Explanation

Switches (A) are the primary devices for physically connecting computers in a VLAN - managed switches use IEEE 802.1Q tagging to segment traffic into logical groups without requiring separate physical infrastructure. Routers (B) are also used because inter-VLAN routing requires a router (or Layer 3 switch) to forward traffic between VLANs, making it a physical participant in the VLAN architecture. Hubs (D) and Repeaters (E) are eliminated immediately - both operate at Layer 1 and simply broadcast or amplify signals with no ability to distinguish or segment traffic. Bridges (C) are Layer 2 devices like switches, but they are outdated, lack VLAN support, and have been functionally replaced by modern managed switches.

Memory tip: Think "Layer matters for VLANs" - VLANs need Layer 2 intelligence (Switch) and Layer 3 routing (Router). Anything operating only at Layer 1 (Hub, Repeater) or lacking VLAN support (Bridge) can't participate in VLAN configuration.
