Nokia Nuage Networks Virtualized Network Services (VNS) Fundamentals 4A0-N02 Exam Dumps: Updated Questions & Answers (October 2025)

These two NSGs exchange OpenFlow-TLS with their controller to establish the tunnel for overlay traffic.

These two NSGs must be managed by the same VSD/VSD HA cluster.

The overlay tunnels established between the NSGs must be VXLAN encapsulation.

The overlay tunnels are established during bootstrapping.

NSG vPorts are associated with access ports.

There are four types of vPorts: VM, container, host and bridge.

The NSG’s vPorts are typically host vPorts.

One vPort can only belong to one subnet or L2 domain.

It runs directly on any Linux-based bare metal server.

It is packaged as a docker container.

It is deployed as a KVM, Hyper-V or ESXi virtual machine.

It must be hosted in a public cloud such as AWS.

A security policy is composed of entries defining the conditions to redirect a packet.

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.

The VSD in the data center and the VSD for the branch office are running XMPP to synchronize with each other.

The VSC in the data center and the VSC for the NSG branch office are running BGP to update each other’s forwarding table.

With integration, the virtual machines in the data center and the devices in the branch office can belong to the same overlay network.

Traffic between the virtual machines in the data center and the devices in the branch office are forwarded in VXLAN tunnels.

It encrypts and encapsulates the VXLAN traffic.

The key for IPsec needs be manually configured on NSGs and must match each other.

The IPsec tunnel can be directly terminated by VRS in a data center.

To have IPsec VPN, an encryption function needs to be enabled at each individual NSG.

An ‘overlay network’ is a virtual abstraction built on top of an existing physical network.

Both VXLAN and TRILL are host-centric overlay solutions.

Nuage Networks VNS uses a VXLAN-based overlay solution.

Overlay networks are totally transparent to their physical underlay network.

Forwarding policies can be applied to ingress and egress traffic.

Redirection targets should be created in advance and associated with vports.

Redirection targets cannot be associated with bridge vports (physical appliances).

Traffic between two branch offices or between two devices in the same branch office can be redirected to an appliance located in the data center.
