How does an IPv6 router deal with a packet that is larger than the outgoing interface MTU？（）

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？（）

Which types of prefixes will a router running BGP most likely advertise to an IBGP peer， assuming it is notconfigured as a route reflector？（）

What is the command to configure RSVP to reserve up to one-tenth of a Gigabit link，but only allow eachindividual flow to use 1 MB/s？（）

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

When STP UplinkFast is enabled on a switch utilizing the default bridge priority， what will the new bridgepriority be changed to？（）

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

All of these are fundamental building blocks of differentiated services Traffic Conditioner Block exceptwhich one？（）

The classic Spanning Tree Protocol （802.1 D 1998） uses which sequence of variables to determine thebest received BPDU？（）
