NEW QUESTION # 25
An Adobe Commerce Developer is tasked with adding a custom tax calculation to the checkout process. In addition to core tax calculations, a legacy code extending core tax calculation classes is also found. The Developer wants to utilize Magento's dependency injection system effectively to meet requirements, ensuring the solution works without modifying the existing core and legacy classes.
What should the Developer implement to achieve this?
- A. Virtual types
- B. Constructor arguments
- C. Preferences
Answer: A
NEW QUESTION # 26
A Developer is tasked with creating a new index. The custom indexer is not automatically updating the product data.
How should the Developer solve this issue?
- A. Use an event observer to monitor data changes.
- B. Implement custom database triggers.
- C. Use the mview to allow tracking database changes.
Answer: C
Explanation:
Magento uses the materialized view (mview) system to track database changes and trigger automatic updates to indexers.
B (mview) is correct because it enables Magento to automatically detect data changes and update indexers incrementally.
A (observer) is not reliable for large indexing operations and not the recommended method.
C (database triggers) are discouraged and not used in Magento's indexing mechanism.

NEW QUESTION # 27
A Developer is working on an Adobe Commerce store, and the security team has flagged certain inline scripts in the store as vulnerable to potential attacks. The Developer decides to implement Content Security Policies (CSP) to secure the store's environment.
What will the Developer achieve by taking this action?
- A. Ensure that all user input is sanitized before being processed by the application.
- B. Prevent users from accessing certain areas of the website based on their IP address.
- C. Restrict which resources (scripts, styles, images) are allowed to load on the website.
Answer: C
Explanation:
Comprehensive and Detailed Explanation (with official references):
The correct answer is C. Restrict which resources (scripts, styles, images) are allowed to load on the website.
Adobe Commerce supports Content Security Policy (CSP), a browser-level security feature that mitigates certain types of attacks such as Cross-Site Scripting (XSS) and data injection attacks.
By defining a CSP in Adobe Commerce, developers can control:
* Which scripts can be executed (script-src).
* Which stylesheets can be applied (style-src).
* Which images and media can be loaded (img-src, media-src).
* Whether inline scripts or styles are allowed.
This does not sanitize user input (A) nor restrict user access based on IP addresses (B). Instead, it focuses on restricting the sources of content that the browser can load.
Official Documentation Extracts:
* "Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross-Site Scripting (XSS) and data injection attacks. CSP works by restricting the sources from which content can be loaded."- Adobe Commerce DevDocs: Content Security Policy
* "A CSP allows developers to define approved sources of content that browsers can load. These policies help reduce the risk of malicious content injection in Magento storefronts."- Adobe Commerce Security Guide
NEW QUESTION # 28
A Developer is notified that custom API results are not cached, which is causing additional delays.
What are two potential causes for this behavior? (Choose two.)
- A. The request is using HTTP HEAD.
- B. The request is using HTTP GET.
- C. The request is using HTTP POST.
- D. The request is using HTTP PUT.
Answer: C,D
Explanation:
Adobe Commerce API caching (including GraphQL and REST) works only for idempotent requests such as HTTP GET.
C (POST) and D (PUT) are not cacheable because they are used for creating or updating resources.
A (GET) is cacheable.
B (HEAD) is technically idempotent, but not commonly used in Adobe Commerce APIs.
Reference:
Adobe Commerce DevDocs - Web API caching
HTTP/1.1 RFC 7231 - Cacheable methods
NEW QUESTION # 29
An Adobe Commerce Cloud client alerts a Developer to an issue with their website going down during deployments.
What should the Developer do to solve this problem?
- A. In the cloud app configuration YAML file, the deployment strategy must be defined in the global phase.
- B. From the Adobe Commerce Cloud console, the zero downtime deployment checkbox must be selected for the project.
- C. In the cloud env configuration YAML file, the static content deploy strategy must be defined in the build phase.
Answer: C
Explanation:
Adobe Commerce Cloud deployments can cause downtime if static content deployment happens during the deploy phase (when the site is live).
The recommended best practice is to move static content deployment to the build phase by configuring it in magento.env.yaml. This ensures static assets are generated before deployment, enabling zero-downtime deployments.
A is incorrect: deployment strategies belong in magento.env.yaml, not the global app YAML file.
B is incorrect: there is no such checkbox in the Cloud console.
C is correct and aligns with Adobe best practices.

Adobe Commerce Cloud DevDocs - Zero downtime deployment
NEW QUESTION # 30
A client is setting up an Adobe Commerce B2B store and wants to start offering a Payment on Account option for their customers when placing orders.
How should the Developer achieve this?
- A. Repurpose the native Cash on Delivery method.
- B. Install and activate the native Adobe Commerce module which activates payment.
- C. Create and implement a new Payment Method to provide credit accounts to customers.
Answer: B
Explanation:
Adobe Commerce B2B includes a native "Payment on Account" module, which is part of the B2B suite. This module allows customers with company accounts to place orders on account (credit).
A (repurpose COD) is a hack and not recommended.
C (create new payment method) is unnecessary since Adobe Commerce already includes this B2B feature.
B is correct: simply enable the native B2B Payment on Account module.

