Question 1

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?



Answer : B

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.

Question 2

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?



Answer : C

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.Reference:CBO coupling between object,Coupling Between Object classes (CBO),Cohesion and coupling of an object in OO programming


Question 3

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?



Answer : B

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.


Question 4

An Adobe Commerce Architect needs to scope a bespoke news section for a merchants Adobe Commerce storefront. The merchant's SEO agency requests that the following URL structure:

news/{date}/{article_url_key}, where {date} is the publication date of the article, and {article_url_key} is the URL key of the article.

The Architect scopes that a news entity type will be created. The date and URL key data will be stored against each record and autogenerated on save. The values will be able to be manually overridden.



Answer : B, C

These two options are both valid ways to manage routing for the bespoke news section and adhere to best practice. Option B leverages the existing URL rewrite functionality of Adobe Commerce, which allows creating custom URLs for any entity type and storing them in the database. This option requires creating a standard controller route for the news entity type, such as news/article/view/id/i, where i is the news article ID. Then, on saving each news article, a rewrite rule is generated that maps the internal URL to the desired SEO-friendly URL, such as news/{date}/{article_url_key}. The rewrite rule is stored in the url_rewrite table, which is used by the standard router to match and redirect requests.

Option C involves creating a custom router class that implements \Magento\Framework\App\RouterInterface and runs before the standard router in the routing process. The custom router class can match the news portion of the URL and extract the date and URL key parts from it. Then, it can look for and load a news article that matches those values using a model or repository class. If a match is found, it can set the request parameters accordingly and dispatch the request to a controller action that renders the news article page.

Question 5

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?



Answer : C

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.

Question 6

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?



Answer : A

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.Reference:

Question 7

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?



Answer : B

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