Question 2
Which of the following is a host-centric overlay solution for a modern data center?
- SPBM
- TRILL
- VxLAN
- VPLS
Correct answer: C
Explanation:
Modern data center, traditional technologies are limiting the speed, flexibility, scalability, and manageability of application deployments. There is emerging interest in the industry in overlay technologies (such as MPLS, VXLAN, LISP...)

Question 3
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.
Correct answer: D
Explanation:
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources Reference: https://www.ibm.com/blogs/cloud-computing/2014/02/04/cloud-computing-basics-2/ Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources

Question 4
What statement regarding active/standby VSD cluster is TRUE?
- Both the primary and secondary cluster are running all VSD services.
- XMPP connections to the secondary cluster are blocked.
- The active/standby mode is also supported in standalone VSD.
- VSP components (eg: VSCs) need reconfiguration after failover.
Correct answer: C
Question 5
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
Correct answer: A
Explanation:
The switching fabric is independent of the bus technology and infrastructure used to move data between nodes and also separate from the router. The term is sometimes used to mean collectively all switching hardware and software in a network.

Question 6
What statement is FALSE regarding the relationship between a zone and a subnet within a domain?
- Each zone can have multiple subnets.
- Each subnet can belong to multiple zones.
- A QoS policy defined at the subnet level takes precedence over a QoS policy defined at the zone level.
- A security policy applied to the zone impacts all subnets associated to that zone.
Correct answer: B
Question 7
What does VSD stand for?
- Virtualized Services Description
- Virtualized Services Definition
- Virtualized Services Domain
- Virtualized Services Directory
Correct answer: D
Explanation:

Question 8
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
Correct answer: B

Question 9
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 VPLS.
Correct answer: B
Question 10
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
Correct answer: A
