A technician deploys multiple virtual clients on the same host and connects them through a virtual switch. The clients use peer-to-peer enabled software to share videos amongst each other. Which of th

A VPN concentrator is used to manage secure remote access or site-to-site VPN tunnels, not to regulate internal communication between virtual machines on a single host.

A software-based firewall, whether implemented as a virtual appliance or directly on the host operating system, can inspect and filter network traffic between virtual clients connected to a virtual switch, enforcing rules to ensure only authorized peer-to-peer communication occurs.

A DMZ (Demilitarized Zone) is a network segment used to host public-facing services, isolating them from internal networks, and is not designed for controlling internal peer-to-peer VM traffic.

A Host-based IDS (Intrusion Detection System) primarily detects suspicious activities and alerts administrators, but it does not actively prevent or authorize communication as a firewall does.
