NEW QUESTION # 27
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.)
- A. Enable Config flag Under developer/zero_down_time/enabled
- B. Run bin/magento setup:upgrad --convert-old-scripts-true to Upgrade database
- C. Run bin/magento setup:upgrade --dry-run=true to upgrade database
- D. Enable Config flag Under deployement/blue_green/enabled
- E. Run bin/magento setup:upgrade - -keep-generated to Upgrade database
Answer: D,E
Explanation:
Explanation
Option A is correct because enabling the config flag under deployment/blue_green/enabled is one of the steps to ensure zero downtime during the deployment process of Magento 2 on-premises. This flag enables the blue-green deployment feature, which allows deploying a new version of the Magento application to a separate environment (blue) without affecting the current live environment (green). Once the new version is ready, the traffic can be switched from green to blue with minimal or no downtime1.
Option C is correct because running bin/magento setup:upgrade --keep-generated is another step to ensure zero downtime during the deployment process of Magento 2 on-premises. This command updates the database schema and data without deleting the generated code and static view files. This way, the Magento application can still serve requests from the cache while the database is being upgraded2.
Option B is incorrect because running bin/magento setup:upgrade --dry-run=true does not upgrade the database, but only checks if there are any errors or conflicts in the database schema or data. This command can be used for testing purposes, but it does not affect the deployment process or the downtime3.
Option D is incorrect because there is no such option as --convert-old-scripts-true for the bin/magento setup:upgrade command. This option does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.
Option E is incorrect because there is no such config flag as developer/zero_down_time/enabled in Magento 2. This flag does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.

NEW QUESTION # 28
A single Adobe Commerce Cloud instance is set up with two websites (each with a single store view) with different domains.
* The default website is website_one, with store view store_one, and domain storeone. com.
* The second website is website_two, with store view store_two, and domain storetwo. com.
The magento-vars. php file is set up as follows to determine which website each request runs against:
When testing a new GraphQL integration, all requests returned data relating to the default website, regardless of the domain. What is causing this issue?
- A. $_server["mage_run_cooe") needs to be setto store and *$_SERVER["MAGE_RUN_TYPE"] needs to be set to the store code instead.
- B. The magento-vars.php file is not processed for any GraphQL requests, so the default website is always processed.
- C. GraphQL requests are always run against the default store view unless a store header or store cookie is provided.
Answer: C
Explanation:
Explanation
The magento-vars.php file is used to set the website or store view based on the HTTP host, but it does not affect GraphQL requests. GraphQL requests are handled by a separate controller that does not use the magento-vars.php file. Instead, GraphQL requests use the default store view of the default website, unless a store header or store cookie is provided in the request. The store header or cookie should contain the store code of the desired store view. For example, to query data from website_two, the request should include a header like store: store_two or a cookie like store=store_two12.

NEW QUESTION # 29
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?
- A. The developer retrieved product data directly from the database using the entity_id column rather than a collection or repository.
- B. The developer did not check for an active content staging campaign and emulates the campaign state when retrieving product data.
- C. The developer forgot to use the getContentStagingValue method to retrieve the active campaign value of the product data.
Answer: B
Explanation:
Explanation
Option C is correct because the developer did not check for an active content staging campaign and emulate the campaign state when retrieving product data. Content staging campaigns can modify the product data such as price, name, description, and so on, based on a schedule. To get the correct product data for a specific date and time, the developer needs to use the Magento\Staging\Model\VersionManager class to set the current version ID and emulate the campaign state1. Otherwise, the product data will be retrieved from the default store view without applying the campaign changes.
Option A is incorrect because retrieving product data directly from the database using the entity_id column is not necessarily wrong. It may not be the best practice, but it does not cause the feed output to be incorrect for products in the content staging campaign. The content staging campaigns are stored in separate tables with a version ID that links to the main product table2. The developer can still join these tables and query the product data based on the version ID and date.
Option B is incorrect because there is no such method as getContentStagingValue in Magento 2. The developer cannot use this method to retrieve the active campaign value of the product data. The correct way to get the product data for a specific campaign is to use the Magento\Staging\Model\VersionManager class as mentioned above.

