Why each option

FortiGate units can perform antivirus scanning on application-layer protocols that transport files and email content, such as POP3, FTP, and SMTP.

APOP3Correct

FortiGate units can inspect and scan POP3 traffic to detect and prevent viruses in email attachments and content retrieved by users.

BFTPCorrect

FortiGate units are capable of scanning FTP traffic for viruses as files are uploaded or downloaded, preventing the spread of malware through file transfers.

CSMTPCorrect

FortiGate units can scan SMTP traffic to identify and block emails containing viruses or malicious attachments before they reach recipients.

DSNMP

SNMP (Simple Network Management Protocol) is a network management protocol and is not designed to carry user data or files that would typically be scanned for viruses.

ENetBios

NetBIOS is a legacy networking API used for name resolution and session services, not an application-layer protocol for transferring files or content that would be subjected to antivirus scanning.
