    In a class of 160 seniors, the ratio of boys to girls is 3 to 5. In the junior class, the ratio of boys to girls is 3 to 2. When the two classes are combined, the ratio of boys to girls is 1 to 1. How many students are in the junior class?

    C

    200

    D

    180

    E

    160


    正确答案： C
    解析：
    因为这个班共有160人，男生和女生的比例为3:5，所以男生和女生的人数分别为(3/8) ×160 = 60人，(5/8) ×160 = 100人。假设另一班男生女生人数共有x人，那么男生女生的人数分别为(3/5)x，(2/5)x，又因为当两班的人数相加后，男生女生的比例相等，所以可得出60 + (3/5)x = 100 + (2/5)x，经计算，x = 200。

    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.
