• Ingress policy acts on traffic flow towards the network (or the OVS component).
• The security policies are defined at the domain level.
• The security policies deployed on the VSD are distributed ACLs implemented on the VRSs and NSGs.

Which of the following is TRUE about NSG dual uplink?

• It only provides redundancy for data traffic.
• Traffic is load balanced between primary and secondary links.
• One primary VSC is selected on each uplink.
