Question 1

What statement regarding the VRS-G is FALSE?

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

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

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

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

Answer : B

This permits the bridging of the hypervisor-focused overlay networking and physical devices in the data center. Reference: https://jujucharms.com/nuage-vrsg/

Question 2

What statement regarding VSC deployment is TRUE?

AVSC can be deployed in standalone mode or in high-availability cluster mode.

BVSC can only be installed as virtual machines.

CVSC is based on SR OS, and thus can be integrated module on the 7750 SR.

DXMPP is used to synchronize the active and standby VSCs.

Answer : D

Question 3

What statement is TRUE regarding the pull and push mode of CMS integration with Nuage Networks VCS?

AIn the push model, VSD pushes the network configuration to CMS.

BIn the pull model, VRS pull the network configuration from CMS.

CIn the push model, CMS pushes the network configuration to VSC.

DIn the pull model, CMS pulls the network configuration from VSD.

Question 4

Refer to the diagram.

Which statement is describing a step incorrectly?

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

BStep 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.

CStep 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.

DStep 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.

Answer : D

Question 5

What task is NOT part of VSD policy evaluation for a newly-instantiated virtual machine?

AChecking metadata.

BCreating a virtual port.

CBuilding a forwarding table.

DAssigning an IP address.

Answer : C

Question 6

Which mapping between a VSD service abstraction and an overlay service instance is correct?

ADomain- VPRN service instance

BZone-VPLS service instance

CSubnet-VPRN service instance

DVirtual machine -SAP

Answer : A

Question 7

What benefits does virtualization bring to a data center?

AMobility, flexibility, and better resource utilization.

BMultitasking with prioritized process scheduling.

CMore processing power, memory and disk space.

DHigher bandwidth, control plane simplification and reduced forwarding tables.
