Adobe AD0-E722 Exam Dumps & Practice Test Questions

Question 1:

A business plans to develop an Adobe Commerce site to sell products domestically. The country’s tax regulations are very intricate and require a tailored tax calculation solution. 

As an Architect, how should you implement a custom tax calculation that applies to all orders in Adobe Commerce following best practices?

A. Attach a new observer to the “sales_quote_collect_totals_before” event and add the custom tax to the quote
B. Create a before plugin on \Magento\Quote\Model\QuoteManagement::placeOrder() to add the custom tax to the quote
C. Define a new total collector within a custom module by configuring it in the “etc/sales.xml” file

Correct answer: C

Explanation:

When customizing tax calculations in Adobe Commerce (Magento), it is essential to follow Magento’s architectural best practices to maintain system stability, extensibility, and proper integration within the order processing lifecycle. The optimal approach is to create a custom total collector declared in the etc/sales.xml configuration file of your module.

Magento uses the concept of total collectors to calculate different totals such as subtotal, shipping, discounts, and taxes during quote and order processing. By defining a custom total collector, you create a dedicated class responsible for computing your specific tax logic, and Magento integrates it cleanly with its core total calculation workflow. This approach ensures your custom tax is applied at the correct stage, in the right order relative to other totals, and is compatible with Magento’s internal mechanisms for totals aggregation and display.

Why are the other options less appropriate?

• A: Using an observer on the event sales_quote_collect_totals_before may appear viable since it fires during totals calculation. However, observers lack the explicit ordering and control that total collectors provide, potentially causing conflicts or inconsistent results, especially when combined with other custom totals like shipping or discounts. It also reduces maintainability and clarity.

• B: Implementing a before plugin on placeOrder() manipulates the quote just before order placement, which is too late in the process to accurately calculate totals. This can cause discrepancies and violates the separation of concerns principle, since totals calculation should happen prior to order placement, not during it.

Therefore, declaring a total collector in etc/sales.xml is the Magento-recommended and scalable method to handle complex tax logic, ensuring proper integration with the entire order and checkout process.

Question 2:

A third-party company needs to build an application that integrates with Adobe Commerce to fetch order information from the GET /V1/orders API endpoint every hour. The merchant requires control over access management via the Admin Panel, including the ability to restrict, extend, or revoke access. 

What is the best authentication method for this integration?

A. Use token-based authentication to get an Admin Token by providing the admin username and password, then use it as a Bearer Token
B. Use token-based authentication to obtain an Integration Token created and enabled via the Admin Panel, then use it as a Bearer Token
C. Use OAuth-based authentication where the integration is registered and activated in the Admin Panel, and the third-party system follows OAuth for access authorization

Correct answer: C

Explanation:

When integrating external applications with Adobe Commerce APIs, securing access and maintaining fine-grained control over permissions is critical. The best practice is to use OAuth-based authentication, which provides a secure, flexible, and manageable mechanism for authorizing third-party applications.

Let’s analyze the options:

• A: Using an Admin Token involves directly authenticating with an admin username and password. This grants full administrative privileges, which is risky as it exposes sensitive credentials and offers excessive permissions beyond what the integration typically requires. This approach also lacks flexibility in access control and is less secure, as revoking or modifying tokens is more cumbersome.

• B: Using an Integration Token created via the Admin Panel is an improvement over an Admin Token since it’s intended for integrations and can be limited to specific scopes. However, token management is less dynamic, and it lacks advanced features such as token expiration, refresh, and granular authorization flows. This reduces flexibility in managing access permissions over time.

• C: OAuth is designed for secure third-party integrations. When an integration is registered in the Admin Panel, it follows a standardized OAuth handshake process that generates tokens with limited scopes and expiration. Merchants can easily manage, restrict, or revoke access through the Admin interface, making it simple to maintain control. OAuth tokens support automatic renewal and reduce risks related to credential exposure, offering the most secure and manageable solution.

In summary, OAuth offers the best combination of security, flexibility, and administrative control for API integrations requiring periodic access to sensitive data like order information. It aligns with Adobe Commerce’s recommended practices for third-party integrations.

Question 3:

An Architect is developing a custom module that requires reading multiple XML configuration files declared across the system, merging their data, and making the combined values accessible within a PHP class. 

