Module 2 Summary and Common Pitfalls

→ A VLAN existing on one switch doesn't help unless it's also configured on every switch in the path, connected via properly configured trunks.
→ Native VLAN mismatch is a subtle, frequently tested misconfiguration — always double-check both ends of a trunk match.
→ Do not confuse root guard (prevents an unauthorized device from becoming root) with BPDU guard (disables a port entirely if any BPDU appears, protecting access ports).
→ LACP requires at least one side configured as active — two passive sides will never negotiate a bundle.
→ Autonomous vs. lightweight AP architecture is a foundational distinction that everything else in wireless design builds on — lightweight-with-WLC is the standard enterprise answer unless a question specifically describes a very small, simple deployment.
