The correct answer is A. The multicast group address needs to be changed to a routable subnet. The multicast group 224.0.0.100 is in the 224.0.0.x link-local multicast range, which is not routable.

Question

A customer has connected a server to VLAN 100 on a 6300 switch which is streaming video using multicast group 224.0.0.100. This stream would need to be received by the clients in VLANs 200 and 300, routed on the same CX switch. What needs to be done to enable the requirement?

Options

  • AThe multicast group address needs to be changed to a routable subnet.
  • BThe multicast group address needs to be changed to other 224.0.0x non-overlapping address
  • CThe igmp-snooping needs to be enabled on SVIs 100, 200, and 300
  • DThe igmp needs to be enabled on the SVIs 100, 200, and 300

Explanation

The multicast group 224.0.0.100 is in the 224.0.0.x link-local multicast range, which is not routable. These addresses are restricted to the local VLAN and cannot be forwarded or routed between interfaces on any router or Layer-3 switch. To allow multicast traffic to be routed from VLAN 100 to VLANs 200 and 300, the server must stream to a routable multicast group address (e.g., 239.x.x.x or 232.x.x.x). Therefore, the multicast group must be changed to a routable subnet.