What are two essential steps the Architect should follow to accomplish this? (Select two.)

A. Inject a dependency for Magento\Framework\Config\Data as a “reader” in the module’s di.xml.
B. Create a plugin for the \Magento\Framework\Config\Data::get() method to read the custom XML files.
C. Build a Data class that implements the \Magento\Framework\Config\Data interface.
D. Add the custom XML filename to the Magento\Config\Model\Config\Structure\Reader configuration in di.xml.
E. Develop a Reader class that implements \Magento\Framework\Config\Reader\Filesystem.

Correct Answers: A, D

Explanation:

When an Architect needs to integrate custom XML configuration files into a Magento module and have the system read and merge them, the solution involves leveraging Magento’s built-in configuration framework.

Step A is critical because injecting the dependency for Magento\Framework\Config\Data in di.xml allows your module to utilize Magento’s native configuration reading and merging logic. This class acts as a central point for accessing configuration data loaded from various XML files, ensuring that your module can programmatically retrieve merged configuration values without re-implementing the reading logic.

Step D is equally important. By appending your custom XML file’s name to the list of files handled by Magento\Config\Model\Config\Structure\Reader in di.xml, you ensure Magento includes your new XML during its configuration merge process. This step effectively registers your XML file within Magento’s configuration system, allowing your module to participate in the global configuration merge.

Why the other options don’t fit:
Option B suggests writing a plugin on the get() method of Magento\Framework\Config\Data. This is unnecessary since plugins are intended to alter behavior, not to load or merge XML files. The configuration framework already handles reading and merging automatically.

Option C proposes creating a custom class implementing \Magento\Framework\Config\Data. Magento’s existing class suffices for most cases, so unless highly specialized behavior is needed, this is redundant.

Option E involves creating a new Reader class implementing Filesystem. While this could work for very complex scenarios, it is typically unnecessary. Simply appending your file to the existing reader is a simpler, cleaner approach that leverages Magento’s architecture efficiently.

In summary, the correct approach involves configuring Magento to recognize your XML file and using its default data reader to access merged configurations, which is achieved by injecting the reader dependency (A) and registering your XML file in the reader’s configuration (D).

Question 4:

An Adobe Commerce Architect adds a stopword file named stopwordsJtJT.csv for the Italian locale and places it in the directory:
<magento_root>/app/code/CustomVendor/Elasticsearch/etc/stopwords

What is the proper way to update the stopwords directory path within the custom module?

A. Configure the stopwordsDirectory and add CustomVendor_Elasticsearch to the stopwordsModule parameter of \Magento\Elasticsearch\SearchAdapter\Query\Preprocessor\Stopwords via di.xml.
B. Create a class implementing \Magento\Framework\Setup\Patch\PatchInterface to change the default value of elasticsearch/custom/stopwordspath in the core_config_data table.
C. Update the stopwordsDirectory parameter of \Magento\Elasticsearch\Model\Adapter\Document\DirectoryBuilder using a stopwords/it.xml file in the module, allowing Adobe Commerce to automatically detect the change.

Correct Answer: C

Explanation:

When customizing stopwords in Adobe Commerce (Magento) for a specific language or locale such as Italian, the most efficient and supported method is to configure the stopwords directory within the custom module’s configuration files.

Option C is the recommended approach because Adobe Commerce provides a flexible way to specify stopwords locations using XML configuration files. By creating or modifying a file like stopwords/it.xml inside your module, you set the stopwordsDirectory parameter for the \Magento\Elasticsearch\Model\Adapter\Document\DirectoryBuilder class. Magento’s system automatically detects this configuration and applies the new directory path without requiring manual core configuration changes or invasive custom code.

This approach aligns with Magento’s modular design and enables easy localization support and maintenance. The architecture handles loading stopword files based on locale, making this method both elegant and reliable.

Why other options are less appropriate:
Option A involves altering the dependency injection (di.xml) configuration for the Stopwords preprocessor class. While technically possible, this is unnecessarily complicated and could introduce maintenance challenges. Dependency injection is typically reserved for changing class behaviors or injecting services, not for specifying file paths in this context.

Option B suggests creating a database patch to change the stopwords path in the core_config_data table. This is overkill and not recommended for a directory path change within a module. Patches are useful for upgrading or changing persistent data but not ideal for modular configuration files. It also risks harder upgrades and more complicated version control.

