You are the network administrator of an enterprise with a main site and multiple remote sites. Your networkcarries both VOIP and data traffic. You agree with your service provider to classify VOIP and data trafficaccording to the different service RFCs. How can your data and VOIP traffic be marked？（）

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

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

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

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

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

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？（）

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

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

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