The correct answers are A and C.

The errors in the snippet are:

Column roll_no does not have an index. It is needed since attribute_identity is set to true.

Column student_name does not have an attribute length.

The attribute_identity attribute specifies whether the primary key of the table should be auto-incremented. If attribute_identity is set to true, then the roll_no column must have an index. The student_name column does not have an attribute length, which is required for string columns.

The following code shows how to fix the errors:

The developer can fix this issue by increasing the disk space of the database service. The database service is one of the services that run on the Adobe Commerce Cloud platform and provide functionality for the application. The database service uses MySQL as the database engine and stores data for products, customers, orders, etc. The disk space of the database service determines how much data can be stored and processed by the database. If the disk space is insufficient, the database import can fail with a disk space error. The developer can increase the disk space of the database service by modifying the .magento/services.yaml file and redeploying the environment. Verified References: [Magento 2.4 DevDocs]

The following SearchCriteria query will replicate the SQL query:

$searchCriteria = new \Magento\Framework\Api\SearchCriteriaBuilder();

$searchCriteria->addFilter('name', 'Brand 1', 'eq');

$searchCriteria->addFilter('status', 1, 'eq');

$brandCollection = $this->brandRepository->getList($searchCriteria);

Two options to get the connection credentials for the environment’s deployed services are to run the magento-cloud relationships CLI command and to connect to the server via SSH and read $_ENV[‘services’] variable. The magento-cloud relationships CLI command displays information about the relationships between an environment and its services, such as database, cache, search, etc. The developer can use this command to get the connection data for each service in JSON format. Alternatively, the developer can connect to the server via SSH and read the $_ENV[‘services’] variable, which contains the same information as the CLI command output.
