NEW QUESTION # 43
The value of a product attribute in the Adobe Commerce system needs to have a different format before it is displayed. Which attribute model class is responsible for this?
- A. Source
- B. Frontend
- C. Backend
Answer: B
Explanation:
The frontend attribute model class is responsible for formatting the value of a product attribute before it is displayed on the storefront. This class can implement methods such as getValue, getLabel, getInputType, and getOptionText to modify the attribute value.
The backend attribute model class is responsible for saving and loading the attribute value to and from the database. The source attribute model class is responsible for providing the list of options for an attribute.
Verified References: [Adobe Commerce Developer Guide - Attribute models] In Adobe Commerce (Magento 2), the formatting of product attribute values before they are displayed is handled by the attribute's frontend model. The frontend model, typically extending
\Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend, is responsible for preparing the attribute value for display in the frontend, including formatting dates, adding pricing structures, and more.
The backend model deals with saving and loading attribute data, while the source model provides options for select attributes.
NEW QUESTION # 44
There is the task to create a custom product attribute that controls the display of a message below the product title on the cart page, in order to identify products that might be delivered late.
The new EAV attribute is_delayed has been created as a boolean and is working correctly in the admin panel and product page.
What would be the next implementation to allow the is_delayed EAV attribute to be used in the .phtml cart page such as $block->getProduct()->getIsDelayed()?
A)
Create a new file etc/catalog_attributes.xmi:
B)
Create a new file etc/extension attributes.xmi:
C)
Create a new file etc/eav attributes.xmi:
- A. Option C
- B. Option A
- C. Option B
Answer: B
Explanation:
To allow theis_delayedEAV attribute to be used in the .phtml cart page, the developer needs to create a new file calledetc/catalog_attributes.xmi. This file will contain the definition of theis_delayedattribute.
The following code shows how to create theetc/catalog_attributes.xmifile:
XML
<?xml version="1.0"?>
<catalog_attributes>
<attribute code="is_delayed" type="int">
<label>Is Delayed</label>
<note>This attribute indicates whether the product is delayed.</note>
<sort_order>10</sort_order>
<required>false</required>
</attribute>
</catalog_attributes>
Once theetc/catalog_attributes.xmifile has been created, theis_delayedattribute will be available in the .phtml cart page. The attribute can be accessed using thegetIsDelayed()method of theProductclass.
PHP
$product = $block->getProduct();
$isDelayed = $product->getIsDelayed();
TheisDelayedvariable will contain the value of theis_delayedattribute. If the value of the attribute is 1, then the product is delayed. If the value of the attribute is 0, then the product is not delayed.
NEW QUESTION # 45
A developer would like to initialize a theme in Adobe Commerce. Which two files are required to complete this task? (Choose two.)
- A. composerjson
- B. themexml
- C. registration.php
- D. theme.less
Answer: A,C
Explanation:
To initialize a theme in Adobe Commerce, at least two files are required:registration.phpandtheme.xml. The registration.phpfile is used to register the theme within the system, andtheme.xmldefines the theme's name, parent (if any), and other metadata. Thetheme.lessfile is not required for theme initialization but may be used for custom styling. The correct option fortheme.xmlis represented as "theme.xml" (D), not "themexml" as mentioned in the options.
NEW QUESTION # 46
An Adobe Commerce developer is creating a module (Vendor.ModuleName) to be sold on the Marketplace.
The new module creates a database table using declarative schema and now the developer needs to make sure the table is removed when the module is disabled.
What must the developer do to accomplish this?
- A. There is nothing further the developer needs to do. The table will be removed when the when bin
/magento module:uninstall vendor_ModuleName is run. - B. Add a schema patch that implements Magento\Framework\setup\Patch\PatchRevertabieinterface and drops the table in the revert function.
- C. There is nothing further the developer needs to do. The table will be removed when the module is disabled and bin/magento setup:upgrade is run.
Answer: C
Explanation:
When you disable a module, Magento removes all of its declarative schema changes from the database the next time you run bin/magento setup:upgrade." This means that when the developer disables the module and runs setup:upgrade, Adobe Commerce will automatically handle the removal of the database table created by the module's declarative schema.
