What statement regarding the VRS-G is FALSE?
- A . The VRS-G is the software VXLAN/VLAN gateway of the Nuage VCS solution.
- B . The VRS-G is deployed on a hypervisor, following the same deployment requirements as a regular VRS.
- C . Virtual machines created on the hypervisor are attached to access ports on VRS-G.
- D . The network ports on VRS-G point towards the Nuage overlay VXLAN network.
B
