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？（）
How does an IPv6 router deal with a packet that is larger than the outgoing interface MTU？（）
Which three options are valid ways to filter routes from a BGP peer？（）
On the basis of the network provided in the exhibit， all routers are configured to run EIGRP on all links. If the link between PG-R1 and PG-R2 fails， what is the maximum number of queries PG-R3 will receive for 192.168.1.0/24， assuming that all the packets sent during convergence are transmitted once （there are no dropped or retransmitted packets）？（）
Which three message types are valid PIMv2 message types？（）
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？（）
