Question 1100
An operations group at a service-provider edge resolved: A branch health monitor shows packet loss rising above the configured SLA but an engineer expects automatic reroute only when latency and jitter also exceed limits. Which ongoing safeguard should become part of its change process?
Explanation
Correct Answer
Test loss, latency and jitter independently for each SD-WAN SLA profile. This control reduces recurrence of the documented mechanism: An individual quality metric can exceed its threshold without other metrics failing. It creates a repeatable check around the needed response: Review the Path Quality OR-based threshold behavior and correct overly strict or lax individual values.
Incorrect Answers
Perform object visibility checks before multi-folder SD-WAN pushes. That safeguard addresses another potential failure: A new site receives an SD-WAN rule that references a Path Quality profile from another folder, causing validation failure. It is not the most targeted recurring control for the described cause: An individual quality metric can exceed its threshold without other metrics failing.
Audit forced-path exceptions against live SLA measurements. That safeguard addresses another potential failure: A branch has a high-quality private link and degraded broadband link, but a hard-coded app route forces voice over broadband despite better available private connectivity. It is not the most targeted recurring control for the described cause: An individual quality metric can exceed its threshold without other metrics failing.
Review LTE usage and policy matching after carrier plan changes. That safeguard addresses another potential failure: A backup cellular path has a strict data quota but the traffic distribution rule treats it as an equal active link for routine video uploads. It is not the most targeted recurring control for the described cause: An individual quality metric can exceed its threshold without other metrics failing.
