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

Which two are effects of connecting a network segment that is running 802.1D to a network segment that is running 802.1w?()A、the entire network switches to 802.1D and generates BPDUs to determine root bridfe status.B、A migration delay of three seconds occurs when the port that is connected to the 802.1D bridge comes upC、The entire network reconverges and a unique root briddge for the 802.1D segment, and a root bridge for the 802.1W segment, is chosenD、the first hop 802.1w switch that is connected to the 802.1D runs entirely in 802.1DCompatibility mode and converts the BPDUs to either 802.1D or 802.1W segments of the networkE、Classic 802.1D timers, Such as forward Delay and Max-age, will only be used as a backup, and will not be necessary if point-to-point links and edge prots are properly identified and set by the administrator.

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.
