質問 # 24
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. Open a ticket with Adobe support.
- B. Extend their Adobe license.
- C. Modify the magento.app.yaml file.
正解：A
解説：
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.

質問 # 25
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 as a middleware for aggregating data from APIs back into Adobe Commerce.
- B. Use API Mesh to replace the existing APIs with direct GraphQL queries.
- C. Use API Mesh batching to combine multiple API requests into a single query.
正解：C
解説：
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.

質問 # 26
An Adobe Commerce Developer is approached to disable several cron jobs from a customization completed by a third-party agency. The cron jobs will eventually be enabled again once a code review of the cron jobs is complete.
Using best principles, how should the Developer action this request?
- A. Edit the schedule with a date which will never happen in the crontab.xml file.
- B. Add the schedule="* * * * *" to the <job> node in the crontab.xml file.
- C. Add the disabled="true" to the <job> node in the crontab.xml file.
正解：C
解説：
Adobe Commerce provides a configuration flag disabled="true" for cron job definitions in crontab.xml.
When set, it prevents the job from being executed, while still keeping the job definition in place. This allows developers to temporarily disable cron jobs without deleting or altering their schedules - a best practice in scenarios where the jobs will later be re-enabled.
* Option A (schedule="* * * * *") would instead run the cron job every minute, which is the opposite of disabling it.
* Option B (setting an impossible date) is a hack and not recommended, as it introduces fragile configuration that can confuse future maintainers.
* Option C is the official and proper way to disable a cron job in Adobe Commerce.
Official Documentation Extracts:
* "To disable a job, add the attribute disabled="true" to the <job> node in crontab.xml."- Adobe Commerce DevDocs: Configure cron jobs
* "You can disable a cron job without removing its definition by setting disabled="true". This is useful for temporary maintenance or debugging."- Adobe Commerce PHP Developer Guide: Cron configuration
質問 # 27
A client with a multisite Adobe Commerce installation needs to manage different prices for the same product across various storefronts due to factors like regional pricing strategies and distribution costs. The lowest level of the hierarchy is used to manage localization, including product content.
How should the catalog price scope be configured to address the client's requirements?
- A. Catalog price scope should be set to Website.
- B. Catalog price scope should be set to Global.
- C. Catalog price scope should be set to Store View.
正解：A
質問 # 28
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. Open a ticket with Adobe support.
- B. Extend their Adobe license.
- C. Modify the magento.app.yaml file.
正解：A
質問 # 29
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 patch to implement the necessary customizations.
- B. Use a preference and extend the original class.
- C. Use an observer to customize data processed by the class.
正解：B
解説：
If methods are protected or private, plugins cannot be used because they only work with public methods. In this case, the developer should use a class preference to replace the original class with a custom class that extends it.
A (preference) is correct.
B (observer) cannot be used because observers only react to events, not protected/private methods.
C (patch) is not a customization mechanism; data/patches are used for database schema or data updates.

質問 # 30
An Adobe Commerce Developer creates a before plugin for the save() method from the Magento\Framework\App\Cache\Proxy class to manipulate with cache identifiers and data before it is saved to the cache storage. An example of the code is shown below:
namespace Magento\Framework\App\Cache;
use Magento\Framework\App\Cache\CacheInterface;
use Magento\Framework\ObjectManager\NoninterceptableInterface;
class Proxy implements
CacheInterface,
NoninterceptableInterface
{
...
public function save($data, $identifier, $tags = [], $lifeTime = null)
{
return $this->getCache()->save($data, $identifier, $tags, $lifeTime);
}
...
}
Why is the plugin not working as expected?
- A. An after plugin defined for the same function affects the results.
- B. An around plugin defined for the same function prevents the execution.
- C. The plugin cannot be created for this class.
正解：C
質問 # 31
A Developer applies multiple quality patches to an Adobe Commerce Cloud store. After deployment, the Developer discovers that one of the patches is causing issues.
What is the correct procedure to safely remove or revert the problematic quality patch?
- A. Delete the quality patch from the file magento.app.yaml.
- B. Delete the quality patch from the file magento.env.yaml.
- C. Execute command in magento-cloud.php /vendor/bin/ecc-patches:revert <patch-id>.
正解：C
質問 # 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. Go to New Relic Log Management to access aggregated log data, allowing the analysis of application, infrastructure, CDN, and WAF errors.
- B. Connect via SSH into each production node to review system and application logs independently for a more accurate representation of issues being logged.
- C. Access Cloud Console to review environment messages and deployment logs that took place during the previous deployment to production.
正解：A
質問 # 33
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.
正解：C
解説：
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
質問 # 34
A Developer needs to set up a message queue topic in Adobe Commerce to asynchronously handle order processing.
Which XML file should the Developer use to configure this?
- A. queue_consumer.xml
- B. communication.xml
- C. queue_topology.xml
正解：C
質問 # 35

In this scenario, which option should the Developer implement?
- A. Use API Mesh as a middleware for aggregating data from APIs back into Adobe Commerce.
- B. Use API Mesh to replace the existing APIs with direct GraphQL queries.
- C. Use API Mesh batching to combine multiple API requests into a single query.
正解：C
質問 # 36
An Adobe Commerce Developer is implementing asynchronous communication with a third-party system using RabbitMQ. The XML files used must be able to configure a local queue and consume messages published by the third-party system.
Which files should the Developer use?
- A. queue_topology.xml and queue_publisher.xml
- B. queue_topology.xml and queue_consumer.xml
- C. communication.xml, queue_topology.xml, and queue_consumer.xml
- D. communication.xml, queue_topology.xml, and queue_publisher.xml
正解：B
解説：
To consume messages from a third-party system in RabbitMQ:
queue_topology.xml # defines queues and exchanges (topology).
queue_consumer.xml # defines consumers that listen to the queues.
A/D: communication.xml is used for defining topics for Adobe Commerce modules, not needed when consuming third-party messages directly.
C: queue_publisher.xml is used for publishing messages, not consuming them.

Adobe Commerce DevDocs - Message queues
質問 # 37
A Developer discovers that inline scripts are no longer working. This issue occurred after upgrading to the latest version of Adobe Commerce. When checking the console, the errors indicate that the scripts are not allowed to execute. The following is an example script:
<div id="action-div" onclick="someComponent('title')">Action</div>
How should the Developer adapt the script to run properly according to security practices?
- A. <?php echo $block->renderAllowedElement('<div id="action-div" onclick="someComponent(\'title\')"
>Action</div>'); ?> - B. <?php echo $secureRenderer->renderEventListenerAsTag('onclick', 'someComponent(\'title\')', '#action- div'); ?>
- C. <?php echo $escaper->renderSecureTag('<div id="action-div" onclick="someComponent(\'title\')"
>Action</div>'); ?>
正解：B
