NEW QUESTION # 31
A merchant is using a unified website that supports native Adobe Commerce B2B and B2C with a single store view.
The merchant's objective is to display the B2B account features, such as negotiable quotes and credit limits, in the header of the site on every page for logged-in users who belong to a B2B company account.
Each B2B company possesses its unique shared catalog and customer group, while numerous customer groups for non-B2B customers undergo changes. The merchant insists that this association should not be linked to customer groups.
Which two solutions should the Architect recommend for consideration, taking into account public data and caching? (Choose two.)

A. Create a new custom condition for customer segments that allow for choosing whether a user is part of a B2B company and then use this segment to modify the output accordingly.
B. Create a Virtual Type that switches the theme when a user is part of a B2B company so the output can be modified accordingly in the alternate theme.
C. Create a new HTTP Context variable to allow for separate public content to be cached for users in B2B companies where the output can be modified accordingly.
D. Set whether the current user is part of a B2B company in the customer session and use that data directly to modify the output accordingly.
E. Check if the current user is part of a B2B company within a block class and modify the output accordingly.

Answer: A,C

Explanation:
Explanation
Option B is a valid solution because creating a new HTTP Context variable can allow for differentiating the public content cache for users who belong to a B2B company account. The HTTP Context variable can be used to modify the output of the header block accordingly, without affecting the performance or scalability of the site1 Option D is also a valid solution because creating a new custom condition for customer segments can enable targeting users who are part of a B2B company account. The customer segment can be used to modify the output of the header block accordingly, using layout updates or dynamic blocks. This solution can also leverage the existing customer segment functionality and avoid custom coding2 Option A is not a valid solution because switching the theme based on a virtual type can cause performance issues and increase the complexity of the site maintenance. Moreover, switching the theme can affect the entire site appearance, not just the header block3 Option C is not a valid solution because using the customer session data directly to modify the output of the header block can prevent the public content cache from working properly. The customer session data is private and cannot be cached, so this solution can negatively impact the performance and scalability of the site4 Option E is not a valid solution because checking if the current user is part of a B2B company within a block class can also prevent the public content cache from working properly. The block class logic is executed on every request, so this solution can negatively impact the performance and scalability of the site5 References:

NEW QUESTION # 32
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 GraphQI 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?

A. Create a new ClaSS inheriting from
Magento\GraphQlCache\Model\CacheId\CacheIdFactorProvidftrInterface and returning the Value of my_attribute from the getFactorValuefunction and my_attribute from the getFactorName function. Then add this class through Dl to the idFactorProviders array ofMagento\GraphQlCache\Model\CacheId\CacheIdCalculator.
B. Createa new class inheriting from Magento\Framework\GraphQi\Query\Resolver\identityinterfaca and returning the value of my_attributefrom the getidentities function.
Then specify a ecache(cacheidentity: Path\\To\\identityclass) directive for each GraphQL query to include the newly created IdentityClass to each query that adds the cache tags for each customer.
C. Create a new class inheriting from Magento\customer\customerData\stctionSourceinterface and returning the value of my_attributefrom the getSectionData function. Then add thisClaSS through the sectionSourceMap array Of Magento\Customer\CustomerData\SectionPoolInterface.

Answer: A

Explanation:
Explanation
To make sure the vcl_hash function of Varnish considers the newly created attribute, the Architect needs to do the following steps:
Create a new class that implements the
Magento\GraphQlCache\Model\CacheId\CacheIdFactorProviderInterface interface. This interface defines two methods: getFactorName and getFactorValue. The getFactorName method should return the name of the attribute, in this case, my_attribute. The getFactorValue method should return the value of the attribute for the current customer, which can be obtained from the customer session or customer repository1.
Add this class to the idFactorProviders array of
Magento\GraphQlCache\Model\CacheId\CacheIdCalculator through dependency injection. The CacheIdCalculator is responsible for generating a cache ID for each GraphQL request based on the factors provided by the idFactorProviders. By adding the new class to this array, the Architect ensures that the cache ID will include the value of my_attribute1.
The cache ID is then used by Varnish to hash and lookup the cached response for each request. By including my_attribute in the cache ID, the Architect ensures that Varnish will serve different responses based on the attribute value of the customer2.

