Refer to the exhibit. You have a non-Cisco switch that is not communicating properly while connected to the distribution-layer Cisco switching fabric.Which two best-practice actions can you take to overcome this problem? （）(Choose two.)A. Turn off MST (802.1s) on all switches.B. Turn on MST (802.1s) on all switches.C. Turn on RSTP (802.1w) on all switches.D. Turn off RSTP (802.1w) on all switches.
Refer to the exhibit. IP multicast for group address 224.1.1.1 has been enabled on all router s in the network. Hosts on Network A receive the multicast traffic. However, hosts on Network B do not. On the basis of outputs provided, what could be the cause of the problem? （）A. The route to 224.69.15.0/24 will be out Ethernet 0B. The reverse path forwarding (RPF) for the route 224.2.0.1 failed to find the interface on which the multicast packet was rece ivedC. Multicast route to 224.69.15.0/24 was added to the mroute table and created by a source directly connected to the routerD. Multicast route to 10.16.0.0/16 was added to the mroute table and created by a source directly connected to the routerE. This router received an IGMP host report from a group member or a PIM join message
