This overview provides broad guidelines for the type of content that may be included in the exam. Other material not described here may be incorporated into the exam.


  • Describe the Nuage Networks VCS, its components Virtualized Services Directory (VSD), Virtualized Services Controller (VSC) and Virtual Routing and Switching (VRS) and the roles each of them play in the Nuage Networks solution for Software Defined Networking (SDN), as well as their benefits.
  • List the different networks that interconnect the various elements in the Nuage Networks SDN solution (management, underlay and overlay networks), as well as the requirements that each of these networks meets.
  • Describe the Layer 2 and Layer 3 services that need to be automatically created to provide connectivity among virtual machines of a new domain and verify that such services exist.
  • Identify common issues that prevent the proper operation of the Nuage Networks SDN solution, find their root cause and bring the system back to a proper operational state.
  • Identify VSD, VSC and VRS as the different VCS components, and the role they play.
  • Explain VSD service abstractions and the relationship between domain, zones, and subnets as well as the policies that can be applied to each.
  • Explain the functions of the Nuage SDN controller – VSC.
  • Map the VSD service abstractions to the service instances created on the VSC.
  • Describe the XMPP, Openflow and BGP interfaces on VSC.
  • Explain the functions of the Nuage VRS.
  • Describe the key components of the Nuage VRS (VRS agent and OVS) as well as the role played by each.
  • Understand the function and network position of the Nuage VXLAN gateway.
  • Describe the software-based Virtual Routing and Switching Gateway (VRS-G).
  • Describe the hardware-based 7850 VSG/VSA
  • Understand the function and network position of the 7750 Service Router Datacenter gateway.
  • Identify VSAP as a powerful tool to monitor and troubleshoot a VCS managed network.
  • Explain what the management network is, the type of information it carries, and why it is useful.
  • Describe the type of information carried by the XMPP.
  • List the data center devices that need to establish XMPP sessions.
  • Explain what the underlay network is, the type of information it carries, and why it is useful.
  • List the data center devices that need to establish BGP sessions over the underlay network, and the corresponding address families.
  • Describe the type of information carried by the OpenFlow protocol.
  • List the data center devices that need to establish OpenFlow sessions over the underlay network.
  • Explain what the overlay network is, the type of information it carries, and why it is useful.
  • Describe the Layer 2 and Layer 3 services that are automatically created to provide connectivity among virtual machines of a given standard Layer 3 domain.
  • Describe the Layer 2 service that is automatically created to provide connectivity among virtual machines of a given Layer 2 domain.
  • List the types of statistics that can be collected at the domain, zone, subnet and vPort levels.
  • List the types of statistics that can be collected for a specific ACL entry and describe the concept of flow logging.
  • List the information provided by the VSD Management Console that is helpful to monitor the proper operation of the VCS solution
  • List the information provided by the VSD Alarms that may indicate that something is not working properly.
  • Explain why configuring a syslog server is useful for maintaining longterm log files.
  • List the information provided by the VSD, VSC and VRS logs
