Question Image

Refer to the exhibit. Communication between the web server and the application server has poor performance. The network engineer must capture the traffic between the two servers, including its payload, for further investigation. The captured data must be sent from the remote site to headquarters. Which action achieves this goal?

  • A Configure NetFlow on N5K-1 to send the data to the monitor server.
  • B Configure SNMP on N5K-1 to send the data to the monitor server.
  • C Configure a SPAN session between N5K-1 and N5K-2.
  • D Configure an ERSPAN session between N5K-1 and N5K-2.
Explanation

ERSPAN mirrors selected traffic, including the original packet contents, and encapsulates the copies so they can traverse a Layer 3/IP network to a remote monitoring destination. NetFlow and SNMP provide flow or management information rather than packet payloads, while local SPAN does not carry mirrored traffic across the routed MPLS path.
