A security audit concludes that an organization's database servers need to be hardened. As a result, an administrator obtans tie fofcjwwng partial Nmap output from a database server. Which of the foll

Option A likely installs or enables an additional service, which increases rather than reduces the attack surface identified in the Nmap output.

Option B likely only stops a service temporarily without disabling it, meaning it would reactivate on reboot and leave the vulnerability unmitigated long-term.

Option C likely modifies a file permission or ownership setting that does not address the open network port identified as the security risk by Nmap.

Option D (not visible as text in this rendering) most likely uses 'systemctl stop' and 'systemctl disable' to shut down and prevent restart of a non-database service revealed as open by the Nmap output. Disabling unnecessary listening services reduces the server's attack surface in line with the principle of least exposure.
