Which significant risk is introduced by running the file transfer protocol (FTP) service on a server in a demilitarized zone (DMZ)?

A. A user from within could send a file to an unauthorized person.
B. FTP services could allow a user to download files from unauthorized sources.
C. A hacker may be able to use the FTP service to bypass the firewall.
D. FTP could significantly reduce the performance of a DMZ server.

Correct Answer: C

Explanation:

Explanation:
Since file transfer protocol (FTP) is considered an insecure protocol, it should not be installed on a server in a demilitarized zone (DMZ). FTP could allow an unauthorized user to gain access to the network. Sending files to an unauthorized person and the risk of downloading unauthorized files are not as significant as having a firewall breach. The presence of the utility does not reduce the performance of a DMZ server; therefore, performance degradation is not a threat.
