Which Cisco DNA Center Assurance feature verifies host reachability?
Short answer
A path trace
Question
Key Takeaways
The exam tests your knowledge of Cisco DNA Center Assurance tools, specifically that Path Trace is the feature designed to verify end-to-end host reachability across the network.
Cisco DNA Center Assurance uses the Path Trace feature to verify host reachability by tracing the network path between endpoints. Community consensus overwhelmingly confirms Path Trace as the correct answer for this 350-401 ENCOR/ENARSI exam question.
Common mistake: Some candidates choose 'detail information' (Option C) because viewing detailed host data seems related to reachability, but detail information only displays static host metadata rather than actively tracing and verifying the network path.
Expert Analysis
Why the Answer Is Correct
Path Trace is a Cisco DNA Center Assurance feature that actively traces the path a packet takes from a source to a destination host, verifying reachability at each hop. It uses telemetry data and network topology to identify where traffic is being dropped or delayed. This makes it the definitive tool for confirming whether a host is reachable across the fabric. The feature is highlighted in Cisco Live presentations on DNA Center Assurance troubleshooting.
Why the Other Options Are Wrong
Application Experience (Option B) monitors the performance and health of specific applications rather than verifying general host reachability. Detail Information (Option C) provides static metadata about a client or device, such as IP address, MAC, and connection details, but does not actively test or trace the path. Network Time Travel (Option D) is a historical analysis feature that allows administrators to replay network states from a previous point in time for forensic troubleshooting, not for verifying current host reachability.
Community Comment Notes
All community votes (100%) confirm Option A as the correct answer. Comment [1] references a Cisco Live presentation (BRKNMS-2031) that covers DNA Center Assurance features including Path Trace. Comments [2] and [3] reinforce that Path Trace is the standard tool for verifying host reachability in the DNA Center Assurance dashboard.
Exam Strategy
When you see 'host reachability' in a Cisco DNA Center Assurance question, immediately think of Path Trace. Remember that Assurance features each serve distinct purposes: Path Trace for reachability, Application Experience for app performance, and Network Time Travel for historical analysis.
