An Adobe Commerce Architect is creating a new GraphQL API mutation to alter the process of adding configurable products to the cart. The mutation accepts configurable product ID. If the given product has only one variant, then the mutation should add this variant to the cart and return not nullable Cart type. If the configurable product has more variants, then the mutation should return not nullable ConfigurableProduct type.
The mutation declaration looks as follows:

How should the Adobe Commerce Architect declare output of this mutation?

An Architect working on a headless Adobe Commerce project creates a new customer attribute named my_attribute. Based on the attribute value of the customer, the results of GraphQl queries are modified using a plugin. The frontend application is communicating with Adobe Commerce through Varnish by Fastly, which is already caching the queries that will be modified. The Adobe Commerce Fastly extension is installed, and no other modifications are made to the application.
Which steps should the Architect take to make sure the vcl_hash function of Varnish also considers the newly created attribute?

An Architect needs to integrate an Adobe Commerce store with a new Shipping Carrier. Cart data is sent to the Shipping Carrier’s API to retrieve the price and display to the customer. After the feature is implemented on the store, the API hits its quota and returns the error “Too many requests”. The Shipping Carrier warns the store about sending too many requests with the same content to the API.
In the carrier model, what should the Architect change to fix the problem?

An Adobe Commerce Architect designs a data flow that contains a new product type with its own custom pricing logic to meet a merchant requirement.
Which three developments are valid when reviewing the implementation? (Choose three.)

An external system integrates functionality of a product catalog search using Adobe Commerce GraphQL API. The Architect creates a new attribute my_attribute in the admin panel with frontend type select.
Later, the Architect sees that ProductInterface already has the field my_attribute, but returns an Int value. The Architect wants this field to be a new type that contains both option id and label.
To meet this requirement, an Adobe Commerce Architect creates a new module and file etc/schema.graphqls that declares as follows:

After calling command setup:upgrade, the introspection of ProductInterface field my_attribute remains Int.
What prevented the value type of field my_attribute from changing?

An Adobe Commerce Architect needs to log the result of a ServiceClass::getData method execution after all plugins have executed. The method is public, and there are a few plugins declared for this method. Among those plugins are after and around types, and all have sortOrder specified.
Which solution should be used to meet this requirement?

A company has an Adobe Commerce store. An attribute named “my_attribute” (type “text”) is created to save each product’s global ID that is shared between multiple systems.
Several months after going live, the values of “my_attribute” are all integer. This causes a problem for the other systems when those systems receive this data.
An Adobe Commerce Architect needs to recommend a solution to change the type of “my_attribute” from text to int.
Which two steps should the Architect take to achieve this? (Choose two.)

A merchant is using a unified website that supports native Adobe Commerce B2B and B2C with a single store view.
The merchant wants to show the B2B account features like negotiable quotes and credit limits in the header of the site on every page for the logged-in users who are part of a B2B company account.
Each B2B company has its own individual shared catalog and customer group, and many customer groups for non B2B customers change. The merchant requests that this should not be tied to customer groups.
Which two solutions should the Architect recommend considering public data and caching? (Choose two.)

A representative of a small business needs an Adobe Commerce Architect to design a custom integration of a third-party payment solution. They want to reduce the list of controls identified in their Self-Assessment Questionnaire as much as possible to achieve PCI compliance for their existing Magento application.
Which approach meets the business needs?

An Architect is reviewing a custom module that is logging customer activity data on storefront using observers. The client reports that logs were recorded while the client was previewing storefront catalog pages from Admin Panel for a future scheduled campaign, using Adobe Commerce staging preview functionality.
What should the Architect check first to address this issue?

An existing Adobe Commerce website is moving to a headless implementation.
The existing website features an “All Brands” page, as well as individual pages for each brand. All brand-related pages are cached in Varnish using tags in the same manner as products and categories.
Two new GraphQL queries have been created to make this information available to the frontend for the new headless implementation:

During testing, the queries sometimes return out-of-date information.
How should this problem be solved while maintaining performance?

An Adobe Commerce Architect needs to create a new customer segment condition to enable admins to specify an ‘Average sales amount’ condition for certain segments.
The Architect develops the custom condition under Vendor\Module\Model\Segment\Condition\AverageSalesAmount with all of its requirements:

During testing, the following error appears:

Which two steps should the Architect complete to fix the problem? (Choose two.)

While reviewing a newly developed pull request that refactors multiple custom payment methods, the Architect notices multiple classes that depend on \Magento\Framework\Encryption\EncryptorInterface to decrypt credentials for sensitive data.
The code that is commonly repeated is as follows:

In each module, the user_secret config is declared as follows:

The Architect needs to recommend an optimal solution to avoid redundant dependency and duplicate code among the methods.
Which solution should the Architect recommend?

Due to a marketing campaign, a website is experiencing a very large number of simultaneously placed orders, which is affecting checkout performance. The website is in the production deploy mode.
Which two website settings can an Architect optimize to decrease the impact on checkout performance? (Choose two.)

An Adobe Commerce Architect is setting up a Development environment for an on-premises project that will be used for developers to specifically test functionality, not performance, before being passed to the Testing team.
The Magento application must run with the following requirements:

1. Errors should be logged and hidden from the user
2. Cache mode can only be changed from Command Line
3. Static files should be created dynamically and then cached
   Which Application Mode is required to achieve this?

An Adobe Commerce Architect needs to ensure zero downtime during the deployment process of Adobe Commerce on-premises.
Which two steps should the Architect follow? (Choose two.)

An Architect needs to review a custom product feed export module that a developer created for a merchant. During final testing before the solution is deployed, the product feed output is verified as correct. All unit and integration tests for code pass.
However, once the solution is deployed to production, the product price values in the feed are incorrect for several products. The products with incorrect data are all currently part of a content staging campaign where their prices have been reduced.
What did the developer do incorrectly that caused the feed output to be incorrect for products in the content staging campaign?

An Adobe Commerce Architect is asked by a merchant using B2B features to help with a configuration issue.
The Architect creates a test Company Account and wants to create Approval Rules for orders. The Approval Rules tab does not appear in the Company section in the Customer Account Menu when the Architect logs in using the Company Administrator account.
Which two steps must be taken to fix this issue? (Choose two.)

An Adobe Commerce Architect gets a request to change existing payment gateway functionality by allowing voided transactions only for a certain range of paid amounts.
In the vendor module file etc/config.xml, payment method has an option can_void set to 1.
How should this customization be done?
