NSE 7 – SD-WAN 6.4 — Question 48

An administrator is troubleshooting VoIP quality issues that occur when calling external phone numbers. The SD-WAN interface on the edge FortiGate is configured with the default settings, and is using two upstream links. One link has random jitter and latency issues, and is based on a wireless connection.
Which two actions must the administrator apply simultaneously on the edge FortiGate to improve VoIP quality using SD-WAN rules? (Choose two.)

Answer options

• A. Select the corresponding SD-WAN balancing strategy in the SD-WAN rule.
• B. Choose the suitable interface based on the interface cost and weight.
• C. Use the performance SLA targets to detect latency and jitter instantly.
• D. Place the troublesome link at the top of the interface preference list.
• E. Configure an SD-WAN rule to load balance all traffic without VoIP.

Correct answer: A, C

Explanation

Selecting the correct SD-WAN balancing strategy (Option A) allows the system to effectively manage traffic based on current conditions, while using performance SLA targets (Option C) helps in actively monitoring latency and jitter for immediate adjustments. Options B and D do not directly address VoIP quality issues, and Option E is counterproductive as it ignores VoIP traffic that needs prioritization.
