NSE7 Advanced Networking and SD-WAN Practice Question
A FortiGate is configured with SD-WAN and uses performance SLA to monitor link quality. The administrator sets the SLA threshold to jitter < 30ms. If a link has average jitter of 35ms, what is the status of that link in the SD-WAN health check?
⚠ Common exam trap
Test-takers frequently confuse 'Degraded' with 'Dead' or 'Unavailable', not realizing that exceeding a threshold (like jitter > 30ms) only degrades the link, while complete probe failure is required for a 'Dead' status.

Correct answer & explanation
✓
Degraded
In FortiGate SD-WAN, when a link's measured jitter exceeds the configured Performance SLA threshold (30ms) but does not fail the SLA entirely, the link is marked as 'Degraded'. The SLA threshold defines the acceptable quality; exceeding it means the link is still alive but not meeting the desired performance, hence degraded.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Dead
Why it's wrong here
Dead means the link is unreachable.
- ✗
Unavailable
Why it's wrong here
Unavailable is not a standard SD-WAN health status.
- ✓
Degraded
Why this is correct
Degraded means the link does not meet one or more SLA thresholds.
- ✗
Alive
Why it's wrong here
Alive means the link passes all thresholds.