For reference, here are some key points from the documentation:
* [Disable a Module](https://x.com/i/grok?text=Disable%20a%20Module)- This section explains how Magento handles the database schema when a module is disabled.
* Declarative Schema Configuration- Provides an overview of how declarative schema works, including its behavior when modules are disabled or uninstalled.
Therefore, based on the official Adobe Commerce documentation, the correct action for the developer is to do nothing further beyond disabling the module and running bin/magento setup:upgrade. Magentowill take care of removing the table associated with the module as part of its schema management process.
NEW QUESTION # 47
Under which section should the soft dependency for a module be listed in app/code/<Vendor>/<Module>
/composer.json file?
- A. }
soft": { - B. }
- C. }
optional": { - D. suggest*: {
Answer: D
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 # 48
In which two directories are third-party modules located by default? (Choose two.)
- A. app/packages/
- B. app/modules/
- C. app/code/
- D. vendor/
Answer: C,D
Explanation:
By default, third-party modules are located in vendor/ or app/code/ directories. The vendor/ directory contains modules that are installed using Composer, while the app/code/ directory contains modules that are manually copied or cloned from a repository.
Third-party modules in Magento 2 are typically located in two directories by default: thevendor/directory and theapp/code/directory. Thevendor/directory is used for modules that are installed via Composer, Magento's dependency manager, which includes both Magento's core modules and third-party modules. Theapp/code/ directory is used for custom modules developed specifically for the project or for third-party modules that are manually installed without Composer. These conventions provide a structured approach to managing Magento modules, whether they are part of Magento's core functionality, contributed by the community, or developed for specific projects.
NEW QUESTION # 49

- A. 1. All required Magento patches included in the Cloud Patches for Commerce package.
2. Selected optional Magento patches included in the Quality Patches Tool.
3. Custom patches in the /m2-hotfixes directory in alphabetical order by patch name. - B. 1. All required Magento patches included in the Cloud Patches for Commerce package.
2. Custom patches in the /m2-hotfixes directory in alphabetical order by patch name.
3. Selected optional Magento patches included in the Quality Patches Tool. - C. 1. Custom patches in the /m2-hotfixes directory in alphabetical order by patch name.
2. All required Magento patches included in the Cloud Patches for Commerce package.
3. Selected optional Magento patches included in the Quality Patches Tool.
Answer: A
Explanation:
The order in which the ECE-Tools package applies patches is as follows:
* All required Magento patches included in the Cloud Patches for Commerce package.
* Selected optional Magento patches included in the Quality Patches Tool.
* Custom patches in the /m2-hotfixes directory in alphabetical order by patch name.
The ECE-Tools package is a set of scripts and tools designed to manage and deploy Adobe Commerce Cloud projects. The Cloud Patches for Commerce package is a dependency of ECE-Tools that provides a set of required patches for Magento core issues that affect Adobe Commerce Cloud functionality. The Quality Patches Tool is an optional tool that allows developers to apply individual patches for specific Magento issues without waiting for a full product release. The /m2-hotfixes directory is a directory where developers can place their own custom patches for their Adobe Commerce Cloud projects. Verified References: [Magento 2.4 DevDocs]
NEW QUESTION # 50
A merchant of an Adobe Commerce Cloud project wants to setup one of their websites using a subdomain.
The merchant is considering the domain to be set as secondstore.example.com.
In addition to editing the magento-vars.php file, and apply a domain check and set $_SERVER
["MAGE_RUN_CODE"] and $_SERVER["MAGE_RUN_TYPE"].
What file is required to perform this action?
- A. Configure secondstore.example.com subdomain route in .magento/services.yaml.
- B. Configure secondstore.example.com subdomain route in .magento/routes.yaml.
- C. Configure secondstore.example.com subdomain route in NGINX virtual-host configuration file.
Answer: B
Explanation:
In Adobe Commerce Cloud, routing configurations for custom domains and subdomains are managed within the .magento/routes.yaml file. This file defines how requests are directed to the application and is essential for setting up different stores or websites with unique subdomains.
* Using .magento/routes.yaml for Subdomain Configuration:
* To set up a new subdomain, like secondstore.example.com, you need to configure the route in .
magento/routes.yaml. This file handles all routing and domain configurations for Adobe Commerce Cloud projects.
