An Adobe Commerce developer has added a new configuration field to the admin area. The path for this option is general/store_information/out_of_hours_phone. Keeping simplicity in mind, how would the developer ensure this option contains a valid US telephone number?
A. Add phoneUS to the field in system.xml.
B. Create a backend model to check the validity of the phone number entered.
C. Add to the field in system.xml.
Explanation: According to the Magento Stack Exchange answer, system.xml is a file that defines the configuration fields for the admin area. Each field can have a validate attribute that specifies a validation rule for the field value. Magento provides some built-in validation rules, such as phoneUS, which validates a US telephone number. Therefore, to ensure that the option contains a valid US telephone number, the developer needs to add phoneUS to the field in system.xml.
How would a developer enable the magnification of CSS files on an Adobe Commerce Cloud Staging environment?
A. Locally from the command line
bin/magento config:set --lock-config dev/css/minify_files 1
Commit the app/etc/config.php file and redeploy.
B. Update the stores > setting > configuration > Advanced > Developer > css configuration in the Admin Panel.
C. SSH to the Adobe Commerce Staging environment. From the command line
ece-tools config: set dev/css/minify_files ps
bin/magento setup: static-content: deploy
Explanation: The developer can enable the magnification of CSS files on an Adobe Commerce Cloud Staging environment by locally running the command bin/magento config:set --lock-config dev/css/minify_files 1 from the command line. This will set the configuration value in the app/etc/config.php file and lock it from being changed in the Admin Panel. The developer then needs to commit the app/etc/config.php file and redeploy the environment.
Which hashing algorithm will Adobe Commerce choose to hash customer passwords?
A. If the Sodium extension is installed, SHA256 will be chosen, otherwise MD5 will be used as the Magento default hashing algorithm.
B. If the Sodium extension is installed, Argon 2ID13 will be chosen, otherwise SHA256 will be used as the Magento default hashing algorithm.
C. It does not matter if the Sodium extension is installed or not, the Magento hashing default algorithm will be SHA256.
Explanation:
If the Sodium extension is installed, Argon 2ID13 will be chosen as the Magento default hashing algorithm. Otherwise, SHA256 will be used.
The Sodium extension is a PHP extension that provides cryptographic functions. Argon 2ID13 is a password hashing algorithm that is considered to be more secure than SHA256.
If the Sodium extension is installed, Magento will use Argon 2ID13 as the default hashing algorithm for customer passwords. If the Sodium extension is not installed, Magento will use SHA256 as the default hashing algorithm.
An Adobe Commerce developer is being tasked with creating a new cron job to run a method that has already been written. What are the minimally required steps to accomplish this?
A. Create a crontab.xmi file and a new system configuration in system.xmi for the schedule.
B. Create crontab.xmi and cron_groups.xmi files to assign the new job to a cron group.
C. Create a crontab.xmi file and set a schedule for the new cron job.
Explanation: According to the Configure and run cron guide for Magento 2 developers, the crontab.xmi file is used to declare and configure cron jobs for a module. The file should specify the name, instance, method and schedule of the cron job. Therefore, creating a crontab.xmi file and setting a schedule for the new cron job are the minimally required steps to accomplish this task.
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?
A. Set a value for the cache_Lifetime data property of the block.
B. Set a value for cache_key data property of the block.
C. Set values for both cache_lifetime and cache_key data properties of the block.
Explanation:
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.
