What happens when you access a file stored on the public disk without creating a symbolic link?

In Laravel, the public disk stores files in storage/app/public. To make these files accessible via the web, a symbolic link is usually created from public/storage to storage/app/public.

What will happen if you try to access a file stored on the public disk via a URL without creating this symbolic link?

AThe web server will return a 404 Not Found error because the file is not reachable.
BThe file will be accessible via the URL as expected.
CLaravel will automatically create the symbolic link on the first request.
DThe file will be downloaded instead of displayed in the browser.

Why does this Laravel code fail to access a public disk file after deployment?

After deploying a Laravel app, the following code tries to get the URL of a file stored on the public disk:

Storage::disk('public')->url('example.jpg');

But the URL returns a 404 error. What is the most likely cause?

AThe file <code>example.jpg</code> does not exist in <code>storage/app/public</code>.
BThe symbolic link from <code>public/storage</code> to <code>storage/app/public</code> was not created on the server.
CThe <code>public</code> disk is not configured in <code>config/filesystems.php</code>.
DThe web server does not have permission to read the <code>storage/app/public</code> directory.

What is the purpose of the symbolic link in Laravel's public disk setup?

Laravel uses a symbolic link from public/storage to storage/app/public. Why is this symbolic link necessary?

ATo allow files stored in <code>storage/app/public</code> to be accessible via the web through the <code>public</code> directory.
BTo move files from <code>storage/app/public</code> to <code>public/storage</code> automatically.
CTo prevent users from accessing files in <code>storage/app/public</code> directly.
DTo back up files stored in <code>storage/app/public</code> to the <code>public</code> directory.

What is the output of this Laravel code snippet regarding symbolic link existence?

Consider this Laravel code snippet executed in a controller method:

if (is_link(public_path('storage'))) {
    echo 'Link exists';
} else {
    echo 'Link missing';
}

Assuming the symbolic link was created correctly, what will be the output?

Laravel
if (is_link(public_path('storage'))) {
    echo 'Link exists';
} else {
    echo 'Link missing';
}
ARuntime error because public_path() is undefined
BLink missing
CLink exists
DSyntax error due to missing semicolon

💡 Hint

Recall what is_link() checks and what public_path() returns in Laravel.
