BModify method PHPDoc and change annotation @magentoDbIsolation to enabled

CCreate Customer_ProductType: :Test/_files/{fixture_name)_rollback.php for every fixture

The solution is to modify the method PHPDoc and change the annotation @magentoDbIsolation to enabled.This will ensure that the database storage is fully cleaned after the test is run.Reference: https://developer.adobe.com/commerce/testing/guide/integration/#database-isolation1

Question No. 2

A company wants to build an Adobe Commerce website to sell their products to customers in their country. The taxes in their country are highly complex and require customization to Adobe Commerce. An Architect is trying to solve this problem by creating a custom tax calculator that will handle the calculation of taxes for all orders in Adobe Commerce.

Following best practices, how should the Architect add the taxes for all orders?

AAdd a new observer to the event sales.quote.collecLtotals.before'' and add the custom tax to the quote

BWrite a before plugin to \Magento\Quote\Model\QuoteManagement::placeOrder() and add the custom tax to the quote

CDeclare a new total collector in 'etc/sales.xmr in a custom module

Show Answer

Correct Answer: C

According to the Adobe Commerce documentation, the best way to add a custom tax calculation to all orders is to declare a new total collector in the ''etc/sales.xml'' file of a custom module. This way, the custom tax logic can be implemented in a separate class that extends the \Magento\Quote\Model\Quote\Address\Total\AbstractTotal class and overrides the collect() and fetch() methods. The collect() method is responsible for calculating the tax amount and adding it to the quote address, while the fetch() method is responsible for displaying the tax amount in the cart and checkout pages. The new total collector can be assigned to any area of the order totals, such as before or after the subtotal, shipping, or grand total.

Question No. 3

A custom cron job has been added to an Adobe Commerce system to collect data for several reports. Its crontab. xml configuration is as follows:

The job is data intensive and runs for between 20 and 30 minutes each night.

Within a few days of deployment, it is noticed that the sites sitemap. xml file has not been updated since the new job was added.

What should be done to fix this issue?

AChange the schedule of the siten.aP_generate cron job to 30 0 * * *so that it runs after the gather_reporting_data job has completed.

BCreate a new cron group for the reporting job, specifying <use_separate_process>i</use_separate_process>

CBreak the data gathering job into a number of smaller jobs, so that each individual job runs for a maximum of 5 minutes

Show Answer

Correct Answer: B

The issue here is that the gather_reporting_data job is running for a long time and blocking the sitemap_generate job from running. The solution is to create a new cron group for the reporting job and specify <use_separate_process>i</use_separate_process> so that the reporting job runs in a separate process and does not block the sitemap_generate job.Reference: https://experienceleague.adobe.com/docs/commerce-cloud-service/user-guide/architecture/starter-architecture.html?lang=en#cron-groups-and-processes

Question No. 4

A merchant notices that product price changes do not update on the storefront.

The index management page in the Adobe Commerce Admin Panel shows the following:

* All indexes are set to 'update by schedule'

* Their status is 'ready'

* There are no items in the backlog

* The indexes were last updated 1 minute ago

A developer verifies that updating and saving product prices adds the relevant product IDs into the catalog_product_price_cl changelog table. Which two steps should the Architect recommend to the developer to resolve this issue? (Choose two.)

AReduce the frequency of the cron job to 5 minutes so the items have more time to process.

BMake sure that no custom or third-party modules modify the changelog and indexing process.

CMake sure that the version_id for the price indexer in the mview_state table is not higher than the last entry for the same column in the changelog table and re-synchronize.

DInvalidate the catalog_Product_price indexer in the Adobe Commerce Admin Panel so that it is fully reindexed next time the cron runs.

EManually reindex the catalog_product_price index from the command line: bin/magento indexer:reindex catalog_product_price.

Show Answer

Correct Answer: B, C

The issue here is that the product price changes are not reflected on the storefront, even though the indexes are set to update by schedule and there are no items in the backlog. This indicates that there might be some problem with the changelog and indexing process, which are responsible for tracking and applying the data changes to the index tables. Therefore, the Architect should recommend the developer to check if any custom or third-party modules interfere with the changelog and indexing process, and disable or fix them if needed. Additionally, the Architect should recommend the developer to verify that the version_id for the price indexer in the mview_state table is consistent with the last entry for the same column in the changelog table, and re-synchronize them if they are out of sync.This will ensure that the indexer can process all the data changes correctly and update the index tables accordingly.Reference: https://experienceleague.adobe.com/docs/commerce-admin/systems/tools/index-management.html?lang=en#cron-groups-and-processes1https://devdocs.magento.com/guides/v2.4/extension-dev-guide/indexing.html#m2devgde-mview2

Question No. 5