* Why Option C is Correct:
* .magento/routes.yaml is designed specifically for defining routing rules, including subdomains, making it the appropriate choice for this task.
* Option A (NGINX configuration) and Option B (.magento/services.yaml) are not correct because they don't directly manage domain routing in Adobe Commerce Cloud.
* Example Configuration:
http://secondstore.example.com/:
type: upstream
upstream: "mymagento:80"
NEW QUESTION # 51
When researching some issues with the indexer, an Adobe Commerce developer is seeing errors in the logs similar to Memory size allocated for the temporary table is more than 20% of innodb_buffer_pool_size. It is suggested that the client update innodb_buf f er_pool_size or decrease the batch size value.
Why does decreasing the batch size value improve performance?
- A. This allows for more PHP threads to be utilized during the process.
- B. This decreases memory usage for the temporary table.
- C. This allows for a longer timeout per batch process.
Answer: B
Explanation:
Decreasing the batch size value improves performance by reducing the memory usage for the temporary table.
The batch size value determines how many rows of data are processed at a time by the indexer. A large batch size value can cause the allocated memory size for the temporary table to exceed 20% of innodb_buffer_pool_size, which can result in errors and slow down the indexing process. By lowering the batch size value, the indexer can process the data more efficiently and avoid memory issues. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange] The error message regarding innodb_buffer_pool_size indicates that the temporary table's memory usage is high. Decreasing the batch size value directly reduces the number of rows processed in each batch, which in turn reduces the memory requirements for the temporary table.
* Impact of Batch Size on Memory Usage:
* The batch size determines how many records are processed at one time. By lowering the batch size, fewer records are processed, which reduces the amount of temporary table memory needed, alleviating the pressure on the InnoDB buffer pool.
* When the memory required by temporary tables exceeds the InnoDB buffer pool limit, MySQL might swap to disk, leading to slower performance and increased I/O.
* Why Option A is Correct:
* Reducing the memory footprint of temporary tables helps to prevent situations where memory constraints slow down or disrupt indexer operations.
* Options B and C are incorrect as they do not directly impact memory usage. Batch size adjustments do not affect timeout settings or PHP thread usage.
* Recommendations:
* In addition to adjusting the batch size, consider optimizing the innodb_buffer_pool_size setting based on server capacity to better handle larger operations if needed.
NEW QUESTION # 52
An Adobe Commerce Cloud developer wants to check the staging environment deployments history (i.e.
branch, git, merge, sync). Where can the developer look up the history of the staging environment?
- A. New Relic
- B. Adobe Commerce admin panel
- C. Project Web Interface
Answer: C
Explanation:
The Project Web Interface is the main dashboard for managing Adobe Commerce Cloud projects. This includes the ability to check the staging environment deployments history.
The developer can look up the history of deployments to the staging environment, including branch, git merge, and sync operations, in the Project Web Interface. This interface provides adetailed log of all actions taken on the project, including deployments, enabling developers to track changes and troubleshoot issues that may arise.
NEW QUESTION # 53
An Adobe Commerce developer is trying to create a custom table using declarative schema, but is unable to do so.
What are two errors in the snippet above? (Choose two.)
- A. Column (roll_no) does not have index. It is needed since attribute identity is set to true.
- B. Column (student_name) does not have attribute length.
- C. null is not a valid value for column (roll_no).
- D. Column (entity_id) does not have index. It is needed since attribute identity is set to false.
Answer: A,B
Explanation:
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.
Theattribute_identityattribute specifies whether the primary key of the table should be auto-incremented.
Ifattribute_identityis set totrue, then theroll_nocolumn must have an index. Thestudent_namecolumn does not have an attribute length, which is required for string columns.
The following code shows how to fix the errors:
XML
<table name="vendor_module_table">
<entity_id>
<type>int</type>
<identity>true</identity>
<unsigned>true</unsigned>
<nullable>false</nullable>
</entity_id>
<roll_no>
<type>int</type>
<identity>false</identity>
<unsigned>true</unsigned>
<nullable>false</nullable>
<primary_key>true</primary_key>
<index>true</index>
</roll_no>
<student_name>
<type>string</type>
<length>255</length>
<nullable>false</nullable>
</student_name>
</table>
Once the errors have been fixed, the table can be created successfully.
