• Question 54:

  If we compare a Nuage Virtual Service Node to a physical service router, which module is VSC mapped to?

  A. Switch fabric

  B. Line card

  C. CPU module

  D. Internal clock

  Correct Answer: A

  The switching fabric is independent of the bus technology and infrastructure used to move data between nodes and also separate from the router. The term is sometimes used to mean collectively all switching hardware and software in a network.
