The answer is to ensure the performance SLA measures jitter and to set the SD-WAN rule strategy to 'best quality' with jitter as the highest priority metric. This works because the performance SLA defines the link quality thresholds, and without jitter measurement, the SD-WAN engine has no data to compare; the 'best quality' strategy then dynamically selects the link with the lowest jitter value among those meeting the SLA. On the Fortinet NSE 7 Advanced Security NSE7 exam, this tests your understanding of how SD-WAN rules interact with performance SLAs—a common trap is confusing 'best quality' with 'load balancing' or forgetting that the SLA must explicitly include the jitter metric. Remember the memory tip: "SLA measures, best quality selects"—the SLA gathers the jitter data, and the best quality strategy uses it to pick the optimal path for voice traffic.
NSE7 Advanced Networking and SD-WAN Practice Question
This NSE7 practice question tests your understanding of advanced networking and sd-wan. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator is configuring SD-WAN rules and wants to ensure that voice traffic is sent over the link with the lowest jitter. Which TWO configurations should the administrator apply? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the SD-WAN rule strategy to 'best quality'
To use jitter as the selection metric, the performance SLA must include jitter measurement, and the SD-WAN rule strategy should be 'best quality' with jitter as the highest priority metric.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set the SD-WAN rule strategy to 'lowest cost'
Why it's wrong here
Lowest cost uses administrative cost, not jitter.
✗
Configure the SD-WAN rule to use 'volume' load balancing
Why it's wrong here
Volume is a load balancing algorithm, not related to jitter.
✓
Set the SD-WAN rule strategy to 'best quality'
Why this is correct
Best quality uses the priority order of metrics, which can include jitter.

✗
Enable 'set jitter-threshold' on the SD-WAN rule
Why it's wrong here
Jitter threshold is part of SLA configuration, not the rule itself.
✓
Ensure the performance SLA measures jitter
Why this is correct
Without jitter measurement, the SLA cannot evaluate jitter.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the NSE7 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