NEW QUESTION # 54
A Project Architect needs to add a new developer who needs to be able to push code in an Adobe Commerce Cloud project. No integration with a third-party repository provider is setup.
What two actions would be required to ensure the developer has access? (Choose Two.)
- A. The developer's SSH public key must be added into a file named ~/.ssh/authorized_keys
- B. The developer needs to add SSH public key in the Cloud Account dashboard settings
- C. The Adobe Commerce admin user must be created and the developer's SSH public key must be added on their local system
- D. The developer's email must be added under Users in the Cloud Project Web Ul
Answer: B,D
Explanation:
To ensure the developer has access to push code in an Adobe Commerce Cloud project, the developer's email must be added under Users in the Cloud Project Web UI and the developer needs to add SSH public key in the Cloud Account dashboard settings. The Cloud Project Web UI is a web interface that allows managing and configuring Adobe Commerce Cloud projects and environments. The developer's email must be added under Users to grant them access to the project and assign them a role and permissions. The Cloud Account dashboard settings is a web interface that allows managing and configuring Adobe Commerce Cloud accounts and SSH keys. The developer needs to add SSH public key in the settings to enable secure connection to the project and environments via SSH. Verified References: [Magento 2.4 DevDocs]
NEW QUESTION # 55
What does a URL Rewrite do?
- A. It updates the URL to a domain that is not being Indexed.
- B. It changes the way a URL appears in the browser
- C. It updates the URL that is stored on the server.
Answer: B
Explanation:
A URL Rewrite in Magento changes the way a URL appears in the browser. This is particularly useful for improving the readability and SEO of a URL. For example, a URL rewrite can be used to transform a long and complex URL into a shorter and more user-friendly version. It's important to note that while a URL rewrite changes the URL's appearance in the browser, it doesn't change the actual location of the resource on the server. This distinction is crucial for understanding how Magento handles URL rewrites and redirects, facilitating a more intuitive navigation structure within the store without altering the underlying server resources.
NEW QUESTION # 56
Which price type should be used if the developer wants to provide a discount for a product based on quantity, for example, being able to buy two for X amount each?
- A. Special Price
- B. Tier Price
- C. Group Price
Answer: B
Explanation:
Tier prices are used to provide discounts for products based on quantity. For example, you could set a tier price that allows customers to buy two products for X amount each.
The tier price is used when a developer wants to offer a discount based on the quantity purchased. For example, buying two or more units of a product at a reduced price per unit. Tier pricing allows setting different prices for different quantities, encouraging customers to buy more. Special price is a flat discounted price regardless of quantity, and group price is used to set special prices for specific customer groups, not for quantity-based discounts.
NEW QUESTION # 57
A merchant wants to include taxes In an Adobe Commerce store. Which option can have a tax class assigned to it?
- A. Category
- B. Shipping
- C. Order
Answer: B
Explanation:
According to the Adobe Commerce User Guide, a tax class can be assigned to either a product or a customer group in Adobe Commerce. A product tax class determines how a product is taxed, while a customer tax class determines how a customer is taxed based on their location and group membership. Shipping is considered as a product tax class in Adobe Commerce, and it can be assigned to different shipping methods or rates. The other options are not valid for assigning a tax class.
In Adobe Commerce, tax classes can be assigned to products and shipping. Categories, however, do not have tax classes assigned to them directly. Tax classes applied to shipping allow merchants to specify how taxes should be calculated for shipping costs, making option B the correct answer. Orders and categories do not have direct associations with tax classes in the same way products and shipping do.
NEW QUESTION # 58
A message queue currently has queue/consumer-wait-for-messages set to true, which allows the consumer process to run until a message is inserted into the queue. A piece of functionality is driven by data stored in the model
\Magento\variable\Model\variable and this value is only loaded once during the consumer run. If the variable is updated we want the consumer to restart so that the new value is loaded into memory without having to reload the variable on each message consumed.
The Adobe Commerce developer has created an after plugin on the \Magento\Variable\Model\variable:: save() function.
