NO.31 Which of the following is NOT an improvement provided by the backhaul VPLS?

Reducing the number of EVPN on the HV.

Reducing the number of VXLAN tunnels.

Reducing the size of MAC address table.

Reducing the consumption of bandwidth.

NO.32 What statement correctly describes the difference between a managed Layer 2 domain and an undamaged Layer 2 domain?

A managed L2 domain has one or more zones and each zone can have multiple subnets, each with its own IP address pool, while an unmanaged L2 domain does not have zones or subnets.

Managed L2 domains can have overlapping IP address pools, while unmanaged L2 domains are not allowed to have overlapping IP address pools.

In a managed L2 domain, Nuage VCS manages security policies, while in an unmanaged domain, Nuage VCS cannot manage the security policies.

In a managed L2 domain, Nuage VCS performs DHCP and ARP proxy functions, while in an unmanaged domain VCS has no visibility of IP addresses.

NO.33 Which statement is TRUE when comparing Virtual Machines and Containers?

Virtual Machines are faster to boot.

Contained do not need a CMS.

All Virtual Machines on the same hypervisor must run the same guest OS.

All Containers on the same host use the same OS kernel.

NO.34 What three main components comprise the Nuage Networks VCS solution?

VSD, VSC, and VSG

VSD, VSC, and VRS

VNS, VSC, and VSG

VNS, VRS, and VSG

NO.35 What statement regarding VSD user management is TRUE?

We can create CMS user groups for each enterprise.

Each enterprise user belongs to only one user group.

Open LDAP and Active Directory can be integrated into VSD.

LDAP integration is configured at the VSD global level, and it is not configurable enterprise.

NO.36 What statement regarding the VRS-G is FALSE?

The VRS-G is the software VXLAN/VLAN gateway of the Nuage VCS solution.

The VRS-G is deployed on a hypervisor, following the same deployment requirements as a regular VRS.

Virtual machines created on the hypervisor are attached to access ports on VRS-G.

The network ports on VRS-G point towards the Nuage overlay VXLAN network.

NO.37 Which domain can be extended to a 7750 DCI by GRE tunnels?

A managed L2 domain.

An unmanaged L2 domain.

A subnet within an L3 domain.

An L3 domain.

NO.38 Which of the following interfaces does NOT belong to the underlay network?

Interface on VSD

Control Interface on VSC

Openflow interface on VSC

Hypervisor interfaces carrying VXLAN traffic

NO.39 What use case does not apply in virtual machine migration?

Optimization of East-West traffic flows.

Maintenance and upgrading of the servers.

Avoidance of disaster caused by a power outage or hardware failure.

Entry saving by shutting sown under-utilized servers after moving all their VNs.

NO.40 If we compare a Nuage Virtual Service Node to a physical service router, which module is VSC mapped to?

Switch fabric

Line card

CPU module

Internal clock

NO.41 Which statement correctly describes cloud computing?

Services are statically provisioned by a cloud service provider.

Services are offered as needed through the Internet.

SDN is the key enabler for cloud computing.

It provides convenient, permanent network access to a shared pool of computing resources.

NO.42 Refer to the diagram.

What is the correct sequence of events for a VM to be instantiated, and for its required network connectivity to be created with the Nuage VCS solution?
a. Network domain and policy templates are defined on VSD. b.
VSC queries VSD on network service and policies. c. VSD provides VSC with network service and policies. d. VRS agent informs VSC of the new VM placement. e. VSC deploys policy to applicable VRS agents. f. VM instantiated on the hypervisor.

a->b->c->d->e->f

a->b->c->f->d->-e

a->f->d->b->c->-e

f->d->b->a>c->-e

NO.43 What statement about policy groups is FALSE?

Several vPorts ( in the same or different subnets) can be associated with one policy group.

One vPort can be associated with multiple policy groups.

For an ingress security policy, if a hardware endpoint policy group is chosen as the source, the
destination must also be hardware endpoints

The policy group is the syntactic equivalent of the security group used by cloud management
systems.

NO.44 To auto-instantiate services on a 7750 DCI, which protocol needs to be enabled between the 7750 SR and
VSD?

SNMP

Openflow

XMPP

BGP EVPN

NO.45 What statement regarding Openflow sessions in data center networks is TRUE?

By default, the Openflow session is established with TCP port 6633.

Openflow sessions run between VSCs.

Security is mandatory with SSL encryption.

Openflow sessions can be established over either the data plane or the management plane.

NO.46 Which of the following is NOT Nuage Networks metadata required when creating a virtual machine?

Enterprise

Subnet

VLAN ID

User

NO.47 What statement regarding the VRS-G is FALSE?

The VRS-G is the software VXLAN/VLAN gateway of the Nuage VCS solution.

The VRS-G is deployed on a hypervisor, following the same deployment requirements as a regular VRS.

Virtual machines created on the hypervisor are attached to access ports on VRS-G.

The network ports on VRS-G point towards the Nuage overlay VXLAN network.

NO.48 What statement about virtual switches is FALSE?

A virtual switch is typically implemented within the hypervisor so that the network is extended onto the
server.

Virtual switches are VLAN capable.

Typically, virtual switches are as capable as physical switches, eg: LAG, hardware-based QoS.

If a virtual switch is not on the hypervisor, all traffic will go out of the physical NIC.

NO.49 What statement is TRUE regarding multiple virtual IP addresses assigned to a single vPort?

The virtual IP addresses can be in a different subnet than the VM interface IP address.

All virtual IP addresses of a vPort must be in the same subnet.

One of the virtual IP addresses can be the same as the VM interface IP address.

Every virtual IP address must be associated with a virtual MAC, which differs from the VM interface MAC address.

NO.50 Refer to the diagram.

Which statement is describing a step incorrectly?

Step a, which consists of defining network domain and policy templates on VSD, must be performed first in all situations.

Step d, which refers to the VRS agent informing the VSC of the placement of a new VM, is triggered by step f in which the VM is instantiated on a hypervisor.

Step b, in which the VSC queries VSD on network service and policies required for a new VM, is triggered either by API calls from the CMS or by manual configuration.

Step e, in which the forwarding tables are deployed, consists of the VSC sending them not only to the VRS agent hosting the new VM, but to all applicable VRS agents.
