The answer is that the performance SLA does not have latency as the first metric in the priority order. The 'best quality' strategy selects the WAN member with the highest priority metric, and by default, jitter and packet loss are evaluated before latency. Even if the SLA shows both members as alive, the FortiGate will prefer a link with lower jitter or packet loss over one with lower latency unless latency is explicitly moved to the top of the metric priority list. This question tests your understanding of SD-WAN rule strategy logic on the Fortinet NSE 7 Advanced Security NSE7 exam, where a common trap is assuming 'best quality' automatically equals lowest latency. To avoid this, remember that the SLA priority order dictates the tiebreaker—latency is not king unless you crown it. A useful memory tip: "First in the list, first in the link."
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 configures SD-WAN on a FortiGate with two WAN members (port1, port2). They set up a performance SLA to measure latency to 8.8.8.8. The SLA shows both members are 'alive'. However, traffic matching an SD-WAN rule with 'best quality' strategy is not using the lowest-latency link. What is the MOST likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The performance SLA does not have 'latency' as the first metric in the priority order
The 'best quality' strategy selects based on the highest priority metric. By default, latency is not the highest priority; jitter and packet loss are considered first. The admin must configure the SLA to prioritize latency or adjust the SD-WAN rule strategy.
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.
✗
Both WAN members have the same cost in the SD-WAN configuration
Why it's wrong here
Cost is used for lowest-cost strategy, not best quality.
✗
The SD-WAN rule is configured with 'manual' strategy
Why it's wrong here
Manual strategy requires explicit interface selection, not best quality.
✗
The SD-WAN rule has 'set-match' enabled for source IP
Why it's wrong here
Set-match is for load balancing, not best quality; it doesn't affect metric-based selection.
✓
The performance SLA does not have 'latency' as the first metric in the priority order
Why this is correct
Best quality uses the configured metric order; if latency is not first, another metric determines the selection.
Clue confirmation

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.

Variation 1. An administrator configures SD-WAN with two members (port1 and port2). A performance SLA monitors latency to 8.8.8.8. The SD-WAN rule uses 'Best Quality' strategy based on latency. When the link on port1 becomes slow, the FortiGate continues using port1 even though port2 has lower latency. What is the most likely cause?
medium
A.The FortiGate is not receiving ICMP replies from 8.8.8.8
B.The SD-WAN rule is configured with 'Manual' strategy
✓ C.The performance SLA is not associated with the SD-WAN members
D.The load balancing algorithm is set to 'volume' instead of 'lowest-latency'
