Which of the following network topologies should an administrator use to segment traffic?

A Metropolitan Area Network (MAN) is a geographic network type spanning a city or campus and describes physical or logical coverage area, not a segmentation mechanism.

A Local Area Network (LAN) is a general term for a network covering a limited area such as a building; it describes scope rather than providing a method to segment traffic within that area.

VLANs operate at Layer 2 and partition a switched network into separate broadcast domains without requiring additional physical hardware. An administrator assigns switch ports or uses 802.1Q tagging to isolate groups of devices so that traffic from one VLAN cannot reach another without passing through a Layer 3 router or firewall, providing both segmentation and security.

A Wide Area Network (WAN) connects geographically dispersed networks over long distances and is a coverage classification, not a tool for segmenting traffic within a local environment.