In summary, using a locale-specific XML file (stopwords/it.xml) within the custom module to set the stopwordsDirectory parameter is the cleanest, most maintainable method to update stopwords in Adobe Commerce, making Option C the correct choice.

Question 5:

A client operates multiple warehouses, each with daily varying shipping costs depending on available workforce. The solution architect must ensure that customer orders are fulfilled from the warehouse that is both open and offers the lowest shipping cost. 

How should this requirement be best implemented in Magento?

A. Create a preference class for Magento\InventoryShipping\Plugin\Sales\Shipment\AssignSourceCodeToShipmentPlugin to assign the lowest-cost warehouse for shipments.
B. Develop a new class that implements Magento\InventorySourceSelectionApi\Model\SourceSelectionInterface to return open warehouses sorted by cost.
C. Create an after plugin on Magento\InventoryDistanceBasedSourceSelection\Model\Algorithms\DistanceBasedAlgorithm to sort warehouse sources by shipping cost.

Correct Answer: B

Explanation:

In this case, the client needs to ensure orders are shipped from the lowest-cost warehouse that is open on the day of shipment. To implement this, the best approach is to customize the warehouse selection logic in Magento’s inventory system.

Magento’s Inventory Management system manages multiple warehouses (inventory sources). The InventorySourceSelectionApi allows customization of the logic used to select the warehouse that fulfills an order. Specifically, by implementing the SourceSelectionInterface, developers can define custom criteria for choosing warehouses.

Let’s analyze the options:

• Option A suggests modifying AssignSourceCodeToShipmentPlugin. This plugin assigns a source code to shipments but does not handle warehouse prioritization by cost or availability. It’s not designed to sort or filter warehouses dynamically, so it doesn’t meet the requirement to pick the lowest-cost, open warehouse.

• Option B is the correct solution. By implementing SourceSelectionInterface, you gain control over the source selection process itself. You can program the logic to return only warehouses that are open on a given day, sorted by shipping cost. This allows the system to automatically select the most cost-efficient warehouse for fulfillment.

• Option C involves extending the distance-based selection algorithm. While this algorithm prioritizes proximity, it doesn’t consider cost or warehouse availability, so it’s not suitable for this use case. Sorting warehouses solely by distance won’t guarantee the lowest shipping cost.

In summary, the most effective and clean approach is to create a new class implementing the SourceSelectionInterface. This lets the architect inject custom logic for warehouse selection that factors in real-time cost and availability, fulfilling the client’s requirement. Hence, Option B is the optimal answer.

Question 6:

A merchant is operating a single website that serves both B2B and B2C customers with one store view. They want to show B2B-specific features—like negotiable quotes and credit limits—in the site header on every page for logged-in users belonging to B2B company accounts. Each B2B company has its own shared catalog and customer group, but the merchant wants this functionality without tying it to customer groups. 

What two strategies should an architect suggest to efficiently display this information while considering public data caching? (Choose two.)

A. Create a Virtual Type that switches themes when a user belongs to a B2B company so the output adapts in the alternate theme.
B. Add a new HTTP Context variable to cache separate public content for users in B2B companies, enabling output modification accordingly.
C. Store whether the current user belongs to a B2B company in the customer session and use that to adjust the output dynamically.
D. Develop a custom customer segment condition to identify B2B company users and modify the output based on this segment.
E. Determine if the logged-in user belongs to a B2B company within a block class and adjust the header output accordingly.

Correct Answers: C, E

Explanation:

The merchant’s requirement is to dynamically show B2B-specific features on the site header for users logged in under B2B company accounts, without linking this functionality directly to customer groups. Since the site supports both B2B and B2C customers in a unified environment with a single store view, the architect must suggest solutions that enable dynamic content display while preserving efficient public content caching.

Breaking down the recommended solutions:

• Option C proposes storing the user’s B2B membership status in the customer session. This method is straightforward and efficient. Using session data, the system can easily check if the logged-in user belongs to a B2B company on every request and modify the header content accordingly. It works well with caching because session data is user-specific and does not interfere with cached public content.

• Option E involves checking B2B membership status inside a block class that generates the header content. By implementing logic in the block, you can conditionally display B2B features such as negotiable quotes or credit limits. This allows dynamic rendering without modifying the entire page cache or relying on complex caching strategies.

