Switching — Cisco CCNA (200-301) Practice Questions
Switching refers to the process by which layer 2 devices (switches) forward Ethernet frames between ports based on MAC address tables, providing high-speed, low-latency connectivity within a local area network. Switches learn MAC addresses dynamically by inspecting source addresses of incoming frames and build a Content Addressable Memory (CAM) table that maps MAC addresses to specific ports. The CCNA exam covers switching extensively, including VLAN configuration, trunk links (802.1Q), inter-VLAN routing, switch security features like port security, and spanning tree behavior. Candidates must be comfortable configuring and troubleshooting Cisco IOS switch features from the command line.
