A ____ is defined as a "logical" grouping of network devices into a single broadcast domain or flat network.

• A. Subnet
• B. VLAN
• C. Domain
• D. Network

Answer: (B)

A VLAN is a logical grouping that creates a single broadcast domain across switches. By placing devices into the same VLAN, they behave as if they’re on the same local network even if they’re physically separated, so broadcast and ARP requests reach all members of that VLAN. This works through tagging frames with a VLAN ID (802.1Q), which keeps traffic in separate VLANs isolated from others while allowing centralized, flexible network design. Subnets relate to IP addressing and routing boundaries, not the layer 2 broadcast-domain concept across multiple switches. A domain or a network is too general to describe the precise idea of a single, flat broadcast domain created by grouping devices into a VLAN.