How would the developer use the plugin to trigger the consumer restart?
- A. Set the global Cache key trigger_consumer_restart t0 1.
- B. Call the function \Magento\Framework\MessageQueue\PoisonPill\Poi5onPillPutInterface::put().
- C. Call the function \Magento\Framework\MessageQueue\Consumers\TriggerRe5tartInterface:trigger().
Answer: B
Explanation:
In Adobe Commerce, when a consumer process needs to restart, the PoisonPillPutInterface can be used. The put() method of this interface triggers a "poison pill," which signals running consumers to restart. This is particularly useful when updated data needs to be reloaded into memory, as in this scenario with the
\Magento\Variable\Model\Variable.
Poison Pill Mechanism:
The poison pill method tells the message queue consumer to stop its current process and restart, allowing it to pick up any configuration or data changes that occurred since the last start.
Why Option A is Correct:
By calling PoisonPillPutInterface::put(), the consumer will receive a restart signal, which is ideal for cases where data loaded at the beginning of the consumer's lifecycle must be updated.
Option B is incorrect because TriggerRestartInterface::trigger() does not exist in the Magento framework.
Option C is also incorrect as setting a cache key alone does not trigger a consumer restart.
Implementation:
Use an after plugin on the save() method to trigger PoisonPillPutInterface::put() after the variable is saved.

Answer: A
Explanation:
The database engine that is part of the infrastructure of Adobe Commerce Cloud projects is MariaDB.
MariaDB is a fork of MySQL that offers improved performance, scalability, and security features.
The database engine that is part of the infrastructure of Adobe Commerce Cloud projects is MariaDB. Adobe Commerce Cloud is configured to use MariaDB, which is a binary drop-in replacement for MySQL and is chosen for its performance, reliability, and feature set.
NEW QUESTION # 60
An Adobe Commerce developer has installed a module from a third-party vendor. This module fires a custom event named third_party_event_after and also defines an observer named third_party_event_after_observer that listens to that event. The developer wants to listen to this custom event in their own module but wants to execute their observer's logic after the third_party_event_after_observer observer has finished executing.
What would the developer do to ensure their observer runs after the observer defined by the third-party module?
- A. This is not possible as observers listening to the same event may be invoked in any order.
- B. Ensure the third-party module is listed in the <sequence> node of the developer's module.xmi file.
- C. Set the sort order of the new observer to be less than that of the third-party vendor's observer.
Answer: A
Explanation:

NEW QUESTION # 61
An Adobe Commerce developer successfully added a new column to the customers grid. This column needs the data to be formatted before showing its content in the grid.
According to best practices, how would the developer add the custom logic to render the column?
- A. 1. Override the Magento\Customer\Ui\Component\DataProvider Class using a preference.
2. Override the getData() method and add the custom logic per row. - B. 1. Create an after pluginforMagento\Ui\Component\Listing\Columns\Column::prepareColumn().
2. Add the custom logic within the afterPreparecoiumn method. - C. 1. Create a custom class extending flagento\Ui\Component\Listing\Columns\Colunm.
2. Add the custom logic within the prepareDataSource method.
3. Add an attribute class to the column node within the module's customer_listing.xml.
Answer: C
Explanation:
The best practice to add custom logic for data formatting in a grid column is to create a new class extending
\Magento\Ui\Component\Listing\Columns\Column. The prepareDataSource method is designed for processing and formatting data before it is displayed in the UI component.
* Using prepareDataSource in a Custom Column Class:
* By extending \Magento\Ui\Component\Listing\Columns\Column, you gain access to the prepareDataSource method, where you can manipulate data as needed.
* Adding a custom class allows for reusability and modular code, which is in line with Magento's architecture.
* Why Option B is Correct:
* This option uses Magento's UI component structure properly, focusing on the intended class and method for grid data manipulation. Option A involves an unnecessary plugin, and Option C with DataProvider preference is generally discouraged for simple UI modifications.
* Implementation Steps:
* Extend the Column class and add your logic in the prepareDataSource method.
* Then, in your customer_listing.xml, reference this class within the <column> node using the class attribute.
NEW QUESTION # 62
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.
