Professional Standards & Competencies Flashcards

What is the professional Laravel standard for handling jobs that fail after all retry attempts are exhausted?

Answer: Log to the `failed_jobs` table and implement the `failed()` method on the job class

Laravel stores failed jobs in the `failed_jobs` table and calls the job's `failed()` method, allowing developers to handle cleanup or notifications.

Which Laravel practice is essential for preventing mass assignment vulnerabilities in Eloquent models?

Answer: Defining `$fillable` to whitelist assignable attributes or using `$guarded` to blacklist

Defining `$fillable` (whitelist) or `$guarded` (blacklist) on Eloquent models prevents mass assignment of unintended attributes from user input.

In a professional Laravel project using CI/CD, which command validates that migrations are in sync before deploying?

Answer: php artisan migrate:status

`php artisan migrate:status` lists all migrations and whether they have been run, helping identify pending migrations before a production deploy.

What is the professional approach to caching frequently-read, rarely-changed data in Laravel?

Answer: Use `Cache::remember()` with an appropriate TTL and cache driver

`Cache::remember()` retrieves cached data if available, or executes the closure and stores the result for the given TTL, minimizing redundant database calls.

Which professional practice applies when scheduling recurring tasks in a Laravel application?

Answer: Define all scheduled tasks in `app/Console/Kernel.php` using the `schedule()` method and use a single cron entry

Laravel's task scheduler centralizes all recurring commands in `Kernel.php` with fluent frequency methods, requiring only one `* * * * * php artisan schedule:run` cron entry.

What is the correct professional approach for seeding a production database in Laravel?

Answer: Create separate production seeders and run them with `--class` flag after careful review

Production seeders should contain only required reference data, run explicitly with `php artisan db:seed --class=ProductionSeeder` after review to avoid inserting test data.

Which Laravel feature enforces consistent coding standards across a development team?

Answer: Laravel Pint (PHP CS Fixer wrapper)

Laravel Pint is an opinionated PHP code style fixer built on PHP-CS-Fixer that enforces consistent code formatting aligned with Laravel conventions.
