Demo Questions

Question 1
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During testing, the queries sometimes return out-of-date information.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?
  1. Specify a @cacgecacheable(cacheable: false) directive for each GraphQL query, making sure that the data returned is not cached, and is up to date
  2. Specify a $cache(cacheidentity: Path\\To\\identityclass) directive for each GraphQL query, corresponding to a class that adds cache tags for relevant brands and associated products
  3. Each GraphQL query's resolver class should inject \Magento\GraphQlcache\Model\cacheableQuery and call setcachevalidity(true) on it as part of the resolver's resolve function.
Correct answer: B
Explanation:
This solution ensures that the data returned by the GraphQL queries is up to date, while also maintaining performance. By specifying a $cache(cacheidentity: Path\To\identityclass) directive for each GraphQL query, the relevant brands and associated products will be added as cache tags.

Question 2
An Adobe Commerce Architect is investigating a case where some EAV product attributes are no longer updated.
  • The catalog is composed of 20.000 products with 100 attributes each.
  • The product updates are run by recurring Adobe commerce imports that happen multiple times a day.
  • The Architect finds an error in the logs that indicates an integrity constraint while trying to insert row with id 2147483647.
What is causing this error?
  1. Magento framework uses INSERT on DUPLICATE, which leads to reaching the max limit of the increment of the column.
  2. Integrity constraints were dropped after upgrading to the latest version, and the integrity checks were missed.
  3. EAV attribute import uses REPLACE, which leads to reaching the max limit of the increment of the column
Correct answer: C
Explanation:
EAV attribute import uses the REPLACE statement, which deletes and inserts a new row with the same primary key value. This causes the auto-increment column to increase by one for each row, even if the row already exists.If the auto-increment column reaches its maximum value, which is 2147483647 for a signed INT, then any further REPLACE statement will fail with an integrity constraint violation error.Reference:EAV and extension attributes | Magento 2 Developer DocumentationGitHub - techdivision/import-attribute: This library provides the functionality for the Magento 2 import of EAV attributesData integrity in JSON (B) when replacing EAV - Stack Overflow

Question 3
An Adobe Commerce Architect is planning to create a new action that will add gift registry items to the customer's quote. What should the Architect do to guarantee that private content blocks are updated?
  1. Mark the controller by setting no-cache HTTP headers
  2. Invalidate the status of gift registry indexers
  3. Specify a new action in a sections.xml configuration file
Correct answer: C
Explanation:
Private content blocks are sections of the page that are specific to each customer and are not cached by the server. To update these blocks when a customer performs an action, such as adding a gift registry item to the quote, the Adobe Commerce Architect needs to specify the new action in a sections.xml configuration file. This file defines which blocks need to be updated for each action and how often they should be updated. By doing this, the Architect can ensure that the private content blocks are refreshed with the latest data from the server.Reference:Private content | Magento 2 Developer DocumentationConfigure private content | Magento 2 Developer Documentation
