A student's attempt to access a teacher's network folder is denied. Which of the following best explains the reason access is denied?

Location tracking pertains to monitoring a device's physical location, not to controlling access to network resources based on user permissions.

A firewall certificate is used for securing communication (e.g., VPNs, HTTPS) or identifying devices, not for granular user-level access control to network folders.

Multifactor authentication (MFA) verifies a user's identity more strongly, but if the authenticated user still lacks the necessary permissions, MFA alone won't grant access to a restricted resource.

The least privilege model ensures that users are granted only the minimum necessary permissions to perform their job responsibilities; a student typically does not have a legitimate need to access a teacher's private network folder, so access is correctly denied. This security principle prevents unauthorized access and reduces the potential impact of compromised accounts.
