[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.

This exam question is making me hungry. I could really go for a nice firewall sandwich right about now. Anyway, I think D is the right call here.

Hah, the firewall's gotta be like, 'Nah, not today buddy!' and just deny that first packet. C is the way to go, no doubt.

I dunno, man. Letting the first packet through just seems like a recipe for disaster. I'm gonna have to go with B on this one.

I'm gonna go with D. Holding the first packet until the application is identified seems like the safest option to me. Can't be too careful with that first packet!

I think the answer is B. The firewall should deny the first packet and send an error message to the user, that way it can analyze the traffic and identify the application before allowing any further packets.