NEW QUESTION # 30
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?
- A. Utilize the Advanced Encryption standard (aes-256) algorithm to encrypt all customer-sensitive data from the payment module.
- B. Utilize the payment provider iframe system to isolate content of the embedded frame from the parent web page.
- C. Utilize a trusted signed certificate issued by a Certification Authority (CA) to secure each connection made by the payment solution protocol via https.
Answer: B
Explanation:
Explanation
Using an iframe system for payment integration can help reduce the PCI scope and compliance burden for the merchant, as the payment data is collected and processed by the payment service provider (PSP) within the iframe, without touching the merchant's website or server. This way, the merchant can leverage the PSP's PCI certification and avoid storing or transmitting any sensitive cardholder data on their own system. The iframe also provides a secure barrier between the host webpage and the loaded page, preventing any access or manipulation of the payment data by malicious actors. To implement this approach, the merchant needs to embed the PSP's payment form in their checkout page using an iframe element, and configure the communication between the iframe and the host page using JavaScript123.
NEW QUESTION # 31
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?
- A. Integrity constraints were dropped after upgrading to the latest version, and the integrity checks were missed.
- B. EAV attribute import uses REPLACE, which leads to reaching the max limit of the increment of the column
- C. Magento framework uses INSERT on DUPLICATE, which leads to reaching the max limit of the increment of the column.
Answer: B
Explanation:
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. References:

NEW QUESTION # 32
A third-party company needs to create an application that will integrate the Adobe Commerce system to get orders data for reporting. The integration needs access to the GET /Vl/orders endpoint. It will call this endpoint automatically every hour around the clock. The merchant wants the ability to restrict or extend access to resources as well as to revoke the access using Admin Panel.
Which type of authentication available in Adobe Commerce should be used and implemented in a third-party system for this integration?
- A. Use token-based authentication to obtain the Admin Token. The third-party system will utilize the REST endpoint using the admin username and password to get the Admin Token, which will be used as the Bearer Token to authorize.
- B. Use token-based authentication to obtain an integration Token, integration will be created and activated in the admin panel using default integration token settings to get access to the token, which will be used as the Bearer Token to authorize.
- C. Use OAuth-based authentication to provide access to system resources. Integration will be registered by the merchant in the admin panel with an OAuth handshake during activation. The third-party system should follow OAuth protocol to authorize.
Answer: C
Explanation:
Explanation
According to the Adobe Commerce documentation, OAuth-based authentication is the recommended method for integrations that need access to system resources, such as orders, customers, products, etc. OAuth-based authentication allows the merchant to control the access level and scope of the integration, as well as to revoke the access at any time using the admin panel. OAuth-based authentication also requires an OAuth handshake between the integration and the Adobe Commerce system during activation, which ensures a secure exchange of tokens and keys. The third-party system should follow the OAuth protocol to obtain and refresh the access token, which will be used as the Bearer Token to authorize the REST API calls.

NEW QUESTION # 33
An Adobe Commerce Architect designs and implements functionality that introduces a new Complex Product Type to the existing Adobe Commerce website. Besides visual demonstration of the new product type, the changes include adjustments to the price index.
The website utilizes a multi-dimensional indexer feature to store the price index. The Architect decides to cover it with integration tests. After creating and running one test, the Architect discovers that database storage is not being fully cleaned.
The test method has the following annotation declaration:
Which adjustment should the Architect make to fix this issue?
- A. Modify method PHPDoc and change annotation @magentoDbIsolation to enabled
- B. Add annotation @magentoApplsolation enabled to method PHPDoc
- C. Create Customer_ProductType: :Test/_files/{fixture_name)_rollback.php for every fixture
Answer: A
Explanation:
Explanation
The issue here is that the database storage is not being fully cleaned after the test is run. 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. References:

NEW QUESTION # 34
An Architect needs to create an additional regional UK website with its own website currency set to GBP in Adobe Commerce. An existing US website is using USD as a default base and website currency.
After the first week of sales in the new UK website, an administrator notices that all sales totals in Sales Orders report show £0.00.
How should this issue be resolved?
- A. Configure currency rates for GBP and USD, so they are not empty.
- B. Refresh Lifetime Statistics for "Total Invoiced'.
- C. Make sure that orders are shipped and not left in processing state.
Answer: A
Explanation:
Explanation
The issue here is that the sales totals in Sales Orders report show £0.00 for the new UK website. This is because the currency rates for GBP and USD are not configured, so the system cannot convert the order amounts from GBP to USD. The solution is to configure the currency rates for GBP and USD, so they are not empty. This will allow the system to calculate the sales totals in USD for the report. References:

