[All NSE7_NST-7.2 Questions]

Exhibit.

Refer to the exhibit, which contains the partial output of the get vpn ipsec tunnel details command. Based on the output, which two statements are correct? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: A, C

Anti-replay Enabled:

The exhibit shows replay: enabled, which confirms that anti-replay is enabled for this IPsec tunnel. Anti-replay is a security feature that prevents replay attacks by ensuring that packets are not duplicated or reused.

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?

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.

The different SPI values could indicate a problem with the phase 2 selectors. I'd want to investigate that further.

Hmm, the anti-replay being enabled makes sense. But I'm not sure about the npu_flag values - I'll have to double-check the documentation on that.

I agree with you, Loren. Option D might also be correct because of the SPI values.