NEW QUESTION # 33
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. Magento framework uses INSERT on DUPLICATE, which leads to reaching the max limit of the increment of the column.
B. EAV attribute import uses REPLACE, which leads to reaching the max limit of the increment of the column
C. Integrity constraints were dropped after upgrading to the latest version, and the integrity checks were missed.

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 # 34
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. Create Customer_ProductType: :Test/_files/{fixture_name)_rollback.php for every fixture
B. Modify method PHPDoc and change annotation @magentoDbIsolation to enabled
C. Add annotation @magentoApplsolation enabled to method PHPDoc

Answer: B

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:
https://developer.adobe.com/commerce/testing/guide/integration/#database-isolation1

NEW QUESTION # 35
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?

A. Mark the controller by setting no-cache HTTP headers
B. Specify a new action in a sections.xml configuration file
C. Invalidate the status of gift registry indexers

Answer: B

Explanation:
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. References:

NEW QUESTION # 36
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 isimplemented 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?

A. Override getResponse, save the response to a variable, check if the response exists, then return.
B. ln_doShipmentRequest()f call canCollectRates() before sending request to the API.
C. Implement _setCachedQuotes() and _getCachedQuotes(), return the data if the request matches.

Answer: C

Explanation:
Explanation
The carrier model class can implement caching methods to store and retrieve the quotes from the API based on the request parameters. This can reduce the number of API calls and improve the performance of the shipping rate calculation. The _setCachedQuotes() method can save the response from the API to a cache storage, and the _getCachedQuotes() method can check if there is a cached response for the current request and return it if it exists. References: Caching in carrier model, Carrier model interface

NEW QUESTION # 37
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. Edit project env.php file, configure 'adminJocales_for_build' value, and specify all required locales
B. Modify project config.php file, configure 'admin_locales_for_deploy' 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:
https://experienceleague.adobe.com/docs/commerce-cloud-service/user-guide/develop/deploy/static-content.htm

NEW QUESTION # 38
A client is migrating to Adobe Commerce Cloud and has approximately 800 existing redirects that must be implemented. The number of redirects cannot be reduced because all redirects are specific, and do not match any pattern.
How should the redirects be configured to ensure performance?

A. Use VCL snippets to offload the redirect to Fastly.
B. Add each redirect as a URL rewrite via the admin Ul.
C. Add each redirect in the magento/routes.yaml file.

Answer: A

Explanation:
Explanation
Option B is correct because using VCL snippets to offload the redirect to Fastly is the best way to configure the redirects and ensure performance. VCL snippets are custom code segments that can be added to the Fastly configuration to modify the behavior of the caching service. By using VCL snippets, the redirects can be handled at the edge server level, without reaching the Magento application or the database. This reduces the server load and improves the response time for the redirected requests1.
Option A is incorrect because adding each redirect in the magento/routes.yaml file is not a recommended way to configure the redirects. The magento/routes.yaml file is used to define custom routes for Magento Cloud projects, such as mapping domains or subdomains to environments or services. Adding redirects in this file can cause conflicts with the existing routes and affect the routing logic of the project2.
Option C is incorrect because adding each redirect as a URL rewrite via the admin UI is not an optimal way to configure the redirects. The URL rewrite feature in Magento allows creating custom URLs for products, categories, and CMS pages, and redirecting them to their canonical URLs. However, adding a large number of URL rewrites can increase the database size and affect the performance of the Magento application. Moreover, using the admin UI for this task can be tedious and error-prone3.