NEW QUESTION # 35
An Architect is configuring the preload.keys for Redis on an Adobe Commerce on-premise instance.
The Architect discovers that the following cache keys are loaded on each frontend request:
EAV_ENTITY_TYPES, GLOBAL_PLUGIN_LIST, DB_IS_UP_TO_DATE, SYSTEM_DEFAULT.
* The id_prefix of the frontend => page_cache is set to 063_.
* The id_pref ix of frontend => default is set to 762_.
* The Architect has enabled and configured Redis L2 caching.
How should the preload.keys be configured?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Explanation
Option C is correct because it configures the preload.keys correctly for Redis L2 caching on an Adobe Commerce on-premise instance. Redis L2 caching is a feature that allows storing the cache data in both Redis and the local file system. This way, the cache data can be loaded faster from the local storage, while Redis acts as a cache invalidation service. To use Redis L2 caching, the backend option for both frontend => page_cache and frontend => default must be set to Magento\Framework\Cache\Backend\RemoteSynchronizedCache1. To enable the preload feature, which reduces the number of requests to Redis, the preload.keys option must be specified with the cache keys that are loaded on each frontend request. However, unlike Redis L1 caching, the preload.keys must include the suffix :hash to indicate that only the hash values of the cache data are stored in Redis2.
Therefore, the correct configuration for preload.keys is:
<preload_keys' => [ '762_EAV_ENTITY_TYPES:hash', '762_GLOBAL_PLUGIN_LIST:hash',
'762_DB_IS_UP_TO_DATE:hash', '762_SYSTEM_DEFAULT:hash', ],
Option A is incorrect because it configures the preload.keys incorrectly for Redis L2 caching. It uses the id_prefix of frontend => page_cache (063_) instead of frontend => default (762_) for the cache keys.
This will cause a mismatch between the cache keys and the cache data, and result in incorrect or missing cache data. Moreover, it does not include the suffix :hash for the preload.keys, which is required for Redis L2 caching2.
Option B is incorrect because it configures the preload.keys incorrectly for Redis L2 caching. It does not include the suffix :hash for the preload.keys, which is required for Redis L2 caching2. It also uses a wrong cache key (GLOBAL_PLUGIN_LIST) instead of GLOBAL_PLUGIN_LIST.
Option D is incorrect because it configures the preload.keys incorrectly for Redis L2 caching. It uses a wrong id_prefix (162_) instead of frontend => default (762_) for the cache keys. This will cause a mismatch between the cache keys and the cache data, and result in incorrect or missing cache data. It also uses a wrong cache key (EAV_ENTITY_TYPES) instead of EAV_ENTITY_TYPES.

NEW QUESTION # 36
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.)
- A. Multithreaded checkout processing admin panel setting (stores > settings > configuration > sales > checkout > General settings > Asynchronous) can be set to a higher value representing the number of PHP threads used exclusively for checkout
- B. A new database can be created and the Split Database feature can be automatically configured with the following command: bin/Magento setup:db-schema:spiit-sales -host"<checkout db host or ip>-
--dbnanie""<name>" --username"<checkout db username)" --password""<password>" - C. Asynchronous email notifications admin panel setting (stores > settings > configuration > sales > sales Emails > General settings > Asynchronous) can be enabled
- D. The website deploy mode can be set to siege by executingthe following CLI command: bin/Magento deploy:mode:set siege, provided that it will be changed back to production as soon as the number of simultaneously placed orders decreases to acceptable levels
- E. Asynchronous indexing admin panel Setting (Stores > Settings > Configuration > Advanced> Developer
> Grid Settings > Asynchronous indexing) can be enabled by executing the following CLI Command:
bin/Magento config:set dev/grid/async_indexing 1
Answer: B,E
Explanation:
Explanation
Option A is correct because enabling asynchronous indexing can improve the checkout performance by reducing the database load and avoiding locking issues. Asynchronous indexing allows the indexers to run in the background without affecting the frontend operations. The command bin/magento config:set dev/grid/async_indexing 1 can be used to enable this option in the production mode1.
Option C is correct because creating a new database and splitting the sales tables can also improve the checkout performance by distributing the database load and avoiding contention. Splitting the database allows the checkout and order management operations to use a separate master database from the rest of the Magento application tables. The command bin/magento setup:db-schema:split-sales
--host="<checkout db host or ip>" --dbname="<name>" --username="<checkout db username>"
--password="<password>" can be used to configure this feature2.
Option B is incorrect because enabling asynchronous email notifications does not affect the checkout performance directly. Asynchronous email notifications allow the order confirmation emails to be sent in batches by a cron job instead of immediately after placing an order. This option can reduce the server load and improve the customer experience, but it does not impact the checkout process itself3.
Option D is incorrect because there is no such deploy mode as siege in Magento 2. The available deploy modes are default, developer, and production. Changing the deploy mode can affect the performance, caching, and error handling of the Magento application, but it does not directly affect the checkout performance4.
Option E is incorrect because there is no such admin panel setting as multithreaded checkout processing in Magento 2. The number of PHP threads used for checkout is determined by the web server configuration and the PHP-FPM settings, not by the Magento application settings. Increasing the number of PHP threads may improve thecheckout performance, but it also requires more server resources and may cause other issues5.

