An SD-WAN lab succeeds after cable removal but fails during high jitter while the port stays up. What gap does that reveal?

Choose the single best answer.

A.The design has not successfully validated quality-based eligibility and fallback under degradation.
B.The cable-removal test proves every application-quality case already works.
C.All members need a shared public IP as the only remedy.
D.Jitter can only be detected by disconnecting the Ethernet cable.

✓ Correct answer

The design has not successfully validated quality-based eligibility and fallback under degradation.

Hard failure and alive-but-degraded quality exercise different conditions. Validate thresholds, targets, steering and fallback under the actual degradation. A shared public IP is not a universal repair, and quality measurement does not require a cable outage.
