350-401 Practice Question: Which three statements about Cisco DNA Center…
Which three statements about Cisco DNA Center wireless assurance are true? (Choose three.)
⚠ Common exam trap
Test-takers frequently confuse DNA Center's assurance role with actual control plane functions, leading candidates to believe it replaces the WLC for real-time decisions or requires dedicated hardware, when it is primarily an analytics and assurance overlay.
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
✓
DNA Center collects telemetry from wireless controllers and access points to provide health scores for clients and APs.
Option A is correct because DNA Center's wireless assurance gathers streaming telemetry and statistics from wireless controllers and access points, then aggregates them into health scores for clients, APs, and the wireless network. Option B is correct because DNA Center retains historical client data, allowing administrators to replay past association, authentication, and roaming events to troubleshoot connectivity problems. Option C is correct because DNA Center supports synthetic test clients (sensors) that emulate real client traffic to proactively measure wireless performance such as onboarding, throughput, and latency. Option D is not correct because client association and roaming decisions remain with the wireless LAN controller (or AP in local mode), not DNA Center, which is a management and assurance platform. Option E is not correct because DNA Center does not require a dedicated WLC solely for assurance; it collects telemetry from the existing wireless infrastructure already managed by DNA Center.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
DNA Center collects telemetry from wireless controllers and access points to provide health scores for clients and APs.
Why this is correct
DNA Center's assurance engine ingests streaming telemetry from wireless controllers and access points, then computes per-client and per-AP health scores from that data. This satisfies the stem's requirement for wireless assurance: continuous monitoring and scoring rather than configuration alone, giving visibility into client experience and radio performance across the fabric.
- ✓
DNA Center can be used to troubleshoot client connectivity issues by replaying historical client association events.
Why this is correct
DNA Center's assurance service continuously records client onboarding telemetry, including association, authentication and DHCP events, into its historical repository. Replaying these events lets engineers reconstruct a failed connection attempt step by step, satisfying the stem's troubleshooting requirement without reproducing the fault live.
- ✓
DNA Center uses synthetic test clients (sensors) to simulate client traffic and measure wireless performance.
Why this is correct
Wireless assurance runs synthetic tests through dedicated sensor clients that emulate real client traffic, measuring onboarding, authentication and performance without needing actual users. This active probing complements passive telemetry, satisfying the assurance requirement to simulate client experience.
- ✗
DNA Center replaces the WLC for real-time client association and roaming decisions.
Why it's wrong here
DNA Center performs assurance analytics and monitoring; the WLC retains real-time client association, authentication and roaming decisions. DNA Center is tempting because it centralises wireless management and visibility, but it never takes over the data-plane control role the WLC performs.
- ✗
DNA Center requires a dedicated wireless LAN controller to be deployed solely for assurance data collection.
Why it's wrong here
Assurance data is collected from existing WLCs and access points already integrated with DNA Center; no dedicated controller is required. A dedicated WLC is tempting where telemetry isolation is desired, but DNA Center's assurance architecture consumes existing infrastructure instead.
