200-301 - Network Access - Section 2.5

Interpret the basic operation of Rapid PVST+ Spanning Tree Protocol, including root bridge and root port election, port roles and states (forwarding/blocking), and PortFast.

Determine which switch becomes the root bridge from the lowest bridge ID (priority then MAC address), then identify each switch's root port by lowest cumulative path cost and the designated and blocking ports that prevent Layer 2 loops. Recognise that PortFast moves an access port straight to forwarding for end devices, and that Rapid PVST+ converges faster than legacy 802.1D.
