Which protocol and port have been assigned by IANA for RADIUS authentication？（）

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

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 protocols or applications should be placed in a class that is configured with WRED？（）

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

Based on the output provided in the exhibit， to which address or location will the router forward a packet sent to 192.168.32.1？（）

Based on the exhibit presented. What will be the objective of this route map when applied to traffic passing through a router？（）

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

Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correctBGP session endpoint addresses and the correct BGP session hop-count limit EBGP multihop. What is agood first test to see if BGP will work across the firewall？（）
