Identify and Resolve LTM Device Issues

Question Image

Refer to the exhibit.

A company uses a complex client software application that connects to one or more virtual servers (VS) hosted on an LTM device. The client software is having issues, and an LTM Specialist must identify the cause.

The LTM Specialist sees a client source IP address of 168.210.232.5 in tcpdump; however, the actual client source IP address is 10.123.17.12.

Why does the IP address 10.123.17.12 not appear in the tcpdump?

  • A The LTM device performed NAT on the individual's IP address.
  • B The Secure Network Address Translation (SNAT) pool on the virtual server is activated.
  • C Network Address Translation (NAT) has occurred in the path between the client and the LTM device.
  • D The individual's data stream is being routed to the LTM device by a means other than the default route.
Explanation

Network Address Translation has translated the client’s private address, 10.123.17.12, to 168.210.232.5 before the packets arrive at the LTM. Consequently, a packet capture on the LTM shows the translated source address rather than the client’s original address.
