Which of the following components must be elected before the Spanning Tree Protocol can converge in a switched LAN?
A. Designated ports.
B. Duplex operating mode.
C. Fast mode ports.
D. Root bridge.
E. Root ports.
F. BDPU priority.
选项
答案
A,D,E
解析
Explanation:
Designated port: Either a root port or a port that has been determined as having the best (lower) cost-a designated port will be marked as a forwarding port.
Root bridge: The root bridge is the bridge with the best bridge ID. With STP, the key is for all the switches in the network to elect a root bridge that becomes the focal point in the network. All other decisions in the network-like which port is to be blocked and which port is to be put in forwarding mode-are made from the perspective of this root bridge.
Root port: Always the link directly connected to the root bridge, or the shortest path to the root bridge. If more than one link connects to the root bridge, then a port cost is determined by checking the bandwidth of each link. The lowest cost port becomes the root port.
So these three components must be elected before the spanning tree protocol can converge in a switched LAN
