350-401 Practice Question: Is troubleshooting a wireless connectivity issue…
A network engineer is troubleshooting a wireless connectivity issue in a campus network managed by Cisco DNA Center. The Assurance module shows that several access points have high client association failures. The engineer checks the wireless controller configuration and finds that the APs are registered and functional. What is the most likely cause of the association failures?
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
✓
RF interference or poor signal-to-noise ratio on the affected APs.
Cisco DNA Center Assurance can correlate client association failures with RF interference, authentication issues, or configuration mismatches. Since the APs are registered and functional, the issue is likely related to RF interference or signal quality. DNA Center's Assurance can analyze client association events and highlight RF issues as a common cause.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
RF interference or poor signal-to-noise ratio on the affected APs.
Why this is correct
Correct because high association failures are often due to RF issues, which DNA Center Assurance can detect and report.
- ✗
The APs are not running the recommended firmware version.
Why it's wrong here
Incorrect while firmware can cause issues, the APs are registered and functional; association failures are more likely RF-related.
- ✗
The wireless controller has reached its maximum number of APs.
Why it's wrong here
Incorrect because if the controller were full, APs would not register; the scenario states APs are registered and functional.
- ✗
The DNA Center Assurance module is not properly configured to monitor wireless events.
Why it's wrong here
Incorrect because the engineer is already seeing association failure data in Assurance, so monitoring is working.
