Free AD0-E725 Practice Questions

Explore 5 free practice questions for the Adobe AD0-E725 exam and review the answers and explanations to support your preparation.

  1. Question 1

    Single answer

    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?

    • Option A:

      Use API Mesh to replace the existing APIs with direct GraphQL queries.

      Correct
    • Option B:

      Use API Mesh batching to combine multiple API requests into a single query.

      Correct
    • Option C:

      Use API Mesh as a middleware for aggregating data from APIs back into Adobe Commerce.

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: B

    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.

  2. Question 2

    Single answer

    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?

    • Option A:

      Extend their Adobe license.

      Correct
    • Option B:

      Modify the magento.app.yaml file.

      Correct
    • Option C:

      Open a ticket with Adobe support.

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: C

    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.

  3. Question 3

    Single answer

    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?

    • Option A:

      Connect via SSH into each production node to review system and application logs independently for a more

      accurate representation of issues being logged.

      Correct
    • Option B:

      Go to New Relic Log Management to access aggregated log data, allowing the analysis of application,

      infrastructure, CDN, and WAF errors.

      Correct
    • Option C:

      Access Cloud Console to review environment messages and deployment logs that took place during the

      previous deployment to production.

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct 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.

    [Reference:, , Adobe Commerce Cloud DevDocs – Log management with New Relic, ]

  4. Question 4

    Multiple answers

    A customer asks for a new functionality which will allow them to see the total lifetime sales statistic of a product. This new data is to be made available for the API and traditional product exports. The technical architect of the company servicing the client decides that for this to be achieved, the first step is for an Extension Attribute to be created.

    What are the next two steps that need to be taken? (Choose two.)

    • Option A:

      Declare the extension attribute in etc/webapi_rest/extension_attributes.xml.

      Correct
    • Option B:

      Implement an around plugin on the Product Repository.

      Correct
    • Option C:

      Declare the extension attribute in etc/extension_attributes.xml.

      Correct
    • Option D:

      Implement an after plugin on the Product Repository.

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: C, D

    Explanation

    To expose a new field via an Extension Attribute:

    C → Declare the extension attribute in etc/extension_attributes.xml.

    D → Implement an after plugin on the Product Repository to populate the new attribute with custom logic (in this case, lifetime sales).

    A is incorrect: etc/webapi_rest/extension_attributes.xml does not exist (only extension_attributes.xml is valid).

    B is incorrect: around plugins are discouraged here and unnecessarily complicate service contract extensions.

    [Reference:, , Adobe Commerce DevDocs – Extension attributes]

  5. Question 5

    Single answer

    In an Adobe Commerce store, there is a product attribute called external_service_id. A Developer must ensure the attribute is

    only available for specific users via the API.

    How should the Developer achieve the required permissions?

    • Option A:

      Configure the access control list (ACL) resource for the external_service_id attribute via

      etc/extension_attributes.xml.

      Correct
    • Option B:

      Setup a custom permission control at the attribute level because it is not supported out of the box.

      Correct
    • Option C:

      Implement an afterGet plugin and exclude the attribute for non-authorized users.

      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: B

    Explanation

    Out of the box, Adobe Commerce does not support per-attribute ACL permissions. ACL resources can restrict access to API endpoints or modules, but not individual product attributes.

    Therefore, to restrict access to a specific attribute like external_service_id, the developer must implement custom permission control logic.

    A is incorrect: ACL works at module/controller/service contract level, not per attribute.

    C (plugin) could work but is not the correct principle-driven answer, as it is a workaround rather than attribute-level permission management.

    [Reference:, , Adobe Commerce DevDocs – API ACL and permissions, , Official note: Attribute-level ACL is not supported natively and requires custom implementation.]
