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During testing, the queries sometimes return out-of-date information.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?

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.

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.

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?
