Host A opens a Telnet connection to Host B. Host A then opens another Telnet connection to Host
These connections are the only communication between Host A and Host B. The security policy configuration permits both connections.How many sessions exist between Host A and Host B?
A.
1
B.
2
C.
3
D.
4
IMHO the answer is wrong.
Each connection creates its own session (especially when every new connection uses a different SOURCE PORT).
Below the command output from SRX3400 (the scenario given in question was replicated).
You can see two sessions: first served by FPC6, the second by FPC7
root@FW-1> show security flow session destination-port 23 destination-prefix 192.168.200.1
Flow Sessions on FPC6 PIC0:
Session ID: 120468562, Policy name: P4/22, State: Active, Timeout: 1796, Valid
In: 192.168.1.1/48783 –> 192.168.200.1/23;tcp, If: reth2.10, Pkts: 42, Bytes: 4374
Out: 192.168.200.1/22 –> 192.168.1.1/48783;tcp, If: reth0.200, Pkts: 34, Bytes: 4857
Total sessions: 1
Flow Sessions on FPC7 PIC0:
Session ID: 140870820, Policy name: P4/22, State: Active, Timeout: 1798, Valid

Total sessions: 1
The answer should be “2” sessions.
I’m agree it should be 2.
