Question 660 An SLA HTTP test reports a destination as failed because an application changed its expected response path, although the TCP service still works. Which lasting design or operational safeguard best prevents this particular issue from recurring? Use representative remote targets and test failover beyond the first-hop interface. Audit both SLA definitions and schedules before activating tracked routing. Set hysteresis and probe thresholds using observed WAN performance distributions. Review probe endpoint and success logic when applications change. ExplanationCorrect Answer D:Review probe endpoint and success logic when applications change. This addresses the recurring cause: Application-layer SLA success depends on configured request and response expectations, not just network socket reachability. A targeted acceptance check is: Capture the requested URL or response and verify the corrected SLA result matches the application's intended behavior. Other Answers A:Use representative remote targets and test failover beyond the first-hop interface. Application-layer SLA success depends on configured request and response expectations, not just network socket reachability. B:Audit both SLA definitions and schedules before activating tracked routing. Application-layer SLA success depends on configured request and response expectations, not just network socket reachability. C:Set hysteresis and probe thresholds using observed WAN performance distributions.

Question 661 A router's IP SLA operation is configured but never runs because it has not been scheduled to start. Which corrective action most directly resolves the documented failure without suppressing unrelated safeguards? Schedule the probe with an appropriate start time and lifetime, then validate the tracking consumer. Tune approved track down/up delays or probe thresholds based on measured failure duration. Update the IP SLA application probe target and success criterion to match the service health definition. Run the SLA operation in the intended VRF with a source and route context that can reach the target. ExplanationCorrect Answer A:Schedule the probe with an appropriate start time and lifetime, then validate the tracking consumer. An IP SLA definition without active scheduling produces no continuous probe results for dependent tracking. Observe operation runtime state, fresh response history and track transitions under a test outage. Other Answers B:Tune approved track down/up delays or probe thresholds based on measured failure duration. An IP SLA definition without active scheduling produces no continuous probe results for dependent tracking. C:Update the IP SLA application probe target and success criterion to match the service health definition. An IP SLA definition without active scheduling produces no continuous probe results for dependent tracking. D:Run the SLA operation in the intended VRF with a source and route context that can reach the target. An IP SLA definition without active scheduling produces no continuous probe results for dependent tracking.
Question 662 A router's IP SLA operation is configured but never runs because it has not been scheduled to start. Which technical mechanism best explains the behavior observed in this scenario? IP SLA measures configured end-to-end reachability and tracking can withdraw a route despite a locally up interface. An IP SLA definition without active scheduling produces no continuous probe results for dependent tracking. Tracking with immediate state transitions can magnify short probe anomalies into disruptive route oscillations. SLA probes use their configured source/VRF reachability context; success in the global table does not prove VRF reachability. ExplanationCorrect Answer B:An IP SLA definition without active scheduling produces no continuous probe results for dependent tracking. This explains why the initial condition produces the observed failure. The direct repair is: Schedule the probe with an appropriate start time and lifetime, then validate the tracking consumer. Validate through: Observe operation runtime state, fresh response history and track transitions under a test outage. Other Answers A:IP SLA measures configured end-to-end reachability and tracking can withdraw a route despite a locally up interface.

Question 663 A router's IP SLA operation is configured but never runs because it has not been scheduled to start. After applying the correction, which verification evidence most directly demonstrates that this issue is resolved? Capture the requested URL or response and verify the corrected SLA result matches the application's intended behavior. Fail the remote target and observe track Down, primary withdrawal and backup route installation. Observe operation runtime state, fresh response history and track transitions under a test outage. Compare jitter, latency and loss readings with the observed real-time media impairment. ExplanationCorrect Answer C:Observe operation runtime state, fresh response history and track transitions under a test outage. This checks the affected traffic or control-plane behavior, not merely a generic up/down indicator. The underlying mechanism is: An IP SLA definition without active scheduling produces no continuous probe results for dependent tracking.

Question 664 A router's IP SLA operation is configured but never runs because it has not been scheduled to start. Which lasting design or operational safeguard best prevents this particular issue from recurring? Set hysteresis and probe thresholds using observed WAN performance distributions. Review probe endpoint and success logic when applications change. Monitor media-sensitive paths with performance probes rather than binary reachability alone. Audit both SLA definitions and schedules before activating tracked routing. ExplanationCorrect Answer D:Audit both SLA definitions and schedules before activating tracked routing.

Question 665 A flow monitor is defined and attached only in the egress direction, but the analyst expects to see every ingress packet count on the WAN interface. Which corrective action most directly resolves the documented failure without suppressing unrelated safeguards?

Question 666 A flow monitor is defined and attached only in the egress direction, but the analyst expects to see every ingress packet count on the WAN interface. Which technical mechanism best explains the behavior observed in this scenario? NetFlow v9 exports are template-based; a collector cannot interpret data records without matching templates. Flexible NetFlow captures traffic only where a flow monitor is applied and according to its configured direction. The flow record determines which packet fields are keys and which additional fields are collected.
