TurK-FX

Here is the jncis-sec exam objectives => https://www.juniper.net/us/en/training/certification/resources/jncis-security/
I am studying from Juniper SRX series book.

[FONT=&quot]Which chapters cover the below parts?

• Major hardware components of SRX Series services gateways
• Packet flow
• Packet-based vs. session-based forwarding

[/FONT]

I think major hardware components were in chapter 1 and maybe chapter 2?

Packet flow is part of part of security policies?

Packet-based vs Session based forwarding also part of security policies chapter?
