FCP – FortiGate Administrator 7.4 — Question 83

Which two statements describe how the RPF check is used? (Choose two.)

Answer options

• A. The RPF check is run on the first sent packet of any new session.
• B. The RPF check is run on the first reply packet of any new session.
• C. The RPF check is run on the first sent and reply packet of any new session.
• D. The RPF check is a mechanism that protects FortiGate and the network from IP spoofing attacks.

Correct answer: A, D

Explanation

The correct answer is A and D. Option A is right because the RPF check is performed on the first packet sent in a new session to verify the source. Option D is also correct as the RPF check is designed to prevent IP spoofing attacks. Options B and C are incorrect because the RPF check is not specifically run on the first reply packet, and it does not apply to both sent and reply packets in this context.
