You deployed UBT to securely tunnel traffic from user desktop PCs connected behind VoIP phones. All other non-UBT clients are connected to a different network. After the deployment, users reported interruptions to their phone service. What is the cause of this issue?

3. C. The VoIP multicast group was not created because IGMP snooping is not enabled on the UBT client-assigned VLAN
4. D. The UBT source interface is not configured correctly on the switch interface to support the PC and VoIP traffic simultaneously
