Which of these statements about penultimate hop popping are true？（）

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

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？（）
