[All JN0-231 Questions]

An application firewall processes the first packet in a session for which the application has not yet been identified.

In this scenario, which action does the application firewall take on the packet?

AIt allows the first packet.

BIt denies the first packet and sends an error message to the user.

CIt denies the first packet.

DIt holds the first packet until the application is identified.

Show Suggested Answer

Suggested Answer: D

This is necessary to ensure that the application firewall can properly identify the application and the correct security policies can be applied before allowing any traffic to pass through.

If the first packet was allowed to pass without first being identified, then the application firewall would not know which security policies to apply - and this could potentially lead to security vulnerabilities or breaches. So it's important that the first packet is held until the application is identified.

I'm thinking B is the way to go here. Deny that first packet and let the user know they messed up. Gotta keep those firewalls on lockdown, am I right?

Hmm, I'm pretty sure the correct answer is D. You gotta hold that first packet until you figure out what app it's coming from, right? Don't want any sneaky stuff getting through.
