SNAT stands for Source Network Address Translation. It is a type of NAT that translates the source IP address of outgoing packets from a private address to a public address. SNAT is used to allow hosts in a private network to access the internet or other public networks1

In the exhibit, the administrator wants to change the private IP address of the NAT VM 172.16.101.11 to a public address of 80.80.80.1 as the packets leave the NAT-Segment network. This is an example of SNAT, as the source IP address is modified before the packets are sent to an external network.

According to the VMware NSX 4.x Professional Exam Guide, SNAT is one of the topics covered in the exam objectives2
