Question 7

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.

Question 10

Refer to the diagram.

Which statement is describing a step incorrectly?

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