B. Next-Generation Firewall usually combines traditional stateful inspection with deep packet inspection and stores detailed info in state tables, so it fits the question well beyond just basic filtering or app layer checks.

Not C, since basic packet filtering only checks headers without storing detailed state info. The question likely points to a tech that goes beyond that, so A or D are better fits.

Option A, since packet filtering (C) doesn’t keep detailed state info at all.

It’s D for me. Application Layer Firewalls dig into the actual content of packets, not just headers, and track state info across sessions. That detailed state tracking goes beyond simple packet filtering or even generic next-gen firewalls. INSPECT Engine is close but feels more like a branded term for stateful inspection, while Application Layer Firewalls are built specifically to store and analyze state info at a deeper level, making D the better fit here.

A/D? INSPECT Engine definitely deals with state tables because it tracks connections deeply. Application Layer Firewall also processes packets in detail, but it’s more about understanding the application data itself rather than just storing state info. Packet Filtering (C) is too basic, and Next-Gen Firewall (B) is broader tech that includes INSPECT but isn’t as specific about state tables. So between A and D, A seems more focused on the state tracking part.

Gotta say, the INSPECT Engine feels right here. A.
