After antivirus filtering, which outcomes may occur?

• A. Drop the object
• B. Send the object to the firewall to pass to the destination
• C. Pass the object to the destination directly
• D. All of the above

Answer: (D)

Antivirus filtering acts as the gatekeeper for content crossing the network, deciding what to do based on what it finds and the security policy in place. If malware is detected, the item is typically dropped or quarantined to prevent delivery. If the content is clean, it can be allowed to reach the destination. In some setups, the traffic may be redirected to the firewall for final handoff to the destination, rather than passing directly. Because deployments and policies vary, all of these outcomes are possible: the content can be dropped, passed through, or routed via the firewall for delivery.
