Refer to the diagram.

Which statement is describing a step incorrectly?

• A.Step 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.
• B.Step a, which consists of defining network domain and policy templates on VSD, must be performed first in all situations.
• C.Step 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.
• D.Step 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.

What occurrence is NOT a problem facing a traditional data center network?

• A.High latency for some applications.
• B.High packet loss due to the use of the 3-tier hierarchy.
• C.About half of the bandwidth is not used due to links being disabled by STP.
• D.Sub-optimal traffic flow.

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

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

Which two elements of the Nuage Networks VCS Solution act respectively as the control and data plane of a virtual router?

• A.VSC and VRS
• B.VSD and VSG
• C.VSD and VSC
• D.VSC and VSG

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.Server virtualization requires a software upgrade of the network devices (for example, TOR/EOR switch, leaf and spine routers) in a traditional datacenter network.
• D.Traditional network configuration involves manual interaction, which cannot keep up with the dynamic reallocation of compute resources to virtual machines.
