Question 680 NetFlow records are generated in the router cache but never reach the collector after a management VRF cutover. Which lasting design or operational safeguard best prevents this particular issue from recurring? Agree exporter protocol and schema version with collector owners before cutover. Maintain versioned flow record schemas aligned to analytic requirements. Document traffic observation points and directions in flow-monitoring designs. Test collector reachability from the configured exporter source after VRF changes. ExplanationCorrect Answer D:Test collector reachability from the configured exporter source after VRF changes. This addresses the recurring cause: Flow record capture and export transport are separate; an unreachable collector does not prevent local cache creation. A targeted acceptance check is: Inspect exporter statistics and confirm received records at the collector via the intended VRF. Other Answers A:Agree exporter protocol and schema version with collector owners before cutover. Flow record capture and export transport are separate; an unreachable collector does not prevent local cache creation. B:Maintain versioned flow record schemas aligned to analytic requirements. Flow record capture and export transport are separate; an unreachable collector does not prevent local cache creation. C:Document traffic observation points and directions in flow-monitoring designs.

Question 681 A monitoring system expects IPFIX records but the exporter is configured for an older format lacking required information elements. Which corrective action most directly resolves the documented failure without suppressing unrelated safeguards? Configure the supported IPFIX export format and record fields for the collector's schema. Apply and validate the monitor in the intended supported ingress or egress direction for the desired observation point. Add supported transport port match fields and rebuild the monitor configuration under change control. Fix exporter destination, source interface and VRF routing for the collector path. ExplanationCorrect Answer A:Configure the supported IPFIX export format and record fields for the collector's schema. IPFIX defines template-based information elements beyond fixed older NetFlow layouts. Decode a test export containing the requested information elements in the collector. Other Answers B:Apply and validate the monitor in the intended supported ingress or egress direction for the desired observation point. IPFIX defines template-based information elements beyond fixed older NetFlow layouts. C:Add supported transport port match fields and rebuild the monitor configuration under change control.

Question 682 A monitoring system expects IPFIX records but the exporter is configured for an older format lacking required information elements. Which technical mechanism best explains the behavior observed in this scenario? Flexible NetFlow captures traffic only where a flow monitor is applied and according to its configured direction. IPFIX defines template-based information elements beyond fixed older NetFlow layouts. The flow record determines which packet fields are keys and which additional fields are collected. NetFlow v9 exports are template-based; a collector cannot interpret data records without matching templates. ExplanationCorrect Answer B:IPFIX defines template-based information elements beyond fixed older NetFlow layouts. This explains why the initial condition produces the observed failure. The direct repair is: Configure the supported IPFIX export format and record fields for the collector's schema.

Question 685 Cisco Catalyst Center Assurance shows a device as unreachable even though users can ping it; inventory credentials were changed during a password rotation. Which corrective action most directly resolves the documented failure without suppressing unrelated safeguards? Update the authorized device-management credentials and validate Catalyst Center reachability and collection. Check device discovery and supported telemetry coverage for the missing segment before concluding reachability failed. Correct site/device assignment and inventory scope before interpreting site health results. Inspect relevant client-onboarding and health telemetry rather than treating infrastructure up status as client success.
