Correct answer: A
Explanation
- root@SRX> show security flow session
- Session ID: 2706, Policy name: Internet-Access/5, Timeout: 2, Valid
- In: 10.0.20.11/1807 --> 4.2.2.2/2370;icmp, Conn Tag: 0x0, If: ge-0/0/1.0, Pkts: 1, Bytes: 84,
- Out: 4.2.2.2/2370 --> 10.0.30.10/24987;icmp, Conn Tag: 0x0, If: ge-0/0/0.0, Pkts: 1, Bytes: 84,
Here the source IP address 10.0.20.11 is being translated to 10.0.30.10 - this is an example of source NAT