NEW QUESTION # 31
A client receives an alert stating that storage on their production environment is nearly full. They are using Pro architecture and are concerned about storage capacity. A Developer is asked to increase the disk size.
How should this problem be solved?
- A. Extend their Adobe license.
- B. Open a ticket with Adobe support.
- C. Modify the magento.app.yaml file.
Answer: B
Explanation:
In Adobe Commerce Cloud Pro environments, disk allocation is provisioned at the infrastructure level and cannot be changed directly by developers. Increasing disk size requires assistance from Adobe's Cloud Ops team via a support ticket.
A (license extension) is unrelated to storage.
B (magento.app.yaml) configures services and resources but cannot increase allocated disk space.
C is correct: Adobe support ticket is required.

NEW QUESTION # 32
An Adobe Commerce Cloud Developer is tasked with investigating slow page loads and intermittent errors reported by a client after a recent deployment to their Pro Production environment.
Which action should the Developer use to quickly access and analyze the necessary data?
- A. Access Cloud Console to review environment messages and deployment logs that took place during the previous deployment to production.
- B. Go to New Relic Log Management to access aggregated log data, allowing the analysis of application, infrastructure, CDN, and WAF errors.
- C. Connect via SSH into each production node to review system and application logs independently for a more accurate representation of issues being logged.
Answer: B
NEW QUESTION # 33
A third-party company wants to integrate into Adobe Commerce by using webhooks; they would like to emulate the webhook endpoint. As part of this process, they will send payload data to a Developer for testing.
What format should the payload be as part of the webhook test command?
- A. Plain text
- B. JSON
- C. XML
Answer: B
NEW QUESTION # 34
An Adobe Commerce Expert is tasked with implementing a custom condition on salable quantity with reservations. The condition needs to be applicable only when added to cart.
Which option should the Developer implement?
- A. <preference for="
Magento\InventorySales\Model\IsProductSalableForRequestedQtyCondition\IsSalableWithReservationsC type=" Vendor\InventorySales\Model\IsProductSalableForRequestedQtyCondition\IsSalableWithReservationsCo
/> - B. <type name="Magento\InventoryApi\Model\Stock\ValidatorChain">
<arguments>
<argument name="validators" xsi:type="array">
<item name="is_salable_with_reservations" xsi:type="object"
>Vendor\InventorySales\Model\Stock\Validator\IsSalableWithReservationsValidator</item>
</argument>
</arguments>
</type> - C. <virtualType name="IsProductSalableForRequestedQtyConditionChainOnAddToCart">
<arguments>
<argument name="conditions" xsi:type="array">
<item name="is_salable_with_reservations" xsi:type="array">
<item name="object" xsi:type="object"
>Vendor\InventorySales\Model\IsProductSalableForRequestedQtyCondition\IsSalableWithReservationsC
/item>
</item>
</argument>
</arguments>
</virtualType>
Answer: C
Explanation:
To add a custom salable quantity condition for use only during the add-to-cart flow, developers must extend the IsProductSalableForRequestedQtyConditionChainOnAddToCart virtual type. This chain is designed specifically for cart validation, ensuring the new condition runs only at that stage.
A would override the core class completely, not scoped to add-to-cart.
B relates to stock validator chains, not salable quantity conditions.
C is correct: defining a virtual type extension ensures proper conditional logic for reservations during cart validation.

Adobe Commerce DevDocs - MSI salable quantity conditions
NEW QUESTION # 35
A Developer discovers the following code snippet in default.xml layout:
<referenceBlock name="content">
<block name="custom" template="example.phtml" cacheable="false" />
</referenceBlock>
Which caching behavior will occur?
- A. The content block and all its child blocks will become cacheable.
- B. Only the custom block will not be cached.
- C. All pages will be marked as non-cacheable.
Answer: C
Explanation:
In Magento, if any block within the page layout is marked cacheable="false", the entire page becomes non- cacheable. This means that full-page caching (FPC) will be disabled for all pages containing that block.
Option A is incorrect: cacheability is applied at the page level, not per block.
Option C is misleading; cacheable blocks remain cacheable only if no non-cacheable blocks are present.

Adobe Commerce DevDocs - Full-page caching
NEW QUESTION # 36
A recent client-reported bug is fixed by the Adobe Commerce community. The Adobe engineering team has not yet released the patch or committed the bug fix to GitHub. A Developer acquires the custom patch and releases it to their Adobe Commerce environments.
What are the recommended steps the Developer should follow to implement the custom patch for the bug fix?
- A. Install only official patches supplied by them to maintain upgradability.
- B. Install the cweagans/composer-patches module and edit the composer.json file to apply the custom patch.
- C. Update the quality-patches module and list the required patch in the magento-ce-patch.yaml file.
Answer: B
NEW QUESTION # 37
A Developer using API Mesh is assigned to optimize the integration of several third-party APIs with Adobe Commerce. Part of this task is to address performance issues such as the n+1 problem.
In this scenario, which option should the Developer implement?
- A. Use API Mesh batching to combine multiple API requests into a single query.
- B. Use API Mesh as a middleware for aggregating data from APIs back into Adobe Commerce.
- C. Use API Mesh to replace the existing APIs with direct GraphQL queries.
Answer: A
Explanation:
The n+1 problem occurs when multiple queries are made individually instead of being grouped, leading to inefficient performance.
API Mesh batching solves this by combining multiple GraphQL requests into a single query, reducing round trips and improving response times.
A is incorrect: API Mesh does not "replace" APIs but orchestrates them.
C is partially correct but too general; aggregation alone does not solve the n+1 problem.
B is correct: batching specifically addresses n+1 query performance issues.

