In Layer 2 topologies， spanning-tree failures can cause loops in the network. These unblocked loops cancause network failures because of excessive traffic. Which two Catalyst 6500 features can be used to limitexcessive traffic during spanning-tree loop conditions？（）

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？（）
