LARAVEL Professional Standards & Competencies 5

Question 1

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

Accepted Answer

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

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

php artisan migrate:status

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

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

Answer

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