4.17 What is the major feature of the spanning tree constructed by the IEEE 802.1D spanning tree algorithm ? 下列哪個是經由IEEE 802.1D 擴張樹演算法所建造的擴張樹的主要特色 ? |
| It is a minimum cost spanning tree. Thus, the summation of the cost of each link is minimized. 這是一個最低成本擴張樹。也就是擴張樹上的每個鏈結的成本加總值最小. | |
| It is a spanning tree that includes the minimum cost path of each bridge/LAN to the root bridge 這是一個包含每個 橋接器/區域網路 到根橋接器(root bridge)最短路徑的擴張樹. | |
| It is a spanning tree that includes the minimum cost path of each pair of bridges/LANs 此擴張樹將會包含任何一對橋接器/區域網路 之間最少成本的路徑. | |
| It is a minimum delay spanning tree. 這是一個傳輸延遲最小的擴張樹. |
