What does the OSPF command capability vrf-lite achieve？（）

Internet Protocol version 6 （IPv6） is the next-generation Internet Layer protocol for packet-switched internetworks and the Internet. IPv6 router solicitation is（）

For the following protocols， which one provides a mechanism to transparently intercept and redirect CIFS traffic from a client to a local Cisco Wida Area Application engine？（）

Phase I and Phase II DMVPN differ in terms of which of these characteristics？（）

Which three are needed to run VRF lite for IPv6 on a router？ （）

Which QoS mechanism can help classify different kinds of Citrix traffic （print job versus real-time terminal control）？（）

Which switch port error is an indication of duplex mismatches on 10/100/1000 IEEE 802.3u  Gigabit Ethernet ports？（）

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？（）

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 router is doing LSA type 7 to type 5 translation，and why？（）
