REST API for Real-Time Application-Aware Routing Monitoring
Short answer
B Use the SLA class REST API call to retrieve real-time statistics for application-aware routing and data plane tunnel performance.
Question
Key Takeaways
It tests the specific mapping between monitoring types and REST API resources, with the common trap being confusion between historical data, alarms, and real-time SLA statistics.
This question tests knowledge of Cisco Catalyst SD-WAN REST API endpoints for monitoring. The correct endpoint for real-time application-aware routing statistics is the SLA class API.
Common mistake: Candidates often select 'history' or 'event', confusing real-time operational statistics with audit trails or system events.
Expert Analysis
Why the Answer Is Correct
The 'SLA class' API (specifically GET /dataservice/device/app-route/sla-class) provides real-time statistics about data traffic characteristics for operational data plane tunnels. This directly supports real-time monitoring of application-aware routing by showing how traffic is performing against defined Service Level Agreement classes.
Why the Other Options Are Wrong
The 'history' endpoint typically retrieves past or accumulated data rather than current real-time status. The 'event' and 'alarm' endpoints are used for tracking system occurrences, errors, or threshold breaches, not for continuous performance monitoring of routing paths.
Community Comment Notes
One user confirmed that 'SLA Class' displays information about SLA classes operating on the router and provides statistics for data plane tunnels. Another comment incorrectly suggested 'event', but the consensus among verified experts points to SLA class for this specific monitoring type.

Exam Strategy
Memorize the specific REST API endpoints associated with different monitoring functions in SD-WAN Manager. Focus on distinguishing between real-time stats (SLA), historical data, and event logging.
