You have done a partial migration from 802.1D STP to 802.1w STP. Which of the following is true？（）
A
802.1D and 802.1w interoperate only when the 802.1D STP domain supports rapid convergence.
B
Ports leading to 802.1D devices will run in compatibility mode， while the rest of the ports will run in 802.1w mode.
C
This is an invalid configuration and a partial migration cannot be done.
D
The bridge timers will be set to match the 802.1D devices.
E
A secondary root bridge will always be populated within the 802.1D domain.
F
If the root bridge is selected within the 802.1D domain， the whole STP domain will run in 802.1D compatibility mode.
G
In partially migrated 802.1w networks， it is recommended to keep the STP diameter below 4.

下面哪三种有关RSTP的说法是正确的?()
A.第2层网络拓扑发生变化时，需要重新计算生成树，而RSTP提高了这种计算的速度B.RSTP是一种IEEE标准，重新定义了STP端口角色、端口状态和BPDUC.RSTP极具前瞻性且反应迅速，因此绝对需要802.1d的延迟定时器D.RSTP( 802.1w)优于802.1d，但依然是专用的E.RSTP修改了所有802.1d术语和大部分参数F.为支持传统交换机，可在每个端口上进行配置，让802.1w退化为802.1d

问答题Practice 5Directions: China is now experiencing the largest mass migration of people, an estimated 230 million (2010), from the countryside to cities in history. They’ve brought economy boom to cities and life improvement to their own families. However, this migration leaves land in the countryside uncultivated and children of migrant workers poorly educated. How do you think can the migration in China have a balanced development? For this part, you are allowed 30 minutes to write an essay at least 150 words but no more than 200 words.