NEW QUESTION # 39
An Architect wants to create an Integration Test that does the following:
* Adds a product using a data fixture
* Executes $this->someLogic->execute($product) on the product
* Checks if the result is true.
$this->someLogic has the correct object assigned in the setup() method.
Product creation and the tested logic must be executed in the context of two different store views with IDs of 3 and 4, which have been created and are available for the test.
How should the Architect meet these requirements?

A. Create one test class with one test method. Use the
\Magento\TestFramework\store\ExecuteinstoreContext class once in the fixture and another time in the test.
B. Create one test class with two test methods. Use the emagentostorecontext 3 annotation in one method and amagentostorecontext 4 in the other one.
C. Create two test classes with one test method each. Use the @magentoExecuteinstoreContext 3 and
$MagentoExecuteinStoreContext 4 annotations on the class level.

Answer: A

Explanation:
Explanation
To create an integration test that executes different logic in different store views, the Architect needs to do the following steps:
Create one test class that extends \Magento\TestFramework\TestCase\AbstractController or
\Magento\TestFramework\TestCase\AbstractBackendController, depending on the type of controller being tested1.
Create one test method that uses the @magentoDataFixture annotation to specify the data fixture file that creates the product2.
Use the \Magento\TestFramework\Store\ExecuteInStoreContext class to execute the fixture and the tested logic in different store views. This class has a method called executeInStoreContext, which takes two parameters: the store ID and a callable function. The callable function will be executed in the context of the given store ID, and then the original store ID will be restored3. For example:
PHPAI-generated code. Review and use carefully. More info on FAQ.
public function testSomeLogic()
{
// Get the product from the fixture
$product = $this->getProduct();
// Get the ExecuteInStoreContext instance from the object manager
$executeInStoreContext =
$this->_objectManager->get(\Magento\TestFramework\Store\ExecuteInStoreContext::class);
// Execute the fixture in store view 3
$executeInStoreContext->executeInStoreContext(3, function () use ($product) {
// Do some operations on the product in store view 3
});
// Execute the tested logic in store view 4
$result = $executeInStoreContext->executeInStoreContext(4, function () use ($product) {
// Call the tested logic on the product in store view 4
return $this->someLogic->execute($product);
});
// Assert that the result is true
$this->assertTrue($result);
}

NEW QUESTION # 40
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 steps are required when adding a product type with custom pricing? (Choose three.)

A. Data patch to register the new product type
B. Content of the etc/product_types.xml file
C. A new class with custom pricing logic, extending the abstract Product model class
D. New price model extending \Magento\Catalog\Model\Product\Type\Price
E. Hydrator for attributes belonging to the new product type
F. Custom type model extended from the abstract Product Type model

Answer: B,D,F

Explanation:
Explanation
To add a product type with custom pricing, the Architect needs to do the following steps:
Create a content of the etc/product_types.xml file that defines the new product type, its label, model, index priority, and price model. This file is used to register the new product type and its associated classes in Magento1.
Create a new price model that extends \Magento\Catalog\Model\Product\Type\Price and implements the custom pricing logic for the new product type. The price model is responsible for calculating the final price of the product based on various factors, such as special price, tier price, catalog price rules, etc2.
Create a custom type model that extends from the abstract Product Type model (\Magento\Catalog\Model\Product\Type\AbstractType) and overrides the methods related to the product type behavior, such as prepareForCart, getAssociatedProducts, etc. The type model defines how the product type interacts with other components, such as quote, order, cart, etc3.

NEW QUESTION # 41
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 Productlnterf ace 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 Productlnterface field my_attribute remains Int.
What prevented the value type of field my_attribute from changing?

