on \Hagento\catalogVtodel\ProductRepository: :geti_ist() and register the search criteria passed. Write an event observer to 0 listen for the event cataiog_product_coiiection_ioad_before. Iterate through the registered search criteria, and if found, apply the needed join and filter to the events scollection.
Answer: A
Explanation:
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 References: [Magento 2.4 DevDocs] [Magento Stack Exchange] In Adobe Commerce, when you need to add a custom filter for a non-EAV attribute stored in a standalone table, the most maintainable approach is to create a custom filter for ProductFilterProcessor. This processor allows for customized search criteria handling, which can be extended to include custom joins and filters without altering core functionality or relying on plugins and observers.
* Why Custom Filter in ProductFilterProcessor is Preferred:
* The ProductFilterProcessor within SearchCriteria\CollectionProcessor is specifically designed to handle filtering of product collections. By extending this with a custom filter, the developer can implement joins and filters on standalone tables.
* This approach is modular and reusable, allowing any code that utilizes ProductRepositoryInterface to apply the supplier_id filter seamlessly.
* Implementation of Custom Filter:
* Define a custom filter class that implements the required logic to join the standalone table and apply the supplier_id filter.
* Register this custom filter with a virtual type in di.xml for ProductFilterProcessor, so it can process the supplier_id as part of the search criteria.
* Why Options A and C are Less Suitable:
* Option A relies on an event observer, which is less modular and may have performance implications since it requires listening to every product collection load event.
* Option C, while functional, involves modifying CollectionProcessorInterface::process(), which is more generic and not specifically tailored for product collection filtering.
NEW QUESTION # 77
An Adobe Commerce developer has been asked to modify the PageBuilder slider content type to allow a new custom content type (other than slide) to be assigned as a child. The developer has already created the new content type called improved_slide in their module. They now need to create a new view/adminhtml
/pagebuilder/content_type/slider. xml file in their module to allow the new content type to be a child of slider content types.
What is the correct xml to accomplish this?
- A.
- B.
- C.
Answer: A
Explanation:
The correct answer is Option C. This XML configuration is the correct way to define allowed child content types for a slider content type in Magento's PageBuilder.
Magento PageBuilder Content Type Structure:
In PageBuilder, each content type can specify which other content types are allowed as children.
This is done by defining the allowed_children array within the content type's XML configuration.
Analyzing Option C:
Arguments Definition: Option C uses the <arguments> node to define a new argument named allowed_children.
Array Structure: This argument is an array (xsi:type="array") that includes an item specifying the improved_slide as an allowed child with xsi:type="string".
This configuration is correct because it explicitly defines which child content types are allowed for the slider content type, adhering to Magento's structure for allowed child elements in PageBuilder.
Why Options A and B are Incorrect:
Option A: Uses a <children> node with policy="allow", which is not the standard way to define allowed children for PageBuilder content types. This format is incorrect and won't be recognized by PageBuilder.
Option B: Uses <allowed_descendants>, which also doesn't align with the way Magento's PageBuilder expects child content types to be declared. The correct term is allowed_children, not allowed_descendants.
NEW QUESTION # 78
How would a developer access RabbitMQ data on an Adobe Commerce Cloud Production environment?
- A. Using Project Web Interface
- B. Using local port forwarding
- C. Using RabbitMyAdmin
Answer: B
Explanation:
The way a developer would access RabbitMQ data on an Adobe Commerce Cloud Production environment is by using local port forwarding. This method allows the developer to connect to the RabbitMQ service instance through an SSH tunnel and access the RabbitMQ Management UI from a web browser. The developer needs to use the magento-cloud ssh command to establish the SSH connection and the
$MAGENTO_CLOUD_RELATIONSHIPS variable to retrieve the RabbitMQ connection details and login credentials.
NEW QUESTION # 79
An Adobe Commerce developer is asked to implement a 15% surcharge for all users from a 'Wholesale' customer group. Keeping best practices in mind, what is a correct to accomplish this?
- A. Create a Cart Price Rule that applies only to the 'Wholesale' group. Specify no conditions for the rule, and in the Actions section, specify for the rule to apply a "Percent of product price discount", with the
'Discount Amount" field set to -15. - B. Create an Observer to the cataiog_product_get_final_price event. Check if the current customer is in the
'Wholesale' group, and if so, retrieve the
product from the $observer->getEventC) data and Call $product->setData('final_price', $product-
>getData( 'final_price') * 1.15). - C. Declare a new total collector class to calculate the modified total if the current user is in the group, register it in the module's etc/sales .xml file, modify the checkout_cart_index.xml and checkout_index_index.xml layouts to include a new child in the totals block.
Answer: C
Explanation:
The best practice to add a surcharge in Magento is to create a custom total collector that calculates and applies the surcharge. This approach integrates smoothly with Magento's sales and checkout processes.
* Total Collector for Surcharge:
* Creating a new total collector class allows Magento to calculate a custom surcharge and display it in the appropriate sections of the checkout and order summaries.
* Registering this in etc/sales.xml ensures that Magento includes this total during order processing and ensures it's displayed properly on the frontend and backend.
* Why Option A is Correct:
* This approach follows Magento's framework for managing additional charges. It ensures the surcharge is correctly applied and displayed.
* Options B and C involve less maintainable and less integrated approaches. Option B misuses a Cart Price Rule, and Option C uses an observer, which does not fit well with Magento's total calculation architecture.
NEW QUESTION # 80
What folder would a developer place a custom patch on an Adobe Commerce Cloud project to have it automatically applied during the build phase?
- A. Add the patch file to the m2-patches/ directory
- B. Add the patch file to the m2-hotfixes/ directory
- C. Add the patch file to the patches/ directory
Answer: B
Explanation:
On an Adobe Commerce Cloud project, a custom patch should be placed in them2-hotfixes/directory to have it automatically applied during the build phase. The patches in this directory are applied in alphabetical order and can be used to apply quick fixes to the code that will be included in the build artifact.
NEW QUESTION # 81
Under which section should the soft dependency for a module be listed in app/code/<Vendor>/<Module>
/composer.json file?
- A. suggest*: {
- B. }
- C. }
optional": { - D. }
soft": {
Answer: A
Explanation:
Soft dependencies for a module should be listed under the "suggest" section in thecomposer.jsonfile of the module. This section is used to list packages that enhance or work well with the module but are not strictly required for the module to function. By using the "suggest" section, developers can inform others about optional packages that could improve functionality or integration with the module, without making them mandatory dependencies.
NEW QUESTION # 82

Answer: B,C
Explanation:
Adobe Commerce Cloud offers several out-of-the-box features, including built-in Fastly integration for CDN and web application firewall services, as well as continuous deployment capabilities through its cloud infrastructure.
* Continuous Deployment:
* Adobe Commerce Cloud supports continuous deployment workflows, allowing code to be automatically built, tested, and deployed through its integration with Git and cloud CI/CD pipelines.
* Fastly Integration:
* Fastly is included as a CDN and caching layer with Adobe Commerce Cloud, offering improved site speed and security through caching and a web application firewall.
* Why Options B and D are Correct:
* Both of these features are inherent to Adobe Commerce Cloud. Option A (Support ACL) is a part of the Magento Admin Panel but is not a cloud-specific feature, and Option C (Blog platform connector) is not provided out-of-the-box.
