A packet that is already associated with a current session arrives at the firewall.
What is the flow of the packet after the firewall determines that it is matched with an existing session?

What is the flow of the packet after the firewall determines that it is matched with an existing session?
When a packet that is already associated with a current session arrives at the firewall, it is sent through the fast path because session establishment is not required. If subject to content inspection, it will pass through a single stream-based content inspection engine before egress. This ensures efficient processing and reduces latency by avoiding repeated inspection steps.
D is correct
it's D - "stream-based content inspection" https://www.paloaltonetworks.com/resources/whitepapers/single-pass-parallel-processing-architecture
https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClWFCA0 the single pass software in our next-generation firewalls scans content once and in a stream-based fashion to avoid latency introduction
That's the idea of single pass software inspection
