A technician wants to update the contents of the /etc/hosts.allow file. The technician reviews the following output: According to best practice, which of the following commands should the technician u

Using setfacl to assign a targeted write ACL entry for the specific user follows the principle of least privilege - the user receives only write access to that one file without gaining broad sudo rights or becoming the file owner. This keeps the base permissions and ownership of /etc/hosts.allow intact while allowing the required edit, which is the recommended approach when fine-grained access control is available.

visudo is a safe editor exclusively for the /etc/sudoers file; it cannot be used to edit /etc/hosts.allow and will not open it correctly.

chgrp changes the file's group ownership, which permanently alters the file's permission model rather than granting a temporary, targeted ACL entry.

sudo vi grants full root-level access during the edit session, which is broader than necessary when ACL-based targeted write permission is available.

chown transfers ownership of a system-critical file to a regular user, which permanently weakens the file's security posture beyond what the task requires.
