Which three statements are true about policing？ （）
You are the network administrator of an enterprise company that just deployed a global IP telephony environment. In order to guarantee good voice quality， you asked your provider to implement QoS on the CE routers of your MPLS network. On your LAN， you have also deployed QoS. Users， however， keep complaining about bad voice quality， and the provider does not see matches on the DSCP values that you have asked him to match upon. What is most likely the problem？（）
For the following ports， which port is on every bridge in a Spanning Tree Protocol IEEE 802.1w network except the root bridge？（）
f a Cisco switch is configured with VTPv1 in transparent mode， what is done with received VTP advertisements？（）
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 two attributes need to match for two switches to become members of the same MST region？ （）
An administrator of a peer-to-peer server application reports that the maximum bandwidth that his application receives is 90 Mb/s. You have an 8-port，100-Mb/s EtherChannel bundle on the switching infrastructure between the two servers， resulting in a bidirectional throughput of more than what is recorded. Which two solutions would allow for more bandwidth for the application？（）
You are the network administrator of a Layer 3 switched network. Users in one VLAN are complaining that access to the server VLAN is very slow from time to time. Traffic in the local VLAN works without any issue， and users in other VLANs do not have any complaint to reach the server VLAN. What is most likely the cause of this issue？（）
When a BGP router is not capable of understanding 4-byte AS numbers， it will see 4-byte AS numbers as a special， reserved， 2-byte AS number in the AS path. Which 2-byte AS number is this reserved one？（）
