B. The service provider core network is required to support SSM.
C. Multicast needs to be enabled only on ABC VRF and is tunneled to participating PE routers in the ABC VRF.
D. The SP core network is required in order to enable the BGP Multicast Address Family on all peering.
E. Multicast is required for the core network in addition to the ABC VRF.

Q107. Refer to the exhibit.
A company has a requirement to provide communication among remote sites via multipoint GRE tunnels. This communication is not working yet. Which is the root cause of this issue?
A. The key that is used on the DMVPN tunnel between the spoke and hub ends does not match. This causes the tunnel to fail.
B. BGP IPv4 multicast address-family is missing between hub and spoke points.
C. The GRE tunnel is not sourced from a physical interface. The DMVPN traffic does not know where to forward packets.
D. The NHRP network ID does not match in the hub and spoke configuration causing NHRP negotiations to fail and the mGRE to stay down.
Answer: D

B. IPsec
C. L2TP
D. GRE
Answer: C
Explanation:
However, while OpenVPN can not be used with VoIP, L2TP can be used for VoIP. Only use this if OpenVPN is not available and you are in need of very high security/encryption.
