A network administrator needs to monitor real-time application performance and path quality metrics for a specific site in Cisco vManage. Which menu should the administrator navigate to?

A network administrator is investigating why application traffic from a branch site is being routed over the less-preferred MPLS transport instead of the local broadband circuit, even though the application-aware routing policy is configured to prefer broadband for that application. The administrator has already verified that the application is correctly identified and that both TLOCs are up. Which vManage monitoring view should the administrator check first to see the per-application path selection decisions and the reason a particular path was chosen?

A network operations team is troubleshooting an intermittent voice-quality complaint at a branch. In vManage they open the Troubleshooting pane for the affected device and run a bidirectional application-aware traffic flow test between the branch and the voice gateway. The test completes successfully, but the team wants to confirm which physical WAN transport and which local interface the simulated flow actually traversed. Where should they look in the test results?

During an incident, an engineer observes that a WAN edge device is dropping traffic on a specific tunnel, and wants to verify the BFD session state and the measured loss and latency for that tunnel. Which operational command on a Cisco IOS XE SD-WAN device provides this per-tunnel BFD detail?

Which mechanism should the engineer verify is properly configured?

An engineer is designing monitoring for a dual-router branch where each router has two WAN transports.

An operator must prove to an auditor that traffic from a branch to a business-critical SaaS application used the preferred low-latency transport over the last 24 hours, and that failover to the backup transport occurred only during a documented outage window. Which vManage monitoring capability provides the per-application, time-correlated evidence needed?

A help desk technician reports that users at a remote site are experiencing slow access to a SaaS application.

An engineer is analyzing an application-aware routing policy on a Cisco SD-WAN fabric. The policy is configured to steer business-critical traffic based on the best path according to BFD probes.
