STP: Understanding the basics of the STP

Understand why the ports are green and amber. Remember that the order of values compared between BPDUs is:

1. Root Bridge ID (= Priority + VLAN + MAC address)
2. Total Root Path Cost
3. Sending Bridge ID (= Priority + VLAN + MAC address)
4. Sending Port ID (= Priority + Port index)
5. Receiving Port ID (=Priority + Port index)

Post that follow will have the same scenario.

VTP is already running. Switch 5(12 o'clock) is the vtp server with domain CISCO and all other the clients. None are in transparent mode for now. 


question is based on the information above which one of these switches is the root??
