The answer is that the SLA target is not configured or not applied to the SD-WAN rule. Without a defined performance SLA, the latency strategy has no benchmark to compare against, so the FortiGate cannot determine when a member is underperforming and thus never triggers a failover. On the Fortinet NSE 7 Advanced Security NSE7 exam, this tests your understanding that SD-WAN rules are not self-monitoring; they rely on explicit SLA targets tied to the rule to evaluate member health. A common trap is assuming the latency strategy alone will automatically switch traffic based on real-time latency values, but without an SLA, the strategy has no threshold to exceed. Remember the key: no SLA means no trigger, so traffic stays on the original member regardless of latency spikes. Memory tip: “No SLA, no play—latency needs a target to switch away.”
NSE7 Troubleshooting and Diagnostics Practice Question
This NSE7 practice question tests your understanding of troubleshooting and diagnostics. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An administrator configures SD-WAN with multiple members. The SD-WAN rule uses the 'latency' strategy. The administrator notices that traffic is not switching to the best-performing member even when latency exceeds the threshold. What could be the issue?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SLA target is not configured or not applied to the SD-WAN rule
Option D is correct. SD-WAN rules require performance SLA targets to be configured and linked to the SD-WAN rule. Without an SLA, the latency strategy has no performance benchmark to trigger failover.
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.
✓
The SLA target is not configured or not applied to the SD-WAN rule
Why this is correct
Without SLA, performance monitoring is not active, so latency strategy has no data to act on.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The load balancing algorithm is set to 'source-ip-based'
Why it's wrong here
SD-WAN rules override load balancing; the algorithm applies only when no SD-WAN rule matches.
✗
The threshold is set too low
Why it's wrong here
A low threshold would cause more switching, not less.
✗
The SD-WAN members are in different VDOMs
Why it's wrong here
SD-WAN members must be in the same VDOM; if they weren't, the configuration would fail.
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.

What is the correct answer to this question?
The correct answer is: The SLA target is not configured or not applied to the SD-WAN rule — Option D is correct. SD-WAN rules require performance SLA targets to be configured and linked to the SD-WAN rule. Without an SLA, the latency strategy has no performance benchmark to trigger failover.
