What statement about Open vSwitch is TRUE?

• A.It is a standard virtual switch that can run on any operating system.
• B.It provides tunneling mechanisms, for example: VXLAN.
• C.It can only be configured using Openflow by an SDN controller.
• D.It supports most of the open protocols, for example: OSPF, BGP.

What statement about the Nuage Networks VCS solution is FALSE?

• A.It virtualizes and automates the datacenter network infrastructure.
• B.It requires a specific architecture for its networking hardware infrastructure.
• C.The SDN controller of Nuage Networks VCS, is based on the Nokia 7750 SR OS, which is a proven and highly reliable software component.
• D.It leverages a variety of open source components such as Openflow and Libvirt.

What statement regarding active/standby VSD cluster is TRUE?

• A.XMPP connections to the secondary cluster are blocked.
• B.VSP components (eg: VSCs) need reconfiguration after failover.
• C.The active/standby mode is also supported in standalone VSD.
• D.Both the primary and secondary cluster are running all VSD services.

What information is included in the VTEP (virtual tunnel endpoint) forwarding table?

• A.The remote VM MAC addresses, the VXLAN ID (VNI) and the remote VTEP.
• B.The remote VM IP addresses, the VXLAN ID (VNI) and the remote VTEP.
• C.The remote VM IP addresses, the VXLAN ID (VNI) and the local VTEP.

What impact does server virtualization have on a traditional datacenter network?

• A.Traffic between the virtual machines must be carried in the overlay network, which is not supported by a traditional datacenter network.
• B.Server virtualization requires a hardware upgrade of the network devices (for example, TOR/EOR switch, leaf and spine routers) in a traditional datacenter network.
• C.Traditional network configuration involves manual interaction, which cannot keep up with the dynamic reallocation of compute resources to virtual machines.
• D.Server virtualization requires a software upgrade of the network devices (for example, TOR/EOR switch, leaf and spine routers) in a traditional datacenter network.
