A network administrator has configured source NAT, translating to an address that is on a locally connected subnet.The administrator sees the translation working, but traffic does not appear to come back.What is causing the problem?（）A. The host needs to open the telnet port.B. The host needs a route for the translated address.C. The administrator must use a proxy-arp policy for the translated address.D. The administrator must use a security policy, which will allow communication between the zones.
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
Which three IP multicast group concepts are true?（）A、If a packet is sent to a multicast group address, the multicast frame contains the source multicast address.B、A router does not have to be a member of a multicast group to receive multicast data.C、A router must be a member of a multicast group to send to the group.D、A router does not have to be a member of a multicast group to send to the group.E、If a packet is sent to a multicast group address, all members of the multicast group will rece ive it.F、A router must be a member of a multicast group to receive multicast data.