Why other options are less suitable:

• Option A (theme switching based on user type) adds unnecessary complexity and performance overhead. Switching themes dynamically can cause caching issues and increase page load times, which is disproportionate to the requirement.

• Option B (using HTTP Context variables) could lead to caching complications since HTTP Context is generally designed to vary cache based on user-specific parameters. Overusing it for B2B identification could degrade caching efficiency and performance.

• Option D (using customer segments) is typically meant for marketing and personalization, not for core functional display logic like showing account features. It adds extra overhead and complexity without clear benefit for this scenario.

In conclusion, combining session-based data tracking (Option C) with dynamic block-level checks (Option E) is the most efficient, maintainable, and cache-friendly approach for dynamically showing B2B-specific features for logged-in users on a unified Magento website.

Question 7:

An Adobe Commerce Architect needs to adjust the workflow of a monthly installments payment extension. This extension belongs to a partner linked to the default website’s Payment Service Provider (PSP), which uses a legacy payment module. The partner only initiates the payment, while the PSP completes the capture. After a successful capture, the PSP sends a webhook to the website to create an invoice and save capture details for refunds. 

What is the simplest way for the Architect to implement this behavior?

A. Add a plugin before $invoice->capture() to prevent calling $payment->capture()
B. Set the payment method’s can_capture attribute in config.xml to <can_capture>0</can_capture>
C. Define a capture command using Magento\Payment\Gateway\Command\NullCommand in di.xml

Correct Answer: B

Explanation:

The key goal here is to stop Magento’s default payment capture behavior because the PSP takes care of capturing payments after initialization by the partner extension. Magento should only generate the invoice and record capture details once the PSP confirms the capture via the webhook.

Option A suggests intercepting the capture call by adding a plugin before the invoice capture method. Although feasible, this approach complicates the workflow unnecessarily by modifying core method behavior at runtime. It involves additional custom code and potential maintenance challenges.

Option B is the most straightforward and effective solution. By setting <can_capture>0</can_capture> in the payment method configuration, Magento disables its automatic capture functionality. This means Magento will not attempt to capture payments internally. Instead, the PSP handles the capture, and Magento only processes webhook notifications to create invoices and save capture data. This configuration-based solution is clean, minimal, and aligns perfectly with the requirements without extra customization.

Option C involves creating a NullCommand to override the capture action in the dependency injection configuration. While this also prevents capture execution, it requires more complex customization by managing command pools and command overrides, which is more intricate than the simple config change in option B.

In conclusion, setting the can_capture attribute to zero in the payment method configuration is the simplest and most maintainable approach to prevent Magento from capturing payments and allow the PSP to handle it, making B the best choice.

Question 8:

In a headless Adobe Commerce environment, how can you solve the problem of GraphQL queries returning stale data while still maintaining good performance?

A. Set the $cache directive to cacheable: false for every GraphQL query to disable caching
B. Use the @cache directive with a cacheIdentity class that assigns cache tags for relevant brands and products
C. Inject \Magento\GraphQlCache\Model\CacheableQuery in resolvers and call setCacheValidity(true) in the resolve method

Correct Answer: B

Explanation:

In a headless Adobe Commerce implementation, GraphQL is commonly used for frontend data requests. Performance is heavily reliant on caching, but when cached data becomes outdated (stale), it causes inconsistencies for users. The challenge is to keep data fresh without sacrificing cache efficiency.

Option A disables caching entirely by marking all queries as non-cacheable. While this guarantees fresh data, it significantly degrades performance because every query requires real-time data fetching, increasing server load and slowing down the user experience. Thus, it’s not ideal for scalability or responsiveness.

Option B offers a balanced solution. The @cache directive in GraphQL schema allows developers to associate cache tags through a cacheIdentity class. This class assigns specific cache tags related to the data, like brand or product tags. When data changes (e.g., a product update), these tags invalidate the cache automatically. This approach preserves caching benefits while ensuring that relevant data is refreshed precisely when needed. It optimizes both freshness and performance by leveraging smart cache invalidation.

Option C involves programmatically controlling cache validity inside the resolver with the CacheableQuery class. However, it lacks the mechanism to assign cache tags that trigger cache invalidation. Without cache tags, the system cannot selectively refresh stale content effectively, potentially causing outdated information to persist.

