NPU Acceleration:

The NPU acceleration: encryption (outbound) decryption (inbound) line indicates that Network Processing Unit (NPU) acceleration is used.

The npu_flag for this tunnel is 02. This indicates that encryption and decryption are handled by the NPU, improving the performance of the VPN tunnel.

I'm going with A and D. The anti-replay being enabled is a good sign, and the SPI values are definitely worth looking into further.

Wait, what's an 'npu_flag' anyway? Is that some kind of secret Naruto ninja move?

A and D seem like the correct answers to me. The other options don't seem quite right based on the output.

I think A and D are the correct answers too. The output clearly shows anti-replay is enabled and different SPI values due to auto-negotiation being disabled.
