PSE-PLATFORM · Question #288
Which two options prevent the firewall from capturing traffic passing through it? (Choose two.)
The correct answer is B. The traffic is offloaded. C. The traffic does not match the packet capture filter. Offloaded traffic bypasses the firewall's data plane processor entirely - it's handled at the hardware/ASIC level - so the capture engine never sees it, making B correct. C is correct because Palo Alto packet capture relies on user-defined filters (source/destination IP, port…

Explanation
Offloaded traffic bypasses the firewall's data plane processor entirely - it's handled at the hardware/ASIC level - so the capture engine never sees it, making B correct. C is correct because Palo Alto packet capture relies on user-defined filters (source/destination IP, port, protocol); traffic that doesn't match simply isn't captured by design.
A is wrong because multi-vsys mode doesn't block packet capture - you can still capture traffic within each vsys context; it's an administrative separation, not a capture restriction. D is wrong because there is no CPU threshold that automatically disables packet capture; high DP CPU may degrade performance, but 50% is not a capture-blocking condition.
Memory tip: Think "Off and Out" - traffic that is Offloaded (hardware-fast-pathed) or falls Outside the filter is invisible to the capture engine. Everything else the firewall processes in software is fair game.