A. The interface Productlnterface is already declared in Magento.CatalogGraphQI module. Extending requires use of the keyword extend before a new declaration of Productlnterface.
B. The fields of Productlnterface are checked during processing schema.graphqls files. If they have a corresponding attribute, then the backendjype of product attribute is set for field type.
C. The Magento_CatalogGraphQI module occurs later in sequence than the Magento_GraphQI module and merging output of dynamic attributes schema reader overrides types declared in schema.graphqls

Answer: A

Explanation:
Explanation
According to the Adobe Commerce documentation, to extend an existing GraphQL interface, the keyword extend must be used before the interface name. This indicates that the new declaration is adding or modifying fields to the existing interface, rather than redefining it. If the keyword extend is omitted, the new declaration will be ignored and the original interface will be used. In this case, the Architect wants to change the type of the my_attribute field in the ProductInterface interface, which is already declared in the Magento.CatalogGraphQl module. Therefore, the Architect should use the keyword extend before declaring the ProductInterface interface in the schema.graphqlsfile of the custom module. This will allow the Architect to override the type of the my_attribute field from Int to MyAttributeType.

NEW QUESTION # 42
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. GraphQL requests are always run against the default store view unless a store header or store cookie is provided.
C. The magento-vars.php file is not processed for any GraphQL requests, so the default website is always processed.

Answer: B

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 # 43
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:

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

A. Add a plugin after the getvalue method of $scopeConfig, remove the $encryptor from dependency and use it in the plugin to decrypt the value if the config name is user.secret'
B. Create a common config service class vendor\Pay-ient\Gateway\conf ig\conf ig under Vendor.Payment and use it as a parent class for all of the Vendor\PayimentModule\Gateway\Conf ig\Conf ig ClaSSeS and remove $scopeConf ig and Sencryptor dependencies
C. Replace all Vendor\PaymentModule\Gateway\Config\Config ClaSSeS With virtualType Of Magento\Payiaent\Gateway\Conf ig\Conf ig and Set <user_secret backend_Model="Magento\Config\Model\Config\Backend\Encrypted" /> Under config.xml

Answer: C

Explanation:
Explanation
The Architect should recommend replacing all Vendor\PaymentModule\Gateway\Config\Config Classes with virtualType of Magento\Payment\Gateway\Config\Config and setting <user_secret backend_Model="Magento\Config\Model\Config\Backend\Encrypted" /> under config.xml. This will avoid redundant dependency and duplicate code among the methods. The virtualType of Magento\Payment\Gateway\Config\Config will inherit the functionality of the base class and allow the customization of the constructor arguments, such as the pathPattern and valueHandlerPool. The backend_Model attribute of the user_secret field will specify that the value of this field should be encrypted and decrypted by the Magento\Config\Model\Config\Backend\Encrypted class, which implements the
\Magento\Framework\App\Config\ValueInterface interface and uses the
\Magento\Framework\Encryption\EncryptorInterfaceinternally12. This way, the payment modules do not need to depend on the \Magento\Framework\Encryption\EncryptorInterface or the
\Magento\Framework\App\Config\ScopeConfigInterface directly, and can use the getValue method of the Magento\Payment\Gateway\Config\Config class to get the decrypted value of the user_secret field3.

NEW QUESTION # 44
An Adobe Commerce store owner sets up a custom customer attribute "my.attribute".
An Architect needs to display additional content on the home page, which should display only to Customers with "my.attribute" of a certain value and be the same content for all of them. The website is running Full Page Cache.
With simplicity in mind, which two steps should the Architect take to implement these requirements? (Choose two.)

A. Create a Customer Segment and use 'my.attribute' in the conditions
B. Add a new context value of "my_attribute" to Magento\Framework\App\Http\Context
C. Add a dynamic block with the content to the Home Page
D. Add a custom block and a pHTML template with the content to the cmsjndexjndex.xml layout
E. Use customer-data JS library to retrieve "my.attribute" value

Answer: B,C

Explanation:
Explanation
To display additional content on the home page based on a custom customer attribute, the Architect needs to do the following steps:
Add a new context value of "my_attribute" to Magento\Framework\App\Http\Context. This will allow the Full Page Cache to generate different versions of the page for customers with different values of
"my.attribute". The context value can be set using a plugin on the Magento\Customer\Model\Context class.
Add a dynamic block with the content to the Home Page. A dynamic block is a type of content block that can be configured to display only to specific customer segments or conditions. The Architect can use the 'my.attribute' in the conditions of the dynamic block and assign it to the Home Page in the Content > Blocks section of the Admin Panel. References:

NEW QUESTION # 45
An Adobe Commerce Architect notices that the product price index takes too long to execute. The store is configured with multiple websites and dozens of customer groups.
Which two ways can the Architect shorten the full price index execution time? (Choose two.)

