Correct answer: A
Explanation
- root@SRX> show security flow session
- Session ID: 2711, Policy name: Internet-Access/5, Timeout: 4, Valid
- In: 10.0.20.11/1807 --> 4.2.2.2/2373;icmp, Conn Tag: 0x0, If: ge-0/0/1.0, Pkts: 1, Bytes: 84,
- Out: 4.2.2.2/2373 --> 10.0.30.10/29669;icmp, Conn Tag: 0x0, If: ge-0/0/0.0, Pkts: 1, Bytes: 84,
Here the source IP address 10.0.20.11 has been translated to 10.0.30.10 and the source port 1807 has been translated to 29669 - this is an example of source NAT with PAT
