NSE 8 – Network Security Expert (811) — Question 27

A customer is experiencing problems with a legacy L3/L4 firewall device and the IPv6 SIP VoIP traffic. Their device is dropping SIP packets, consequently, it cannot process SIP voice calls.
Which solution will solve the customer's problem?

Answer options

• A. Replace their legacy device with a FortiGate and deploy a FortiVoice to extract information from the body of the IPv6 SIP packet.
• B. Deploy a FortiVoice and enable IPv6 SIP.
• C. Deploy a FortiVoice and enable an IPv6 SIP session helper.
• D. Replace their legacy device with a FortiGate and configure it to extract information from the body of the IPv6 SIP packet.

Correct answer: A

Explanation

The correct answer is A because replacing the legacy device with a FortiGate allows for better handling of modern SIP traffic, and deploying a FortiVoice provides the necessary functionality to extract information from SIP packets. Options B and C do not address the need for a more capable firewall, while D, while similar, does not involve replacing the outdated device.
