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

A switch that is to be added to the production network has been preconfigured （trunks， VLANs， VTP， and STP） and was tested in your lab. After installing the switch into the network， the entire network went down. What might explain what happened？ （）A、The new switch happened to be running Cisco Catalyst operating system， while the other network switches were running Cisco IOS Software.B、The configuration revision of the new switch was higher than the configuration revision of the production VTP domain.C、The link costs on the new switch are set to a high value， causing all ports on the new switch to go into a forwarding mode and none into blocking mode， thereby causing a spanning-tree loop.D、The ports connecting to the two switches have been configured incorrectly. One side has the command switchport mode access and the other switchport mode trunk.

考题
Before inserting a new switch in the network，the network administrator checks that the VTP domain name is correct，the VTP mode is set to server， and revision is lower than the switches in the network. The administrator then configures interfaces and trunks，erases existing VLANs，and connects the switch to the network. Following that procedure，there is no connectivity in the network. What is a possible cause of this problem？（）A、Because the configuration revision of the new switches is lower than the rest of the network， it can change the VLAN database of the other switches.B、As a VTP server， the new switch deleted all VLANs of the network.C、Erasing VLANs increases the VTP configuration revision.D、Since the configuration revision of the network is higher than the new switch， the VLAN database was automatically synchronized.
