NSE4 · Question #397

Which of the following statements are true regarding traffic accelerated by an NP processor? (Choose two.)

The correct answer is A. TCP SYN packets are always handled by the NP Processor D. The initial packets go to the CPU, where a decision is taken on if the session can be offloaded. Traffic accelerated by an NP processor means initial packets are processed by the CPU to determine offload eligibility, and TCP SYN packets can be directly handled by the NP processor for new sessions.

Why each option

Traffic accelerated by an NP processor means initial packets are processed by the CPU to determine offload eligibility, and TCP SYN packets can be directly handled by the NP processor for new sessions.

ATCP SYN packets are always handled by the NP ProcessorCorrect

TCP SYN packets can be handled directly by the NP processor if the offloading conditions are met, allowing for rapid session establishment and acceleration.

BThe initial packets go to the NP Processor, where a decision is taken on if the session can be

This is incorrect because initial packets typically go to the main CPU first for policy lookup and offload decisions, not directly to the NP Processor.

CPackets for a session termination are always handled by the CPU.

Packets for session termination (e.g., TCP FIN/RST) are often offloaded to the NP processor as well, not always handled by the CPU, once the session is established and accelerated.

DThe initial packets go to the CPU, where a decision is taken on if the session can be offloadedCorrect

The initial packets of a session are always processed by the main CPU to perform policy lookups, security inspections, and determine if the session meets the criteria for offloading to an NP processor for accelerated handling.
