单选题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？（）A
mark VOIP traffic with IP precedence 6 and configure only fair-queue’ on the linksB
configure the scheduler allocate 3000 1000 command to allow the OoS code to have enough CPU cyclesC
enable class-based traffic shaping on the VOIP traffic classD
enable Layer 2 fragmentation and interleaving on the linksE
enable Frame Relay on the links and send voice and data on different Frame Relay PVCs

单选题You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network. It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also， if the local OSPF route goes away， the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）A
static route needs to be addedB
floating static route needs to be addedC
bgp backdoor commandD
ospf backdoor command