NEW QUESTION # 37
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?
- A. Developer Mode
- B. Default Mode
- C. Production Mode
Answer: A
Explanation:
Explanation
Developer mode is the best option for setting up a development environment for testing functionality, not performance, before being passed to the testing team. In developer mode:
Errors are logged and hidden from the user. This ensures that the user does not see any uncaught exceptions or debugging information, but the developers can still access them from the log files.
Cache mode can only be changed from command line. This prevents any accidental or unauthorized changes to the cache settings from the admin panel or other sources.
Static files are created dynamically and then cached. This allows the developers to see the latest changes to the static files without having to run the static content deployment command every time. The static files are also cached for faster loading.

NEW QUESTION # 38
An Adobe Commerce Architect is reviewing API-functional test code. Some tests send errors to indicate that the customer address does not exist. The test codes show the following:
Which step should the Architect take to fix the test errors?
- A. Change the annotation to Use@magentoApiDataFixture Magento/Customer/_files/ instead Or dmagentoDataFixture Magento/Customer/_files/customer_one_address.php
- B. Set the annotation to USe AmagentoPersistDataFixture Magento/Cu5tomer/_f iles/custcwer_one_address.php instead Of @magentoDataFixture Magento/Customer/_f iles/customer_one_address.php
- C. Update the annotation to Specify addreSSjd EniagentoDataFixture Magento/Customer/_files/customer_one_address.php with:{Maddress_id":"$address.id$"}
Answer: B
Explanation:
Explanation
The issue is being caused by the use of @magentoDataFixture annotation, which creates a temporary data fixture that is rolled back after each test execution1. This means that the customer address created by the fixture is not persisted in the database and cannot be retrieved by subsequent tests. To fix this, the Architect should use @magentoPersistDataFixture annotation, which creates a permanent data fixture that is not rolled back after each test execution2. This way, the customer address created by the fixture will be persisted in the database and can be accessed by subsequent tests. Changing the annotation to use @magentoApiDataFixture or specifying address_id in the annotation will not solve the issue, as they are not related to the persistence of the data fixture3.

NEW QUESTION # 40
An Adobe Commerce Architect is troubleshooting an issue on an Adobe Commerce Cloud project that is not yet live.
The developers copied the Staging Database to Production in readiness to Go Live. However, when the developers test their Product Import feature, the new products do not appear on the front end.
The developers suspect the Varnish Cache is not being cleared. Staging seems to work as expected. Production was working before the database migration.
What is the likely cause?
- A. A deployment should have been done on Production to initialize Fatly caching.
- B. The site URLs in the Production Database are the URLs of the Staging Instance and must be updated
- C. Thefatlycredentials in the Production Database are incorrect.
Answer: B
NEW QUESTION # 41
An Adobe Commerce Architect is supporting deployment and building tools for on-premises Adobe Commerce projects. The tool is executing build scripts on a centralized server and using an SSH connection to deploy to project servers.
A client reports that users cannot work with Admin Panel because the site breaks every time they change interface locale.
Considering maintainability, which solution should the Architect implement?
- A. Modify project config.php file, configure 'admin_locales_for_deploy' value, and specify all required locales
- B. Edit project env.php file, configure 'adminJocales_for_build' value, and specify all required locales
- C. Adjust the tools build script and specify required locales during *setup:static-content:deploy' command
Answer: C
Explanation:
Explanation
The issue here is that the site breaks every time the users change interface locale in the Admin Panel. This is because the static content for the different locales is not generated during the deployment process. The solution is to adjust the tools build script and specify required locales during *setup:static-content:deploy' command. This will ensure that the static content for all the needed locales is generated and deployed to the project servers. References:
