Refer to the exhibit. Router E learned about the PIM RP （designated as 7.7.7.7） from four different sources. Routers A and D advertised the 7.0.0.0 network via EIGRP. Routers B and C advertised the 7.0.0.0 network via OSPF. Considering that all four Ethernet interfaces on router E could potentially lead back to the PIM-RP， when router E receives the first multicast packet down the shared tree， which incoming interface will be used to successfully pass the RPF check？（）
A. E0
B. E1
C. E2
D. E3
E. None of these interfaces will be used to successfully pass the RPF check.
F. All of these interfaces would successfully pass the RPF check.

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？（）
