NSE7 Advanced Networking and SD-WAN Practice Question
A FortiGate with SD-WAN configured has a Performance SLA monitoring Google DNS (8.8.8.8). The SLA is configured with latency threshold 100 ms and jitter threshold 20 ms. The link is currently meeting both thresholds. The administrator wants to ensure that if the SLA fails, traffic moves to another link. Which SD-WAN rule strategy should be used?
⚠ Common exam trap
A common mix-up: candidates confuse 'Failover (SLA)' with 'Best quality', thinking that any SLA degradation should trigger a switch, but Best quality would switch even if thresholds are still met, while Failover (SLA) only switches upon threshold violation.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Failover (SLA)
The Failover (SLA) strategy is correct because it ensures that traffic is moved to another link only when the Performance SLA fails, while the primary link is used as long as it meets the configured latency (100 ms) and jitter (20 ms) thresholds. This strategy provides deterministic failover behavior, matching the administrator's requirement to switch traffic only upon SLA failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Best quality
Why it's wrong here
Best quality selects the best link among those meeting SLA; if no link meets SLA, it uses the best one available.
- ✗
Manual selection
Why it's wrong here
Manual selection always uses the specified member and does not failover based on SLA.
- ✗
Maximize bandwidth (SLA)
Why it's wrong here
Maximize bandwidth distributes traffic across multiple links that meet SLA; if none meet, it may still use them depending on configuration.
- ✓
Failover (SLA)
Why this is correct
Failover strategy uses the first member that meets SLA; if that fails, it moves to the next member in the list.
