Scenario guide

How to approach vlan and inter-vlan routing scenarios

VLAN misconfiguration is one of the top sources of connectivity failures in real networks and one of the most tested areas on the CCNA. These questions cover VLAN access ports, 802.1Q trunks, native VLANs, and router-on-a-stick or layer-3 switch inter-VLAN routing.

Quick answer

Routing questions usually test route selection (administrative distance, metric), how static routes are configured and when they are preferred over dynamic routing.

Administrative distance comparing routing sources.

Static route configuration: next-hop vs exit interface.

Default route propagation and the gateway of last resort.

Recursive routing table lookups.
