Which THREE are valid reasons to use Cisco DNA Center's Assurance APIs in an enterprise network?
⚠ Common exam trap
Cisco often tests the distinction between Assurance (monitoring/analytics) and Automation (configuration/policy enforcement) APIs, leading candidates to mistakenly associate QoS enforcement or NetFlow collection with Assurance when those belong to separate functional domains.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Proactively detect client connectivity issues.
Option B is correct because DNA Center Assurance APIs expose health and issue data (via endpoints like /dna/intent/api/v1/health and /issues) that let you proactively detect client connectivity problems such as onboarding, authentication, or RF failures before users report them. Option D is correct because Assurance correlates application telemetry and client/device health to surface application performance bottlenecks, including per-application experience metrics and Application Experience scores. Option E is correct because Assurance stores historical telemetry and provides trend/analytics APIs that support capacity planning and long-term network trend analysis. Option A is not correct because QoS policy enforcement is a configuration task handled by DNA Center's policy/intent configuration workflows, not the Assurance APIs, which are read/analytics-oriented. Option C is not correct because Assurance does not collect NetFlow from all devices; flow collection is typically done via NetFlow/IPFIX exporters and a flow collector, not through DNA Center Assurance APIs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Automatically enforce QoS policies on switches.
Why it's wrong here
QoS policy enforcement is a configuration function performed through DNA Center's intent-based policy workflows, not the Assurance APIs, which read telemetry for health, client and device insights. It tempts because DNA Center does centralise QoS provisioning, but that belongs to design and policy configuration, not assurance monitoring.
- ✓
Proactively detect client connectivity issues.
Why this is correct
Assurance APIs expose client health and onboarding telemetry, so issues such as failed authentication or poor roaming are surfaced before users report them. This satisfies the proactive detection requirement by flagging connectivity problems across the fabric.
- ✗
Collect NetFlow data from all network devices.
Why it's wrong here
Assurance APIs expose health, client, and path trace data rather than raw NetFlow exports, so collecting NetFlow from every device is not their purpose. It is tempting because Assurance does surface traffic insights, but flow record collection is handled by NetFlow-capable devices and separate collectors.
- ✓
Identify application performance bottlenecks.
Why this is correct
Assurance APIs surface application health metrics, including per-application latency and response time, letting teams pinpoint where performance degrades. This satisfies the requirement to identify application performance bottlenecks across the network rather than only device-level faults.
- ✓
Analyze historical network trends for capacity planning.
Why this is correct
Assurance APIs expose historical telemetry and health scores, enabling trend analysis for capacity planning. This satisfies the stem's requirement for a valid use case, since the platform retains time-series data on device and client performance, letting engineers forecast growth and justify hardware upgrades before utilisation thresholds are breached.