In summary, using the @cache directive with cache identities to tag relevant data ensures efficient cache invalidation and delivers up-to-date data without sacrificing the performance benefits of caching. Therefore, B is the optimal solution.

Question 9:

An Adobe Commerce Architect is troubleshooting a problem where some product attributes stored using the EAV model stop updating. The catalog contains 20,000 products with 100 attributes each. Regular imports run multiple times daily.

The logs show an integrity constraint error trying to insert a row with the ID 2147483647. What is causing this error?

A. Magento’s use of INSERT ON DUPLICATE KEY leads to hitting the auto-increment column limit
B. Integrity constraints were dropped during an upgrade, causing missed data validation
C. The EAV import uses REPLACE, causing the auto-increment ID column to reach its maximum value

Correct Answer: C

Explanation:

The error relates to trying to insert a row with ID 2147483647, which is the maximum value of a signed 32-bit integer. This suggests the database auto-increment column for IDs has reached its limit, causing the integrity constraint violation.

Option A discusses INSERT ON DUPLICATE KEY UPDATE, a common SQL pattern to update existing rows or insert new ones. However, this pattern does not inherently cause auto-increment overflow errors because it updates existing rows rather than continuously creating new rows that increment the ID. Therefore, it’s unlikely the cause.

Option B mentions integrity constraints being dropped after an upgrade, implying data consistency issues. But this is unrelated to hitting a maximum auto-increment value. Dropped constraints would cause different kinds of errors or data inconsistencies, not a numeric overflow for primary keys.

Option C correctly identifies that the EAV import process uses REPLACE INTO statements. REPLACE deletes an existing row and inserts a new one, which forces the database to generate a new auto-increment ID each time. When dealing with large product volumes and many attributes, this can quickly cause the ID column to reach its max value. The use of a 32-bit signed integer for the auto-increment column restricts ID values to a maximum of 2147483647, so once reached, insertions fail.

The solution involves altering the database schema to use a larger data type for the auto-increment column (e.g., BIGINT) to allow larger ID values, preventing this overflow. Additionally, reviewing the import mechanism to avoid unnecessary REPLACE operations can help reduce ID growth.

Thus, option C best explains the cause and points to the correct direction for resolution.

Question 10:

In Adobe Campaign Classic, a developer needs to automate the process of sending personalized email campaigns to different customer segments based on their recent purchase history. 

Which approach should the developer take to ensure efficient segmentation and dynamic content delivery within the workflow?

A. Create multiple email deliveries with static recipient lists for each segment.
B. Use a query activity within a workflow to segment the audience dynamically, then use dynamic content blocks in the email template.
C. Export the customer data, segment it externally, and upload separate recipient lists for each segment.
D. Use a single delivery with manual filters applied before sending.

Answer: B

Explanation:

For Adobe Campaign Classic developers, automation, segmentation, and personalized content are essential capabilities to improve campaign relevance and performance. The question asks about automating email sends targeted to different segments based on recent purchase history, while ensuring efficient segmentation and dynamic content.

Option B is the best choice because it leverages the built-in workflow capabilities of Adobe Campaign Classic. By using a query activity, the developer can dynamically filter and segment the customer database within the campaign workflow based on specific criteria like recent purchases. This approach is automated and scalable, avoiding manual intervention.

Furthermore, Adobe Campaign supports dynamic content blocks inside email templates. This allows personalized messages or offers to be displayed based on recipient data attributes, such as their purchase history or segment membership. The combination of workflow queries for segmentation and dynamic content in emails provides a seamless, efficient way to deliver tailored messages without creating multiple separate deliveries.

Option A involves creating multiple static deliveries, which is inefficient and difficult to maintain, especially if the customer data changes frequently. This approach increases manual work and risks sending outdated or irrelevant content.

Option C requires exporting and segmenting data outside Adobe Campaign and then uploading segmented lists. This adds unnecessary complexity and time delays, making the process less agile.

Option D suggests manual filters before sending a single delivery, which reduces automation and scalability and increases the risk of human error.

In summary, Option B ensures the developer can automate segmentation and personalize emails efficiently within Adobe Campaign Classic’s native workflow and template tools, making it the best practice for this use case.
