When two bridges are competing for the root bridge of an IEEE 802.1D spanning tree and both have the same bridge priority configured， which parameter determines the winner？（）
Multicast is being deployed in the network， and only ip pim sparse-dense mode has been configured on all interfaces in the network to support a new video streaming application. No other multicast configuration was applied anywhere in the network. Since enabling multicast， the network monitoring tools show periodic spikes in link utilization throughout the network， even in areas where the video application is not being used. What could be a possible cause？（）
Which QoS mechanism can help classify different kinds of Citrix traffic （print job versus real-time terminal control）？（）
