第1题：

Which two of the following values does STP take into consideration when it elects the root bridge? (Select two answer choices)

A. The BPDU version number

B. The access layer bridge setting

C. The Bridge ID

D. The spanning-tree update number

E. The bridge priority

F. The VLAN number


正确答案：CE
C,E 解析：Explanation:
The bridges elect a root bridge based on the bridge IDs in the BPDUs. The root bridge is the bridge with the lowest numeric value for the bridge ID. Because the two part bridge ID starts with the priority value, essentially the bridge with the lowest priority becomes the root.

For instance, if one bridge has priority 100, and another bridge has priority 200, the bridge with priority 100 wins, regardless of what MAC address was used to create the bridge ID or each bridge/switch.

第2题：

Refer to the exhibit. Why has this switch not been elected the root bridge for VLAN1?()

A.It has more than one interface that is connected to the root network segment.

B.It is running RSTP while the elected root bridge is running 802.1d spanning tree.

C.It has a higher MAC address than the elected root bridge.

D.It has a higher bridge ID than the elected root bridge.
