Which of the following is true about the MPLS header and its EXP field size？（）

In order to configure two routers as anycast RPs， which of these requirements， af a minimum， must besatisfied？（）

In PIM-SM what control plane signaling must a multicast source perform before it begins to send multicasttraffic to a group？（）

An expanding company is deploying leased lines between its main site and two remote sites. Thebandwidth of the leased lines is 128kb/s each，terminated on different serial interfaces on the main router.These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs，and has therefore reserved sufficient bandwidth in a low latency queue oneach interface for the VOIP traffic. Users now complain about bad voice quality although no drops areobserved in the low latency queue. What action will likely fix this problem？（）

Choose two commands that are required to enable multicast on a router， when it is known that thereceivers use a specific functionality of IGMPv3.（）

What is the correct command to set the router ID for an OSPFv3 process？（）

Which two statements about SA caching are true？（）

Which two are differences between IGMPv2 and IGMPv3 reports？（）

In Layer 2 topologies， spanning-tree failures can cause loops in the network. These unblocked loops cancause network failures because of excessive traffic. Which two Catalyst 6500 features can be used to limitexcessive traffic during spanning-tree loop conditions？（）

Which three options are valid ways to filter routes from a BGP peer？（）
