Question No. 1

A message queue currently has queue/consumer-wait-for-messages set to true, which allows the consumer process to run until a message is inserted into the queue. A piece of functionality is driven by data stored in the model

\Magento\variable\Model\variable and this value is only loaded once during the consumer run. If the variable is updated we want the consumer to restart so that the new value is loaded into memory without having to reload the variable on each message consumed.

The Adobe Commerce developer has created an after plugin on the \Magento\Variable\Model\variable:: save() function.

How would the developer use the plugin to trigger the consumer restart?

ACall the function \Magento\Framework\MessageQueue\PoisonPill\Poi5onPillPutInterface::put().

BCall the function \Magento\Framework\MessageQueue\Consumers\TriggerRe5tartInterface:trigger().

CSet the global Cache key trigger_consumer_restart t0 1.

Show Answer

Correct Answer: B

The developer can use the plugin to trigger the consumer restart by calling the function \Magento\Framework\MessageQueue\Consumers\TriggerRe5tartInterface:trigger(). This function will write a flag to the cache storage that will be checked by the consumer process.If the flag is set, the consumer process will terminate itself and restart with the updated configuration.

Question No. 3

An Adobe Commerce developer added a new API method to search and retrieve a list of Posts for a custom Blog functionality. This is the content of the module's etc/webapi.xml file:

The new code has been deployed to production and the merchant is using https: //merchant. domain. com/swagger to review the new endpoint, but it is not visible in swagger.

What would be a reason for this?

AThe webapi.xml file should be moved into the etc/webapi_rest/webapi.xml file.

BSince the new endpoint is not anonymous, the merchant needs to enter a valid integration token in swagger in order to see the new method.

CThe greturn annotation is missing in the MyVendor\Blog\Api\PostRepositoryInterf ace class.

Show Answer

Correct Answer: B

The reason why the new endpoint is not visible in swagger is that since the new endpoint is not anonymous, the merchant needs to enter a valid integration token in swagger in order to see the new method. The webapi.xml file specifies that the resource for the new endpoint is MyVendor_Blog::post, which means that only authorized users with this permission can access it. To generate an integration token, the merchant needs to create an integration in the admin panel and activate it. Then they can copy the token and paste it in swagger's authorization field.

Question No. 4

An Adobe Commerce developer is tasked with creating a custom block that will be displayed on every page in the footer of the site.

After completing and optimizing the development, the developer notices that the block takes too much time to be generated on each page and decides to store it in the system cache after enabling it for all cache groups.

What would be the minimum requirement to achieve this?

ASet a value for the cache_Lifetime data property of the block.

BSet a value for cache_key data property of the block.

CSet values for both cache_lifetime and cache_key data properties of the block.

Show Answer

Correct Answer: C

To store a block in the system cache, the developer needs to set values for both the cache_lifetime and cache_key data properties of the block. The cache_lifetime property specifies how long the block should be cached, and the cache_key property specifies a unique identifier for the block.

The following code shows how to set the cache_lifetime and cache_key data properties of a block:

PHP

$block->setData('cache_lifetime', 600);

$block->setData('cache_key', 'my_custom_block');

Once the cache_lifetime and cache_key data properties have been set, the block will be stored in the system cache and will not be regenerated on each page load.

Question No. 5

An international merchant is complaining that changes are taking too long to be reflected on the frontend after a full product import.

Thinking it may be database issues, the Adobe Commerce developer collects the following entity counts:

* Categories: 900

* Products: 300k

* Customers: 700k

* Customer groups : 106

* Orders: 1600k

* Invoices: 500k

* Creditmemos: 50k

* Websites : 15

* Stores : 45

What is a probable cause for this?

AThe combination of the number of products, categories and stores is too big. This leads to a huge amount of values being stored in the flat catalog indexes which are too large to be processed at a normal speed.

BThe combination of the number of orders, customers, invoices and creditmemos is too big. This leads to a huge amount of values being stored in the customer grid index which is too large to be processed at a normal speed.

CThe combination of the number of products, customer groups and websites is too big. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed.

Show Answer

Correct Answer: C

The probable cause for the delay in reflecting the changes on the frontend after a full product import is the combination of the number of products, customer groups and websites. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed. The price index calculates the final price of each product for each customer group and website, taking into account various factors such as tax, discounts, catalog price rules, etc. When there are many products, customer groups and websites, the price index becomes very complex and time-consuming to update.
