Which option is an advantage to using network-based anti-virus versus host-based anti- virus?

Network-based antivirus operates at the network perimeter or inline on network segments, scanning traffic before it reaches endpoints. This architecture allows it to provide protection to any device on the network regardless of its OS or management status, including unmanaged IoT devices, legacy systems, and appliances that cannot support a traditional AV agent. Host-based AV cannot protect these devices because it requires a compatible agent installed on each endpoint.

Network-based antivirus does have distinct advantages over host-based, including the ability to protect devices incapable of running agents.

Host-based antivirus does have the ability to receive and apply newly created signatures via definition updates from the vendor.

Network-based AV inspects traffic in transit across the network and is not well-suited to scanning files at rest, which is a primary strength of host-based antivirus.
