Which three options are considered in the spanning-tree decision process? (Choose three.)
A.
Lowest root bridge ID
B.
Lowest path cost to root bridge
C.
Lowest sender bridge ID
D.
Highest port ID
E.
Highest root bridge ID
F.
Highest path cost to root bridge
Explanation:
Configuration bridge protocol data units (BPDUs) are sent between switches for each port.
Switches use s four step process to save a copy of the best BPDU seen on every port. When a
port receives a better BPDU, it stops sending them. If the BPDUs stop arriving for 20 seconds
(default), it begins sending them again.
Step 1 Lowest Root Bridge ID (BID)
Step 2 Lowest Path Cost to Root Bridge
Step 3 Lowest Sender BID
Step 4 Lowest Port IDCisco General Networking Theory Quick Reference Sheets
