Question 4

An architect is helping an organization with the Physical Design of an NSX-T Data Center solution.
This information was gathered during a workshop:
There are six hosts and hardware has already been purchased.
Customer is planning a collapsed Management/Edge/Compute cluster.
Each host has two 10Gb NICs connected to a pair of switches.
There should be no single point of failure in any proposed design.
Which virtual switch design should the architect recommend to the organization? (Choose the best
answer.)

  • A. Create a vSphere Distributed Switch (vDS) for Management VMkernel traffic and assign one NIC. Also, create an NSX-T Virtual Distributed Switch (N-VDS) for overlay traffic and assign one NIC.
  • B. Create an NSX-T Virtual Distributed Switch (N-VDS) for Management VMkernel traffic and assign one NIC. Also, create an NSX-T Virtual Distributed Switch (N-VDS) for overlay traffic and assign one NIC.
  • C. Create an NSX-T Virtual Distributed Switch (N-VDS) for Management VMKernel and overlay traffic and assign both NICs.
  • D. Create an NSX-T Virtual Distributed Switch (N-VDS) for Management VMkernel and overlay traffic and assign a new virtual NIC.
