Network Virtualization

Refer to the exhibit.

Question Image

You have a Contrail deployment that provides cloud services to Customer A. Customer A wants to add a packet-capture service to its network to analyze traffic flowing to and from the Internet.

With reference to the exhibit, which statement is true?

  • A The packet sniffing service must be performed on the edge routers facing the Internet.
  • B The packet sniffing service must be enabled on the vRouter directly attached to the customer’s VM.
  • C The packet sniffing service can be implemented on any physical host in the cloud environment.
  • D The packet sniffing service can be implemented on any switch within the underlay fabric.
Explanation

Contrail mirrors selected traffic to a traffic-analyzer service VM. The vRouter handling the traffic creates and forwards the mirrored copy to the configured analyzer; the analyzer service VM can be placed on a physical compute host elsewhere in the cloud environment. It is not limited to an Internet edge router, the customer VM’s directly attached vRouter, or an underlay switch.