NEW QUESTION # 38
While implementing additional functionality, a Developer needs to modify a class with protected and private methods requiring custom logic. The Developer finds that no other Magento customization, such as plugins, will work.
What should the Developer do in this scenario?
- A. Use a preference and extend the original class.
- B. Use a patch to implement the necessary customizations.
- C. Use an observer to customize data processed by the class.
Answer: A
NEW QUESTION # 39
A Developer is integrating a custom third-party gift card system into the Adobe Commerce checkout. During checkout, a customer enters a store-bought gift card for payment, and depending on external API checks, the gift card is verified and allowed to be used on the order.
Which approach should be used for the internal processing of such functionality?
- A. Create an Adobe Commerce gift card account and manage the account using the gift card repositories.
- B. Create a unique voucher code for each gift card usage request which grants a discount on the order's total.
- C. Directly subtract the gift card amount from the order, keeping no history of the discount transaction.
Answer: B
Explanation:
The correct way to integrate external gift cards is to generate a unique discount (voucher code) that maps to the validated gift card value. This approach ensures that the transaction is recorded in Magento's discount system, preserving order and accounting integrity.
A is incorrect because Adobe Commerce gift card accounts are native to the Commerce Gift Card module and not applicable to external systems.
C is incorrect as directly subtracting amounts without transaction history violates best practices and auditability.
B is correct: mapping external validation into a voucher/discount ensures proper tracking.

NEW QUESTION # 41
An Adobe Commerce Cloud Developer is tasked with investigating slow page loads and intermittent errors reported by a client after a recent deployment to their Pro Production environment.
Which action should the Developer use to quickly access and analyze the necessary data?
- A. Access Cloud Console to review environment messages and deployment logs that took place during the previous deployment to production.
- B. Go to New Relic Log Management to access aggregated log data, allowing the analysis of application, infrastructure, CDN, and WAF errors.
- C. Connect via SSH into each production node to review system and application logs independently for a more accurate representation of issues being logged.
Answer: B
Explanation:
In Adobe Commerce Cloud Pro Production, logs are spread across multiple nodes, so manually checking each node (A) is inefficient. The correct approach is to use New Relic Log Management, which aggregates logs from all services and nodes. This allows developers to quickly analyze application logs, infrastructure logs, CDN, and WAF errors in one place.
A is inefficient and not recommended.
C only shows deployment logs, not ongoing runtime errors.
B is correct: New Relic Log Management is the single source of truth for performance and error analysis.

NEW QUESTION # 42
A Developer working on a Magento 2 store needs to modify the Content Security Policy (CSP) to allow loading of images from a trusted external domain while maintaining strict policies for other resources. To accomplish this, the csp_whitelist.xml file must be updated.
Which code snippet should the Developer use to update the CSP configuration?
- A. <csp>
<policies>
<policy id="media-src">
<values>
<value id="trusted_image" type="host">website.com</value>
</values>
</policy>
</policies>
</csp> - B. <policies>
<policy id="default-src">
<values>
<value id="trusted_image" type="host">website.com</value>
</values>
</policy>
</policies> - C. <policies>
<policy id="img-src">
<values>
<value id="trusted_image" type="host">website.com</value>
</values>
</policy>
</policies>
Answer: C
Explanation:
To allow loading of external images, the policy that must be updated is img-src in the csp_whitelist.xml.
Option A (default-src) is too broad and not best practice.
Option C (media-src) applies only to audio/video sources, not images.
Thus, B is the correct solution.

NEW QUESTION # 43
A recent client-reported bug is fixed by the Adobe Commerce community. The Adobe engineering team has not yet released the patch or committed the bug fix to GitHub. A Developer acquires the custom patch and releases it to their Adobe Commerce environments.
What are the recommended steps the Developer should follow to implement the custom patch for the bug fix?
- A. Install only official patches supplied by them to maintain upgradability.
- B. Install the cweagans/composer-patches module and edit the composer.json file to apply the custom patch.
- C. Update the quality-patches module and list the required patch in the magento-ce-patch.yaml file.
Answer: B
Explanation:
If a bug fix patch has not yet been officially released by Adobe (via Quality Patches Tool (QPT)), developers can apply custom patches using the cweagans/composer-patches package.
Option A is best practice in general, but in urgent scenarios, custom patches are allowed.
Option B applies only for official Adobe patches distributed via QPT, not for community-supplied or custom fixes.
Option C is correct: cweagans/composer-patches allows applying custom patches via composer.json until an official fix is available.
