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

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

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？（）

Which two statements about SA caching are true？（）

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

Which message type is constructed and sent from an MSDP router to its MSDP peers when it receives a PIM register message knowing that the MSDP router is also configured as an RP for the PIM domain？（）

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

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

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