Inter-VLAN routing is the process of forwarding network traffic from one VLAN (Virtual Local Area Network) to another, and the three methods are legacy (multi-interface), router-on-a-stick, and Layer 3 switching with SVIs (Switch Virtual Interfaces). * A Layer 3 switch routing b...

Use router-on-a-stick for small/medium networks (< 50 VLANs (Virtual Local Area Networks)) with existing routers and Layer 2 switches. Use Layer 3 switches for enterprise/campus networks requiring speed and scalability. Feature Router-on-a-Stick Layer 3 Switch Speed Slower...

The IP (Internet Protocol) phone acts as a 3-port switch — it tags its own voice traffic with the voice VLAN and CoS (Class of Service) priority, while PC data traffic goes on the access VLAN. Use show interfaces switchport to verify. * An IP phone as a 3-port switch: voice is t...

1) Every router makes its own independent decision based only on its own routing table. 2) A route in one router's table doesn't mean other routers know the same route. 3) A route to a destination doesn't guarantee a return path exists. * The return-route problem. * Principle...

A metric is a quantitative measure of distance to a network — within one protocol, the path with the lowest metric wins. Administrative distance (AD) is different: it ranks the trust between protocols, deciding which source's route to install when two protocols both know the dest...

The four main threats are: data interception (sniffing), wireless intruders, Denial of Service (DoS), and rogue APs. WLANs are more vulnerable because the medium (radio waves) is open to anyone within range — there's no physical cable to protect. Threat Description Mitigation...
