Question 1/15
😊 Your answer was correct 🙁 Your answer was incorrect
In Laravel, how do you register resourceful routes to a 'PostController'?

Available answers

To register resourceful routes in Laravel, use the Route::resource method: 
Route::resource('posts', 'PostController');
This automatically handles RESTful actions for the controller like index, create, store, show, etc.
Question 2/15
😊 Your answer was correct 🙁 Your answer was incorrect
When you use the '?<parameter>' syntax in a route parameter, what is implied about that parameter in Laravel?

Available answers

The '?' syntax in a route parameter indicates that the parameter is optional in Laravel. For example, Route::get('/user/{id?}', 'UserController@show'); would mean 'id' is optional when calling this route, so it can be omitted.
Question 3/15
😊 Your answer was correct 🙁 Your answer was incorrect
How can you restrict a route to only accept POST requests?

Available answers

To restrict a route to only accept POST requests, use the Route::post method: 
Route::post('/submit', 'SubmitController@store');
This ensures that the route will only respond to HTTP POST requests.
Question 4/15
😊 Your answer was correct 🙁 Your answer was incorrect
In Laravel, where do you typically define your routes for web (HTTP) requests?

Available answers

Routes for web (HTTP) requests in Laravel are defined in the routes/web.php file. This file is included in the application by default to handle all browser-based requests.
Question 5/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the syntax to pass a parameter dynamically from a route to a controller in Laravel?

Available answers

To dynamically pass a parameter from a route to a controller, define it in the URL pattern: 
Route::get('/posts/{post}', 'PostController@show');
This route structure allows the function in PostController to automatically receive the '{post}' parameter.
Question 6/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which URI pattern would you use for defining a route that should match any subdomain in a Laravel application?

Available answers

To match routes for any subdomain in Laravel, use the pattern {subdomain}.example.com. This makes the subdomain part dynamic and routable. For example: 
Route::domain('{subdomain}.example.com')->group(function () { ... });
This will handle requests for any subdomain of example.com.
Question 7/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is a Closure in the context of Laravel routing?

Available answers

In the context of Laravel routing, a Closure is an anonymous function defined directly within a route definition. For example: 
Route::get('/example', function () { return 'Hello World'; });
This closure returns a response directly without a controller.
Question 8/15
😊 Your answer was correct 🙁 Your answer was incorrect
In Laravel, how can you handle multiple HTTP verbs for the same route URI in a controller?

Available answers

In Laravel, you can handle multiple HTTP verbs for the same route URI by using Route::match() or Route::any(). For example: 
Route::match(['get', 'post'], '/submit', 'SubmitController@handle');
or 
Route::any('/submit', 'SubmitController@handle');
The difference is that Route::any() will match all verbs.
Question 9/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which helper function can be used to generate URLs for named routes in Laravel?

Available answers

The route() helper function in Laravel is used to generate URLs for named routes: 
return route('profile');
This is convenient for generating URLs for endpoints with dynamic checks.
Question 10/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which routing method would be suitable for an API that handles both GET and POST requests at the same endpoint in Laravel?

Available answers

The Route::match(['get', 'post'], '/api/data', 'ApiController@handleData'); method allows handling of both GET and POST requests at the same endpoint in Laravel. This ensures that the route will respond to either HTTP verb.
Question 11/15
😊 Your answer was correct 🙁 Your answer was incorrect
How can you pass multiple middleware to a single route in Laravel?

Available answers

In Laravel, you can pass multiple middleware to a route by enclosing them in an array: 
Route::get('/dashboard', 'DashboardController@index')->middleware(['auth', 'verified']);
This way, both 'auth' and 'verified' middleware will be applied to the route.
Question 12/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which code snippet correctly groups routes inside middleware with the name 'auth'?

Available answers

In Laravel, to apply middleware to a group of routes, use: 
Route::middleware('auth')->group(function () { ... });
This will ensure that the 'auth' middleware is applied to all routes within the group.
Question 13/15
😊 Your answer was correct 🙁 Your answer was incorrect
How can you apply a middleware to a single route in Laravel?

Available answers

In Laravel, you can apply a middleware to a single route using the middleware method: 
Route::get('/dashboard', 'DashboardController@index')->middleware('auth');
Alternatively, you can also place the middleware method before defining the route: 
Route::middleware('auth')->get('/dashboard', 'DashboardController@index');
Both are correct ways to apply middleware.
Question 14/15
😊 Your answer was correct 🙁 Your answer was incorrect
In which file would you typically protect routes by implementing policies in Laravel?

Available answers

In Laravel, policies are registered in the App\Providers\AuthServiceProvider.php file. This is where you map your policies to the corresponding models, allowing you to protect routes using defined policies.
Question 15/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the default scope of a route parameter in Laravel?

Available answers

In Laravel, route parameters have an implicit scope based on their order of declaration in the URL. For example, /user/{id}/post/{postId} will expect 'id' and 'postId' in that order.
