1. 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

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

Checking metadata.

Creating a virtual port.

Building a forwarding table

Assigning an IP address.

3. 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

4. Which two elements of the Nuage VCS solution act respectively as the control and data plane of a virtual router?

VSD and VSC

VSC and VRG

VSC and VRS

VSD and VSG

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

Domain- VPRN service instance

Zone-VPLS service instance

Subnet-VPRN service instance

Virtual machine -SAP

6. What statement is TRUE regarding the workflow for live migration of a virtual machine with Nuage VCS?

Only the destination hypervisor’s VRS agent notifies the VSC of the VM migration.

Both the source and destination hypervisor’s VRS agents notify the VSC of the VM migration.

VSD is not notified of the VM migration.

CMS (if used) is not notified of the VM migration.

7. Which of the following is NOT a goal of NFV?

Reduce equipment cost

Faster time-to-market for new services

Efficiency through automation

Increase network bandwidth

8. 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 VR

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

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

9. What is NOT a function of the VSC?

CMS integration

SDN controller

BGP federation

XMPP communication with VSD

10. What statement is TRUE regarding a redundant redirection target?

By default, high availability is enabled for all redirection target.

A redundant redirection target can have only 1 virtual I

We can associated at maximum 2 vPorts with a redundant redirection target.

Traffic will be redirected to all of the vPorts within a redundant redirection target.

11. 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 VS

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

12. 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.

13. What statement is TRUE regarding service chaining provided by Nuage VCS?

Service chaining is flow-based traffic redirection.

Service chaining only works for virtual appliances.

A virtual firewall is required to perform service chaining.

It consists of packets being forwarded by the local VPLS, then through the enterprise VPRN and lastly the backhaul VPL

14. What benefits does virtualization bring to a data center?

Mobility, flexibility, and better resource utilization.

Multitasking with prioritized process scheduling.

More processing power, memory and disk space.

Higher bandwidth, control plane simplification and reduced forwarding tables.

15. What statement is TRUE regarding the security policies provided by Nuage VCS?

The match criteria in security policies can be based on MAC address, IP address and TCP/UDP port number.

Each policy entry has an associated priority that defines the order in which policy entries are evaluated.

Ingress security policy controls the traffic flowing into the virtual machine.

The default ingress security policy allows all traffic to be forwarded.
