A new security engineer has started hardening systems. One of the hardening techniques the engineer is using
involves disabling remote logins to the NAS. Users are now reporting the inability to use SCP to transfer files to
the NAS, even though the data is still viewable from the users' PCs. Which of the following is the MOST likely
cause of this issue?


A. TFTP was disabled on the local hosts.
B. SSH was turned off instead of modifying the configuration file.
C. Remote login was disabled in the networkd.conf instead of using the sshd.conf.
D. Network services are no longer running on the NAS.
