Which of the following statements is correct regarding the antivirus scanning function on the FortiGate unit?

Antivirus scanning on a FortiGate provides protection at the network perimeter, not 'end-to-end' for client workstations, which still require their own endpoint security solutions.

While FortiGate AV scans many common protocols, the core antivirus function protects a wider range of application layer protocols than just HTTP, Telnet, SMTP, and FTP, and Telnet is less relevant for virus protection in modern contexts.

Banned word checking is a feature typically associated with data loss prevention (DLP) or content filtering, not primarily with the core antivirus scanning function.

FortiGate's antivirus scanning capabilities extend beyond traditional viruses to include protection against grayware. Grayware refers to applications that are not necessarily malicious but can still cause undesirable behavior, such as adware, spyware, and other potentially unwanted applications (PUAs).