A. Move catalog_Price_index indexer to another custom indexer group
B. Edit customer groups to exclude websites that they are not using
C. Set mage_ihdexer_threads_COUNT environment variable to enable parallel mode
D. Enable price index customer group merging for products without tier prices
E. Set Customer Share Customer Accounts Option to Global

Answer: C,D

Explanation:
Explanation
The product price index can be optimized by using parallel mode and customer group merging. Parallel mode allows the indexer to run multiple threads simultaneously, which can speed up the indexing process. Customer group merging reduces the number of rows in the price index table by merging customer groups that have the same product prices. This can improve the performance of the price index queries and reduce the index size. References: Indexing optimization, Price index customer group merging

NEW QUESTION # 46
An Adobe Commerce Architect runs the PHP Mess Detector from the command-line interface using the coding standard provided with Adobe Commerce. The following output appears:

The Architect looks at the class and notices that the constructor has 15 parameters. Five of these parameters are scalars configuring the behavior of MyService. The class also contains three constants referencing one other class.
How should the Architect fix the code so that it complies with the coding standard rule?

A. Consolidate the constants referencing other classes into a string representation.
B. Introduce a new class accepting those five scalars and use it in the constructor and the remaining logic of MyService.
C. Modify the code of MyService so that the number of different classes and interfaces referenced anywhere inside the class is fewer than 13.

Answer: B

Explanation:
Explanation
The issue is being caused by the high coupling between objects (CBO) value of the class MyService. CBO is a metric that measures the number of classes that are coupled to a given class, either by method calls, property or parameter references, inheritance, or constants1. A high CBO value indicates that the class is too tightly coupled with other classes, which makes it more difficult to maintain, test, and reuse2. To reduce the CBO value, the Architect should introduce a new class that encapsulates the five scalar parameters that configure the behavior of MyService. This way, the constructor of MyService will only have one parameter of the new class type, instead of five scalar parameters. This will also make the code more readable and maintainable, as the new class can provide methods to access and manipulate the configuration data. The constants referencing other classes should not be consolidated into a string representation, as this would not reduce the CBO value and would make the code less clear and type-safe3. The number of different classes and interfaces referenced anywhere inside the class is not relevant for the CBO metric, as it only counts the classes that are coupled to the given class1.

NEW QUESTION # 47
An Architect is investigating a deployment issue with a server that is configured to work under the symlink directory /var/www/current, which lead to the latest released version of the application.
The deployment process performs the following steps:

After the last deployment, the merchant reported that the Adobe Commerce Import/Export functionality to export Customer Main File data is not working. The Architect discovered that the export file is not shown in the list of generated files.
Which change to the deployment process should be performed to solve this issue?

A. Doable Crontab before deployment and re-launch after deployment.
B. Restart the consumer process during deployment to use the directory with a new application version for export files.
C. Execute Command config:set export/customr/files_directory /var/releases/{release_nunber} toSet the new export path.

Answer: C

Explanation:
Explanation
The issue is that the export file is not shown in the list of generated files. This is because the export path is not set correctly. The solution is to execute the command config:set export/customr/files_directory
/var/releases/{release_nunber} to set the new export path. This will ensure that the export file is saved in the correct directory and can be accessed from the Admin Panel. References:

NEW QUESTION # 49
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?

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 # 50
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. 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
B. 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
C. 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>"
D. Asynchronous email notifications admin panel setting (stores > settings > configuration > sales > sales Emails > General settings > Asynchronous) can be enabled
E. 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

Answer: A,C

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.
